On the HP Servo panel there are LED's that indicate state of limit switches - so you can see if the problem is in the switch or somewhere else. Did you check it?

Tom, Its not the scale but the switch itself because while zeroing, if you activate front limit switch for Y axis, Beam should travel back to look for home pulse. It looks like switch signal does not reach to the system.It is really hard to trace the

I have GSM1 (OS/2) machine and it does not zero. The Y axis comes to all the way front to hard stop. I replaced the limit switch before the hard stop and can not find any way to test the signal from limit switch in diagnostic. I like to replace the c

Try cleaning the linear encoder reader. I've had dust build up on two of my machines resulting in failure to calibrate. Blowing out the reader heads with gentle compressed air resolved it.

Have you reviewed the wiring diagrams and checked voltages at the input card? Maybe you have a damaged IO card or broken cable.

Is the y axis sitting on the out of limit switch by chance

Well, we finally got the machine to power up and fully boot, but now we are having issues with zeroing the axes. X, Y and Theta zero OK, and the board conveyor runs, but when it tries to zero the PWC, the rail moves to the rear of the machine, hits

Hi Marco, most likely your axis has two limit switches and possibly a home sensor. Limit switches are NC and in case of bad connection or wire break the axis will not move, no matter how many cards you swap.

We are parting out a GSM2 machine and plan to keep most of the parts for spares but if there is some bracket, bearing, roller, switch, etc. that someone needs let me know asap and we'll see if we have it.
