Checked out the control box internal wiring which appeared ok...no loose wiring etc and everything solidly bolted down.
At the moment we are able to run ok on approx 50% of the bed without problems which enables us to continue and produce parts (for the moment anyway!)
In the meantime I will make up a new cable if i can work out what the connectors are!
Thanks for the suggestion Phil!
I made up a new cable this evening and although i havnt tested it in anger yet, the z axis does seem to work ok while moving the gantry back and forth.
Hopefully problem solved!!
Bugger me my machine went and did this yesterday.!! . . . I've just transfered all my control box into a new larger box. . . . I knew straight away what it was and to be honest I'm embaressed that I didn't think about it in your case.
It's one of the Dir pin wires thats either come out at drive or connection/wire come lose in motor. To be honest I didn't expect it to behave how it did.? I expected it would only move in one direction but it infact it was moving in one direction then changed direction randomly.!!
LOL , its catching, must be a virus going round!
Anyways were back up and running ok after replacing the cable...must have been a spot somewhere along the length of the cable where there was a breakage but making contact depending on where the gantry was positioned.
Thanks once again for all your input its been very helpful and much appreciated as usual!
Ho Hum...now what?...the spindle motor brushes have worn out!! After approx 6hrs intermittent running!!
Plus the remains of one have dropped inside the motor..lol..
So the saga continues....
Should still be under warrenty shouldn't it.?? . . Or is that has much use as the spindle.!!
Got a single speed Kress here if you are stuck and a mounting.John S -
Edit: Stripped it down and cleaned out gunge and brush/spring remmants etc.
Bottom bearing dosnt feel right but will run it later to test.
Ran it but its eating the brushes and sounds terrible...probaly bearing problems..
