very slow printing fast traveling
-
Hi all, could anyone help me with my issue. I am trying printing with PLA and the speed when printing is very very slow, but travel move is fast as I expect. I do not know what I have wrong.
Speed is also slowing in time. At start it looks ok but it slowing down in time down to 20%. It is not caused by small object, I am printing large one. Fo example after 2 minutes of printing speed lower down from requested 105mm/s to 70 when it prints layer of big square. It looks like it takes to long when accelerating and then decelerating and I see pause(not big pause but noticeable) at end of the line. My second printer with duet3 has not this problem. Please help.this is output from M122 command and below is my config

This sounds like a slicer setting. What is the actual print speed requested in the sliced gcode file?

@milan-baca What slicer is that? I expect it's overwriting your configuration settings with M201 and M203 commands in the generated Gcode, but using mm/second rather than mm/minute that RRF uses. If you post the first 100 or so lines of the Gcode file, that should show what it's doing. There are usually options in the slicer to either not emit these to the Gcode, or a setting for RRF.
