Voltage divider for Mesa THCAD-10?

...the machine moved but the stepper motors just kinda danced back and forth they didnt actually move the gantry at all. 

Any advice on why that is occuring?

Probably because the scaling, velocities and accelerations are not set properly.
My advice: Stop using chatGPT, it can not help with these types of issues, yet, set the values properly in PncConf, not just random values. Read about how to get those values right based on what you actually have on your machine.
Or take some pictures of the machine and upload them here, we can figure out a lot from pictures.

I used the same exact values for my AXIS setup. I didn't randomly guess them, they operate well on AXIS. My whole machine worked with GRBL for 2-3years straight no issues, i just couldn't achieve THC with GRBL & would sometimes have issues with EMI.

Setup:
7i96 with THCAD-10
Nema 23 495oz motors(1.8degree , 3amps max) with
TB6600 drivers(running 1/4 microstepping at 3amps max) (i will upgrade them later after i sort this out), two 36v supplies(10amp each),
SFU1605 Ballscrew on all axis'. 

(It was a somewhat budget build)

My stepper scale is perfect at 2032, max velocity of 150in/min(~3800mm/min) and max accel of 50inch/sec^2 (~1270mm/sec^2).

I've played around and purposely made the machine loses steps and it happens around 200 inches/min, 180 it stabilizes and 150 is what i chose as extra margin of safety.


I only used chatgpt for coding questions or how to edit bios etc, my master's degree is in AI (i'll be done in May 2025); Ironically I'm struggling to figure this one out..lol , but i will not give up ! Even if l have to read the whole entire LinuxCNC PDF and QTplasma documents or learn how the code itself works, i will do it!

 

 

Can you post your hal/ini files?
 

Thank you for clearing that up, although should have been at the very first post.
Your servo period set at 25597 was what sent me in that direction, that should not be edited normally.

Yes of course thank you so much for your help!
