Y axis stalling

[richie00boy]

Not sure what you mean there, the noise is the stalling. If the machine has been on about an hour it seems more prone to it. If I was to rewire it any ideas where I can get replacement connectors to fit the blue control box?

Is the nut the part in the housing that the leadscrew tuns to move the gentry up and down? I have tried moving the stepper motor by hand to feel for any tight spots and there didn't seem to be anything that bad.

The stalling can happen anywhere on the y axis, doesn't seem to be related to x or z axis position.

Maplins sell the connectors :)

I had to replace the x,y and z cables on our machine to keep the machine going, although i used standard connecting cable because it was all i had to hand at the time. Machine has worked ok since.

Swap the cable over and see if the fault tranfers to that axis which should confirm a cable problem.

That noise doesn't sound like stalling motors it sounds more like a binding or sticking bearing or tight leadnut. The leadnut is the plastic part that sits in the housing that runs up and down the threaded shaft and is located under the bed in the centre of the gantry bolted to the cross brace.

You can re-use the connectors just de-solder them.!
