Lowering acceleration/Better looking corners>?

[jcspball13]

I need to make a bunch of parts fast; got mine working pretty good a 100mm/s with PLA

But I noticed at the corners, they look a little rough

I remember reading about tuning acceleration to help this, but for the life of me cannot find the thread!

I am using Simplify3d; how can I keep the speed high but improve corners?

Is acceleration the way to do this?

viewtopic.php?f=3&t=12, search for "acceleration". Try M201 X1000 Y1000.

Great thread!

So where do I add that gcode?

If you're using Simplify3d (excellent slicer), you "Edit Process Settings" then go to the "Scripts" tab and add those lines under "Starting Script".

My starting script looks like this and the "acceleration" values are at the bottom:

M108 S255 ; turn on M2 fans
G28 ; home all axes
G1 Y50 Z0.3 F9600 ; move forward to avoid binder clips
G1 X205 Z10 ; move off platform
G1 Z0.4 ; position nozzle
G92 E0 ; zero extruder
G1 E25 F225 ; purge nozzle
G92 E0 ; zero extruder
G1 X190 Z0.1 E1.0 F1200 ; slow wipe
G1 X180 Z0.25 ; lift
M201 X1500 Y1500; // max accel print (def 3k)
M202 X1500 Y1500; // max accel travel (def 3k)
M204 S1500; // default accel for normal moves (def 3k)

cheers,
