@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.
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.
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.
@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 .
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
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 !!!
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 !!!!
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.
