Replacing the connectors on the stepper driver boards
These connectors are low-cost, as is the cabling for them. But they are not very neat. To replace them do the following.
Use a pair of tweezers to pull the gold-plated connectors inside the RJ45 shell and push them up through the top. Then pull them out from the top and straighten them out.
Next desolder each connection separately, pulling it out with long-nosed pliers. The plastic shell will then be easy to remove.
