Printer Diaries: How stiff is 2020? | Delta 3D Printer | Shorts James Pray 2023-09-14 | I figured out that trussing a pair of 2020 beams, even with printed joiners, can be substantially more stiff than a single 2020 or even a pair that isn't connected. But does my delta's frame need it? Let's break out the dial indicator and find out before all the truss pieces are attached.

Ultimate Duct Design Guide for 3D Printers | My Top 17 Secrets for Custom Cooling Ducts that WORK James Pray 2023-03-08 | This one goes out to all my homies on Discord. Hope you can read fast! This guide is, uh, information-dense, so STRAP IN.I want to emphasize that nozzle design is sort of its own thing and an area I'm still learning. There are lots of ways to set up nozzles besides what you'll see here. This guide is mainly about getting as much airflow as possible at the point of outlet, less about the best way to use it.

First Look: Ultralight Toolchanging-Ready Delta 3D Printer Design James Pray 2023-02-17 | Pushing speed is fun, but so is pushing for new capabilities! I think toolchanging is the next big frontier, so I spent the last two months reworking RocketKossel's motion system from scratch and developing my fabrication skills to get this new design up and running.All printed parts are PLA reinforced with carbon fiber inserts for incredible rigidity. I made my own arms using IGUS self-lubricating joints (these are an experiment and may or may not prove suitable in the long run). Best of all, the center plate of the effector is hand-swappable so it's ready for future toolchanging! The kinematic coupling is different than the most common 3-balls-on-six-rods system, but it should be good enough -- testing will show one way or the other, and I left room to change it if it's not suitable. Early days!The effector uses no metal hardware at all except for the heatsert the Pico hot end threads into, so it weighs in at a (ridiculous?) 60g ready-to-print. The carriages each weigh just 36.5g including the 9C linear bearings. The arms are 6mm CF tubes with 4mm CF rods glued into the drilled-out IGUS rod ends. Discounting wiring, CPAP hose for remote cooling, and Bondtech LGX flying extruder (which are not hard-coupled moving mass) and the belts (which I have not weighed), the entire motion system INCLUDING HOT END weighs just 240.07g!I want to put some mileage on this new motion system before I change anything else or start exploring actual toolchanging, but that's where things are headed, so stay tuned ... !

EVA Trihorn on 0.8 PSI of Boost 🌪 3D Printed Compressor 2-Stage Prototype Preview | Shorts James Pray 2022-09-02 | Development continues on the 3D Printed Regenerative Compressor prototype, with upgrades to put a compressor on that compressor because I heard you like compressors! Here's a sneak peek at how it performs on an actual cooling duct. Splashy!This design already beats out the vast majority of 3D printed compressor attempts in terms of "building boost without exploding", but performance is only half the battle -- can we make boost without screaming for it? The original version didn't manage it, but I kept pushing, starting by chasing even lower-RPM boost by stacking a second stage on the one I'd already built. I also updated the impeller with a new design that can be tuned and balanced. Between the lower RPMs and a new intake silencer, the only remaining source of obnoxious noise is my crappy low-frequency PWM motor driver (salvaged cordless drill) -- hopefully it'll be an easy fix to just run it off my printer's MKS MOSFET fan driver like I was planning to anyway!I am planning a more comprehensive design overview (covering subjects like "what on earth is a regenerative compressor, anyway?") and test result video in the near future, but I'm too excited not to post more snippets (shoot me) 😆Trihorn cooling duct STLs from the VzBot github: github.com/VzBoT3DYou can get STLs for the original version of this compressor here: printables.com/model/254316-regenerative-compressor-ring-blower-side-channel-bI'm also a writer!

COOLING POWERRRR brings out my EVIL LAUGH 😈 James Pray 2022-08-24 | Test firing a higher-powered blower made from a salvaged Shark dust buster and a home-rolled housing. 8.24.22 NOTE: this is an old post that was just unlisted, but I listed it since my catalog of compressor videos is growing anyway. The impeller is from a Shark SV780; the housing (intake stack, volute with gasket and screw-on seal, and nozzle with lock ring) is homebrew and unpublished. I've been using this blower for speedboating for a while, sometimes under the moniker "ubercooler", by controlling it with a generic MKS MOSFET board and a 12V power supply. The dust buster fed it 18V, and even at 12V it draws enough amps that a 12V 20A supply cannot start it and heat up a 12A bed simultaneously (I nearly had a heart attack when I found this out the hard way, but thank goodness it didn't actually blow up my PSU, just shut it off). It sounds like crap, or at least like a vacuum cleaner, but it gets the job done, and it only cost the PLA for the housing since I already had the dust buster. Even so, I'm developing a more fully-printed replacement, since it's pretty choked by my cooling setup, the current draw is really high, the sound IS a problem, it doesn't really run below 50%, and its motor really heats up the output air. I also found out in August 2022 that its stock smoothing capacitor was not well-suited for long-term low-PWM driving (I assume the source dust buster did not use PWM but was just on-off) because it exploded after 40 minutes at 60% and 3k hz PWM frequency. That's just part of the learning curve -- I had no idea what the cap was for and decided to leave well enough alone until something went wrong ... and it did, woo another heart attack! I'll replace it with some smaller ceramic caps and it should be good (it works without, too) ... but this is why I don't typically publish niche designs right away! That cap explosion was loud, scary, stinky, and who knows what it did to my cancer risk...
Printer diaries: No need to scream? | Shorts James Pray 2022-08-23 | UPDATE, UPCOMING PLANS: I'm going to get a proper 775 motor for this, update and replace the impeller (no more rubba-rubba-rubba), and do another round of testing with an actual PSI gauge and maybe even a tach. Stay tuned!... (Screamin' pressure test video: youtu.be/YhsYaHobx-4)Background: I had an exciting afternoon today as, after a 40-minute run at 60% PWM on cooling, my Shark dust buster ubercooler made a loud bang and a cloud of smoke while I was checking it for overheating. After that it ran a lot better, but I still had to take it out and figure out what happened because electronics don't generally let out the magic smoke and *then* work better. Turned out the smoothing cap exploded quite violently. ANYWAY, I took the chance to hook up the prototype 3D printed regenerative compressor that you might recall from the screamin' demon pressure test video and find out what % of unleashed hell it actually needs to do an equivalent job versus my normal, very quiet cooling solution. Turns out about 3-5% hell would be PLENTY for my day-to-day cooling needs 😮😮😮At this speed, if you discount the rubbing of the unbalanced impeller (which I will fix), basically all the noise is the motor whining unhappily on the low PWMs. If I can find a solid motor solution that's better sized for this RPM range, I think it could be near silent. I was bummed about the noise level on this thing (and yes, the sound in this video isn't pretty), but I'm excited about its potential again, now.Also, one big difference from the dust buster cooler is that the motor is external to the airflow, so it's not pumping heat into it.I think we might be on to something, here, after all...You can get STLs for this compressor here: printables.com/model/254316-regenerative-compressor-ring-blower-side-channel-b

3D Printed Regenerative Compressor (Supercharger) 25Amp Pressure Test James Pray 2022-08-06 | Regenerative compressors provide good pressure head and medium flow at low RPMs. I designed this 3D printed one from scratch in Sketchup to play with the concept for potential CPAP cooling on my printer. It starts to build pressure head at fairly low RPMs, but it needs plenty of power ... so after a lame smoke test with a 1 Amp DC motor from an inkjet printer, I decided to try out a 25-30 Amp cordless drill motor belted down by 3:1. Now THAT'S some BRRRRRRRR!*8.30.2022 CORRECTION/UPDATE: the highest pressure I have MEASURED on this unit is 0.75 PSI at around 7-8k RPMs (estimated) with the flow nearly stalled.I even posted the files this time, so if you want your own, head to printables.com/model/254316-regenerative-compressor-ring-blower-side-channel-bI genuinely think this regenerative direction might be a viable path for higher-head 3D printed air compressors. The efficiency even on commercial versions isn't awesome, BUT you can get usable pressure without needing 50-100k RPM like a small-diameter centrifugal compressor needs, meaning the stress on the plastic parts is MUCH lower and there's little/no risk of exploding wheels or suddenly friction welding force-expanded parts and blowing up the motor. The sound on this one is pretty awful (or awesome, in small bursts), but it really does start working at very low RPMs. You can actually feel it start to work even just spinning the shaft with your fingers. I think a multi-stage version might be able to build a lot of head without needing these jet engine-screaming RPMs (which aren't actually all that high -- I would guess only a few K tops). And even if this one does scream, you'd need real screamer of a centrifugal / turbo compressor to get the same boost, and 3D printed positive displacement pumps like roots blowers and screw compressors seem to sound universally awful ... blah blah blah, but yeah, I'd have to figure out the noise issue before putting this to any daily printing use.I will probably explore this direction further in the future, maybe with a proper brushless motor, and maybe even get a real pressure dial and a tach to quantify results! I may also play with printed intake/exhaust silencers, which some commercial versions use for reasons that are much more obvious after these tests (ha).

3D Printed Regenerative Compressor 1 Amp Smoke Test James Pray 2022-08-05 | Playing around with power sources for a new 3D printed compressor design with potential application for cooling via CPAP hose. This one is a regenerative compressor, sometimes called a side channel or ring compressor or blower. They're meant for high head rather than high flow, and what interests me is that they don't need high RPMs to do it. Turns out they do need a fair bit of power, though, which is probably why all the commercial ones have big honking motors on them 😆This is into what I'd call the "usable" range with this 1-amp-ish motor driving it somewhere in the low 1k RPMs. It feels as strong or stronger than my current "daily driver" remote cooler. Hopefully, though, I'll be able to test some beefier candidates ...
Im Scared of My Part Cooling James Pray 2022-07-29 | I tried going full Dexter on RocketKossel so I could do the water test with my custom high-powered part cooler.I knew there was a reason I hadn't tried this before 😑Is it CPAP? CPAP hose, yes! CPAP blower, no! If the sound wasn't a clue, it's a salvaged Shark dust buster impeller -- and it's actually undervolted right now, being rated for 18V. I drive it off an MKS MOSFET board using the FAN2 pins on my Duet2 Wifi. Simple, effective, and much cheaper than a "real" CPAP blower!Check out my designs at:printables.com/social/237889-kiolia/modelsI'm also a writer!

Hurray, it still works James Pray 2022-07-12 | Nothing special here, just a quiet benchy to test the latest upgrade: a change to 9C linear bearings from 12H, which let me drop almost 100g of moving mass. Ideally I'll be swapping to a 24V power supply shortly, and then we're back to more good times with the ugly boat race :P
Rigid flying BondTech LGX Motion Test on Kossel Delta 3D Printer James Pray 2022-07-08 | RocketKossel evolution continues! Motion testing a new flying gantry design iteration for my BondTech LGX. This replaces one full-motion joint on each damper with a vertical pivot. The result is that the extruder's position, orientation, and Z height is set by the carriages, rather than by the effector pulling on the bowden tube. The motion tests show that this keeps the bowden length consistent and pointed toward the effector. Hurray!I wanted to explore this direction because the extruder didn't seem very well decoupled from the effector before, and the previous design put a lot of tension on the bowden tube, creating sharp bends and high friction on the filament at some positions. This new design leaves some slack in the bowden for easier and more consistent extrusion throughout the build volume. Time will tell if it's reliable, but earlier results show solid improvements in certain ringing artifacts and in PA values needed for nice seams.Check out my designs at:printables.com/social/237889-kiolia/modelsI'm also a writer!

#SpeedBoatRace 9:24 Benchy on Kossel Delta with Pico, LGX, Duet2 ... and a Shark Dust Buster? James Pray 2022-02-20 | RocketKossel delivers! If you can't guess from the video, this one came at the end of a looong afternoon and almost a dozen disappointing speedboats in a row. I'm confident that this time I've found my machine's bleeding edge and left nothing major on the table without more upgrades. It's a heckuva lot faster than I thought I could go in PLA on 0.9 degree steppers at 12V!I was pretty sure the 12:21 run was near the limit, before, so what did I change? First, I spent a LOT of time dialing in the slicer settings and testing (and testing and testing) until it *just* stopped layer shifting. I added 5C to the extrusion temp, and switched out the PTFE-lined, PLA-friendly nozzle for an all-metal one (in hopes its meltzone might be functionally longer). Also, two hardware improvements: I developed a new home-rolled RTV silicone sock, the "KapWaffle", that insulates that lil' Metaform Pico a lot better under high wind conditions; and I swapped out my usual layer cooling system for a salvaged dust buster impeller in a home-rolled mount/enclosure/volute, which is powered by a separate 12V supply through an MKS MOSFET board and controlled by the Duet2 through the second PWM fan output. The new cooler is actually so powerful that I had to dial it back to 68% for this print, up to 72% for layers under 2 seconds -- any more and the layers just fell apart! It's stupid loud, so I'm taking it off again until the next time I get the urge for some speedboating...Speedboat biz:Time 9:24:06Sliced per speedboat rules, .4mm nozzle and .4mm line width, .25mm layers, 10% infill in 0.5mm layers, 2 perimeters, 3 top/bottom layers.Hatchbox black PLA, 225C on 60C bed.Sliced in Cura 4.12.0140mm/s Infill and 190mm/s Walls/Top/Bottom/Travels at 33k x 40 jerk for all except Travels at 32k x 25 jerk, 150 x 20k x 40 initial layer speed with 200 x 20k x 40 Travels for some reason.Main printer specs:12V 550W ATX power supply (main) + 12V 20A AnyCubic power supply for coolingBondtech LGX Extruder (flying)Metaform Pico Hybrid hot end + custom KapWaffle sockSeeMeCNC aluminum barbells + Trick Laser ArmsWantai 0.9 steppers (42BYGHM810)Duet2 Wifi running RRF 2.05Capricorn bowdenAnycubic Linear Kossel XL extrusions, rails, and bedRobotDigg aluminum cornersROCKETKOSSEL printed frame bracing, moving parts, etc. (mine, unreleased) with 77 gram effector and remote coolingSalvaged Shark SV780 dust buster impeller + MKS MOSFET for layer coolingVision Miner NanoPolymer bed adhesiveCheck out my designs at:thingiverse.com/kiolia/designscults3d.com/en/users/kioliaI'm also a writer!

Failboat: hilarious self-destruct edition | Shorts James Pray 2022-02-18 | Did you ever have a print go so wrong that you couldn't stop watching to cancel it? Yeah. This fail's worth the wait, I promise!Working toward an actual 10-minute benchy. Just not quiiite there yet. You have to botch a few (/bunch) of boats to make an omelette, er, fast boat.
Failboat olol | Shorts James Pray 2022-02-08 | Gunning for 10 minutes, but more cooling does not a faster speedboat make ... yet. I salvaged a dust buster impeller for supercooling, but it's sort of like a leafblower and hard to apply without faulting the heater. Also, the motion system's pretty happy swinging 22.5+k on 12V, but the extruder says NORP, and we've got to find a way to get more cooling air to the part without ripping the heat out of the hot end. I think I'm done speedboating until I get around to replacing my power supply.General slicing settings were 225mm/s x 22500 mm/s^2 x 40 Jerk, 60 Jerk for walls, travels at 250 x 25000, PLA at 220C.
3dBenchy Raw & Uncut - 12:21 with Pico and LGX | Kossel Delta 3d Printer James Pray 2022-02-01 | Now we're cooking with gas! Is this the fastest benchy printed on a 12V printer? (Spoiler: nope!) Comment if you know a faster time, or just tell me I'm a dummy for not changing power supplies sooner! And yes, it really is that quiet.Just how far will weight reduction take a printer's performance? I realized that with my new 77 gram effector and brand-spankin' new Pico Hybrid, I could be swinging waaay more acceleration, so I sliced a fresh benchy per speedboat rules at 200mm/s + 15k mm/s^2 + 30 jerk all around (except travels at 250 x 20k), turned off pressure advance and retracts to give the LGX a fighting chance at 12V acceleration limits, and let 'er rip. I'm thinking of calling this build the RocketKossel. Hey? Hey?Can we beat 10 minutes without more upgrades? I'm really not sure. 12 minutes is a lot faster than my last post at 20, but 10 is a lot faster than 12. It's all a game of chasing weak links, and now that my frame, extruder, and hot end are running so well together, we're back to layer cooling falling behind -- plus the power supply, but we knew that. Next stop, 48V, I think, when I can pony up the get'r'done to swap out board, power supply, fans, ugh...Main printer specs:12V 550W ATX power supply 🤢Bondtech LGX Extruder (flying) 🤩Metaform Pico Hybrid hot end 🥰SeeMeCNC aluminum barbells + Trick Laser ArmsWantai 0.9 steppers (42BYGHM810) 🔥Duet2 Wifi running RRF 2.05Capricorn bowdenAnycubic Linear Kossel XL extrusions, rails, and bedRobotDigg aluminum cornersROCKETKOSSEL printed frame bracing, moving parts, etc. (mine, unreleased) with 77 gram effector and remote coolingCheck out my designs at:thingiverse.com/kiolia/designscults3d.com/en/users/kioliaI'm also a writer!

3dBenchy Raw & Uncut - Pico Hybrid helping me break 20 Mins | Delta 3d Printer James Pray 2022-01-16 | Hey, another raw 3D Benchy print run because I've got a new hot end to put through its paces -- the Metaform Pico Hybrid! No affiliation with Metaform, but I'm extremely impressed with this thing so far and I hope they sell a lot of them. It's a tiny high-flow monster -- and beyond that, a pretty painless switch from the E3D V6 I was running before, in terms of setup and configuration. Apart from a new effector to mount it in, all it took was a PID tune to get going (though I'll be fine-tuning plenty more, of course!). Total print time was 19:49. At this speed, I'm probably close to the limits of my 0.9 degree steppers until I upgrade from 12V, but compared to the last time I shot for a sub-20 benchy, this sure was drama-free (and QUIET)! Sliced per speedboat rules at 210C PLA on a highly modded Kossel, blah blah who cares if it ain't 4 minutes 🤣Check out my designs at:thingiverse.com/kiolia/designscults3d.com/en/users/kioliaI'm also a writer!

Unscripted Rambling | Mocking up a BONDTECH LGX Extruder in Sketchup | Modelling Real Things James Pray 2021-05-28 | Another unedited ramble about Sketchup 2016/2017, this time covering my approach for modeling real-world items to be designed around for 3D Printed parts. In this case I need a model of a Bondtech LGX (Large Gear Extruder) so I can adapt my existing flying extruder design to use it on my Kossel 3D printer. Sketchup can't directly import a STEP file (which Bondtech provides), so it's time for the next-best thing -- modelling my own, with a focus on hitting the critical dimensions and not worrying about incidental detail....Just kidding, I worry a lot about incidental detail in this one, which is why it's an hour long. If you're new to modelling in Sketchup, though, especially if you want to design for 3D printing, this might give you some good ideas for working more efficiently, and I had some opportunities to demonstrate how to quickly deal with some of Sketchup's minor quirks.Check out my designs at:thingiverse.com/kiolia/designscults3d.com/en/users/kioliaI'm also a writer!

3dBenchy Raw & Uncut - Chasing sub-20min - High-Speed Delta 3D Printing (Linear Kossel) James Pray 2021-03-16 | Great success or dismal failure? YOU DECIDE! Trying to break 20 minutes on a 3DBenchy print by setting everything in the slicer to STUPID (ha). I thought it might be in reach now that I've finally replaced my printer's original V5 clone for an E3D V6, and I'm pretty sure it is. Sadly, bed adhesion failed me this time ... and the test broke a few frame parts. But BAH I say - they needed replacing anyway!I don't remember the exact slicing settings, but they were in the neighborhood of 200+mm/s and 5k+ mm/s^2 for most settings, .25mm layer height, 10% infill, 2 perimeters, all in line with the 3DBenchy challenge parameters. I usually use pressure advance but it slows down printing, so not this time!Printer main details: * Anycubic Linear Kossel frame, steppers, rails, belts, and endstops * Trick Laser 300mm CF ball cup arms * SeeMeCNC aluminum barbells + white lightning bicycle chain lube * Duet2 Wifi 32-Bit controller * E3D V6 * Nimble V1 + custom 3:1 belt overdrive for 10:1 ratio overall * Custom effector and carriages * Custom frame corner and wire cable bracing * Custom 120mm compressors for hot end and layer cooling * 520W Corsair ATX power supply * Top-mount spool on hard drive bearing * Heated glass bed + salt haze for adhesion (clearly not perfect)Check out my designs at:thingiverse.com/kiolia/designscults3d.com/en/users/kioliaI'm also a writer!
