UGS Alarm - Machine doesn't move


Scratching my head on this one. This is a new build and I’m on the electronics install step. I’ve tried installing UGS on two separate computers, and I have the same issue. When I connect my computer to the controller I get a positive connection. I’ve changed all the jogging step settings as indicated and have all four lights on the controller. No matter what I do “Alarm” posts and I cannot move the machine either via direct input of an X/Y/Z input, or by jogging. I’ve confirmed the wiring is tight on all connections and there is no binding on the machine.

Update: I reinstalled multiple times and now when I load up UGS I get the following:

I don’t know why the machine position is showing so far off and I cannot figure out how to reset it to zero. When I zero out the location it moves the machine to those inverted positions. I’m guessing the lack of movement I’m having is associated with this.

Any help is much appreciated!


Turns out all my problems were from the EEPROM settings being wildly incorrect.

I changed to:



This fixed all my problems. Machine is moving now.

Glad you figured it out. I’m curious how they got so screwed up. I thought the boards were flashed and checked before they left Sienci.

I thought so too. I woke up in the middle of the night and figured out what was going on. Now if I can just figure out how to send a Spindle On/Off command from UGS to the board I can start working on wiring things up to my VFD! M05/M03 don’t seem to do anything.

I’ve been thinking about going to a spindle, so I’m very interested in your VFD progress. Please keep us informed.

Have fun. Stay safe.

I’ve been trying to figure out the wiring for the VFD.

So far, my progress is in this post:
