While I had been slowly but steadily improving the mechanics of the printer, adding dual extruders, et al; I had ignored the electronics till now. I was still printing through the RAMPS + Arduino Mega that Cobblebot had provided. I had been thinking of upgrading to a 32-bit board and had done some preliminary research – narrowing down to a Smoothieware based system. While the documentation on the Smoothieware wiki is great, there was no step-by-step document that detailed out how to upgrade from Marlin / Repetier to Smoothieware; there was no way to find out which settings were to be transposed where. So.. here it is.
I also did some rudimentary testing pre- and post- upgrade to compare and see if the move is even worth it. TLDR – It is most definitely worth it.
The following is the current configuration:
- Cobblebot Basic (heavily modified)
- Printable Area: ~15”x15”x15”
- Based on Wheels on V-Slot
- Moving Bed
- XY on top rails
- 2 X belts running from a smooth rod
- Dual Z motors (wired in series)
- Glass bed on 3 spring supports for leveling
- RAMPS (Chinese) with Arduino Mega (Supposedly Original)
- DRV8825 Stepper drivers
- Chimera Clone with dual Volcano Nozzles (multiple nozzles ranging from 0.4mm to 1.2mm)
- Running off a Rapberry Pi Zero with OctoPi
As I mentioned, I was among the lucky ones and was able to print from the kit, and had achieved good quality prints after all my modifications. However, I think I like to tinker with my printer, more than actually print with it
One of the few things that remained from the original kit was the electronics; and I had been thinking of upgrading to a 32-bit controller. Why? Just Because…
I chose to go with the Smoothieware based boards.
