Hey all,
It's been an awful long time since I hang out here (more than 10y) but I would like to consult the incredible hive mind here again. I'm currently working with Product Development students on a modular flexible open source 3d clay printer. Most stuff is easy to settle on except the electronics. We would like to make the machine compatible with two options:
-A high end option using Duet and RepRap Firmware (RRF), this because it is the most used board in commercial ceramic 3d printers like the Lutum, Potterbot or Stoneflower and a favourite amongst DIY enthousiasts in the ceramic 3d printing community. It's open source, well supported and has shown to be viable as a long term controller choice (so no question here honestly).
-A low end option, especially to drive cost down and make it accessible in the less wealthy regions of the world where there's a lot of demand. 5 years ago the choice would be easy with an Arduino + Ramps. But today I'm not sure anymore what is the best default low-end option. Ramps & 8-bit seem to be on the way out? These days lot's of 32bit boards seem to be around but I also see a tons of boards from Asia that seem to have a large diversity of dimensions and layouts. There doesn't seem to be anything that develops stably on a single dimensional footprint or pin layout?
The requirements for a clay printer(and so an OS one) are fairly basic:
-Delta machine 3 motor axises (so 8 bit sometimes a limitation)
-2 extruders (some clay extruders combine 2 stepper motors, one on supply and one in extruder)
-no heated bed or hot end requirements so low power consumption
-easely available around the globe!
-long term option, hopefully around for 5+ years or drop-in upgrades (same footprint, layout etc)
-no need for incredible speed or super high resolution or other fancy features (1-3mm nozzle typically, 0.5-1mm layer height)
related obviously is the firmware. For the high end it will be RRF, would be fantastic if there's a cheap board that also supports it but options there seem limited. Am I correct that the BTT SKR3 supports RRF? I also found this port:
[teamgloomy.github.io]
Not sure how stable that is long term.
Alternative would be good old Marlin (2?) with the disadvantage of supporting 2 firmwares...
Looking forward to your input!
