QUAD 4c big placement delay

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.

Good job, For the comm errors i would try: 1. Reseat all the cables that plug into the white multiplexer that is attached to the back of the computer. 2. Reseat the EPCU card down inside the machine. good luck, Merry Xmas, Bob

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

It sounds like the vac-verify is not working. There is a command on the hht to turn it off. When turning off your hht will show either 'idle' or enter command' without the V showing anymore. Maybe try the cntrl and vacuum or shift and vacuum. If its

Make sure your placement rotation co-ordinates are correct. If you do a function 3 it will show you. I think they should be in multiples of 6000....ex...6000 = 90 deg. Also check the z axis number. I dont think its cyber or vac related. It is somet
