so i went through the cleaning and the dianosis again found on this page (LS-THC Arc Voltage Troubleshooting Guide) , where you run voltage tests probing the VIM and the leads from the machine, all were within the required voltage.
then when i got to section C1, where it says to test the jogging speed , itll recognize the Y axis but remains at 0 for the x axis and Z axis.
section C2, REF and GND voltage test, im getting 4.12V DC
section C3, zero volts or mV
now that i got to C4, my firecontrol no longer shows a connection to the height control… fantastic …
