ReMan

Hi Hendr1x, I just saw your original post as I was searching for a solution to probably the exact same issue on my machine. I ruled out machine mechanical issues and slicer settings first. Then I took out the SD card and swapped it with a backup that I had on-hand. The next print is printing exactly as it should - no stuttering or slowing to a crawl at some points. But then on the next print the same problem occurred again. This time I noticed that other little problems are happening at the same time. The temperature does not always register correctly on the screen. The print head carriage will slam into the limit switch and also on the other end of the x-axis gantry and make a terrible noise when doing so. The print head crashed into the print bed for no apparent reason while auto leveling. I believe the main flex/ribbon cable to the print head (Sprite Pro direct drive extruder) was hitting against the frame on the left hand side so much that it either broke some of the wires inside or else caused the connector to come part way off the extruder. After straightening out the cable and re-securing it, all of those problems disappeared. Hope my experience can help you.

I guess it's another firmware issue - I have run into several of those on this machine and find that firmware is the biggest issue I have in my 6 months into this hobby. I am learning to recognize when it might be firmware related now, since I have already upgraded nearly the whole machine with new hardware while trying to solve so many other issues. Hope my experience can help you.
