I'm on windows version 4.8 and for me it is in .

Extensions > post processing > modify g code > add a script > pause at height , and may be set method to reprap m226 .

@fadi I would say buy a cheap kit first like the ender 3.
Which is like a build your own , but it as all the correct parts and instructions how to build it.
Play and learn with all the parts and find why some parts are better than others , take things apart and learn before you make your own .
I started my 3d printing days with my own design , but it is not until you get it working you find , "you think you are making a great new design" , but really building a cart with square wheels.

@o_lampe

Over the first post there is a topic tools gear button ( Right , Top ) .
Select ask a question, then select topic solved .

@alxndr ok let say you want to probe 50 from each corner ?.
M557 Start x : End x Start y : End Y S steps
M557 X50:170 Y50:170 Which works out to be 30 spacing
So M557 X50:170 Y50:170 S30 will probe between 50 and 170 inc.

@tinken on cura there is .
there is a pause at layer height

yes your logic is correct of S55 is correct BUT DON'T FORGET , 0 and 220 is first and last points where the probe will check the bed, So the nozzle will be 45mm off the edge right side of the bed ?. ( don't know if this is a problem or not )
So you may only be able to probe 130mm of the bed.

0+45 and 220-45 ?

not sure about the R value never used it myself , it is a delay before after probe.

@droftarts said in Firmware update duet 2 , 3.11 > 3.22:

M997 S1

Done that , it look like it as stop my wifi , eg wifi is disconnected .

o.k restarted my wifi with M552 S1

back up and running .

@Phaedrux

Not seen sykb on , But I can see lots of faults .
Can't tell what printer he has , but to me the off sets or wrong , the homing files are wrong , and he is not probing the centre of the bed.

@alxndr said in Duet 2 Wifi + BLtouch issues on Ender 5 pro:

; Z-Probe
M558 P9 C"^zprobe.in" H5 F100 T2000 ;
M950 S0 C"exp.heater3" ; define GPIO/Servo pin index
M557 X0:220 Y0:220 S25 ; define mesh grid
G31 X-45 Y-4 Z3.737 ;
M307 H3 A-1 C-1 D-1 ;

G31 X-45 Y-4 Z3.737 this should set it offset to 3.737mm from the trigger point of the probe to the bed, I never bothered with G92 Z0.

Too many points M557 X0:220 Y0:220 S25 , the S25 is the spacing between point so just increase the S value .

Just use m401 and m402 to test if the probe retracts .

Also m558 :- Rnnn Z probe recovery time before the probing move is started.

@Phaedrux I was using heater 7 before on rrf 2 , so moved the control pin to heater 7 and it works.

@k0s Soon I can let you know how to do it because I'm going to install 3 neopixel rings and a strip on my standalone duet 3 mini 5+.
Having problem calibrating my cube so being delayed a little moving on to installing neoplxels.

@k0s Look for a BLV MGN CUBE which uses 3 neopixel ring , so that should give you a clue how to set it up. ( it look like they don't use the neopixel pin too )

And this is how to control them with g coded .
https://duet3d.dozuki.com/Wiki/Gcode#Section_M150_Set_LED_colours

@k0s Do you want to control them with a program running on the Pi , but using the neopixel pin on the duet 3 mini 5 + , or have to pin on the PI ?

@k0s If I remember right you can't control neopixels from the raspberry pi due to timing demands of neopixels with the operating system , you can control them from a multitasking OS like Linux .

Hi , I have a set of heater bed cooling fans which in my cura end gcode I've added M106 P2 S1 H0 T30 .
AND added M106 P2 S0 H-1 at the start of my cura start code, BUT you problem is this get executed after the bed and nozzle has reached temperature , so fans are on until the temperature reached and then switch off .

Is there a macro which gets called first ?

@eengineer it should be in your config.g file

G90 ; send absolute coordinates.
M83 ; but relative extruder moves.

but you have to tell the slicer to use relative extruder too.

in cura it is in special modes

@eengineer

if you set it to -2mm so it grip the paper how close is it to hitting the retracted probe ?

I can see now your bltouch is closer to the bed when it touches than mine, but your -2.1mm says not.

something is wrong I can't work it out !!!

@eengineer said in Z offset resets on every print or Homing and start gcode asking:

The Z offset between the nozzle and BLTouch is at about 3mm

Not sure what you mean , is that on the screen or the distance between the nozzle and the bed which you have measured AND 3mm when ?

just thinking I'm wrong the probe to too few down !!!!

@eengineer

Have you any adjustment on the bltouch to move it down ?

Wow -2.1mm that must mean that the nozzle is almost hitting the bed when the probe retracts ?

@eengineer What would do and how I do mine is :

Change your G31 P25 X-29.75 Y-14.50 Z2.2 and reduces the Z offset by say 0.5mm ( or more ) Z 1.7 and babystep down until it grips the paper , which it should just touch at 0.1mm and grip hard at zero.
Now if it grips the paper at 0.3mm just increase Z offset value by 0.2mm and try again.

YOU NEED TO LOWER THE G31 Z value and reboot.
