Y axis stalling

[richie00boy]

Thanks Jazz will try what you said. I should point out that this is a new machine only used about 3 evenings so there shouldn't be anything worn. I have tried to search for problems with this machine and found some Youtube footage of a similar problem and they said it was the wires. I have tried jiggling the wires to reproduce the fault but can't. Also the Y axis wires never move.

I'm a total novice to CNC, is the lead nut the nyloc that is on the end of the y axis leadscrew? I contacted the seller (ebay) and they said not to touch this nut. Actually they seemed really helpful and quick to respond, but since I sent them the video they are ignoring me. I wonder if I have gone outside of some Paypal claim window or something, and they were trying to fob me off until that time.

One of the issues I seen was that the wires are too tightly crammed into the cable guide and rubbing badly. They where also unshielded and I'm sure some of the trouble was electrical noise was interfering with the steppers because when changed for shielded cable the machine was much smoother and sounded loads better.?

No it's the bit that's fastened too the gantry cross brace.

How long running before this starts happening.? Also is the noise I'm hearing there all the time or does that come on after time has well.?
