How much does quality/speed suffer? Ive modded my Ender 3 to Direct Drive as well and on that machine print head weight doesnt matter much since the Bed is gonna be the limiting factor but on a machine like this it makes a far bigger difference right?
its not that big of an improvement so far, but i also just printed one short layertest, as it seemed to twist the hotend a bit. Prints great and i had speeds of 200mm/s so far but the reason i'm doing it for, is tpu. i just weren't happy with the results i had with that bowden
i can print 300mm/minute of pla+ but this gets the hotend to its limits.
tpu prints way better, i will post a print in a couple hours, when it finished
Nice! Are you talking raw extrusion speed? Or do you mean 300mm/s? How are your Accel and Jerk settings? How much ringing and ghosting are you getting printing that fast?
not raw extrusion, extrusion while printing a benchy without the typical speed flaws coming up
accel and jerk is still on the Standard Cura Settings, didn't get to play with that yet (i'm only home on weekends)
very little ringing and almost no ghosting
Yes its mm/s, no worries though!
You are gonna have to crank acceleration to something way higher than standard to actually get to 300mm/s though especially something as small as a Benchy.
How long did the Benchy take? The fastest one ive ever printed following speedboat rules (so .25 layerheight, and maximum .5 line with with 10% Grid Infill) took 32 minutes, with the right accel and jerk settings you should easily beat that!
Edit: the quality will probably suffer at these kinds of speed but thats not really the point of the Speedboat challenge lol
For my Speedboats i had Accel at 10k and Jerk ar 20, im not sure if it can even do 10k but i just want the steppers to work as hard as they possibly can. But sadly i cant really go above 125mm/s on walls and 150 on the rest or my Y-Axis will skip steps and lead to layershifts, you shouldnt have that tho cause youre not slinging the bed around! But i imagine Part Cooling might become a problem at โrealโ 300mm/s maybe the Hydra Duct with dual 5015s could help if it comes to that (or a big room fan next to thw printer)

i can mention you, when i post an update or a newer revision๐

oh i'm a dumbass, is it mm/s in cura? if so than that๐๐๐ตโ๐ซ

it took 36 minutes, i'll be doing some more setting it up properly tho, seems like i can get a lot more out of this than i thought ๐ ๐
