The next (in my opinion) most likely cause is mechanical - perhaps check the grub screws / coupling etc. for tightness on the Z axis.

Probably the best suggestion would be to half your Velocity and Acceleration settings (in motor tuning) for the Z axis and see if that cures the issue.

how can I import a G code file and tell what the properties of the file are like units (inches or mm) or output size.

Once you have loaded a GCode, open the 'Toolpath' screen and 'Program Limits' show the size.

Could you tell me why it's considered bad practice? I had plenty of motors and I figured that double the motors would be double the torque? Plus I have a 22,000rpm router as my cutter so I'm just using the slide on that for my z axis and it needs the two pressure points to keep it nice and straight.

I understand your reasoning but both the TA8435H and TB6560HQ chips have been designed to handle just one motor. A web search should reveal the technical data, design data and manufacturers application notes should you wish to research this in more detail.

Basically, each stepper motor should have its own, dedicated, driver and ‘slaving’ of two axes (within Mach3) is the usual practice when two motors are used to drive together.

However, don’t let this stop you from trying your design ideas – stretching the envelope and thinking outside the box is true innovation but you should perhaps be prepared to run into problems which others before you have already discovered.

HYU…
Dongguan Hungyu manufacture various stepper driver boards which are then marketed by other distributors etc under different names so it is difficult to identify which one you actually have.
As far as I am aware they all use either the Toshiba TA8435H or the Toshiba TB6560HQ driver chips and you need to identify which of these you have fitted.
Replacement chips are available from many different sources / suppliers but I would suggest an ebay search for the best price.

(Interesting that you are using 2 stepper motors for each of the 3 axes. As a general rule, it is not considered good practice to connect more than one stepper motor to each axis output from any driver board although I understand that it can be done).

Hope this helps.

Excellent work Chris.

(Interesting about only working correctly after the second run).

Do you have any details on the controller board or a picture perhaps ?

Hi Alex,

Welcome to the forum.

Seems like you have done the right sort of trouble-shooting and assuming you have the micro-steps and drive current set correctly for the axis in question I would suspect the driver IC chip on your circuit board for that axis. If it is Toshiba then perhaps not too difficult or expensive to replace it and see what transpires ?
