Hi. Sorry I don't have an answer for this but I have the same problem in the "Y" axis on one of my 4Cs after the machine has run for around 4 hours. The machine seems to partially correct for the pick-ups being off as the placements are fairly good

Hi Bobpan, Regarding "second", the results of the test are no difference - still rejects the part. I tried 2 mils, 3 mils, 5 mils, 7 & 9. I changed the tolerances fron about 15% to 20%+. By the way, I did put on the new nozzle and it is still the sa

I've got a scary one for you guys and desperately need your help - We just purchased a second Quad 4C and had some communication problems when we first turned it on (we're still working on that issue). To chase down the problem, we decided to start

I have 3 used Quad 4Cs and the nozzle changer on one machine never worked. I decided to troubleshoot it this week. I repaired the changer by changing a defective optical sensor but I still get error 17 when I try a run-step nozzle 1, 2 or 3. Error 17

Was running production when the head just came to a stop, motor went off, error window said to home. Upon attempting to home, got message: G1T2 homing error; index mark not found. I've tried rebooting the machine, but this error still appears. Any

Hi again Bob, I checked the theta motor coupling and the set screws are definately tight. I noticed that the theta motor drives an snti-backlash gear (nice design) so there is no play there. It appears that the gear drives a slotted shaft which is d

Hello, This is from my old documents....hope it helps. I would first try mod code 53 = 2 first.....if the machine is a 2C. The motor was known for causing this problem after getting old. These are all resolutions for motor error 4. Step Potential P

wow.....lets try some more things....... first....i think quad align error 0 has something to do with the theta number not being at 0,6000,12000,18000. I am not for sure about that but check it out by doing a function 3 on your pickups. second.....

I purchased a used QUAD 4C -136 and after a few months got the machine running 8 hr shifts. One issue I have come across is feeder drift. I kept re-aligning the feeder pickup positions but they would always change. Finally I got the time to measure

Here is a couple of things to look at: 1. Make sure the boards are plugged into the correct position. Also just leave out the transport card to see if its hanging up the machine. The transport board should be the board all the way to the right. 2. M
