DittoPro Profile in Cura

Julio

Hi everyone.

Our DittoPros are being used in an educational institution. Although Tinkerine Suite is a great software application, we would like to expand the software support we provide to our students. We were thinking of introducing Cura alongside with Tinkerine Suite to our students. Our rational is that we would like our students to be prepared to use a wider variety of printers/software once they leave our institution (and our printers).

Can someone please share with me the following printer settings in order to prolong our DittoPro printer's lifespan and to continue to utilize our DittoPro printers with Cura (as well as Tinkerine Suite)?

Printer Settings

X (Width) = mm

Y (Depth = mm

Z (height) = mm

Is the Machine Centre zero?
which Gcode Flavor works best?

Print head Settings

X min

Y min

X Max

Y Max

what is the Gantry height
what is the nozzle size

Start Gcode settings. By default Cura selects

G28 ;Home

G1 Z15.0 F6000 ;Move the platform down 15mm

;Prime the extruder

G92 E0

G1 F200 E3

G92 E0

Eng Gcode By default Cura selects

M104 S0

M140 S0

;RETRACT THE FILAMENT

G92 E1

G1 E-1 F300

G28 X0 Y0

M84

Hi Julio, here are some settings that you can use in Cura, but note that we haven't tested these ourselves; these are the settings from Tinkerine Suite so you may have to tweek them to get your prints just right.

Printer Settings

X: 215mm

Y: 160mm

Z: 220mm

Machine Center is NOT zero

Reprap Gcode flavor works best

Print head Settings

Not sure what these are referring to.

Nozzle Size: 0.4mm

Start Gcode:

M104 S220

T0

G28

G90

M106 S0

G92 E0

End Gcode:

G91

G1 Z0.2 E-4 F2000

G4 P600

G28 X0 Y0

G91

G1 Z80 F3000

M106 S0

M84

G90

Hi Justin. Thanks for the support. I'll test these settings and update this post.

For posterity, the above ending gcode is missing a crucial line. Here's the ending gcode I've seen tinkerine studio generate:

;End GCode
M104 S0 ;extruder heater off
M140 S0 ;heated bed heater off (if you have it)
G91 ;relative positioning
;G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
;G1 Z+0.5 E-5 X-20 Y-20 F12000 ;move Z up a bit and retract filament even more
G1 Z0.2 E-4 F2000 ;move Z up a bit and retract filament even more
G4 P600 ; dwell time of 900 ms
G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way
G91; use relative
G1 Z80 F3000; drop 80mm
M106 S0; turn off fan
M84 ;steppers off
G90 ;absolute positioning
;

Note the G91 line. Without that the gcode will tell the printer to move the bed to 0.5mm instead of moving it to 0.5mm away from its current position. The difference means shoving your freshly printed part into the print head shortly before attempting to move the print head to its home position. And this can be difficult when it has to drag a hunk of plastic stuck to a glass bed which is in turn clipped to a stationary platform. It's not a beautiful sound.

Anyway, I can confirm that the end gcode in this post works.

Good catch! Indeed the gcode I posted earlier was missing the G91 line. Thanks for sharing your findings!
