How to change the material cartridge


#1

The gcode to purge the material in the tube to the printing tip is:

G0 Y100 F100

You can modify the Y value to adjust speed and F to adjust the duration of extrusion. Be careful not to go too fast for a very viscous material, as it will cause stress to be built up in the system.

REPEAT: DON’T PURGE TOO FAST, IT MAY LEAD TO STRESS BUILD UP AND FAILURE OF THE DISCOV3RY.

Hey, so we just took our Discov3ry out of the box and got all the hardware hooked up. We are doing a nutella test print to begin. I made the (seemingly) appropriate changes to the G-Code:

M302 ;Allow cold extrusion
M92 E10000 ;Increases extruder steps (required to turn Discov3ry)
M500 ;Store new temporary M92 settings
M501 ;Set temporary parameters to current M92 settings

But how do we ensure that the material in the syringe/cartridge is extruded to the nozzle initially? We pushed it through manually but that doesn’t seem right. Any tips?


#3

is there a script for purging the tubing out? right now we’re just running ‘empty’ prints.

@colerainey and @raw

The gcode to purge the tube to the tip we use is

G0 Y100 F100

You can modify the Y value to adjust speed and F to adjust the duration of extrusion.
