Guidance Needed! Initial LinuxCNC/PncConf setup

I have finished the electrical cabinet and have connected the LCNC computer to the Mesa 7i76E and they are communicating. 

My configuration:
Debian Bookworm
LCNC 2.9
Mesa 7i76e
X&Y Stepper Motors - Nema 24
Z Stepper Motor - Nema 23
Digital Stepper Driver - DM860T
Axis (3 axis) configuration - XYYZ (I only have limit switches on one of the Y axis's)

I am trying to do the initial setup in PncConf but am having trouble understanding some of the settings. When I try to Test/Tune Axis I get no movement at all. Here are my pncconf settings.

 
 
 
 
 
 
 

When I click Run on the X Axis Tune window I see the Hal Meter windows running but nothing at the motors.

Also when I turn the PS for the drivers/motors on the motors have resistance (holding power). If I try hard enough I can turn them but not as easy as when PS is off. I assume this means that the motors are wired correctly?

Could use some guidance.
Thanks

 

I suspect the step/dir timings are off. The Pncconf default timings are fairly high and should work. 
Leave the "drive enable" pins unconnected. Drive is enabled by default

Try these settings

DIRSETUP = 15000
DIRHOLD = 10000
STEPLEN = 5000
STEPSPACE = 5000

Next, try some of these timings here:

Hey thanks for that. I actually saw some movement.

But it seems hit and miss. Some times when I go into the Test/Tune Axis screens I can get the axis to move using the +/- buttons on the Tune window. Other times the motor will not do anything. Even if I close the test windows and then go back in they will not work. Sometimes if I go back and to the Mesa card Configuration Page and Accept Component Changes and then go into the Test screens it may work or may not. Sometimes when I press the Run button it will cycle back and forth non-stop and other times it will just stop and I cannot get it to start again. Very inconsistent.

I have been messing with the timings but have not figured out why the inconsistencies.

Any ideas?

I followed your instructions but I am not sure what it is supposed to do. I opened the file and it loaded. I went to machine>calibration and was able to see the settings. I was also able to save the file but I am not sure how to get it to move. Nothing seems to work.

When in the Calibration>Test environment the amber light is on on the Mesa board as it was when the motors would stop in pncconf. So nothing would move. Being new to LCNC I am kind of lost on how to manually move the axis's around.

I have also read about how in order for the two Y axis motors to work together I need to set Home. When in pncconf and testing the Y axis, only one motor turned. Any help on setting Home would be appreciated.

Thanks!

Now that I have fixed the error, can someone help me figure out how to manually move/test/fine tune my axis's?

I have loaded the config file I created in PncConf but am not sure what to do now.

Thanks

I cannot for the life of me find how to do the initial Homing of my axes. Everything seems to be locked until I can set Home for all axes. I have read through all the documentation I can find but it all seems very complicated and does not really show how to do it.

Is there a step by step tutorial or something?

I don't see a Y limit switch input, only an X, Z, and Y2.

I would think you need both Y and Y2 to square the axis.
