Electronics Options

We have two possible routes to choose from.  If we need to fabricate the PCB ourselves, then we must use the Gen7 Electronics.  If we can have a board made at a board shop, we can use the Ultimaker v.1.5.4 PCB.

Option 1: Ultimaker PCB

There are plans available for the Ultimaker PCB - we could have this made and sent to us. We could source the parts and then stuff, program and assemble the shield ourselves.  Note: We are going with this option.

Option 2: Gen 7 Electronics

If we need to fab everything ourselves - we can use the Gen 7 Electronics option.

Mechanical BOM


Notes from Anna + Bruce email chain on the stepper extruder:  The small one in the lab has room for 2 extruders also and it takes the same steppers as the x,y,z:   all Nema 17
