Perfect. That solves the no-probe issue.
But I still can't move the Z motors. Any ideas?

Phaedrux

With the print head place safely away from the bed, send these commands to test movement

G92 Z10
G91
G1 Z5 F100

That should cause some z motor movement. If not, please post your config.g.

This may also be a good time to think about upgrading your firmware from RRF2 to RRF3 before you get too far along.

Your comment for the M584 command says you are using a Duex 2 board - is that correct? If it is you cannot connect 4 steppers.

I think you should update your config file by:

adding X and Y to your M584 command
adding a M350 command

@fcwilt
That is correct. I suppose I should go down the list real quick.
Duet Wifi (bought less than a year ago)
Duex to expand for 4 Z motors
PanelDue 7i

I'm basically finishing the build from another printer that uses the same electronics, and have just been modifying the files piece by piece to make it reflect this particular machine (e.g. this machine is a single extruder, non-Core XY, no probe, etc.) Hope that clears it up a little.

fcwilt

@azerate

Did you modify the Duex 2 in some way to support 4 steppers?

Frederick

AZERATE

@fcwilt

No. I simply copied the files from the other printer with Quad Z and uploaded to this machine, then tweaked as I went.

droftarts

@fcwilt where are you getting Duex 2 from? His M122 says Duex 5.

If you're willing to take the plunge to RRF3 now might be the ideal time to do, though it would mean starting with a fresh config file set. Though you'd be able to generate a good starting base to work from with the online config tool.

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
That will get your firmware and DWC up to date.

You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/Start

Backup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.

These documents will come in handy during the conversion.

@droftarts said in Z map with no probe:

@fcwilt where are you getting Duex 2 from? His M122 says Duex 5.

Ian

I didn't see the output from M122. His config file comments mentioned Duex 2 and I asked him to verify if that was true. He said it was. I guess he was confused.

I want to thank you all very much. I ended up deleting everything related to probe and G30 and now while Z motion homes rrrreeeaaallllyyyyy slow, I was able to make some calibration prints to dial in the machine.

This is a great community and I appreciate you time!
