    Hi all! I recently set up my acro 1010 system and I bought everything from open builds that is suggested, my question is this, I bought the nema motors suggested, does anyone know the maximum speed in mm/minutes they can handle without issue? Purely for non cutting movement as a 32"x32" cutting area takes quite some time to move around at at say, 500mm/minute, I'm looking for the flat maximum so I can hopefully cut down on job time when it's moving between cuts when doing big projects

    At least 3-5000mm/min, and if you tweak your acceleration and have a spot on mechnical build, you could go higher

    Just double the speed till it fails to move properly, then try 'previousworkingspeed + previousworkingspeed/2)
    Then double the acceleration till it fails and go back to the previous working one.

    For more fun you can mess with both of them, you can have insane acceleration but top speed will be severely limited, or you can have crazy top speed with limited acceleration.
    But keep in mind that high acceleration causes 'jerk', the entire machine may walk across the table but worse is that it can affect accuracy in corners.

    Thankyou both for your answer! I was hoping to hear something like both or either of the answers! I was just hoping that if I pushed the motors too hard they'd show me in a way that wasn't just "yeah, I'm broken now." As for acceleration, you guys suggest a good acceleration? Everything was built carefully, I squared EVERYTHING up before bolting it to my table and everything is bolted nice and tight on the entire machine so I'm curious to see exactly what this thing can do, I'm just sad that I can't find a stronger laser for it so it can cut and engrave faster, I'm finding my 20w diode a bit limiting with cut speed, but I'm thinking acceleration may help a BIT

    I think the conventional wisdom is that the diode wattage given by the sellers/manufactures are very exaggerated. Most likely your 20W diode is not really 20W but much lower which will explain the lack of speed.
