Looking for a little guidance. Purchased X1C new several months ago. Have printed PLA. Prints have been smaller in size. When printing larger items. The finish on the final couple of layers is bad. Have tried tramming the bed with a .4 mm feeler gauge. But continue to get unsatisfactory finish on larger items.
Any help you can give would be appreciated
Good morning.
Although I do not position myself as an expert, if it is PLA, looking at the surface it is possible that the part has moved as it cools.
This happened to me and I increased the temperature of the initial heating bed from 35°C to 45°C or even 50°C.
Mine also does these on large surfaces I don’t think is a bed issue, because I can change the print speed to silent if it starts to do this and it immediately goes back to being smooth. I think it has to do with chatter from the rails. A combination speed and vibration. I have yet to track down where the harmonics are coming from though.
My printer sits atop about a 200lb wood dresser over a carpeted floor. There’s like zero shake and the thing rips out prints like there’s no tomorrow. I had some single layer prints that had gaps in one area of the bed. After cleaning the plate with alcohol, prints from then on were perfect. Don’t touch the printing area of the plates. I also run my bed temperature at 60-65c for PLA on PEI plates (no glue).
It looks like the bad parts didn’t stay stuck down to the bed, possibly curling up, and causing the print head to brush up into them, resulting is the mess you have on display.
Thanks so much for everyone’s advice. I will give that a try….
