Yes I used the copy I already had, just recompiled. Yes X and Y worked fine

Thank you for the feedback. And it is good to hear that you have resolved your issue. If you would like to find a root cause - then if reinstallation od software helped after you "deleted your Marlin" and "a fresh downloaded copy" worked better, then maybe there was a difference in (1) configuration or (2) the code (at least version of Marlin). If there are no justifiable differences, I have a very good theory - so I will improve my answer.

The only problem with possibility 1 was that the printer was running. It had homed and started printing. I then Paused using octopi (pause button, not in terminal) and then used the controls to try and move Z up and that's when it stops. So there was no M92, or any other commands, used. I appreciate the support.

First I suspected this could be faulty Z motor cable (broken wire, etc.). The G-Code `M122` is for communication with the driver board. There can be almost no feedback from motor itself (there are just 2 pairs of coil wires) ...almost, because we can see `Testing Z connection... OK`. But anyway, to be on safe side, did you doublecheck with multimeter that Z motor cable is properly conducting? (There is only one Z motor in this printer, isn't it?)

Sincere apologies for your question being temporarily closed - it was an admin error. Please add the "Update" as an Answer, even though it wasn't quite resolved, because putting the solution inside the question breaks the Q&A mechanism of the site. Many thanks.

For "suddenly have this issue" the only explanation I have is that of Z steps/mm set to 0, and could happen unintentionally (from LCD or with `M92`). *(Unless someone recompiled firmware with changed settings, then it's suddenly no more.)* So @Gaz83, could I propose to accept my answer and have this question closed already?

# Z axis no longer working on a working printer

(Asked by: username_0 on 2021-01-24)

I was printing an object and it started to drag so I stopped it.

Went to move the Z-axis up so I could clear the bed and Z-axis would not budge.
I switched the printer off and manually turned the motors to get the Z up.
Cleared the bed, switched on and homed the printer. When it came to home the Z, BLTouch deployed and then nothing. Motors will not turn.

Things I tried:

* Recompiled the firmware (Marlin 2.0.x)
* Different motors - Motors were free from the printer, just resting on a desk so I know it's not binding or anything.
* Swapped stepper driver with a known working one.

Info about the printer:

* CR10s
* SKR1.4 Turbo board
* TMC2208 Steppers
* BLTouch
* Octopi to control the printer.

It could be caused by software or configuration issue.

# Possibility 1: just worked after re-installation of Marlin

You could have Z steps/mm set to 0 in EEPROM, and did not notice that fact.
It is possible to fix this unconsciously with Marlin software reinstallation, following the upgrade procedure which included reset of EEPROM settings - like "Step 4: Finishing touches" described in [community wiki's guide for Updating Marlin Firmware](https://3dprinting.stackexchange.com/a/12154/26170). This is described in more details in another post [No stepper motor movement on Ender 3 Pro](https://3dprinting.stackexchange.com/questions/15307/no-stepper-motor-movement-on-ender-3-pro/15326#15326).

# Possibility 2: Marlin configuration is not correct

When you recompiled Marlin, did you use **already proven configuration for Marlin?** When saying "Motors will not turn" you mean only Z? Are your other motors are still functional now after Marlin was deployed?

Among other Marlin settings, you may want to check that this line is disabled in Configuration\_adv.h:

```
  /**
   * Software enable
   *
   * Use for drivers that do not use a dedicated enable pin, but rather handle the same
   * function through a communication line such as SPI or UART.
   */
  //#define SOFTWARE_DRIVER_ENABLE

```

Issue seems to be resolved. I deleted my Marlin copy, downloaded a fresh copy and I started again.

What worries me is how a working copy and a working printer can suddenly have this issue. Feel like this issue could come back as I never found the root cause.
