Automatic Bed Tilt Calibration, G30 S4, and G30 S-2

BStump

@jay_s_uk the M401 looks like it just runs the deployprobe.g routine which in turn runs a M280 P7 S10

; deployprobe.g
; called to deploy a physical Z probe
M280 P7 S10  ; deploy BLTouch

Not quite sure what the net difference is between the M280 P7 S60 and a M280 P7 S10 commands.

jay_s_uk

@bstump normally one is deploy and the other is retract. what type of probe do you have?

@fcwilt Yes it looks like it homes where is currently is on the bed

That is not a good idea - it needs to be the same point every time G30 is used for homing Z or setting the Z=0 datum.

I will have to see if it is used as a subroutine in any other macro. If so I will have to resolve that and if not I can add a move to the back left where homeall.g goes.

Can we set the Z=0 for each Z Stepper, better still for the mean of the 4 steppers. I hope that is what the G30 S4 is supposed to do.

BLTouch

BStump

@jay_s_uk the H558 commands in both the tilt macro and the config.g are identical. I will comment out the one in my modified macro.

BStump

After commenting out the M558 and M280 in my Tilt Macro the results are better but it does not look like it corrected the Z=0. Maybe I need to run a G30 S-2 K0 to correct the Z=0.

Well the G30 S-2 K0 still errored out and said no tool selected.

Added T0 to the macro (not config.g) and got past the G30 S-2 no tool error, but still no sign the Z=0 is being reset.

I need a way that automatically works to reset the Z=0. Currently no sign the tilt correction is taking nor the Z=0 is being reset correctly.

I tried to use your suggested macro and it errored out

But it does sort of run and the second iteration does look like it compensated for the Z=0

But simple thing like

if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed
   M117 "Homing"
   G28

cause errors

It is like it does not like many commands or expressions

@bstump none of my macro will work for you then. Its for rrf 3.2 and above.
You may want to look at upgrading as its so much easier to accomplish in RRF 3. The latest is RRF 3.3.0

to quote @Phaedrux

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.

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.

We are on 2.05.1. Do we need to implement that first file? Looks to be the current RRF.
