How do I change the Y acceleration in GCode?

Hi there,

 

I'd like to play around with the  y acceleration within GCode, not the firmware.  I'm looking to slow it down, but not sure how.  Any advise would be greatly appreciated.

M201 X1000 Y1000 Z100 E2000  ;  set max acceleration

Gcode is the instruction set for the firmware.  As Obewan pointed out, M201 X Y Z E tells the printer firmware what the upper limit of acceleration is for each axis.

Cura adds lines using M204 S within the Gcode to tell the firmware what acceleration to use and it is not axis specific.

If you add a line to your Start-Up Gcode in Cura M201 X3000 Y500, and then within the Cura settings you enable Print Acceleration at 1000 then the X axis will be calculated by the firmware printer/planner at 1000mm/sec² and Y will be calculated at 500mm/sec² because the 1000 was above the Y axis limit set by M201.

 

If you add an M500 after the M201 line then the printer will take your new acceleration settings and commit them to memory as the new default.  You could then remove the lines from the start-up gcode.  Without the M500 the printer will forget the new setting every time you shut it off.
