M143 H1 S285 ; Set temperature limit for heater 1 to 285C

this limits your max temperature to 285

just do the thing i the guide for now

M303 H1 S240 ; auto tune heater 1, default PWM, 240C target or maximum temperature

M303 ; report the auto-tune status or last result

and save with M500

Can i now just chainge the max temp in M143
To a max of 400C after the auto tune

@ziggymanpopo looks like you were successful, but you do need to add M501 to the end of your config.g file so that those parameters in your config-override actually get loaded.

On what temperature to run it at, generally you want to do it at about the temperature you are most likely to print at. If you tune for 400C but only print at 200C, it will work, but maybe less accurate/stable and might overshoot the demand a bit.

The bigger influence will be your print cooling fan. I think the guide mentions it. You should run your fan (at least one part power) during the tuning process if you're going to use it during printing. That way it can (partially) account for the cooling affect on the heater block

this might surprize you but where and what do i put in the file just M501
not sure i understand

; Tools
M563 P0 D0 H1 ; Define tool 0
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C

; Automatic saving after power loss is not enabled
; Custom settings are not configured
; Enable Bed Leveling
;G29 S1 ;commented out Enable Mesh Bed Leveling

this is the end of config g....Why would this stuff be commented out

@ziggymanpopo literally just open up config.g via the Duet Web Control to edit. Best place to put it is right at the end (you may find thenline is already there but commented out).
Then save and it will ask you to reboot the Duet so it can reload the updated config

Save it is M500??

N m figuared it out 🤪
