The config I posted in the config repository on the main page is for my 1050 workbee using a mb36hc as well. You can compare it to yours or copy the I/O wiring and upload it as-is and give it a shot. I definitely recommend keeping the stepper-to-leadscrew couplers loose while testing. You can confirm motion in all directions, endstop activation, home.g files, all without the possibility of crashing anything.
Do you get any error messages in the web interface when attempting moves?
