    I've been using xPro with AcroLaser for 4 months now with great success. The board has accumulated at least 100hr of trouble free operation. This morning, I turn it on an noticed that drivers are not locking in place like they usually do when the power turned on. When I issue a move command nothing happens! The M5 commands turn the laser on/off no problem though. the voltage on the board input is stable 24V. what could it be? What can I check?

    Do you have a fan for your xPro?

    No, it's open air with heatsinks

    Without a fan the xPro tends to overheat. If it doesn't work after the board has cooled down there is a good chance that the board is fried.

    Thanks for the tip. Alas it was set to 1 already and still no move commands possible :-(
