|Makerbot een revisie geven zodat die normaal werkt|
|Alle Projecten - Project Toevoegen|
Got a makerbot from revspace. Where one of its 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
- J-Head 0.35 printhead
- The new J-Head extruder behaves much more nicely, doesn't jam up and gives a very nice output
- New extruder
- 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.
- Since it is a makerbot cupcake CNC with a separate extruderboard and a steppermotordriver connected to the extruderboard rewiring was needed since the extruder steppermotor is now connected directly to the mainboard. The extruderboard is now only switching and controlling the temperature of the heated bed and the extruder.
- New cables and connectors for the hotend are needed
- The original printbed of the makerbot is very unstable, this has to change
- New printbed with isolation
- Z threaded rods
- they are bend in very ugly shapes. These needed to be replaced
- X Y and Z calibration are very easy. Extruded calibration should be done at the right temperature.
- extruder recalibration (again)
- Since it takes a *lot* of steps (gearbox) to retract retraction time is slow, retraction is set to only 0.2mm during print
- lower this value - get rid of makergear.
- There are no endstops
- TODO: install 6 endstops, drill holes to install them and wire them.
- Apply more.. always :)
It was a nice design at some time, however newer firmware and a lot of improvements can make it a very nice and fast printer.
