Below is the sequence of events and symptoms in chronological order.

Accidentally ran our desktopmax with the zero clip hooked to the spindle which took the wire out of the plug connector.

We reconnected the spindle wire, or so we thought, it was not fully connected.

Went to rezero the bit.

The bit came down and instead of touching off on the plate like normal it repeatedly hit the zero plate, we had to hit the Estop.

We hooked the wire up for the zero then correctly.

We zero'd the unit and then resumed cutting.

Within a few seconds of resuming the desktop max would not proceed in the X axis and made grinding sounds. We hit eStop.

The unit would only run normally then for a minute or two then start "grinding" in all axis's.

Then we got a hold of John in tech support. Troubleshot for 1 hour. Diagnosis was we needed a new circuit and control board.

We got the new boards the next day we installed the boards.

After installation the gantry would not move in XYZ, but the readout on shopbot software on the control panel indicated movement, but physically was not moving.

Then after the machine sat at rest for 30ish minutes the gantry would move with terrible grinding noise.

We rebooted everything, re zero everything.

We start to run a simple cut and get a horrible grinding sound in every axis. The problem seems to be initiated in the x axis.

Also of note: After shutting the machine down from an event while resting the machine makes little noises that seem abnormal to us (we have been running for 6 months we have not heard these noises before).

Please help, or production is halted and we are loosing money each minute the machine is down. We are a small business so this is really painful. Much appreciated in advance for any help.
