Hi there.
I'm relatively new to all this cnc and milling stuff but after a lot of research and tips from people here I got things up and running.I'm currently using a desktop milling machine to cut pistol grips.I can cut 1 set out of a single piece of wood,first doing the top side,flipping it over and cutting out the underside and here begins my problem.
Instead of constantly changing drill heads, I cut out about 10 sets for the topside,change the drill and cut out the underside,but somewhere along the line the machine seems to go off by a few mms.I go to home before I start every piece.It's only when I cut out the underside that I see the holes not lining up.Is it possible that home is changing by itself ?.I've tried doing topside and straight away flipping over to do the underside and it turns out perfectly which means the code is good.It just seems that if I do a bit of repetitive work that it goes off.I noticed yesterday that from the 10 sets I made,the first 5 or so were perfect,after that it seemed to be going off a little bit more with each new set.Anybody any idea why this is happening ?
Thanks
Vinny
