@Phaedrux I found my problem. My tool fan was connect on the wrong connector.

@phaedrux I restart the card and now it's working.

@Phaedrux I fix the fan and now it's working. Thank

@droftarts, the Z: low end Z probeERROR: pin 'fan1' is not free line look weird to me

I add the EZABL sensor on my printer. I can home the machine but as soon that I try to run the mesh compensation it won't work, I define the area and when it go to the first point it crash into the bed. Here is my config. Any tips?

@phaedrux I restart the card and now it's working.

I do the update from 2.X to 3.0 without a problem. I start the update from 3.0 to 3.4.1 and now I'm not able to connect via my browser. Did I need to remove the SD and modify the WIFI setting into the config file?

@alankilian thanks for the explication it's now more clear.

@Phaedrux yes I seen it I don't understand the R value the minimum and maximum permitted measured movement as a percentage of commanded movement. As the example calibration reports 43% to 115% then you might choose R30:130.

Why it choose R30:130 with the reports of 43% to 115%?

Hi I just installed my laser sensor and I don't now what I should for the ''R" value. here is my result.

Thanks

@jay_s_uk thanks. I ask this question because when I home my Z axis it isn't very constant with my limit switch. Do you have a tip to be more constant like speed, proximity switch instead of limit switch?

Can we configuring stall detection for the Z axis?
