if you got this after firmware upgrade (not changing anything else) then it's the firmware settings... not much in the firmware really
- steps/per/mm for XYZE
- max speed for XYZE
- acceleration for XYZE
- jerk for XYZE
so do some experiments with those, drop them big time (for e.g. I find that for most machines accel of 300 and jerk of 4 are great start positions for calibration, then you start raising accel till you start to get lower quality, dial back to good quality and then start getting jerk up .. ) see where you end up.. you can easily experiment ... manually edit g-code, make something like temp tower .. make a tower and then every 20 layer add manually
Code: Select all
M201 X400 Y400
M205 X4 Y4
... then after 20 layers
M201 X500 Y500
M205 X4 Y4
... then after another 20
M201 X600 Y600
M205 X4 Y4
... another 20
M201 X700 Y700
M205 X4 Y4
....
so do a manual change of the accel/jerk settings troughout print and look for differences in quality
So I tried acceleration at 400, 200, and 100, jerk at 4...no real change in the print.
Now that I think about it...I only really noticed it after the upgrade. Before the upgrade I was printing my 3dLabPrint Spitfire and was having lines as well but I was thinking that was from something else...perhaps printing at too hot of a temp. At the time I was just so happy at being able to print more than one piece at a time I pretty much ignored the lines thinking I would figure it out later. After the upgrade I had some other issues making my prints worse than usual but it looks now like my prints are at least back to where they were before the upgrade. So now I'd like to figure out how to get rid of these lines, get a good print, and still be able to print 4 pieces at a time...(Could never do that with Cura...kept getting holes in my planes).
So...lets go back to scratch on this and ignore the upgrade. How can I get my Simplify3D prints to look as good as my Cura prints?
