Hey everyone looking for some help with an issue I'm having on a Makino Duo64 Wire EDM:
My machine was displaying a wire break alarm at the beginning of the cycle immediately following the M06 line. The wire wasn't broken, it'd run an M07 and then begin to rewire -- rinse and repeat. I went through the entire machine picking away at all the variables one at a time, played it safe by re-verifying my part zero, and so far nothing has worked.
I ended up adjusting the powder clutch most recently. I ran the clutch adjustment cycle and closely followed the owner manual, and I had my tension gauge repeating 250g for the 3rd check and 850g for the 4th check. I ran this twice to be extra careful. I just went to go edge find my Y-axis and found that it was barely repeating within .0005". I paid closer attention and found that the d-roller (powder clutch) wasn't rotating during the pick-up cycle and I could hear the k-roller (lower roller) tugging at the wire during the cycle. Typically, the two rollers are both rotating during pick-up cycles and I was wondering if anyone else has had this issue after a powder clutch adjustment.
Also, hopefully the false wirebreak alarms will be solved by the clutch adjustment, however, if not... Does anyone have any suggestions on what could be leading to this false detection? I have been pecking away at the issue one variable at a time, I even removed the tube leading from the front of the machine to the wire collector and performed all PM on the gears and wire flushing in the back of the machine, I've sifted through all the consumables and had another tech overview my program. I'm sort of at a loss here. Thanks for any input!
