Summary

I have made some minor modifications based on the 4.6 version of the Smartrap, mainly the GT2 belt & pulley. This is a work in progress so I will be refining it as time allows. Unfortunately this upgrade requires both Z608 (x3) and Z625 (x2) bearings. I wanted to keep them all the same, but it is what it is for now.

Instructions

For the Y axis, all you need to do is print 2x of the lm8_holder_y_GT2.stl and 2 Z608_bearing_cap.stl. I secured the 2 ends of the belts with zip ties. No need to get fancy here.

For the X axis, you have a couple of options. If you have not started printing parts for your Smartrap, go ahead and print the plate_x_GT2.stl. If you already have this part, you can reprint the plate, or you can just print the Z608_bearing_holder_RevA.stl and fit it where the endstop would go. As you can see from the pictures, I decided to move the end stop to the end of the carriage and attach it to the X_end_with_endstop.stl. You'll also need to print the Z625_bearing_holder.stl and Z625_bearing_cap.stl to mount at the rear. I went with Z625 bearings because there just isn't enough clearance for the Z608 bearings due to the lm8_X_holder piece.

If you have any questions or if anything does not make sense, please let me know.

Enjoy.
