Was having issues with infill making diagonal lines. Got it sorted it seems @ 600mms, 50K.
Video stated .45 extrusion multiplier, but meant .945 @ 70mms. print is ranging here from .945EM to 1.0 based on speed(40-600mms) @ 50K.
Machine specs: BTT Octopus Pro 1.1 w-H723 running 48V. 320x300x380 print volume using HIWIN MGN12H rails for cross and crappy, but good enough, rails for the frame top. Filament is fed from a heated dry box and part cooling is a WS7040 CPAP blower using a 19mm hose.
Chube, Goliath, or mosquito hotend- currently Chube
Chube w 120W heater and silicone ceramic sock. Titanium lower shield(original was stainless steel)
- Insulation Heat Shielded Fire Thermo Armor Fire Sleeve Silicone Coated Fiberglass Heat Protection for Automotive Hose Lines & Electrical Wiring-（Red .75" ID x5FT）- you can use 1" or .75 may fit.
0.4 Tungsten Carbide nozzle, Sunlu ABS @ 285C. Pressure advance 0.002, smooth time 0.01.
LDO 2504 motors @ 2.5A, Z drive is belted @ 4:1 ratio with a constant rate spring as a counterweight in the rear drive only. Zero bed drift at power off. 1PZ bed system(all Z constraints are in the rear drive, front only lifts the bed and is not constrained to the bed.
Custom, 1 off, belt tensioning system built into the gantry blocks using GT3 Gates belts at registration spec of 28.5lbs. All double shear bearings and motors.
