  1. At last, I've found the solution : there are two versions of Cura json files for the A10M. One of them doesn't works for me. The good one is on Geeetech forum: http://www.geeetech.com/forum/viewtopic.php?p=89761&sid=c51926817bf3f514d4c61542c44767f7 There are some changes to make in Cura Machine Settings : size of the printer setting is wrong, change the width, depth and height (X 235 Y 235 Z 260. And in Left and Right extruders tab: Size nozzle 0.4 and material 1.75 mm. In Cura all the G-code is in the Printer tab. Extruders tabs are empty. And it works fine even for the prime tower. I think I'll need to configure its size for a better purge but it is already a big improvement. In Start G-code, I've added G-code for drawing two straight lines before beginning printing and in End G-code to bring the bed at the front for easy removal of the print. Here is my Start G-code G28 ;Home G29 ;For ABL G1 Z15.0 F6000 ;Move the platform down 15mm ;Prime the extruder G92 E0 G1 X7 Y25 Z.3 F5000 G1 X7 Y180 Z0.3 F1500 E0 G1 X11 Y180 Z0.3 F5000 G1 X11 Y25 Z0.3 F1500 E0 G92 E0 End G-code M104 S0;Cooling the heat end M140 S0;Cooling the heat bed G92 E1 G1 E-1 F300 G28 X0 Y0;Home X axis and Y axis G1 Y220 F6000 M84 Left Extruder and Right Extruder tabs are empty Hope it will help some users. If someone want the explanation in French, let me know.
  2. No result, still the same as before. I'm thinking to try reinstalling json files or look at Marlin firmware. For the moment I'll take a break and print only with one color at a time. I'll come back if I find a solution.
  3. Thank you I'll try that. A skirt is only for the first layer so the problem isn't solved for the purge betwen colors in higher layers... I'll tell you later if your solution works for the gcode for the A10M.
  4. I use Cura 3.6.0 Here is my configuration : Printer Start G-code ; Custom Start G-code G28 ; Home all axes G92 E0 ; Reset Extruder G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line G92 E0 ; Reset Extruder G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed ; End of custom start GCode End G-code ; Custom End G-code G4 ; Wait M220 S100 ; Reset Speed factor override percentage to default (100%) M221 S100 ; Reset Extrude factor override percentage to default (100%) G91 ; Set coordinates to relative G1 F1800 E-3 ; Retract filament 3 mm to prevent oozing G1 F3000 Z20 ; Move Z Axis up 20 mm to allow filament ooze freely G90 ; Set coordinates to absolute G1 X0 Y{machine_depth} F1000 ; Move Heat Bed to the front for easy print removal M84 ; Disable stepper motors ; End of custom end GCode ----------------------------------------------------------------------------------- Etruder 1 Extruder Start G-code G1 X{prime_tower_position_x} Y{prime_tower_position_y} F20000 T0 P0 G92 E0 G1 E3 F5000 G92 E0 M18 E1 Etruder 1 Extruder End G-code G1 X{prime_tower_position_x} Y{prime_tower_position_y} F20000 G92 E0 G1 E-3 F5000 G92 E0 ----------------------------------------------------------------------------------- Etruder 2 Extruder Start G-code G1 X{prime_tower_position_x} Y{prime_tower_position_y} F20000 T0 P0 G92 E0 G1 E3 F5000 G92 E0 M18 E1 Etruder 2 Extruder End G-code G1 X{prime_tower_position_x} Y{prime_tower_position_y} F20000 G92 E0 G1 E-3 F5000 G92 E0 With the 1rst extruder all is correct, the prints are perfect. But when I want to print with 2 colors, after printing the 1rst color the nozzle stay in place for several seconds, doesn't move to the prime tower and, before beginning the 2nd color of the model, the temperature fall (in the LCD screen to 175°) so the extrusion isn't hot enough for the 2nd color. I've tried to put some M104 instructions in some places but with no result... Thanks for your help !
  5. I have the same problem with my Geeetech A10M (one nozzle two extruders). It's very frustrating, I cannot print a bicolor model with Cura. My printer works in bicolor models in Repetier-Host using Cura profile where the gcode is situated in one place for both the printer and the extruders. The dual extruder is configurable (one nozzle for 2 extruders), while in Cura this configuration doesn't exist....
