Hi Sound like the same problem that i had. The machine after it had warmed up when initialising would drive the z rod down with the quadalign on checking for the nozzle height (I think). To me it seemed like an overheating problem as after allowin

The way its supposed to work...is....when you do a function 30 the z axis should step down until the nozzle tip is seen in the quad align or laser align. The readout should have a nozzle height but if its the earlier firmware for the machine it might

I found problem, it was a faulty connector on the align processor card. So, Mr. Bobpan, I thank you very much for your invaluable guidance. P.S. My employer has been very clever and have purchased a 18 years old/ 25000 run hours/ third-hand equipmen

I work on a few of these Universal machines before. Check your severos ( I believe their 6 of them ) in the back of the machines all of them should be on. If you see a red light on one of them it's gone bad and that's your Y axis card. It's easy to

We swapped the Y1 and Y2 pc800 controllers with no change. We swapped out the UIMC III-I cards from another machine with no change. VRM amps all look OK, no errors. The machine moves the head both in the x and y directions during the zeroing attemp
