Customizable Nozzle Wiper

thingiverse

Get the most out of your dual extrusion machine with this easy add-on. Printing with two colors often causes issues with color bleeding between parts. This wiper will let you cool your idle nozzle and wipe it clean using Simplify3D or another custom G-code for tool changes. Print the part and insert a rubber strip into the groove. Attach the wiper to the printer's left-front corner so that it won't block the bed, but will make good contact with both nozzles. Download Simplify3D and load FFF profiles. Slice your part and print! Visit https://www.simplify3d.com/ for more information. The Makerbot 2X and Flashforge Dual use the same size wiper, measuring 110mm x 110mm. <a class="giphy-embed" src="//giphy.com/embed/3o7ZewFeyGHVtbtWda" width="480" height="270" frameborder="0" allowfullscreen="allowfullscreen"></a> Custom Section: Here is the tool change G-code we use: ;Tool Change Script Start M135 T0 G1 X-130 Y-70 F9000 {IF NEWTOOL=0} M135 T1; {IF NEWTOOL=0} G1 X-160 E30 F3000; {IF NEWTOOL=0} M135 T0 {IF NEWTOOL=0} G1 X-130 Y-70 F9000 {IF NEWTOOL=1} G1 E30 F3000; M135 T0; G1 X-130 Y10 F9000; G1 X-130 Y-70 F9000; G130 X20 Y20 Z20 A20 B20 Lower stepper Vrefs while heating {IF NEWTOOL=0}M104 S170 T1; Set inactive extruder to 165 C {IF NEWTOOL=0}M104 S220 T0; Active extruder set to 220, waiting for it to reach temperature. {IF NEWTOOL=1}M104 S220 T1; Heat active extruder to 220 {IF NEWTOOL=1}M104 S170 T0; Cool inactive extruder to 165 M133 T0 M133 T1 G130 X127 Y127 Z40 A127 B127 Default stepper Vrefs {IF NEWTOOL=1} M135 T1; {IF NEWTOOL=1} G1 X-160 E30 F3000; {IF NEWTOOL=1} M135 T0 {IF NEWTOOL=1} G1 X-130 Y-70 F9000 G4 P1000 WAIT {IF NEWTOOL=0} M135 T0; {IF NEWTOOL=0} G1 E30 F3000; G4 P1000 WAIT M135 T0; G1 X-130 Y10 F9000; G1 X-130 Y-70 F9000; G1 X-130 Y10 F9000; G1 X-130 Y-70 F9000; G4 P1000 WAIT ;Tool Change Script End
