compare gcode not settingsInspGadgt wrote:Comparing the settings I'm not finding anything that stands out different between Cura and Simplify3D but some of the settings I am having to guess what they are called in the other software.
I'm not using a spring tensioner and the belt is quite tight. Besides if that were the case it would affect all the slicers not just Simplify3Darhi wrote:btw the other issue that can make this ribbing you have prominent is backlash, so if you have one XY position when head is going CW and other when it is going CCW then it can be backlash, especially if you have springs on your XY axes (for e.g. those spring tighteners for belts that will cause this issue) .. you can theoretically "solve" the problem by making slicer always print outline in same direction (no clue how to make s3d do that, needed it few times myself) but that's just a hack, not a real solution, drop the springs, make stiff tighteners and drop the acceleration/jerk till you get good results
note also that lowering acceleration and jerk will (in a good way) affect precision of the small holes
So I tried acceleration at 400, 200, and 100, jerk at 4...no real change in the print.arhi wrote:no accel/jerk control in s3d
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
so do a manual change of the accel/jerk settings troughout print and look for differences in quality
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 ....
