Board: C3D Laserboard
Problem/ Question: A few days ago my lightobject z table stepping motor stopped moving the table up
or down, but does ‘buzz’ when a jog request is made. Occasionally it will move a few steps. I was able to get it working again by resetting (powering off and back on) the laserboard, but this was only good for a day or so. I tried to loosen the belt tension but this had no effect. I can get the shaft to turn only by removing the load entirely. I replaced the stepping motor but get the same results. Spins OK while in no load state but as soon as there is some load it just hums/buzzes. I have the gamma current already set at 1.2A in the config file. At this point I am thinking the output of the z driver is off. What would be the best way to measure current output of the laserboard driver, or do you have other suggestions?
