Posted · Permanently changing default profiles

Hey all, 


I am looking to permanently edit the default profiles on Cura 5.4 and 4.3(There are reasons behind having an older version in use) to have acceleration control set to false by default. 
I work at a Makerspace in NY and we're having a lot of issues with people forgetting to change the default parameters for acceleration control (Which is set way too high for our machines, they keep shaking themselves into y-shifting during travel moves) I'd like to have the default profiles start with acceleration control off by default so that someone has to know what they are doing to actually mess around with them. 

Is there any way to manually find/edit the cfg files for the default profiles? I looked around and haven't had any luck finding them or anyone that's had this question answered already.


Thanks,
~Farcee (They/She)

    I think the best thing to do would be to send an M201 to each printer and lower the Max Accel within the printers.  You could "print" a gcode snippet something like...

     

    G28 ; Auto-Home      > optional

    G0 Z10 F600 ; Move up      > optional

    M201 X500 Y500 ; This example sets the Max X and Max Y accel to 500mm/sec²

    M500 ; Save settings in the printer

    G4 S2 ; Give it 2 seconds to complete the save

    M84 ; Disarm the steppers      > optional

     

    The M201 might be firmware specific but there should be a command to alter the defaults in the printers.  You need to check and make sure you are using the correct command.

    Changing the M201 setting means that no matter the setting in Cura for Print and Travel accel (M204 with P and T or with an S parameter in the gcode) when the gcode line gets to the printer, the limit would be enforced.

    Another alternative would be to put the M201 line into the startup gode of each printer.  There would be no change to the defaults but once the line is read it would remain in effect throughout the print and until the printer is powered down.  Upon powering it back up it would come to life with the previous default setting.

     

    What you cannot do is fool-proof it.  If someone wants to add an M201 X1000000 Y1000000 to their startup they could do it.  Unless they delete the file after bashing the machine there would be a record of that.
