set the g code flavour to reprap in the printer config in cura.

@Veti that's how it is already imaged, but it still prints slowly

Veti

post the beginning of a g code where it is slow.

hannes0913

@Veti what do you mean?

T3P3Tony

@hannes0913 the file you are trying to print, that is printing slow. Please upload that.

Your jerk is really low. I would multiply that by at least 60. Don't for get it's in mm/min

that is in mm/min

500mm/sec is 8.3 mm/sec. that is really slow

are you sure that you set the flavor to reprap in cura?

@Veti If you are running a recent version of Cura it comes with a pre-configured set of profiles for the Ender 3. I had the same problem. I assume that your speed settings shown above are in the Cura start.g. Go to start.g and comment out M201,M203,M204,M205,M220 and M221. The next print you slice will print at the speeds set up in RRF.

Veti

ah those are the CreawsomeMod settings. yes. they need to be removed for the duet.

chas2706

Yes that's correct otherwise the printer is extremely slow.
