@martin7404

Are you german?
If yes can you explane me in german ?

lui2004

@martin7404
What is the 0?
I use only 3 wire? The temp wire ist not in use?

martin7404

@lui2004 sorry I am Bulgarian .
So generaly you ahve 3 wires +5V,- and Signal.

and Sig are conected to - and sig on probe conector and 5V to some 5V pin on the board

lui2004

@martin7404 like this:

and config:

; PINDA2
;
M558 P5 C"zprobe.in" H1.5 F1000 T12000 A3 ; set Z probe to PINDA2
M308 S2 P"e1temp" A"Pinda V2" Y"thermistor" T100000 B3950 ; temperature of PINDA2

T3P3Tony

@lui2004 that looks correct and the config matches the wiring. As always when you test the trigger for the first time first confirm not is triggering as expected by manually lowering the Z axis so it's not the expected trigger height and checking the z probe is shown as switching in DWC

@t3p3tony

after i do a Dynamic test

the pinda v2 wont stop it will crash into the bed

T3P3Tony

@lui2004 if you move the probe down manually do you see the Zprobe indication on DWC change. What is it showing?

lui2004

@t3p3tony

the pinda wont trigger because i have a pei surface.

i have insert some Aluminum foil under the pei i now it will work.

which surface is good without Aluminum foil under pei ?

T3P3Tony

@lui2004 whats the PEI surface mounted on? I suppose most people using PINDA style probes an aluminium bed.

lui2004

@t3p3tony

aluminium bed with pei

this is my heightmap:

I bought a new surface !

what is important to calibrate the pinda V2 ?

Hi

Is there a how to ,to set z offset on different temperature? Like in marlin?

T3P3Tony

@lui2004 there is not the option of using a table like i think Marlin has. You configure the S and C parameters within G31 to compensate:
https://duet3d.dozuki.com/Wiki/G31

Based on this thread:
https://forum.duet3d.com/topic/16972/pinda-2-probe-with-temperature-compensation/5?_=1593546022132

It appears the non linearity of the measurements at different temperatures could be a problem.

The poster in that post shows a conditional gcode way to get around the problem. Before you do that it would be worth testing you can get a good z probe performance with everything (including the PINDA temperature) at a steady temperature.

Once thats working then non linear temperature compensation can be looked at,

lui2004

@t3p3tony

Thanks ,i will give it a try!

Other question when print is finished my z axis at 0 what i can do that the z-axis goes u after print?

T3P3Tony

@lui2004 in the end gcode you can add a move to lift slightly and move the tool out the way.

E,g,

G91 ; set to relative positioning
G1 Z5 ; raise Z 5 mm
G90 ; set to absolute positioning
G1 X0 Y0 ; park at X0 Y0
