Z-Steppers not functioningcorrectly
Question to those smarter then me. I have a Octopus Max EZ that I am having issues with the Z axis. When I do the stepper buzz test it works with stepper_z but gives the uart IFCNT error when I try Z1, Z2 etc. If I change say Z1 to Z and remark out original Z then that new Z axis works so I know the driver is good. I am curious if the system thinks I only have 1 Z and therefor the others fail. And if so how to go about making it see the other Z axis.

Ok, imho the config is a bit chaotic:
1. uncomment the lines with x and y pin names in your added config.cfg.

2. Right now the pin definitions in config.cfg aren't used. For them to work, (I think) you need to import them earlier, in the sections where the control board is usually placed. See the screenshot below
3. Uncomment this line:
[include RatOS/printers/v-core-3/steppers.cfg]

4. In the section
STEPPER MOTORS, DRIVERS & SPEED LIMITS
revert your changes, and change to this (for starters, you can enable performance mode later)![No description](https://cdn.answeroverflow.com/1133449667368198204/image.png)
5. Remove everything that concers pins in the override section at the end. This should be handled by the the boards config.cfg and the steppers.cfg
Ok, i see that you have 5160s on x/y, then in the stepper motors section do this:
And add the following things in the override section to replace the tmc2209.cfg:
That should be it
Thanks I’ll give that a try when I get from Dr appt
Excellent support there Flo
appreciate it!

Okay put changes in z1 and z2 still give Unable to read tmc uart 'stepper_z1' register IFCNT.
z0 gives new error: TMC 'stepper_z' reports error: DRV_STATUS: 00130090 s2vsa=1(ShortToSupply_A!) olb=1(OpenLoad_B!) cs_actual=19
Check that your driver jumpers are correct
This means your motor cable is miswired. Check pin order and redo your crimps.
Ok fixed the cable Stepper_Buzz Stepper=stepper_z works again. z1 and z2 still: Unable to read tmc uart 'stepper_z1' register IFCNT
In which sockets do you have the z1, z2 stepper drivers? And please post your printer.cfg again
Z is in 8, z1 in 9, and z2 in 10

Ok, I have placed them in 5-7 on my board. In this case you would not need to override so much.
The pins look okay though... ![THINKING](https://cdn.discordapp.com/emojis/540125325389201409.gif)

I did try 5-7 first and thought maybe I had a board or driver issue so moved for testing
