So my lowridier v4 when Y set to 10mm motor0 gows 2-3mm and motor1 gows 5mm. i have the Jackpot board and i had to change the Z1 from port B to C.
The mashine is squere i think but the ishu is that is dreailin once i move the Y.
Aswell as i tried to runt the crown file without any sucsess of that. In the yaml file there is nowere to corect the steps pur each driver where i can see. and mi geting error that TMC drivers are mising on startup with $SS. If any can help will be appreciated.
Welcome to the forum!
What does $SS say when you type that in the terminal? Can you copy / paste that here?
You may want to check the gear pulleys to make sure that they are identical. Some people have inadvertently mixed 16 tooth and 20 tooth pulleys, and ended up with results like you are experiencing.
Ok Im away for the day from the workshop but tomorow i will upload the $SS result image of the board and the config.yaml file. I dont think the gear pulleys are difrent as i bought them together (16 tooth).
Thanks
Are the motors also identical - there are 0.9 and 1.i degree stepper motors, if you had one of each I guess that’s what it would do.
That’s what some other people here thought, and then found out that one incorrect pulley was shipped along with the rest being correct ones…
Doesn’t hurt to double check.
Some people have also found the belt riding on the outer rim of one pulley instead of against the teeth, which affected the distance on that pulley.

Yes the motor are idetical Nema 17 84oz.
So will attach all of the info that i can get.

The Stepper motors are the same, the Gear pullies are the same. I had similar ishu with the Z axis thats why now one of them is in C slot.
Thank you for the help.
Why do you have a USB cable plugged in?
You need to power up the board from its DC supply before plugging in a USB cable or this happens:
[MSG:ERR: X Axis TMC driver not detected - expected 0x21 got 0x0]
[MSG:ERR: Y Axis TMC driver not detected - expected 0x21 got 0x0]
[MSG:ERR: Y2 Axis TMC driver not detected - expected 0x21 got 0x0]
[MSG:ERR: Z Axis TMC driver not detected - expected 0x21 got 0x0]
[MSG:ERR: Z2 Axis TMC driver not detected - expected 0x21 got 0x0]
Can you power it up with the USB disconnected and run $SS again please?
Edit: oh and have you checked the stepper pulley grub screws are secure?
So i have checked the grub screws and they are tight.
I furst power on the cnc then i conect it to the laptop to see $SS. It gives the same outcome.
And chekt if there are any gunk or thing that is on the pullie.
Thanks
Are those TMC2209 stepper drivers?
Yes they are
Your TMC2209 module UARTS are not communicating with FluidNC.
You will not get correct motion until FluidNC can correctly configure the Drivers.
Some TMC2209 drivers need to have zero ohm jumpers moved around on them to correctly set the UART pinout. Your modules may be that type.
Willchek that i think i have to remove MS1 and MS2 pins
Did you change Motor 0 for some reason? Ryan’s config.yaml doesn’t have that.
You need to change Motor 0’s microsteps to 8 also. Then they should move the same amount.
So i think the drivers are wrong a plugged in a difrent tmc2209 and i had Y working fine and corected the microscopes to 8. But i accidentally plugged in one of the drivers wrong and blown up the ESP32 So now i haved orderd a new one and will chek and update.
Hopefully i havent damaged the jackpot controler.
Thanks for all the help
