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.!!

The Z axis wiring fracture is contagious, mine is just exhibiting identical symptoms.

There`s a cheep Chinese mill FAQ to be started here....
Current small Chinese mill FAQ thoughts ;-)

Out of the box;
Check the connections inside the control box.

( had E-Stop button connected to limit switch header on parallel breakout)

Check the bolts on the frame for loose or stripped threads.

(Stripped thread on carriage bolt, worked loose, no problem space to put bolt in place)

Check the life left on spindle brushes.

(couple of premature spindle failures reported)

Make up 4 core stepper driver and 2 core screened loom for Z- axis and spindle for when the original fails.

(early failures reported)

Cheers
Adam
