what speed does this looks to be printing?

settings are

Print - 300mm
Travel - 300mm
First Layer - 20mm
Outer Perimeter - 150mm
Inner Perimeter - 200mm
Infill - 300mm
Skin infill - 150mm

the print seems reasonable except the first 5mm and first layer warping a bit, bed temp was 68c, may try 75c, usually print at 80c + bed temp and have no lift at all, actually very hard to remove the part even after cooling down to 30c
20% infill 0.8mm wall and top/bottom thickness
Fluorescent Orange PLA
layer height 0.05mm nozzle temp 230c

running Marlin 1.1.0 rc6

Testing Speed

20mm cube? What acceleration and jerk do you use? You'd need an acceleration of around 5000 mm/s2 to hit 300mm/s on a 20mm segment from standing.

[prusaprinters.org] has a nice acceleration/speed chart

Great print! Pretty amazing for that speed

+1 For JamesK, default acceleration is 3000 mm/s^2, you might actually be printing at 240 mm/s on the longest edges, but that's not bad at all!
Also, make sure your slicer doesn't have a maximum flow (repetier is 12mm^3/s by default) so it reduce the actual feed.

Thanks for the reply, before I start the print I did change acceleration in marlin to 5000 max and max flow 20. But even if that was only doing 240 is still much better than the usual 60 to 80 for an i3. I do a bit more playing around again next week and see what's the fastest I can go, it's more so at smaller layer height I want to be able to increase the speed so the print time doesn't go through the roof, the smallest I've manage so far was 0.03mm with successful print, I did managed 1 very small print at 0.01mm but the Base of the part wasn't as good as 0.03mm. I'm using 10mm leadscrew on my Z axis with 2mm pitch.

It's pretty impressive. I've never had any luck with either such high speeds or such small layers.

its nice to reduce print time on small layers, was just playing around for a bit of hope and turns out fairly ok

playing with ABS now but highly doubtful to do anything high speed with that

but printed very well
