This is my 3D printer, once a Cupcake MakerBot, it's now a unique blend.

Cupcake155's life is chronicled here:

It was the 155th MakerBot, a Cupcake. I got the kit back in the day but gave up after multiple catastrophic extruder problems. In Jan 2015, the pain of not having a printer grew too strong and I decided the corpse of my Cupcake was still much of a printer. I gutted the electronics and extruder and adapted parts from other RepRap type machines.

Cupcake155 has the following features:
* 0.3mm nozzle (adapted MK8 Prusia Extruder)
* RAMBo motherboard (
* Wifi-endowed Raspberry Pi running Octoprint
* Dedicated Arduino for Illuminatrix Lighting system
  • 1 × MakerBot Cupcake Batch 6 Kit My machine's frame was a batch 6 MakerBot Cupcake
  • 1 × RepRapElectro RAMBo Motherboard I used a high-quality RAMBo board implementation to drive everything
  • 1 × MK8 Extruder I picked out a Geeetech MK8 extruder on ebay. 0.3mm Nozzle
  • 1 × Assorted Connectors Digikey provided a number of minor connectors to help make things clean
  • 1 × 3mm Aluminum Build Plate A local machinest provided some 100mm x 100mm x 3mm build plates, they're held on with tape.

You're most welcome Ben. Yeah, I spent a few hours on this. I empirically computed the steps/mm as I probably mentioned somewhere. I measured many many many times and worked-out the average which seems to work extremely well. The RAMBo was probably overkill, but I love it so much. 

I also highly highly recommend printing from SD and a cooling fan is very worth it.

I'd love to see some pics.

Thank you! This helped getting my old cupcake up and running again. I used RAMPS, but have the same extruder/hotend. I had to double the steps per unit, I think I must have 1/32 steppers. Saved me a ton of time!
