For a long time 3D printers relied on bed springs in each corner to level the bed and ensure a good first layer. However, most modern designs do away with them entirely. So can we safely remove them and rigidly mount the bed? In this video, I examine a range of 3D printers with and without springs to try and find an answer. I then do a before and after comparison on the Ender 3 with print tests.

![Modular docking bar - Budget Sovol SV08 toolchanger part 4
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
I own a five tool Prusa XL, which is now working pretty well. For many people though, this 3D printer is just too expensive. In this series, we are attempting to take a StealthChanger toolchanger mod intended for the Voron 2.4, and adapt it to the Sovol SV08 Voron clone. In this episode, we complete what I hope is the final wiring to the six tools (but maybe not), and build a modular dock to hold the idle SV08 tools.
This printer and the additional toolheads were received free of charge from Sovol for the purposes of making this series. Everything else I’ve paid for myself.

Layer shifts are so annoying and will ruin any 3D print. In this video, I explain what a layer shift is, and categorise the three types that can occur. Each version is then given a detailed list of things to check or change to avoid the problem.
Please share your tips in the comment section to help others.

Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
I don’t like waste, so I don’t want to throw away obsolete parts with previously installed heat inserts. In this video, I show you the technique I’m currently using, and invite feedback and suggestions for better ways. I don’t want to buy any specific tools, so keep that in mind. I’m looking forward to some good feedback.

![Everything went wrong but I still designed this custom articulated storage box
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
I needed a custom storage box with some trick articulation, but the universe wanted to fight me every step of the way. I got there in the end, and levelled up with my design skills. This is that story.
A summary of the curse:
Plywood changed composition and would not cut cleanly
Laser cutter belt became loose and then detached
Repair of laser cutter was stupidly awkward
New problems introduced after repair which needed calibration
Laser cutter not square
Power outage once everything was actually working
3D printer decides to randomly reset for the first time, mid print
2nd choice 3D printer decides PETG will not stick no matter what
Rain on the day I wanted to paint
Broken blade trying to shorten a screw
Rain now that I’m done
While I was filming the last shot, my dog stole a new pillow and ripped it to shreds

![3D printing + CNC milling - Worth the effort?
3D printing is accessible, but has its drawbacks. CNC milling for most is harder to set up, butoffers great precision at the cost of inefficient and wasteful subtractive manufacturing. What if we 3D print an oversized model, and then mill it down to the final shape, eliminating layer lines and other imperfections? In this video I experiment with this concept on an F1 in Schools wheel.
I think everything was a win apart from the surface finish. More experimentation with spindle rpm, feed rate and cutting depth could yield better results. Also me having more patience with sanding and polishing at the end would surely help too.
Is this all just a waste of time or are there suitable applications?

![The 5 tool Prusa XL is currently flawed, but I think it can be fixed
Check out my 2nd channel, TT Racing: https://www.youtube.com/@ttracingYT
A QUICK UPDATE video using non alpha firmware: https://youtu.be/bVY3S22L4EY
2nd update: Prusa have released a new version of the slicer with some counter measures for the blobbing and stringing. I will keep testing and update in a future video.
It’s been delayed for some time and the price hasn’t gotten any cheaper, but finally my 5 tool Prusa XL has arrived. Was it worth the wait? So far, the printer is quite undercooked. In this video I take you through my honest experience, including the problems myself and other owners are facing, as well as some of my intended fixes. Hopefully Prusa can release some updates to get this machine working as it should.
My apologies for my ranting in this video, but honestly I could have added more. Things like needing to turn down the crash sensitivity to stop false positives, the nozzle dragging across the bed after purging and leaving trails, the fact that you can’t adjust things like acceleration from the printer settings, the friction from the long ptfe tubes making it impossible to load tpu without pulling bits off, the PTFE tubes rubbing on the metal frame behind the tool posts, the USB flash drive being fussy with insertion angle.. The whole thing is just underwhelming.
This video is dedicated to my two dogs, Ricciardo and Sofia, who were both tragically killed by snake bite this week. Treasure your time with loved ones and pets, because you never know how long you will have with them.
