AM882 and Nema 23 Tuning

[JAZZCNC]

Ok well thats strange movement even if you had some switches wrong on drive so I think you may have motor phases wrong.? So can you post the wiring colours you have paired up. (and motor model)

Also I see your using a Laptop but you don't mention anything about Motion control card so I'm going to presume your using the Parallel port. Laptops shouldn't be used with the Parallel port as they cause all sorts of strange affects.! It's because of the way Laptops deal with saving power and also the fact they don't often come with 5V parallel ports and most are 3V which affects the drives in strange ways like this as there's not enough Logic differance in pulse strength so drives get wrong signals etc. If you look in the Manual or On Web site Artsoft state not compatible with Laptops unless using Exteneal motion control card and this is because of the irratic nature of using Laptops, some work, most don't.!!

Eddy's settings are correct except he's assuming your using Mach3 in Metric and I can see on the Video you have it set to Imperial as the feed is set to 6 and the way the motors moving that must be 6"min not 6mm. If you change to Metric in Native units then you must restart Mach and retune the motors.

The AM882 as feature that lets you auto tune the motor to drive by flicking switch (4) - 2 times in 1 sec but I find this awkward using the Switches so prefer to connect thru software using Protune. In Protune you can also set the Motor amps spot using the Current setting as it's setable in 0.1A increments. Using Protune takes any guessing away and you can also play with the tuning better and fine tune the machine if you want to. (The motors must be on the machine thou to do this properly)
You must set the rotary dial on the drive to (0) if using flicking the bean method or Protune.

One more thing while testing on the bench it's best to clamp the motors other wise resonance affects the motors!
