Can't change my temperature....sort of

[Sonitrolio]

OK....so I have had the printer (Rostock Max V2) for about 2 years...and it's been printing fine. I print almost exclusively ABS, but I got some PLA and wanted to play around with it. I changed the settings in MatterControl and saved them as a preset and started printing, I noticed that the temperature of the bed and the nozzle were still the same as before I changed them. I stopped the print and checked my settings....the settings looked good...I rebooted the printer and restarted MatterControl to no avail. The printer won't go to the new temperatures. I can force the printer to go to the settings I want either by using the screen on the front of it, or by manually typing in the values in MatterControl Target box...but as soon as I click print the temps change to 220 and 70. Does anyone have any experience with this? Hopefully I am just missing something when I change settings. Also I switched back to ABS and am printing some test cubes in the screenshots.

Your first screenshot is just real-time control for the printer. Those settings will be overridden as soon as they reach any conflicting command in a gcode file.

Your gcode file will be generated by the slicer and your second screenshot shows the settings MatterSlice will use. I initially had crashing problems with it, so I have not used MatterControl much. Others will have to say how you lock in your changes on the slicing settings, but you do need to lock in the settings and if you try to print a file you sliced before you changed the settings, it will use the settings that were in effect when you sliced it.

I know exactly what your problem is. Check under Settings->Printer->Custom G-code. You should see:

Code: Select all

M104 S[temperature]
M190 S[bed_temperature]
M109 S[temperature]
G28

But my guess is you see hard coded temperature values instead of the variables in brackets.

I had the same problem and the Matter Hacker team said that older presets had this flaw. Just change to the code above and it should work.

Super rapid reply....thank you. I will change it in the morning when my current print stops. Thank you very much.

That fixed it. Forums to the rescue. Much appreciated.
