Mesa 5i25/7i76. Looking for some help.
When I have them hooked up to the Mesa 7i76 I can see that the Z axis motor's measured speed is about 1/10 that of the X axis.
Teknic thinks it's the controller causing this behavior. I'm going to complete the PncConf wizard for now. Who knows maybe it's only an issue when I'm in the PncConf mode.
Yes, they are same exact model. I had swapped them before and just tried again, the slow one always spin slower than the fast one no matter which axis I plugged it into. So I'm suspecting it has something to do with the motor, its internal firmware or something along those lines.
If this is true, this is a a motor/driver setup issue unrelated to LinuxCNC or the 7I76/5I25
In the Axis GUI I first tried the home all function. The lathe started moving in Z- direction (towards the spindle) where I think it should be going the other way towards the switch. So I opened up my .ini file and added a minus sign in front of home search velocity to correct this. It works but then it never gets close enough to trip the Z switch. After a few more tries I get these error messages saying joint 0 and 2 on limit switch error. I played around some more and now got my X axis travel maxed out at one end (away from the X switch). Trying to make it go back it says Can't jog point 0 further past max hard limit. Not sure how to get my lathe out of this but none of the 2 switches were ever tripped and it won't allow me to manually jog it anymore lol.
It has always worked for me.
I monitored the Z coordinate position display while it tries to home and can tell that the ClearPath was moving much much slower than what the coordinate number was displaying. I think this is what caused the error because Linuxcnc thinks the machine has now crashed because it exceeded the soft/hard limit when the motor has not actually moved that far yet to trip it. So to be safe it won't let me jog or turn the machine on.
Sorry I can't help further. I'm assuming the clearpaths are their "stepper killer" which look like a conventional stepper to LinuxCNC as I've never used servos.
