Just checking: Did you supply power (9/12 volts) on the QMX power connector? QMX doesn't use USB power...

I have completed the construction of my QMX. It does not power on. This is a list of what I have done to try to get to work:

Connected it to my PC via a USB C cable

Downloaded folder from QMX but no files were listed in the download
folder

The QMX did not show menu

Deleted the folder and performed another download and again saw no files, deleted the folder

The next morning I tried again and the computer did not acknowledge the QMX

I tried several more times with no results

Checked all connections and found a poor connection in the left rotary encoder, resoldered it and checked both encoders with a DVM for a short and there were no shorts

Rechechecked all connections, smds and through hole components for visible damage and no damage found

I connected the QMX again and the computer did not acknowledge the QMX

There has been "click" and it looks like it is using 155 ma on my power supply when I push down the encoder and then the amps go to "0" when the switch is not depressed

I have tried the jumper according to the manual and the computer does not acknowledge the QMX

I have downloaded puTTY and the computer does not acknowledge the QMX when the rotary
encoder is pressed (probably because the QMX doesn't turn on)

Do you have any suggestions?
