Desktop Max Proximity issues?? - Already tried circuit and control board

[jerry_stanek]

If you change the circuit board you will have to reload your firmware

Thanks Jerry...forgot about Firmware install
In Command Line....for Firmware Install...type UI and follow the prompts.
UR in command line reinstalls factory settings for your machine....good time to measure Z-Plate thickness and make sure it's accurate...follow the prompts and make sure you click "I have Z-Prox" as it's a better Z-Zero routine for dust foot etc.

UT brings up a .pdf explaining the UD info, after reading pdf.... Enter a move such as MX,4...and then doing nothing else....type UD, and check the Packet ET.
Should be less than 20, but have seen people with up to 25 run with no problems....
