Config for the Pinda v2 ,need help!

[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
