This is a small clip that fits in the hole above the motherboard and clips the cable that goes to the extruder – thus keeping it from touching the drive belt.
The model can be downloaded from Thingiverse to be printed.
The raft came lose at the end of the print so it was not completely finished, however it is still useful.
By testing the stepper motors and the heater from the ReplicatorG control panel I found I had connected the X and Y motors to the wrong controllers.
The correct way to connect them is:
Cheat sheet to test them:
The first challenge was that no green LED’s lit up on either the motherboard, the stepper cards nor the extruder.
All I could see was a red flashing light.
In short, don’t get confused by the error message. The power to turn on is not at the extruder, but at the motherboard.
There is a power switch on the lower left part of the motherboard – this should be turned on.
If you are getting this error when the power is turned on there, then something else is the issue 🙁
When all works well you will get a message about the motherboard version and extruder version in the text box below the main window (where the build area and model is shown)
