Try a different port.Īlso, Mach 3 is famous for hiccuping if you are running other applications at the same time. Check to see that your USB port is not damaged, laptops seem prone to baked USB ports. As I said before, use the shortest USB cable you can, keep it away from power cords, and make sure it has the ferrite “Lumps” on it. If it loses connection, it would cause it to stop executing.
From your description, it may be something to do with the USB connection. It’s just executing the g-code sent to it. The router doesn’t know the difference between a 2D and a 3D cut. You may need to increase the pulse width on the motor pulse output, I don’t know what the specification is for the NVUM, but if the pulse width is too short, it may miss some. What is the motor maximum speed? Here I wouldn’t use more than 3000-3500mm/min with standard 1.2N/M motors. Make sure your USB cable is as short as possible, and has ferrite “lumps” on it to reduce noise.ĭon’t plug the router into the same outlet as the machine power supply and What do you have your motor acceleration set to? I would suggest no more than 50 or 60 mm/sec^2. Check the locking collars on the leadscrews to make sure they are tight and not allowing end play on the screw. If you can’t turn them by hand, or they are very tight, back off the adjusters a bit. Wheels should be tight, but you should still be able to turn them manually with your fingers.
#CNC USB CONTROLLER DEPTH FREE#
You should not feel any “clicking” or free play in any axis. Circles should be round and same radius all around, squares should be square and same width as height.Ĭheck to make sure all axes have zero play by grabbing the carriage and trying to move it side to side, forward and back, and up and down.
#CNC USB CONTROLLER DEPTH DRIVER#
Check the motor and driver wiring to make sure you don’t have a loose connection on the motor leads or one of the driver inputs.ĭo a simple g-code program with just a few circles and squares, run it, and measure them for size. I wouldn’t use 1/16 unless you have high torque motors. I also think you should use maximum 1/8 microstepping. I wouldn’t recommend taking driver power from the controller, because you could be drawing almost 12A if all 4 motors are running at once, who knows how thick the traces on the controller board are? Do not daisy chain driver power together, run separate wires to the supply for each driver. You should have each stepper driver power input wired directly to the power supply thru 5A fuses.
