X axis issue 7I96s was created by Streng123
Hello,
This is my first time using Linux cnc as well as a mesa board. I have a plasma table I built that i'm upgrading from an arduino. I'm using open loop stepper motors. When i set up my mesa 7I96s using pncconf i get my y and z axis to run great, my x does not. If i call my x axis Y, it will run just like it should. When I tell the config it is controlling the x axis, the motor does not run smooth and when coming to a stop it goes back the other way and then shudders. I'm lost as to whats happening. Does anyone have experience with this issue?

I don't see anything obvious different about X but if you have poor network latency
(as suggested by the 1.5 ms servo thread period) you might try changing:
setp hm2_7i96s.0.dpll.01.timer-us -50
to:
setp hm2_7i96s.0.dpll.01.timer-us -200

Well i finally had time to get after it this weekend. I had my boot usb in the back of my pc so i was resetting it up every restart. removed that and did another set up. after a bit of tuning its running like a champ in all axis. I did change the timer and it seems like some of the other errors i was having went away as well.
Thanks for all the help!
onto the next roadblock..
