Hi guys, I have attached a factory file of a 20 mm calibration box
, to be printed with a raft in ABS at 0.25 mm layer height. The Default Printing Speed is set to 50 mm/s, which is supposed to be used for infills if I understand correctly. I find that the first layer after the raft is being printed way too fast. See the attached picture where the first layer after raft is color-coded green, indicating it is printing well above 40-50 mm/s. This is way too fast for the first layer to stick to the raft. On small things like this it is probably fine but on big, circular objects the first layer fails to stick and just gets dragged around by the extruder.
I tried setting the outline & solid infill underspeeds to 25% which should reduce the speeds on these parts to 12.5 mm/s, however this seems to affect only the subsequent layers of the object (color-coded blue) while the first layer AFTER the raft is still being printed too fast (still green). It is as if the software is speeding up the first layer on purpose which effectively ruins every print that requires a raft.
I know I can just reduce the default speed to something like 30 mm/s but that would slow down the entire print unnecessarily. Reducing the raft separation distance may help but this would make the raft harder to remove (I am using 0.2 mm). The first layer settings in the layer tab doesn't help as I am using a raft. I have no intention of using a brim.
Is there any way that we can explicitly control the speed of the first layer AFTER the raft (without using separate processes which is sort of fuzzy and hard to use)? If not, this would be a very very helpful feature!
Thank you for your help!
