Cura ignores retraction speed

by Ender3Guy

Hi all,

Trying to figure out what Cura is up to. It ignores my retraction speed and retracts at about 20mm/sec unless the speed is below that. Slic3r doesn't have this issue so I know it can't be my printer.

Can infill pattern change X/Y offset every few layers?

by travbuilds

I would like to fill some prints with epoxy, or some other filler, but it seems like infill patterns are all "closed cell" patterns, so a liquid could not flow from one cell to the other, in the X-Y direction. If, say, every 10 layers you could do like a 50% offset of the pattern in the X or Y, that would "connect" the cells, and filling with a resin, probably by forcing it in with pressure, could then fill the entire object. Is there any infill settings I don't know about that could accomplish this? Thanks!

Help with model - extra layer

by pgrunwald

Hi All,

I'm trying to print the above model but Cura 3.6 is showing an extra 1/2 bottom layer and printing a skirt. I tried fixing the model in Meshmixer but the bottom appears to be flat. Is this a bug or am I missing something?

TIA,
Paul

why is cura slicing thin wall cube so weird?

by yashrg

Background: Ran a thin wall test on my Ender 3 after upgrading the extruder to EZR struder by seemecnc. (Couldn't update the firmware due to lack of female to female jumper cables so updated esteps are being sent from slicer at start of gcode)

Issue with slicing: While Slic3r creates a very logical path where the nozzle is traveling along the perimeter extruding all the time, never breaking/traveling or doubling a line, Cura 3.6 creates path where the nozzle does a travel move from one corner to the diagonally opposite corner before traveling back. And every other layer, it also does a travel move along the side only to extrude a small blob and come back. I have attached the gcode files so you can take a look.
Interesting things to note: when I import the slic3r gcode into cura for viewing, cura seems to think the entire gcode is just one layer.

Resulting Prints: Slic3r's test prints much better than Cura's. Didn't think to get pictures because I was concerned with the gcode.

Nozzle ejection pre print.

by Forrest2

Upon upgrading to 3.51 My printer lays down a double row of filiment along the left side of the bed. Done, no doubt to clear the nozzle and assure the filiment’s ready to go. A very handy feature, but I want to disable it.
How can I do that?
I’m looking forward to any help from you can give.
Thank you.
