New Mill Build...Can I use LinuxCNC?

If I’m not mistaken this seems like a servo setting...I am not using servos, I am using stepper motors. Thanks, Andy

Just edit your ini file by hand as Peter said. Its still applicable for steppers.

Is the scale right as well I thought I saw some numbers around 8000 or so

Ok I know this has to be a stupid question but here goes anyways lol...I am opening the ini in Vim and I can find the p value and I am changing it from 10000 to 1000...then how do I save the changes? If I just exit out of Vim when I reopen the ini to double check it, it’s right back to 10000. I am completely new to Linux sorry for the incompetence. Thanks, Andy

There is probably an easier to use editor on your system, either mousepad
or gedit

Any particular reason you use vim?
I prefer to use "Text Editor" to edit the files. It's nice and simple and works great.

[edit]
Or the ones suggested by PCW.

to use Geany or Gedit would be easier

Ok great that’s what I will do...I just used Vim because that was the default program it opened with...simpler and easier sounds great lol...thanks, Andy

PCW that was the problem! ...now to figure out a optimized driver timing...am I correct that the lower you can set these timing numbers, As long as the steppers still function, the faster the machine can move?...I set everything back to the default settings as far as driver timing. When continuous jogging anything over 40 in/m the steppers start losing steps. What is a respectable speed? I realize that the mechanics of the machine will play a role into the speed, just trying to get an idea of what to expect. Thanks so much, Andy

It all depends.... If the pulses are too short, they won't be seen, if they are too long they will limit maximum stepgen frequency. I looked at it based on the motor RPM.
With An Arduino, I could not get over about 400 rpm
With a Mesa I could get to about 800 rpm. I think I settled on about 750 rpm as being the rapid speed. Thats a number you can reconcile with torque charts.
I played with the stepgen frequency by altering the microstepping and eventually Linuxcc reported an error saying it could not honour that frequency. I settled on 20x microstepping using Longs Motor DM542A and 48v power supply.
I still use 20x with the Lam drivers I am using but I will be seeing if I can increase the microstepping one day. These high quality drives should go a lot further.
