Sorry if this sounds a weird or simple thing to resolve, but this is not exactly my thing. Working on a test file for testing engraving images power/speed settings and halftone options. I tested the movement with the arduino nano by only connecting the four mentioned pins from the nano to the shield. Ive been playing around with the Lightburn XML file format and created some online generators to create test files for Lightburn, They are for testing power levels and also scanline intervals. Do i have to make any more connections from the teensy to the shield or is this another issue? Motor connections are fine. However when i send a move command, the motor unlocks but it doesn’t move, locking again after a few seconds. I power up the shield and the motor stays locked even when i send the unlock command. I have connected the GND above th RX pin to the GND on the shield, the Step X to the matching pin of the nano on the shield and the same for Direction X and Enable X. The teensy is a replacement for an arduino nano.

I did manage to solve the error issue with the board by modifying the $14 setting. You have been doing a great work with this board by what i can see, and you have been sharing a lot of information.
