Under extrusion.
First print was great. Then I got the extruder clicking and It jammed. I cleared it all out and Did one more print. That one came out meh.
Then It just stopped working. This is a assembled mini plus.
Printer just came 4 days ago. I've owned an mk3 since it came out. I CANNOT GET THIS THING TO PRINT. I have tried everything that I can think of. I've taken apart the extruder, checked everything over, all was good in there. I have taken apart the hotend and replaced the ptfe tube. Made sure I did all steps that were stated in the instructional pictures and others videos on youtube. Made sure that there was not a gap between the hotend and ptfe.
After the first layer and sometimes even on the first layer I am getting uneven extrusion. Once the printer starts to do its quick movements, everything goes down hill and I have to cancel the print. I'm lost. There doesn't seem to be anything left to check.
Hot end holds its temps
First layer is laying perfect when It extrudes correctly.
Gears look good
Ptfe tubes {all look good}
This is happening with prusament signal white and galaxy silver. Only 2 I have.
RE: Under extrusion.
I had the same issue and I was able to get some much better results by upping the temp to 233c and adjusting the flow factor to 100. I did notice that I had to do this twice as the temps seem to reset to the defaults after the first layer. I'm working with 2 days of experience, so this may not be the best idea, but it's working for now till I figure out what is going on.
RE: Under extrusion.
In your prusa slicer settings there are temperature setting for both filament and bed for First layer and subsequent layers. So its no surprise that it set to the values contained in the gcode when it went to the second layer.
You are better off modifying the filament profile, saving it with a suitable name and re-slicing with the temperatures you actually want to use once you have values that work for your particular combination of machine and filament. For example my mk3 is fitted with a steel nozzle-x. That requires temps to be increased 5c generally so I have my own filament profiles with this change saved.
