Does it error during nozzle center check, if so, manually switch all holders to small, try center again. It should do about 8 small nozzle centers before error, if so this helps rule out the 10th station, if not check the 10th.

I do not recall that "TEACH" ever worked. Even if it did, there is no way to save this data to the MCS. After you see that a fiducial cannot be found, change Xa-Ya in the program at the MCS to find it, and of course, re-transmit. Good Luck

What are the chances for redesign the board or use substitute for the current tall part? Sometimes the hassle you want to go through could be avoided. How about change the box the device goes to or modify/ customize it to fit this part better in?

Hi, has anyone experienced discoloration of cured non-conductive epoxy? It turned from white to deep red. The parts were returned from customer and we noticed the color change and wondered what could cause epoxy discoloration.Thank you!
