disabled vet needs help new CW machine Z truck dives down into board

[fwharris]

Thank you so much fwharris, that did it. I didnt see anything obvious wrong with it but had a spare, put it on and it started carving the first time. Thanks, i was about to have a freaking breakdown because ive been fooling with this for so long.

Thanks for the feedback and glad I was able to help out. More times than not any bad or unusual Z movement can be traced back to either the FFC cable or the Z motor and or the encoder. Hope to see you back to making some saw dust.

Thanks again!

Glad the FFC Cable fixed it... Very hard to detect when they break as it is intermittent. I should make a tester for the cable with LED's... The hard part is buying the connector...

Yes, both the X, Y, and Z Motors have a Encoder Disk on the back. Here is a Y Encoder with dust in it....

Some pictures of the encoder and the cut motor brushes.

The Cut Motor Brushes and the "Y" Gearbox two 685ZZ Bearings should be replaced at 250 cut hours.

Good Job !!!!!
