Project – 3D Printer

This is my take on a Prusa I3, with a cnc mill friendly frame. MP3DP- Milled/Printed 3D Printer. I am sorry the parts are not interchangeable with the original Prusa parts.

This uses common 3D printer parts, hardware, milled parts, and printed pieces.

Milled Parts

Material should be under 7.2mm thick, thicker and you will need longer hardware and might lose some Y travel. All radii and holes are 1/8″ or larger, so use end mills 1/8″ or smaller.

XY_Frame2(M)Front and Back
Y_Frame2(M)Sides
XZ_Frame1Main Piece

(M) Mirror one of these parts if you have a single sided material.

These .DXF’s are in millimeters.

 

Printed Parts

I used 20% infill and 3 perimeters for all parts, very forgiving. No support needed!

You will also need some extra wire for the power supply, end stops, and fans.

 

Firmware

RC8 BF 1/25/17

1/25/17 updated to the RC8 BF, much better response from the LCD and included Jeffeb3’s lcd knob settings. If you have any issues please just switch back the the previous firmware and let me know. I have had no issues with it.

OLD- MP3DP_RC8

16t pulleys, 32nd stepping, 8mm lead screws, full graphic LCD. Check your z axis after flashing some lead screws actually need 788 instead of 800 steps per mm in the firmware.

12/11/16 updated to marlin RC8

7/9/16 – Updated to Marlin RC1.06, tweaked the accelerations.

4/27/16 – initial release nothing beyond basic tuning, works great
