Introduction

Got a makerbot from revspace. Where one of it's members had it sitting on a desk for about a year without any good quality prints I decided to rob them and fix it completely with an overhaul

The fixes

• J-Head 0.35 printhead

The new J-Head extruded behaves much more nicely, doesn't jam up and gives a very nice output

• Teacup firmware

New teacup firmware makes it possible to use pronterface and slic3r as software. Giving much nicer control, monitoring and easier settings than any of the other old software.

• Rewire

Since it is a makerbot cupcake CNC with a seperate extruderboard and a steppermotordriver connected to the extruderboard rewirering was needed since the extruder steppermotor is now connected directly to the mainboard. The extruderboard is now the only switching and controlling the temperature of the heated bed and the extruded

New cables and connectors for the hotend are needed

• Printbed

The original printbed of the makerbot is very unstable this has to change

TODO: New printbed with glassplate and isolation

• Z threaded rods

they are bend in very ugly shapes. These needed to be replaced

• Calibration

X Y and Z calibration are very easy. Extruded calibration should be done at the right temperature.

TODO: extruder recalibration (again)

• Retraction

Since it takes a *lot* of steps (gearbox) to retract retraction time is slow, retraction is set to only 0.2mm during print

TODO: lower this value - get rid of makergear.

• Endstops

There are no endstops

TODO: install 6 endstops, drill holes to install them and wire them. (easy).

• Grease

TODO: Apply more.

Conclusion

It was a nice desing at some time, however newer firmware and a lot of improvements can make it a very nice and fast printer.
