I will preface this with the fact that I don't have a ton of experience on WEDM machines. This machine is used in a prototype shop so it doesn't get run a lot. We generally use .010 wire but we have some parts with .007 features so I need to use thinner wire and the only other set of guides we have are .004.
My issues start with the wire wadding up between the first set of drive rollers and the guide tube leading down to the wire cutter. It usually starts wadding up as the wire is trying to thread it seems to bind up either when it first starts moving, when the water comes on to guide it to the lower guide, or when it gets about to the lower guide.
If it does manage to thread all the way through (maybe 25% of the time)it seems to almost always miss the funnel to direct the wire to the chopper. I found if you grab the wire and yank and manage to break it near the rollers it gets another chance to funnel into the chopper.
I have only gotten to this point a few times and everytime I have managed to the wire breaks about 5 to 10 seconds after I turn the wire on to edge find in a +Y direction, moving in X seemed to have no issue.
I was wondering if anyone had any advice or experience that they could share. I haven't been able to find an setting to change tension for the thinner wire but I could have easily missed something.
