Printer prints nice first layer but later get issues
Hello everyone,
I have a strange issue and do not know where to start the troubleshooting. I have a DIY MK3 with the Firmware Version of 3.4.2
When I print for example the Prusa Bottle opener from the SD Card the first layer looks pretty decent but around the 4th layer on some points underextrusion seems to happen. I am using Colorfabb Yellow PLA. I also attached pictures of this and hope that maybe someone can point me into the right direction to troubleshoot this.
Best Regards

Slow down the print. Most likely used filament can't do this speed.

What did you try yourself?
Give as much as possible info, you give almost nothing!!!!
Temperature you did print?
Temperature needed by the filament?
Try different temperatures, 5 or 10 higher to test?
Try different brand filament?
Do manual extrusion, comes the filament straight out of the nozzle?
Does the extruder slips sometimes?
Do a cold pull, to clean the nozzle, do this 3 times if you think it is clogged, heat the nozzle to 190, then do a unload of filament, do this several times if needed, because it is cold 190, it pull the nozzle clean, see how the point looks, it should look like the nozzle inside.
Slow down could help. Infill is high speed 180 200, adjust this. Or slow down the whole printer.
