@dbemowsk Thanks for the shielding material tip, I may buy it later if starting to work with 0.5w 405nm laser for engraving. (Some safe enclosure definetly needed)
In the meantime I have not constructed my CNC 2418 from Jack's store and tested that I can control it by seding the g-gode commands from terminal. I have not yet tried to workflow from Kicad, to flatcam and from there to bCNC.
Original GRBL firmware was 0.9j but I managed to upgrade it to v1.1h over USP without need for using another arduino as a ISP programmer and wiring it to woodpecker. Arduino-ide did not detect the board automatically but the flashing to grbl 1.1h worked with a following command out of the box on my linux by using a following avrdude command:
avrdude -v -C/etc/avrdude/avrdude.conf -pm328p -carduino -P /dev/ttyUSB0 -D -Uflash:w:grbl_v1.1h.20190825.hex
This thread is so long that it takes lot of time to try to find all important steps. But what I have gathered is that 3 most important things that I am still missing before trying to mill are the
-
auto leveling
What I read, this should be easy with gBNC. Mostly connect one wire from the drilling bit to A5 pin in woodpecker and another from woodpecker's ground to pcb. -
Current adjustment for all three A4988 motors.
If I understood correctly @andrew and @NeverDie both changed that from 0.6A to 0.9A? Can that be done only by rotating the potentiometer on a4988 driver boards or do I also need to add some resistors? -
End stops modules? Could them be connected somehow to woodpecker?
