Hello, I am trying to run GRBL arduino nano laser engraver after arduino replacement, but without success. After the new arduino nano was attached, to the board I installed the 1.1f Hex file to it by xloader, after that the ch340 driver, when I enter Lightburn or laser grbl I can't move nor the stepper motors nor the laser itself even after the connection is successful, what could be the problem for that, is there something that I miss during the process, the machine is with grbl controller with ttl control. Also to mention that the machine was custom made and I don't have any schematics. Thanks in advance.
Please post schematics, and code ,in code tags. The sticky topic “How to get the best out of this forum” contains more advice.

What was the reason for replacing the nano? If it was damaged, are you certain the remaining parts were not also damaged?
it is attached from the bottom
It was not damaged there was a power change in the 20w laser module after an hour of work and just tried to replace the arduino to see if it will fix the the problem in the laser module but now I can't make the new arduino nano work, the previous one worked on that machine.
Are you certain you have loaded the correct firmware onto the Nano?
Can you post a link to where you obtained the original?
