Cartrage change



  • Well now that ive read up on everything i could find on how to set up my P.I.D Im at a total loss as to the process.. any hints on where to find step by step instructions would be cool 😜

    Specs.
    Removed... 30watt cartrage
    Instaled..... slice engineering 50w 12v cartrage

    Will the duet board handle the load ???

    Duet wifi2 ver 1.21.



  • @ziggymanpopo said in Cartrage change:

    12v cartrage

    is you power supply also 12v? this is very important.

    Duet wifi2 ver 1.21.

    that version is very old, you should consider upgrading.

    Well now that ive read up on everything i could find on how to set up my P.I.D

    can you be more specific as to which part of this documentation you do not understand?

  • Yes 12 v suppy and i am not sure about how to set it does the reprap software run the heater up to temp and remeber the curve after
    Does the max temp i plan on using come into the pid settings.
    Do i run my heat up to say 230 c. (petg )
    Or up to 400 c.



  • ; Heaters
    M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0
    M143 H0 S120 ; Set temperature limit for heater 0 to 80C
    M305 P1 x501 R4700 ; Set thermistor + ADC parameters for heater 1
    M143 H1 S285 ; Set temperature limit for heater 1 to 285C

    ; M307 H1 A245.3, C121.7, D4.0, S0.5 ; PID

    this might help



  • The big question i have is what temp do i run it up to when i do my thing here.
    I have a mosquito mega hotend that im instaling.
    The link you gave me had an other link1 to what i was missing so thats the last item on my mind
    How hot to run the temp comand
    And i would change that in the M303 comand?

    Than M500 to save it. ????



  • @ziggymanpopo said in Cartrage change:

    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

    im assumig i was sucsesull??? thasks veti



  • @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 ðŸĪŠ



  • Thank you 😁👍
