Slow Printing Speed #281

Closed goldenninja13 closed 3 months ago

goldenninja13 commented 3 months ago

For some reason after this recent update that changed the appearance of the slicer I am getting really slow printer speed. I have tried changing my minimum movement speed but it seems like it is still overriding that value. If I had to guess it prints at about 1/10 of a mm/s. I'm using an ender 3 v2. It wasn't doing this until this update.

can you attach a workspace (.kmz) that I can use to replicate? keeping the same workspace and switching between 4.0 and 3.9 produces very different gcode?

goldenninja13 commented 3 months ago

It's not allowing me to attach a (.kmz) file type in github

please email to [ sa at grid dot space ] or DM me on Discord. thanks

this looks like a rendering bug in Preview mode (checked every version back to 3.6). in the example you provided, the rendered paths are showing up as very slow, while the actual gcode does not match. when I re-import the generated GCode, it's a totally different picture showing more normal extrusion rates. this particular print shows a 4.5 hour print time.

this is a good torture test. I'll use it to figure out what's going on and report back here.

goldenninja13 commented 3 months ago

Thank you. The thing I don't understand with it is it will run like normal for a little bit but then it will change and move so slow it doesn't even look like it's moving. So I would have to think that somewhere when outputting the gcodes it is not sending the right values. The print I sent you was printing like normal for the first 30 minutes and it did seem like it was only going to take 4-5 hours but then it slowed down and has now been printing for 80h and is only 55% complete.

aha. your output speeds are all 0, which leads to undefined behavior.

when I put in more sensible settings, things turn out better. I would also recommend using linear, triangle, or grid infill. Gyroid isn't helping here and takes tons more memory.

there is one remaining issue which is the model reports as 'non-manifold' which leads to a solid layer in the middle of the otherwise hollow sphere (it's in the trench area). i'll see if there is anything I can do to work around that, but fixing the model would be helpful.

goldenninja13 commented 3 months ago

I figured that was probably an issue but I did print this model before the update and it printed completely hollow.

I've added a fix for the non-manifold slicing that will be in 4.0.6

goldenninja13 commented 3 months ago

Thanks for the help
