E3D V6 Modular Print System (Magnetic) FINAL

youmagine

The inspiration behind this project is courtesy of Foehnsturm. We're taking a slightly different approach, but our goal remains the same (and he deserves credit). The purpose of this system is to enable dual head printing with diverse materials without worrying about nozzle collisions or oozing. Oozing will be contained within the tool storage area. Print with support everywhere. Support on the main grip unit should be removed before installation (the support in question is part of the design for printing it). Check out the photos of the robot to see the quality of prints I'm getting from this setup. Printed at 0.1, 65mm/s, no infill, and a full fan. Note that I encountered some issues with the E3D clogging. I added a few drops of light machine oil to the head break/heatsink and haven't had any problems since. You might want to try this if you're experiencing similar issues. The second head is height adjustable, but it will need to be mirrored in Cura (X way) so that it suits the opposite side of the machine (or you can choose to mirror the small head, depending on which side you prefer). Similarly, the tool mount can simply be mirrored for the other side (the one corresponding to the head, e.g. height adjustable). Here is the G-code I use, with a simple lookup and replace in Text Edit. I look up 'T1' and replace with:;EXTRUDER 1 DROP, EXTRUDER 2 COLLECTT1G0 F12000 X100.000 Y180.000G0 F3000 Y192.5 ; This Y coordinate is where the head needs to be in line with the wedgeG0 F12000 X50 ; Start of wedge in x directionG0 F3000 X4.7 ; Where the head terminates, finishing the movement to shear the print module awayG0 F9000 Y100.000 ; magnets sheared, pulling head awayG0 F12000 X180 ; To other side of machineG0 F3000 X199.7 ; location for adj module in x direction to pick it upG0 F12000 Y180G0 F3000 Y184.3 ; location to engage the headG0 F3000 X150 ; then slide it outG0 F12000 X120 ; safe areaG0 F12000 Y100 ; back to print;ENDYou may need to adjust the coordinates to fine-tune them for your Ultimaker. Just use the Ulticontroller and axis adjust to see where the coordinates are for you, and replace accordingly above. Same goes for the piece of G-code to drop off module 1, and collect module 2. Look up 'T0' and replace with;;EXTRUDER 2 DROP, EXTRUDER 1 COLLECTT0G0 F12000 X100.000 Y180.000G0 F3000 Y184.3G0 F9000 X150G0 F3000 X199.7G0 F9000 Y100G0 F12000 X50 Y180G0 F3000 X4.7G0 F3000 Y192.5G0 F3000 X50G0 F9000 X80G0 F12000 Y100;ENDCheck out all the photos to see where parts fit. The final pieces to complete everything have now been uploaded. Note that the fan wire for the main grip unit is supported by 3mm filament. There's now a piece to glue on top of the module for the filament to be pushed into.I've added a photo of the very first dual print. It was printed at 0.15 with no infill, no wipe shield, and prime tower, and no ooze shield. It's a little rough, mainly due to printing too hot. Also excuse the missing hand; the support structure came loose from the bed. I'll try another print and upload the results using the wipe shield.Comments and ideas for improvements are welcome.
