I have had this little board for prob. 6 months. I finally got around to installing the software on it. It is pretty neat.
It is this board:
I think Bart is doing very small batches and you have to ping him about it on slack. IIRC, it was assembled for about $35.
I installed some fysetc tmc2130 v1.2s and I only had to remove the stallguard pins to make it fit. I enabled corexy and changed the home order. Then I set the cpu map. There is an error in the cpu_map for the x limit switch, but I bet that will get fixed soon.
Now, this board has some neat advantages for the ZXY.
- quiet driving (tmc2130s)
- Small footprint. It fits in between the motors
- Power, SD card, and USB are all on one side. So you could potentially build that into the side of your table and still protect the electronics from.tiny fingers.
- Web interface for loading gcode, and basic stuff like homing, movement, configuration.
- grbl, which is good and bad. Good because there is a lot less to configure. Bad because it starts in alarm until you home and it doesn’t recognize homing commands in gcode.
