Currently working through a myriad of air leaks on an old MPM Ap -b and have a question that hopefully one of you fine people may know the answer to. The camera vx and vy use linear rail motors. As far as I can tell, there are nozzles between the sur

Back when the Linear Y wagons first came out Mydata had problem with the original Y amplifier and were swapping out the complete box for customers who had problems. There was also a problem with the encoder that resulted in the same type of errors yo

The camera is not driven from the motor cards. The camera is attached to what is called a forcer. For the Y axis there are two of them. One is wired backwards from the other. one of the forcers is connected to a flex chanell for the air and electrica

Don, either you have a faulty park sensor or much more likely the vision gantry Y axis is not reaching the sensor. Possible issues, one of the two VY drivers cards is failing; one of the VY forcer motors (air bearings) is failing; to much air leakin

Scratches do not necessarily mean bad! Usually the forcer motor fails before a platen. The motors become weak or don't evenly distribute the supplied air, which causes them to tilt and drive into the platens. Mechanical misalignment of the VY forcer

Linear drive uses linear motors that have no moving parts, strictly a coil over magnets. "Rack and Pinion" as you call it uses AC servo motors that are driving belts and pullies The linear motor has no moving parts and is faster but generates a lot

Wouldn't the VRM linear motors need to be replaced eventually? How long do they generally last on the genesis? Replacing a ball and screw is not cost prohibitive but the linear motors sounds like it would be. Wouldn't that be the life of a genesis

Sorry I didn't catch your message sooner! 20k is way to much. The odds of you having 3 bad platens and 3 bad forcer motors would be very unlikely, unless the machine was sitting outside or something. If it is a 10 year old AP then I assume it must

We are having a problem with our AP-24x printer. When the vacuum motor spins up we get a 60 hz buzz into the DC drivers for the forcers and the stencle wiper. We also indicate a main power drop from 115 vac to 80 vac. The vacuum motor checks out good

I have an ap-25 and wish i had gotten the UP-2000 instead. How's that for an answer? The main difference is that the ap-25 uses linear motors and air bearings, whereas the up-2000 uses ball screws. The linear motors are faster, but the whole thing i
