Hi again, @cncsnw . Do you have any of those CRT cables like the one in your photo (p/n 1701150150) for sale?

Thank you. It's the Advantech PCM-4860. That's indeed the cable for the external VGA connection. Do you happen to know what type of ribbon cable is used to connect the controller's (internal) flat-panel display? I'd like to replace mine while I'm in here.

Thanks for this info, it's been very helpful. The shielded ribbon cable that connects to the integrated flat panel display is damaged, and I'm having a tough time identifying it to order a replacement. Do you know the type? Fortunately, the external display port is working fine, so it's not a show-s...

Hi cncsnw. You helped me replace the Z motor on this machine a couple years ago. Thanks again for that! https://centroidcncforum.com/viewtopic.php?f=64&t=4341&p=37330 I found the list of motherboards on your website. I'll pull ours to get a better look. If it's beyond repair, do you know if ...

The EPROM looks fine, it's just the area around the battery that may be damaged. It looks like it will be necessary to remove the board, clean the area ar...

A gib screw was incorrectly adjusted. My guess is the mill came this way from Wesel, and without manual control on the Z axis my dad never realized it. He's kicking himself for not having run the controller drag tests when he bought the machine, but he was still new to CNC at the time and I think it...

Hey, I think we got it. The drag test completes without error now. How does this graph look?

OK, here we go. Thanks for helping with this, Marc.

It wouldn't have been hard to change the wiring in the cabinet, but I ended up swapping the limit switches on the machine, which seemed easiest. No problems. Thanks again for providing detailed instructions. They made setting Z home a snap. Re-running the drag test on Z, I still get an "excessi...

Thanks for the quick and detailed response. I'll do what you described and report back ASAP.
