Nice, look like around 100 mm/s if not mistaken. I was wondering about the core XY progress.
I guess the hotend is running at 220+ DegC.
Today I tried PETG and I really like it since it came out as expected.
First print worked out well, just have some corner warping issues. The material is surprisingly really flexible.
If I would recommend a material I would suggest PETG for strong and resilient prints.
Drillz of first print and believe me the setup didn't take long since it is like printing with PLA and ABS combined.
I think it was 120mm/s. It was already slightly underextruding at the infill , the hobbed filament gear wasn't really good and begin to grind the filament. Probably need to look at thingiverse for some good bowden setup with a hobbed filament gear.
Progress is slow, trying to perfect the hardware, I've made 3 iteration, first it was direct drive, but it was taking up so much space that I was losing quite a bit of travel length. Then I tried to come up with some ways that the setup could be more space efficient with the direct drive method but wasn't really successful. So I went for a bowden setup at the end. Will try to make the gantry smaller after this so that it is more compact.
Yup PETG is good, I'm surprise the adoption isn't any faster, so much easier to work with, and don't really like the idea of breathing toxic fumes from printing ABS.
