when will the new Z-height actually be saved?

Please post your homeall, homez, bed.g, start.g and your slicer start gcode section so we can see what is happening.

The smart effector has a negative G31 Z offset because it contacts the bed and presses into it. So -0.1 sounds fine, but perhaps you have another command altering it after startup.

The G32 (achrn) dit the trick But what a hassle to sort everything out for a beginner

What is the way to setup Auto calibrating before each print?

jay_s_uk

add G32 to your start gcode

@jay_s_uk

It looks that I don't have a start gcode in my System Directory, or I can't find it

Hi,

They are talking (I think) about the place in S3D where you can enter gcode to be executed before the start of the print.

You can also, if you wish, create "start.g" in your system directory and put gcode there - the firmware executes "start.g" at the start of the print.

I don't know where to find the rest

bed.g

Tomorrow is a new day, I have to go to bed now.

But thanks for all the help

in the /sys folder along with config.g

This all I have in the System Directory

Made a start.g directory with a G32 file in it, but for the rest I am lost Start.G.png

engikeneer

@holco62 he meant create a file called start.g in your duet system directory (/sys folder). In that file, put the line:

G32

To answer your other question on the files, please attach your bed.g and homedelta.g files from the system directory (i can see the file names in the screenshot)

start.g is working, one thing though, it das the calibration with a gold bed/hotend, is there a way to bring up the temps first?

The bed.g and the homedelta.g files

You could add a bed heat up command to the start of your bed.g. something like.

M140 S60 ; set bed to 60 and continue
G28 ; home towers
M116 ; for for tempts to be reached
G30.... etc ; probe for calibration

@holco62 said in when will the new Z-height actually be saved?:

...is there a way to bring up the temps first?

Short answer - yes - @Phaedrux has shown a simple approach.

Long answer - there are several different ways to do all that is needed to start a print.

For example, instead of putting everything in bed.g you leave just the essential commands there (the commands you already have) and put everything else (setting temps, waiting for temps, etc) in start.g including the G32 to invoke bed.g.

As you become more comfortable with the firmware there are lots of things possible.

I'm including my equivalent of "start.g" just to give you an idea of the possibilities BUT I am NOT suggesting that you try to adopt anything I have done at this time.

There are lots of extra ; characters there that I added because {1} appeared at the start of empty lines when I pasted the code

Thanks, I'll see if I can put something together myself.

holco62

I've tried

M109 ; Set Extruder Temperature and Wait

M116 ; Wait for tools

in the start.g file with as last line

G32 ; call bed.g

but when I issue a print command generated by Cura the printer directly starts with G32 and after calibration the bed starts to warm up.

What am I doing wrong?

Have you set a temperature? M109 by itself does nothing. See here for how you would use M109

@Phaedrux
Ok, I was under the impression that the Cura slicer controls the temp
