Bas, Thanks for the much more recent config file links. There's a bunch of configurations on your github list, which would be the best to try? Any recommendations on changes needed for a BeBoPr++ config to work with CRAMPS? Again, many thanks. On Monday, September 26, 2016 at 4:59:50 PM UTC-4,

OK, again, making progress. Using the Ilaro config files, I changed the dimensions to my printer's, and fixed the step timings for the Alegro stepper controllers I'm usng. The quandry I had about motion direction appears to be understandable by me now. I was looking at the cartesian coordinates

I apologize for my stream of consciousness posting, but I'm running out of time for Makerfaire in four days. I was hoping to get this configured and printing in time for the show, but I'm not sure I can make it happen. This Machinekit interface is very difficult to get going for linear delta F

can i use a normal resistor to get 3.3v out of 5v or do i have to use a step down voltage regulator, that outputs 3.3v and works with 4v? (when it is a constant voltage of 5v, i could use a regulator but i dont know what to use for signal because it is a frequency, not a constant) in case of a

Why do you need a 3.3V regulator? The BBB supplies 3.3V which probably has enough current capacity to drive whatever I/O circuits you need to hook up. If you are referring to the eQEP0 inputs signals, if your encoder provides 5V signals (likely) you just need to make sure they never go above 3.3V

Hello Sander, I know some time has past, but I only recently found out about your father's passing, and I send my condolences. I do not know if you found someone to purchase the untested boards, and if not, I would be willing to discuss this further. Regards Ken McNabb On Thursday, January 7
