Here you go...
You would think if it was a HAL issue that I wouldn't get accurate reporting of my movements on X & Y.

Not sure this will make any difference but try commenting out these lines in your hal.
net x-vel-cmd => pid.x.command-deriv
net y-vel-cmd => pid.y.command-deriv
net z-vel-cmd => pid.z.command-derivPlease Log in or Create an account to join the conversation.

Damn I forgot about that ...PNCConfig does that automatically so we should submit a but request to fix that. I was using stock PNCConfig files.
That solved my issue. I was able to tune my servos now. Thank you!

Todd I saw you helped someone else with a toggle button issue but mine was slightly different from their request. I would like to add a toggle button option on my gamepad to turn my amp ON/OFF for my Z axis.
So here's the entry in my hal:
# --- Z-ENABLE ---
setp hm2_7i43.0.gpio.040.is_output true
net z-enable hm2_7i43.0.gpio.040.out
Then I saw the help file for wiki.linuxcnc.org/cgi-bin/wiki.pl?One_Button_Toggle
I am thinking that I need to do something like this in my posgui.hal file:
loadrt toggle count=1
addf toggle.0 servo-thread
net toggle.0.out => z-enable
net z-enable toggle.0.out <= input.0.btn-base4 #Button on joystick
I think the physical connection I need to put my 2 wires on are it's I/O 18 on TB1 bus. This is just to open and close the switch for that amplifier.
Can you tell me if I'm off in outer space or pretty close with what I think I need to do?
