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.

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.
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.
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.
In my case, although I set the bed temp in Prusa Slicer to be 65C, it ignores it and goes to 115C on multiple different prints. See my Prusa Slicer Code and note that the temperature is correctly set:
So as you can see it's not the the slicing. What I noticed to be different, is that when you change the temp after the print has started (I am using Repetier Server), it looks that it is not changing the target temp, but it actually does, but by the time you see it dropping significantly, the 2nd layer starts and then the temp is reset to 115C.
If you manually change the value on the server platform enough times it eventually sticks after the 2nd or 3rd layer.
So any ideas?
Many thanks for your time !!
Otherwise if this is already zero activate logging and check when it gets send wrong to see where it comes from.
If I may say this is a silly setting to have as default though. Now I set it to 0C and I will have another go. I'll keep you posted!
