Detailed Change List

• Einsy Rambo Motherboard
  • Marlin 2.0 Firmware
  • No longer supports runout sensor
  • Wiring changes to endstops
• MK52 Heated Bed
  • Thermistor soldered to bed PCB
  • Connector for thermistor wires
  • Screw terminals for power connections
• 24V Integrated Power Supply
  • System is switched to 24V.
  • PSU is now bolted to the frame in the same position that Prusa uses.
  • Power switch is on the PSU as well as an AC power connector.
  • Spool holder had to be moved. Spool holder is now mounted to the side of the power supply.
• Pulse HV is switching to 1.75 mm
  • 1.75 mm filament has a higher surface area to volume ratio, so it can be melted faster. Switching to 1.75 also lets us consolidate parts by using the same threaded heat sinks as the v6.
• Frame changes
  • With the power supply bolted to the frame on the right side and a new frame brace on the left side, the frame is much more rigid. This will improve print quality.
  • New Y carriage to support the new bed
  • Changes to hole alignments to center the bed correctly
  • Moved holes to center Y idler mount
• Buildtak Flexplate has been dropped in favor of the MatterHackers Magbase
• New all in one wiring harness on hot end (previously used on some D series printers)
• Some component changes to support different voltages
  • 24V Heater cartridge
  • 24V Bed
  • 5V Heat sink fan
  • 5V Layer cooling fan
    • New fan is larger than old one
