Customizable Nozzle Wiper

thingiverse

Make the most of your dual extrusion machine with this quick add on. Printing with two colors can often lead to issues with ooze bleeding color between your parts. This wiper will allow you to use Simplify3D or another custom G-gcode to cool your inactive nozzle and wipe it clean between tool changes. Print the part out and insert a rubber strip into the groove. Clamp the wiper to the left-front corner of your printer so that it wont interfere with the bed but will make good contact with both nozzles. Download simplify3D and load the FFF profiles. Slice your part and print! https://www.simplify3d.com/ Both the Makerbot 2X and the Flashforge Dual use the same size wiper at 110mm x 110mm iframe src="//giphy.com/embed/3o7ZewFeyGHVtbtWda" width="480" height="270" frameborder="0" class="giphy-embed" allowfullscreen="allowfullscreen"via GIPHY Custom Section Here is the tool change g-code we use ;****Tool Change Script Start M135 T0 G1 X-130 Y-70 F9000 ; Move to wait position off table {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 T1 inactive extruder to 165 C {IF NEWTOOL=0}M104 S220 T0; Set T0new active extruder to 220 and wait for it to reach temperature before proceeding. {IF NEWTOOL=1}M104 S220 T1; set T1 Heat T1 to 220 {IF NEWTOOL=1}M104 S170 T0; Cool T0 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
