"I think your problem is much simpler. Replace the loose nut behind the machine"
No, just get rid of the employee if they continue to cost you money over stupid mistakes, or take it out of their pay...THEN they won't forget to do it properly.
Actually, it is simple to incorporate a popup reminder screen, although i have forgotten how. But recall when you do a Z level with the plate and after the procedure it pops up a message asking if you removed the clip and you have to answer yes/no/cancel ?
Well i'm sure you can incorporate a popup screen regarding turning on your vacumn that the operator has to click on before he can start the cutting process. Others can tell you how to do it, i have forgotten but that seems simple and you can log your files to see it is done.
