The bottom one at A - the MIN connector - has been replaced by a 3-pin 2.54mm-pitch pin-strip connector. The two RJ45 connectors have been removed as above. The original is on the left the modified is on the right. The plastic shell will then be easy to remove. Next desolder each connection separately, pulling it out with long-nosed pliers. Then pull them out from the top and straighten them out. Use a pair of forceps to pull the gold-plated connectors inside the RJ45 shell and push them up through the top. The RJ45 connectors are low-cost, as is the cabling for them.

Replacing the connectors on the stepper driver boards If you have one, a solder sucker will also be useful.ġ00uF (107K) Radial-pin Aluminum Electrolytic Capacitor You will need a soldering iron, long-nosed pliers, forceps, and a small screwdriver. But the connectors they come with are for the MakerBot CupCake machine, not RepRap. If you buy ready-assembled printed circuits for RepRap that will save you a lot of time. Optional changes to convert from Makerbot RJ45 connectors to screw terminal connectors These 3 changes are relatively minor compared to the below option, but the choice is yours. Use MakerBot end-stops with RJ45 connectors Note that these are different from the molex connectors found on ATX power supplies.ģ.

Install Molex conectors on your stepper motors (all except the extruder motor). To eliminate the need for modifying the boards you will need to do three things.ġ. This option will save you a lot of time and reduce the risk of damaging your boards. You can leave everything on your boards stock except for adding the I2C pins needed for communicating with the extruder board. Thus this page is optional in your gen 3 electronics assembly.īefore making these modifications to your brand new boards consider the following option. Although less optimal, RepRap Mendels have been built with standard Makerbot gen3 electronics without problem.
