Do you think having too many steps specified in Mach3 (ie 10,000+) will result in these conditions? Best to keep in the low thousand range?

I guess I am having trouble understanding why the such wide range in microsteps on the driver when you can do your speed manipulation in Mach3?

It is a 8mm pitch. I've confirmed this with the manufacturer. I could be wrong on the 400 steps/rev (is this the same as pulse/rev?).

Regardless, in your experience, what conditions would cause a skipping/pulsing effect on a jog, but diminish at lower speeds?

Here is a picture of the driver showing the different options. I have it set to the highest amperage, and I believe 400 pulse/rev.

Here is the driver I have. If you zoom on it, you will see the pulse/rev on the front of it. I believe I set it at 400, but I could be wrong as I am out of town and away from my machine.
I also attached a screen shot of my mach3 motor setup.

400 microsteps on the drivers.

I have to be completely honest here, setting this up was completely hit and miss. Knowing what microsteps to pulse/rev ratio to put into Mach3 was guess work. Yes, I did calculate the correct pulse/rev and it is accurate w/in 0.002", which is fine for me and a wood router, but at the end of the day, I went with what sounded didnt make the motor growl at me or go to fast.

Sorry, I was mistaken. It's 8mm/revolution. I have my drivers set at the highest amp (3.5amp). For the steps/rev, I have it set in the 10,000 range in Mach3. The machine has a max feed rate of 240 IPM with a suggested of 60, so I'd expect it shouldn't struggle at all at 30IPM. After all, the machine was designed to cut that fast. My Mach3 velocity is set to 90 IPM, and acceleration to 10 in/sec^2.

Am I setting up the motor tuning in Mach3 correctly? What about the settings on the motor driver? Is it better to have higher or lower pulse/rev?

Thank you all! I value your input greatly!

Nema 23 2.8A/Phase, 24v 8.3amp power supply, drivers: https://www.amazon.com/gp/product/B016ZJS1FA/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1

Pitch is 2mm.

Velocity and acceleration I'll need to look up when I get to my laptop.

I am new to this forum, so I apologize if this is posted in the wrong section or redundant.

Earlier this year I put together my first CNC router. https://www.smw3d.com/r7-cnc-diy-kit/ I used a Mach3 usb board https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board with the other components from the kit.

Everything was working great until I started a cutting project that lasted about 1 hour. Running at 30 IPM, it will lose either X or Y positioning and try picking it up again from 1/8" off to 4" off. I also notice that when I bump up the jog rate to 150% for positioning the router, it will stutter or pulsate. Slower feed rates do help eliminate this.

I believe I set up my motors correctly in Mach 3, but has anyone else ran into these issues, or have suggestions on what it could be? It's really frustrating being almost done with a project and then have it ruined because it loses position.

Thanks!
