Mod code 7 is a placement delay.....changing it will slow your entire program down. If you just want to slow it down for 1 placement.....you have to insert a mod code change in the sequence steps....this is easily done in central controller. Good L

Thank you for your answer. But maximum value for modcode 7 is 255. 255x3.3 msec is 0.8 sec. And I need 2-3 seconds...

Sounds like its just rejecting parts. Either the length and width of the component is wrong or the tolerance is set too tight. I don't remember the function codes to edit the tolerance but I left them at 30% (the max) and never had any problems with

Also check the lae on the pickup that is being dumped. I think its function 16....make sure that the alignment type is 0.

Hi, I'm using a "ye olde" Quad 4c Mk2 built in 1995 for eight years. During that period I had to change 3 HDD (now it runs a compact flash with and free DOS), 3 Z-rod bellows,3 laser heads, some monitors, nozzles and misc parts. Despite that it has t

Hi again Bob. I have checked the machine and it resulted that the files of that program were corrupted in some way. All other programs worked fine. I have a back up copy of all progs in a different drive so I fixed it. Two days ago there was a huge b

Thanks for that Steve - I'll try anything at the moment, but that sounds like a reasonable suggestion. I've already replaced a few cables that looked dodgy, and the LEDs on the LED rings, but I've not done a ribbon cable on the head yet. I shall hav

Hello DWL, Thanks for the response. I've measured the components with a micrometer and set the sizes. Maximum tolerance on my machine is 20%, and that's what I'm using. If I do a manual scan, the measurements are exactly right (and what I've set up
