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)
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!
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... 
I did try 5-7 first and thought maybe I had a board or driver issue so moved for testing
Have you swapped the stepper modules around to check if they work in another socket?
Yes z1 and z2 were moved into z spot at least once
Are you using MAX EZ by chance?
Yes, I'm using the same board
Could I see your printer.cfg and config.cfg?
I vagely remember testing 8-10 once, and I think it did work. So I'm not sure whats the issue
But I reverted it because of the cables exiting inconvenietly (getting to close to the fan mounted on top of the board)
I'm using 5160s on Z so my cfg will be of limited use.
The board's config.cfg is literally the same as yours already (might be mine) :P
Could be I got it from a github
I was going to get 5160's for Z but was talked out of them
tbh I'm too afraid of crashing something, so they are a waste of money 
should be the relevant bits
should be the relevant bitsThat was my reasoning for wanting all 5160's
I'd suggest to try and roll back most of your manual pin overrides and test 5-7.
Maybe even start with a fresh printer.cfg; you only should need to add the things I told you in my first posts (all the pin names come from the config.cfg).
The stepper module power jumpers are certainly set? 
I’ll try the 5-7 and fresh printer.cfg.
Pin 'x_uart_pin' is not a valid pin name on mcu 'mcu'
is it this file causing uart_pin error?
It might be, if you still have the line defining x_uart_pin commented out?
It is commented out still. I only redid the printer.cfg
Well, then please uncomment these lines. They are necessary to define the pins
Trying now
No errors after restart. Z and z2 worked. Looks like I have a wiring issue on z1. Thank you so much for your help.
perfect!
Got wiring issue fixed z1 came back good. Off to test the rest. @mietzekatzi thank you again
glad to hear 👍
