@phaedrux okay thank you.

and just to add while full step accuracy is often +-5%, accuracy of microsteps is basically "without any guarantee" since you're shifting around within competing magnetic fields.

If the bootloader does need updating, the files and info are here:

Okay.
Thanks

@user-m_123 it adjusts each of them by the amount it says.

Leadscrew adjustments made:(-0.074,0.006,-0.002,0.027)

So your first z motor will move -0.074, 2nd 0.006mm etc.

It is generally a good idea to rehome your z axis (with a single G30 at the centre, assuming that's how you home z) after doing the bed levelling, to reset the z=0 datum. Your bed is reasonably flat from the looks of things so may not give a problem, but mine has a substantial bow in the middle, so G32 moves all the z motors by -0.2mm, so I have to rehome z afterwards else I'd gouge out the middle of the bed when printing!

@jay_s_uk @achrn thank u

@user-m_123 from https://github.com/Duet3D/RepRapFirmware/wiki/Building-RepRapFirmware:

The build depends on the Eclipse workspace variable ArmGccPath being set to the directory where your arm-none-eabi-g++ compiler resides. For example C:\Program Files (x86)\GNU Tools ARM Embedded\7 2018-q2-update\bin on Windows (see step #1 for which compiler to use). To set it, go to Windows -> Preferences -> C/C++ -> Build -> Build Variables and click "Add..."

It sounds to me that you didn't do that step. The Eclipse project is set up so that Eclipse uses that variable to find the compiler.

Taper is described here: https://duet3d.dozuki.com/Wiki/M376

yes, you can add a single G30 at bed center to set Z0 to your bed.g and then load the heightmap with G29 S1.

However, that won't help for power loss recovery, you would still need to set Z0 in some way while the print is still on the bed. This can be done manually or with a Z max endstop. G29 S1 can be used after that to load the heightmap.

@user-m_123 have you actually does a successful probing using G29 S0 to generate a height map, before you try to save it using G29 S2?

@dc42 ok
thank you

@user-123 please post your config.g file. It sounds to me that you have configured driver outputs 4 and 5 on your Duet 3 6HC (which I am guessing is what you have - you didn't say) but you are not using them.

@user-123 thanks for feedback and I wish you success in what you plan!
