dremel milling toolhead for RepMan

youmagine

This is a toolhead designed for milling with a RepMan 3D printer. Feel free to adapt it to other printers such as Mendel, Darwin, or Makerbot. It should work well for milling 3D-objects using Skeinforge and PCBs using Visolate, or for precise drilling using a drill holder attachment and cutting using a 90° attachment and cutting-disc. To use this toolhead, you will need a Dremel Flex Shaft Attachment (Model 225) and a Dremel. Additionally, you will require an M5x95mm or longer screw or threaded rod. For documentation on milling with this toolhead, visit bitsfrombytes.com/wiki/index.php?title=Milling#milling_PCBs. For discussion and feedback, refer to the forum thread at bitsfrombytes.com/forum/post/milling-toolhead-o-thingiverse. Update: A video of my first tests using this toolhead for PCB milling is available. The results were satisfactory despite using a milling-bit that was too large and failing to properly secure the print-surface springs. Update: Experimental Skeinforge settings for milling are documented at bitsfrombytes.com/wiki/index.php?title=Milling#milling_in_3D. A video demonstrating the challenge of adapting this toolhead to other printers is available, with details provided at bitsfrombytes.com/wiki/index.php?title=User:MarcusWolschon/Challenges. To adapt this RepMan Dremel milling-toolhead to fit the Mendel, you will need 10 small parts or 2 larger ones. Refer to objects.reprap.org/wiki/Mendel_X-axis for guidance. Note that due to the poor design of the Mendel x-carriage, you may need to redesign the x-carriage-lower_1off or even the x-carriage-upper_1off to accommodate alternative tools wider than 22mm. If possible, design additional parts so that the extruder and mill can be switched with just 4 easily accessible screws.
