Welcome to the SeeMeCNC Community

Hi,
I am setting the temperature of the bed and nozzle in MatterControl and exporting these settings to my SD card.
However, when I put in the card and select the print, the printer defaults to 220/80 instead of what I chose from my computer.
Is the simply unable to read these settings from the SD card or did I miss something when exporting?

The temperature settings should be adjusted within the slicer settings and exported as part of the gcode.

Post the gcode file that is on your SD card.

Huh, never thought of going straight into the code to make these changes.

You don't. You properly configure the slicer you're using.

I'm changing the temperature in the Filament-filament settings to 180/60. When I plug in the SD card and choose the file it defaults to 220/80. Not sure why.

Here is what I do for a new material. go to advance settings >settings tab>click the pencil icon next to the material drop down selection> click edit on one of the presets that closely matches what your after> at the bottom click "Duplicate"> at the top give it a name(one that lets you know what make, type, and color it is)> make the changes you need >save> then use the material drop down list to select your new pre-set.

when you export the g code, it should take the temp/print settings info from the pre-set.

Yes, this is what I have done for everything. I have already preset diameters, temperatures, and extrusion multipliers for all the different colors and materials I have. But recently, and not only through the SD card (as I have recently tested), even if I have the presets for 180/60 it still heats to 220/80 when I submit the print. I have even tried preheating to 180/60, but still it heats to 220/80. Lastly, I have used the dial knob to manually change the temperature to 180/60 and it does. However, when the print actually starts, it immediately changes to 220/60. For whatever reason it only changes the nozzle temperature at this time.

Additionally, I have noticed it has been printing extremely quickly. I've manually lowered the speed to 33% just to maintain the speed I had it going in the past. I haven't changed any settings; it's been acting up recently. My infill and outside perimeters are no more than 50, but I swear this thing is moving at 150+. MatterControl says prints should take about 5 hours, but I come back to check on it after an hour and a half and it's already done with very ugly looking perimeters.

Right now I have a 17 minute print that finished in a few minutes. Needless to say it looks atrocious.

Is there like a reset I can do or something? This is freaking me out.

So either the slicer is generating bad gcode or the machine is executing it incorrectly.

Try downloading a different slicing program and use it to create a new gcode file. KISSlicer is one that I like.
If the printer behaves as it should for speeds and temperatures using code produced by a different program, you can safely say that your Matter Control installation or settings are the cause of the trouble.

If you get similar poor behavior/results from the alternate gcode file, then the problem is in the printer and you'd want to reinstall the firmware.

Thanks for the advice. I ended up updating MatterControl and resetting all the settings. It's behaving now. I was worried some wires were interfering with each other or something for it to be jerking around so quickly, but it seems either a corrupted or out of date MatterControl was the issue. I will try out some other slicers to get the hang of things better.

I am glad that you figured it out. Great job!
