I just powered up my TRM for the first time yesterday and found one issue. The Y axis limits seem like they are offset. Does anyone know how to fix this? Or, do you know a tech that would be willing support this issue over the phone?
First I line up the markers and then I run a CS command to perform the cold start function. This appears to work. Next, I put the machine in jog. The Z axis will move 14 inch, as it should, and stops a few inches above the table. The X axis will move 15 inches from the home posision to the right or left and stop as expect. The Y axis move away from me 15 inches and stops, but there is 5 or 6 inches or so of linear rail unused. When moving the Y axis towards me from the cold start position, I have to stop at 4.5 inches. Any further and the the machine will be at the very end of the linear rail and hit the hard stop and have Y axis fault.
This picture show's where the Y axis stops when I jog the table away from me.
This picture show's how close to the end of the linear rail the table has moved after it has moved 4.5 inches.
You have to stop or the software limit stops you before you jog off? Been a while since I worked on a TRM. The Y axis CS position was always the center of the center T slot. Take a coaxial indicator and put it in a tool in the spindle. Dial in the middle of the T slot. Not exactly sure with a TRM..
