Solved Print Problems with CURA 4.5 and 4.6

topoli · June 2020

Hi There,

The problem with cura:

if I used the cura 4.5 - the printer hotend (z-axis) did not level up from home position at the beginning. In my case that causes a problem, I had no clamps for the diamond glass and I took some foldback clamps. Now the Nozzle was always touching the clamps. So the printer did not reach the startpoint of the print.

Or the Hotend was only traveling on the Y-axis - so ....

Now I found a solution. I took the Printer Start and End settings from the JGcreate and copied them in the Settings in the cura 4.5 / 4.6

(Preferences -> Printers -> Machine Settings (that works only for the activated printer))

Here the G-Codes I changed:

Original cura 4.6. Machine Settings A5 & A5S (with the problems I had)

; -- START GCODE --

G21 ;set units to millimetres

G90 ;set to absolute positioning

M106 S0 ;set fan speed to zero (turned off)

G28 ;home all axis

M420 S1 ;turn on mesh bed levelling if enabled in firmware

G92 E0 ;zero the extruded length

G1 Z1 F1000 ;move up slightly

G1 X60.0 Z0 E9.0 F1000.0;intro line

G1 X100.0 E21.5 F1000.0 ;continue line

G92 E0 ;zero the extruded length again

; -- end of START GCODE --

; -- END GCODE --

M104 S0 ;turn off nozzle heater

M140 S0 ;turn off bed heater

G91 ;set to relative positioning

G1 E-10 F300 ;retract the filament slightly

G90 ;set to absolute positioning

G28 X0 ;move to the X-axis origin (Home)

G0 Y280 F600 ;bring the bed to the front for easy print removal

M84 ;turn off stepper motors

; -- end of END GCODE --

Here the code I copied from JGcreate:

; -- START GCODE --

G28 ;Home

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

;Prime the extruder

G92 E0

G1 F200 E10

G92 E0

; -- end of START GCODE --

; -- END GCODE --

M104 S0

M140 S0

;Retract the filament

G92 E1

G1 E-1 F300

G28 X0 Y0

M84

; -- end of END GCODE --

Now printing with all the better possibilities of preferences / settings for the print was possible.

If some experinced user has some better G-Code or better troubleshooting or if I have to add some codes - you're very welcome

If I gave some wrong information or if someone has better one - feel free

I'll be thankful
