RepRapFirmware for Duet 3 Mini 5+ version 3.3 (2021-06-15 21:46:11) running on Duet 3 Mini5plus WiFi (standalone mode)
Board ID: MZSV6-S096U-D65J0-40KMD-3413Z-R7859

Not run my BLV cube ( mini v3 x 5 )for a while because I broke a part holding the cables, So today was print that part and get it back on the road again .
Fixed the printer easy, but the Z-offset was off , so it was do a height map and see what's up .
Booted and got a you are missing the config.g and config.bak , so doing a run mash calibration just deleted my config.g file , not happy , BUT LUCKY ME a made a old copy of the config.g .
Back to working , but this should not really happen ?.

@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 .

@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.

@eengineer and the Z-offset changes back to some other value

Does it show a different value on the screen or are you guessing ?

in the air well above the bed and in DWC it says its on Z0.3 on first layer.

Have you tried a homing paper test ?

Which is in the centre of the bed , home and baby step down until a bit of paper grips the nozzle .
if it doesn't grip the paper than you need the change the offset in G31

@eengineer I'm a little lost what you are asking ?.

You have a bltouch which should set the same z offset with a differing bed height etc , so if you rehome you should get the same offset from the nozzle to the bed.
BUT you will find that using baby-stepping you can 't go lower that zero Z.

@kb58 one for you macro list reset bltouch M280 P0 S160
then rehome which should drop the bed 5mm or so before the probe.

@dc42 E-mail sent !!!!

@dc42 at this time you just can't get the Mini 2+ in the UK , will you be ever selling them direct .
At this time you can get From Filafarm Germany https://www.filafarm.de/collections/elektronik/products/duet-3-mini-2-dual-stepper-expansion-board
But the postage is as most as the board !!!

@davidewen Yes , mine is in the same direction on both motors .
But you still may need to swap motors .

@davidewen True , but you are also changing X , Y to Y , X
I don't mean change the wires of each motor , but swap left to right motor.

@davidewen Homeall.g is crazy but it still should home in the right direction .

Have you tried swapping the x , y stepper motors wires and tried the 4 motor possibilities ?
