yes…

does anyone have any idea what could be?

Are you certain that you have connected your PT100 to the first input channel and not the second? Try X201 in your M305 command instead of X200.

Also if you have a ribbon cable from a PanelDue plugged into the SD_CONN connector, try disconnecting it.

I solved it by placing more double wires, now works fine. I only have a problem when I hand printing the extruder is too far from the plate.

after running the g30 it goes down and stays away from the extruder and when printing the non-return to zero … how do I fix?

Dracula36

hi, I have a problem with g32 after running it I will lower the level of 5mm and of the press away from the nozzle … how can I fix this? I not really understand where I'm wrong

dc42

Sounds like you haven't set your Z probe trigger height. It's the Z parameter in the G31 command in config.g.

Dracula36

It has been set that value
[c] G31 Z-0.02 P50
[/c]

p50 for a npn probe is correct? When I probe with G30 S-1 it works well … with G32 instead of the dish does not rise up to the nozzle ... as I installed firmware 1.18 beta 1 could be the problem?

dc42

If you have an inductive probe then Z-0.02 in your G31 command is definitely not correct. You need to put in whatever height the probe triggers at in the Z parameter. The P parameter is much less important, but P100 or lower gives you the fastest response and on debouncing.

Dracula36

I'm sorry that I have to put in value g31 z ??

https://miscsolutions.wordpress.com/mini-height-sensor-board/ has quite good explanation. It is for IR probe but search for g30 s-1 and around there is the process to figure out Z for g31 described.

Z parameter tells for g31 at what height the probe triggers. Because it is not going to trigger at 0 and not at -0.02 as you have currently defined.
