Are you removing U2 as well? If you do, you'll need to power the pololus with 3.3v instead of 5v for the control side.Beutrocks wrote:Hi I am finishing up board probably be done by tomorrow night I am going to leave everything but inputs. Just to check myself I would just not connect those pins to that. Also would I just pull off U3 in order to remove outputs as I don't need them either.
Thanks and about how many holding oz-in are your steppers I think I will get the weak ones because I am only trying to mill small wood projects and pcb so I dont think I would need strong steppers.

The instructions posted in the wiki should work fine on ubuntu.Beutrocks wrote:Can you explain to me what to do on ubuntu or linux to compile the kernel thanks.

Hello Thomas,hybris wrote:hey kinsa
Sorry for the dumb questions, i just want to know if i got it right:
With your image you send the position commands via the gpio pins to the pic nc (jr).
The pic on it translate the position commands to a digital signal for the pololu driver, which sends
the sequence for the stepper motors. Is that correct?
Thanks a lot!
