Anet A8 Purge Bucket

Hi Makers ! Recently, I've ordered a kit to print in dual color (https://www.aliexpress.com/item/3D-printer-E3DV6-Cyclops-dualhead-upgrade-kit-2WAY-in-1WAY-out-TL-Feeder-Prusa-bowden-splitter/32770576556.html?spm=2114.search0204.3.164.78d110d6hlK9pW&ws_ab_test=searchweb0_0,searchweb201602_8_10065_10068_319_317_10696_10084_453_10083_454_10618_10304_10307_10820_10821_537_10302_536_10843_10059_10884_10887_321_322_10103,searchweb201603_60,ppcSwitch_0&algo_expid=a762445b-3a1b-4537-9f08-208a400e22ae-21&algo_pvid=a762445b-3a1b-4537-9f08-208a400e22ae&transAbTest=ae803_3) Unfortunnaly, this kit need a purge tower everytime you will make a dual color print. So, to fix that problem, I've designed a purge bucket, which is very useful to speed up printing and don't waste too much filament ! So basically to do this upgrade, you will need this part + this one : https://www.thingiverse.com/thing:2445884 Of course, it is recommended to apply tape on the purge bucket to prevoid any smelting of the part (and of course, to clean the nozzle). Just look the picture and you will understand. Now, to use the purge bucket, you will simply need Simplify3D,and apply that G-Code in the "Tool Changing Script" : ;; Start custom tool change script M211 S0; G91 ; Switch from absolute positioning to relative positioning G1 Z1 F1000 ; Lift nozzle by 1 mm in relative positioning mode G90 ; Return to absolute positioning G92 E0 ; Reset extrusion distance (needed for following steps) G1 E-7 F1800 ; Retract filament by 5+7=12mm at 30 mm/s (1800 mm/min) on old tool G1 X236 F6000 ; Go to X=-9.5 at 100 mm/sec G92 E0 ; Reset again extrusion distance on old tool {IF NEWTOOL=1}T1 ; Activate tool 1 {IF NEWTOOL=0}T0 ; Activate tool 0 G92 E0 ; Reset extrusion distance on new tool G1 E51 F180 ; Extrude x mm of filament at 3 mm/s on new tool G92 E0 ; Reset extrusion distance on new tool G1 E-10 F1800 ; Retract filament by 5 mm at 30 mm/s G1 X[current_position_x] Y[current_position_y] F6000 ; Move to next position on print at 100 mm/s G91 ; Switch from absolute positioning to relative positioning G1 Z-1 F1000 ; Move down nozzle by 1 mm in relative positioning mode G90 ; Return to absolute positioning M211 S1 ;; End custom tool change script And... that's it ! I recommend to print the part horizontally to prevent waste with support... Happy printing !
