smart effector g32 issues

sankafola

hello,
i have Duet 3 SBC setup and i installed smart effector , i do the the G30 the nozzle goes down and touch the bed and go up and works fine , when i start auto calibration in my delta Anycubic , the nozzle crash on the bed and drag the nozzle ,

my M665 R227 L440.43 B185 H404.22
please help

post your entire config and config overwrite

@sankafola I would increase the dive height in your first probe. That's the 'H' value in M558. Use something like 30

@jay_s_uk thanks that worked

dc42

Once you have corrected your M665 and M666 values following auto calibration, you can reset the dive height to a lower value such as 5mm.

@dc42 can you please help , i have SKR 1.4 turbo and i installed the Rerap 3 on it with SBC raspberry pi , and smart effector and magballs , i have connected the wires to the servo GND power 5v , and the output Z , the smart effector do the 2 flashes and do the probing and all is fine except when i print i have to do baby step + 0.8 , what am doing wrong do i need to put the mod pin and if yes where ? and how do i fix this babastep + 0.80 for good ?

jay_s_uk

@dc42 just to verify, currently he has the mod pin not connected.
When setting the probe so its G31 settings are G31 P100 X0 Y0 Z-0.1, as is typical for the smart effector, 0.8mm of baby stepping is required to obtain a first layer.
If the G31 is modified to G31 P100 X0 Y0 Z-0.75, 0.8mm of baby stepping is still required to obtain a first layer.

any thoughts?

dc42

The Smart Effector mod pin can be left disconnected if the default sensitivity is working.

Z-0.75 is not usual, unless the bed or the delta mechanics are very soft. I suspect that either auto calibration has not been run, or the results from it have not been saved, or they have been saved in config-override.g but there is no M501 command in config-override.g.

What are the M558 parameters, in particular the probing speed?

sankafola

@dc42 i ran the auto calibrate , the M501 is in the config and uncommented and my M558 is

M558 P8 H2 F1000 T12000 R0.2 S0.02 A5 C"servo0"

sankafola

@dc42 that is my config file

@sankafola said in smart effector g32 issues:

G31 P100 X0 Y0 Z0.1
M558 P8 H2 F1000 T12000 R0.2 S0.02 A5 C"servo0"

see https://duet3d.dozuki.com/Wiki/Gcode#Section_G31_Set_or_Report_Current_Probe_status

A G31 command to set Z probe parameters must come after the M558 command that defines the Z probe.

M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp

4138 is the default and wrong for your thermistor

sankafola

@Veti i have PT1000 thiermster what would be the value because am getting a lot of heater fault too what is the bed value and the hotend please ?/>

Veti

@sankafola

you have a pt1000 on your hotend, but your bed has a thermistor. which thermistor you have i can not tell you. you will have to look that up from the sales information.

sankafola

@Veti found it M308 S0 P"bedtemp" Y"thermistor" T100000 B4300 C0 R4700

sankafola

@dc42 the bed have the whambam with PEX maybe that is why ? what do i need to do ?

jay_s_uk

My machine has whambam PEX and I use the default 0.1 perfectly

sankafola

@jay_s_uk all good now did the procedure again for delta calibration and now seem fine thanks all for the help
