2000 degrees after restoring config

@craigrezac7 said in 2000 degrees after restoring config:

; homeall.g
G1 H1 Z305 F360 ; move Z up stopping at the endstop

; homez.g
G1 H1 Z305 F1800 ; move Z up until the endstop is triggered

It's these two lines, which are moving the bed to maximum Z, which is down. The 'up' comment is confusing, because the config tool is assuming the X axis moves up, not the bed moving down. What it does is increase the distance between nozzle and bed, which is a positive Z movement. What you want is a negative Z movement, to bring the bed and nozzle closer together. Change both to G1 H1 Z-305 F360. The feed rate 'F' doesn't matter too much, as your Z axis is probably limited to 3mm/s, or 180mm/min, which is F180.

Also, I think you need to change the Z endstop definition again. You did have:

M574 Z2 S1 P"!zstop" ; configure active-high endstop for high end on Z via pin !zstop

The 'Z2' is for a 'max' endstop, ie bed furthest from nozzle, so bed moves down. Again the 'high end' comment is somewhat confusing, assuming it's the X axis that is moving up, not the bed moving down, so this should be Z1. I mentioned that you inverted the endstop with '!' earlier, which changes the behaviour of the endstop to report 'not stopped' when pressed, and 'at min stop' when not pressed. Did you change this? Change this to M574 Z1 S1 P"zstop".

Before homing, test your endstop by sending M119. With the Z axis not activating the endstop, it should say 'Z: not stopped'. Then press and hold the Z endstop, and send M119. Should then say 'Z: at min stop'.

@droftarts I did switch that ! after you mentioned it last time. I am horrible with coding. That did fix the issue though, the -305. Thank you very much. That makes perfect sense now that you say it.

Hey,

I have the same issue with my board.
Installed 3.0 and changed 308/950 comands as per example.
Both sensors shows 2000C

Am I missing something?

Best to start a new thread with some more details about your setup. Include your config, and how you have everything wired.
