Light Machine Corp. Benchman XTr (retrofit)

That's really interesting, but that would mean 7.5K cannot have a tool changer unless it has a different method to index the spindle. Were there toll changing models that ran at 7.5K?

Steve, you are correct. The 7.5K spindle used an external prox sensor to create the spindle home signal. Spindle Home is not spindle in position to do a toolchange, that is an offset from spindle home. The spindle home sensor is wired to J24 in a single control board Benchman, or J528 in the original multi-board configuration. I do not recall exactly what the sensor was detecting (flat or flag) on the spindle head.

Hi guys,

First time posting here. I just picked up a benchman XT as well with a connection problem. I think its the pc card, the company I bought it from said they couldnt fix the issue and I messed around with it with no luck. So I think I have the same problem almost everyone else has had.
I think I have to get a new controller which I am ok with, Id rather the machine run on more readily available parts. If I read these 35 pages correctly, scanning the relevant info, my best options options is to get a Mesa card and use that to communicate with the existing servo drives(copley), spindle(ultradrive) etc? Does anyone have better alternatives to get up and running asap besides paying $4-5000 for a used Nextmove card? Appreciate any feedback.

James are you 100% sure that your problem is the Nextmove card? If so, then moving to another controller is your best bet.

If you are not 100% sure, I may be able to help you determine the issue. Please provide a photo of the main control card in the rear of the machine so I can determine your configuration.

Thanks for the reply, if you have any tips, it would be much appreciated! I was told it worked, then the harddrive crashed, an employee there tried to reintall everything but couldnt get it working. Here are some pics:

I couldnt find device manager to set the right register, Im hoping the software included could do it. Otherwise Im not too sure what else to try...

My Nextmove card is a bit different than yours. Mine does not have the daughter board with those two cables going to the PCs I/O backplate. What was connected to those to cables? The card looks to be OK; you've got the right LEDs lit.
