duet2, firmware 3 --> bed and 1 heater on TEVO little monster

deckingman

@RafB prior to RRF3, H0 was by default, the bed heater. Since RRF 3, it is not and you have to explicitly define it using M140 H0. Are you sure that you put that command in your config.g and saved it? BTW that's H zero not the letter "O".

Thank you for your help.
Droftarts, I forgot to uncomment the tools, it works...

I have a new problem that I don't understand at the moment.
After a home, I get this message

Post your homing files.

How are you homing when that message happens? From the DWC? Sending G28 in a gcode file?

Can you evoke it again by sending those lines from homedelta manually in the console?

Hey, guys,

I'm doing a G28 and then I want to put my head down, that's when the message comes.

When I send a gcode file with G28, it works perfectly.

What do you mean by "I want to put my head down,"?

If you press the homeall button in the DWC does it work without error?

Okay, I just figured it out and everything seems to be working fine.

I was trying to shoot my hothead but I pressed +0.5mm and when I pressed -0.5mm I got the same message.
On the other hand if I do Home(G28) and I press -0.5mm my hothead goes down correctly.

Sorry, rookie mistake...

Glad you figured it out.

I wanted to run a print but I still have to put G31 Zx.xx (0.88mm).
I don't understand the difference between Firmware 2 and 3.

Can you advise me on this point here? J'ajoute simplement la ligne à Z-probe?
G31 Z0.88

Actuel z-probe
; Z-Probe
M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H6 F200 T2000 ; set Z probe type to bltouch and the dive height + speeds
M557 R150 S20

There is no example in the firmware3 wiki. Complicated for a beginner like me

@RafB Refer to the main gcode dictionary: https://duet3d.dozuki.com/Wiki/Gcode#Section_G31_Set_or_Report_Current_Probe_status

Put it in your config.g. eg

; Z-Probe
 M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H6 F200 T2000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z0.88                            ; set Z probe trigger value, offset and trigger height
M557 R150 S20

This is where you put your probe XY offset, too. You can use the RRF config tool to produce example code: https://configtool.reprapfirmware.org/

@droftarts Thanks a lot!

I would like to know if it is possible to change the shrinkage values during printing?

droftarts

@RafB You can use https://duet3d.dozuki.com/Wiki/Gcode#Section_M579_Scale_Cartesian_axes for scaling. However, I don't know the effect of doing this during a print.
