After this step printer will be looking almost like finished.
Printed parts needed:
Follow the instructions, skipping step 4 (Placing Z-covers) and there is also additional steps needed with step 5, as we are using trapezoidal screws with aluminium couplers.
After placing the motors, install couplers and then insert trapezoidal screws into them, and tighten it all with the 4 screws on every coupler. Make sure that motor shaft and screw are not touching inside the couplers. Then go to Step 7, but as nuts use adapters and the chinese nuts.
After step 11 it should look like this:
I’m currently not managing the cables, as it will be also managed differently than in Original, so Step 13 can be skipped. All the following steps can be easily followed from the Prusa manual.
I’ve changed my mind about the frame, and instead of using 6mm MDF i am using 9mm plywood, which is more stable, and still in good price comparing to aluminum. Because of that some screws which I am using are longer than in standard one.
In next step we will make the printer moving, by installing RAMPS and connecting the motors which are already installed on frame.
