I've been playing with draft quality print speed settings for PLA and get little noticeable quality difference with these settings relative to 100 mm/s and slightly smaller percentages. First layer speed is 60% and x & y acceleration is 2000.



Also, I can print PETG at 100 mm/s..

Any reason I shouldn't be printing at these speeds when time is of the essence?

PETG at 100 is ambitious. Especially if you have any increased infill width. Filament will be very likely to strip out in fast long runs.

I'll watch out for that, thanks. I haven't tested much high speed printing with PETG as I usually don't have a need to go fast with it. It's convenient to rip PLA prototypes out quickly sometimes though.

I would be curious to know if the rambo can actually process and print at 200mm or if it hits a buffer head at some point and you really are printing at 100 ? The two things I have noticed since my board swap are that 32 micro stepping helps with better dimensional accuracy and lower noise . And 60mms seems more like 125mms. This is just purely observational though as I have not tested this what so ever .

Ya I have no idea but can't it rapid traverse at 300 mm/s? If thats the case it would seem like it could print at that speed but I don't know.

One or ten moves all day long I would guess. But at those speeds with thousands of lines of gcode my guess would be a slow down would happen as the board might not be able to keep up over a long print. Just a guess though.

Should not be hard to test. Just change the speed setting and observe the resulting change in your projected print time.

If you have S3D, which is a notoriously inaccurate timekeeper, you should actually print the item at both speeds and see if the theory has some teeth.

I think the opposite of a "New York Minute" is the "Simplify 3D minute".

I do hate the inaccuracy of the S3D time estimate.

Oh man we all do.... need to try playing around with that time estimator again that jsc was working on... it was so much more accurate.
