Left z probe

agf998

Hi, I'm build a idex 3d printer, and the z probe is on the left head. I know that everyone says to put it on the right head, but i have no options...
So there is any way to configure this option in reprap?
Thanks

@agf998 Yes, it's just a number, an offset from whichever nozzle you want.

@kb58 ok, but where i can change it? Where i can choose that the offset is from U axis and not X axis?

Post your current config.g

@phaedrux this is my config, but i need to edit it anyway... but if you can explain me what to do, it will be great.config.g

@agf998 said in Left z probe:

M350 X16 U16 Y16 Z16 E16:16 I0; Configure microstepping (x16), Interpolation disabled (I0)

You'll want to enable interpolation for the sake of noise reduction.

What firmware version are you using? Can you post the results of M122? It looks like you're still using RRF2. Using multiple z probes gets a lot easier in RRF3 with the M558 K parameter. https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M558_in_RepRapFirmware_Num_3

I suggest you update.

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 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 RRF3. 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.
