bed and extruder temp will not change AT ALL

hello, i have been trying to print however the temperature keep getting set to numbers that are way to high for my filament. i have changed the slicer configuration, changed in in config -> printer settings, even changing the temperature while its heating up with manual control. but nothing works, im stumped and tired of stopping a print after hours because it got messed up or looked bad. please help as i don't wand to waste more filament on garbage.

  • So set values are too high if I understand you right. These are set by the slicer so only the slicer settings are relevant. Save slicer settings and in host make sure to select the filament profiles with the correct temperature and slice. Without reslicing nothing will change of course.

    Afterwards open g-code editor and search for M104 and M140 to verify they contain your temperatures. If they do print should also use them, except you have set some offsets for temperature in host (or server if you are printing over  Repetier-Server ). In server there was a bug in offset so make sure in that case to have latest release 1.4.1 so it is sure yo do not suffer that issue.

    hello, i am not quite sure what you are saying to do. im not that good with 3D printers so i cant mess around with the G code without fear of messing something up, i am also using an old version of repetier host (~2018) and afraid to update because we had difficulties setting everything up and calibrating and we don't want to do it again, i am incredibly sorry if this complicates this. also, i explained my problem poorly in my original post, this is the full problem:

    when i start the print, even if all the temperature settings i can find are set to the correct temperatures for my filament (PLA) and everything is saved as those temperatures, it goes up to the wrong temperatures and even shows the wrong ones on the manual controller and on the physical LCD screen on my printer.
  • The issue is that the set temperature of extruder only gets changed by M109 and M104. So if printer suddenly changes target temperatures such a command must have been send. Hence my suggestion to search for them in the created g-code to be sure they are not in the code you send.

    Now if we assume they are all ok, where should it come from. We normally do not add temperature changes so if it does not come from you or some scripts added and with 2018 I assume you also have no  Repetier-Server running for printing? - it is hard to say. I suggest activating logging and when it happens check the log file around that time. You see in M105 responses set temperature after the /  compared to active temperature. Question is if set temperature also gets up and what got send to set it higher. When you see it in log the source might be easier to locate.
