Assembling the Ponoko RepRap X Axis
UNDER CONSTRUCTION
Please, read the instructions through before you start.
The X axis assembly consists of a motor bracket, a carriage and an idler housing all transfixed by 4 off 500mm x 8mm diameter bright steel rods. The X motor bracket can accept NEMA 17 or NEMA 23 stepper motors. Use washers under the heads of all screws unless told otherwise. Where nuts can freely rotate, there should also be a washer between the nut and the plastic.
DO NOT remove protective paper from the 3mm slides used in the exchangeable extruder socket. You're reading the instructions through, right? You'll find it mentioned here.
- 17 off M3x16 screws
- 1 off M3x20 screw
- 19 off M3 nuts
- 22 off M3 washers
Do not do up the screws to full tightness until all the parts of the carriage are in place. You may need the wriggle-room.
Do not over-tighten the screws. This breaks the acrylic and means you either have to glue the bits together or hack a new part out of acrylic manually. Either will slow down your progress somewhat.
Put the washers on 3 M3x16mm screws and put them into the 3 holes on the side piece. Fit it to the base, then add the two M3x16 screws and nuts (don't forget the washers) to the right side of the carriage. Then repeat with the left side, but only fit the lower two of the screws to the back of the carriage on the right hand side (shown unassembled in the photo):
If you have some split washers handy, you might want to fit them on the screws that retain the chain clamps first. We don't know yet.
... and after all is done, your X carriage should look a lot like this one. Put it aside and save it for the next step, which is adding the socket for the exchangeable extruder. If you have the "redux" kit, the extruder is fixed and there is no socket, so you can skip that part.
