How does the change in Fusion 360 licensing affect the current software chain?
YOu may have already read through this, but here is Autodesk's article:
My understanding is that everything needed for ASMBL will be unaffected by the changes.
The functionality necessary for ASMBL are: 2.5 and 3-axis milling, additive slicing, and the ASMBL add-in script, all of which will remain available to the personal license.
BTW, I finished my first Orbiter extruder using the modified housing to handle the wiring and a modified drive train so that all of the parts except for the extruder/hobb gears and fasteners can be printed in Nylon CF. The modified spider/drive shaft and gears don't use the three smaller ball bearings, they are press fit and PTFE grease lubricated nylon on nylon. I think the milled aluminum spider/drive shaft, ball bearings and printed spur and ring gears is probably the better setup, but so far, this is both lightweight and working.
I also have the Duet3d firmware set up for 4 micro-steps per 1.8 degree step and at 1600 mA (it's spec'ed at 1800) so that the Wantai stepper motor can extrude up to about 15mm/s for any reasonable length of filament (not print speed but 1.75mm filament consumption speed). If I did the math correctly, it roughly equates to moving a 0.4mm nozzle at around 240 mm/s. It will extrude short amounts of filament much faster.
I am still testing to see if it extruder consistently or not. If not, it probably means that the drive shaft should be made out of a stiffer material and maybe that 3d printing it myself will not result in something precise enough to work really well.
Have you tried milling Nylon CF yet?
Might slow milling operations slightly as 'rapids' are no longer available and travel cannot be faster than milling moves.
Awesome! I'm curious to see how all the Nylon parts wear together and thanks for your firmware settings. I took my orbiter off the printer because my printed igus gears started to crack. It never failed but I didn't want to ruin a print!
I haven't tried milling CF-Nylon, but E3D has some notes about CF-Filament here: https://github.com/AndyEveritt/ASMBL/blob/master/docs/usage/materials.md
Maybe in the future!
