Firmware, 5i25 was created by Tesremos
Okay, so todays project is connecting a little home mill to a 5I25, With a china Abob (one of those generic 5axis parallel port bobs that are very common) and on the second header, 4encoders.


the question, is there firmware for this already? if so, can someone point me at the file name? please.

second question, is in pnconf, is there a way to have pnconf list all of the encoders? or do i have tommanually hand code them after setting the stepgen allocations?


Thank you in advance for any worda of wisdom.
