Matt's 2nd MP3DP Repeat V4 Build

Mostly Printed 3D Printer - MP3DP Your Builds
1

I really enjoyed building my first MP3DP and then rebuilding it when Ryan released the V4. It has also been such a good printer to use. So I decided I should build another one! This time I made it 6" taller to give it room under the build area where I could put the electronics and hopefully some clean looking wiring.

I also plan to add a 7" TFT screen that will run an Octoprint plugin for Octoprint control and display. I am not sure which plugin is best for that yet.

The only thing I have left to order is a heated bed. I am not sure if it is just me, but I am struggling to find a good source for a heated bed. Does anyone have recommendations for a 220mm x 220mm 12V heated build plate?

Aliexpress shows:

base plate
build heater

“good source” ?

I don’t think you need the base plate. That looks like the support plate for an I3 style build. The MP3DPv4 plate is different, and best cut on your CNC.

I used one on my build. From bottom up, my MP3DPv4 has the following:

  • MP3DPv4 mount plate
  • Insulation
  • Heater
  • Aluminum Build plate
  • magnetic build plate

To me, the heater and the magnetic build plate were too flexible. You could possibly use just the MP3DPv4 mount plate as your build plate if you made it large enough to support all 4 corners of the heater and whatever top plate you went with.

In those two links you provided, if i chose the “build heater” option then I wouldn’t need the base plate. The build heater seems to already have the aluminum plate, right?

Also, it doesn’t have a thermistor included…

This is what I bought before for my first Repeat printer and it works great, but sadly it is no longer available and can’t find another amazon equivalent.

EDIT:

Actually… maybe this one? I have a feeling it won’t be the flattest but it is something.

Already considered 24V or mains? Here’s my stack layout… https://www.azab2c.com/make?v=0_1&r=1.4&s=bed&f=t

DM me your address and I’ll send you a thermistor you can solder on the plate if you choose to get one without. There are may different ways to connect the motors to the base and then the heated bed. I used 20/20 extrusion in a “T” shape with a wood sheet and then the heated bed and then a magnetic releasable top. The wood has channels for the electronics and it serves as an insulator since we are not getting to temperatures where it will combust.
