I am having a hard time finding configuration files for Marlin for the Printrboard Rev F. Most Of it I looked up myself, but I cannot find out how to enable the digipots for motor current control.
And no, i’m not looking to run printrbots marlin branch unless I absolutely need to.
The only thing I see Marlin handling with pots is the DIGIPOTSS_PIN. I’d look at printrboard’s Marlin and see what they define that and DIGIPOT_CHANNELS to.
If I’m understanding what you’re looking for correctly, the current control on the Rev F (and the rest of the Rev F source files) is on their branch in a special header and source file that handles the MCP4728: https://github.com/Printrbot/Marlin/tree/revf-metal-simple/Marlin
I see two different rev F branches, how do you know which one is correct?
Well, that one worked. I’ll need to see if I can hack in the mcp4728 into the main branch, or maybe someone has already done it. The board would be compatible if it wasn’t for that one part. So annoying.
It took me some time to find the right tree on github, you are not alone.
