Swap the amps but first manually check by hand to make sure the z-axis is free to move up and down. Sometimes a part can get stuck in the gears. Good Luck

Miro, The video has nothing to do with the Quadalign. On a good startup and with no nozzle installed run a "Function 30" and post numbers that you get on the handheld terminal. On a bad startup (nozzle in the down position) press the re button on t

Hi everyone I have Quad 4C with following problem. When I run machine "cold start" first power up it will run and initialize but after if I turn it off and back on it will NOT initialize. Z axis will push nozzle down and it will remain i that posit

HI everyone, We are using a Siemens ap-25 screen printer, in the past we have not had any problems with adhesive placement until a couple of weeks ago. It seems the x axis has decided that it should be set somewhere between .00085 and .00150. No

This sounds like a Quadalign problem. Upon startup the Quadalign system checks runout of the Z-rod and tries to find the tip of the nozzle. It will keep lowering the Z-rod and looking for the tip until it hits it's limit. Check and see if the Quadali

My Quad IVc's will also do the same thing. Mine are equipped with CyberOptics scanners, not QuadAlign. The Cyberoptics scanners do go bad and once they do, they get very warm to the touch and at the same time, if the Quad is reset, the theta axis wil

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
