Hiprecy LEO - Z Axis Linear Rail Conversion

thingiverse

I created these designs to convert the LEO Z axis to a linear rail system. <b>Parts required:</b> -Linear Rail & Block, 350mm, MGN12H (2 sets) -M3 x 8 Screws (28, if using optional rail caps) -M3 T-Nuts (12, if using optional rail caps) -Print of 'Linear Rail Bracket L' (1) -Print of 'Linear Rail Bracket R' (1) -Print of 'Linear Rail Spacer' (2) -Print of 'Linear Rail Shim' (1) -Print of 'Linear Rail Alignment Tool' (3) -Print of 'Linear Rail Top Cap' (2, optional) -Print of 'Linear Rail Bottom Cap' (2, optional) -X Belt Tensioner shim The photos included show where all the parts go. <b>Assembly notes:</b> -I used 4 screws in each rail evenly spaced -The X gantry will need to be removed to install the spacers -Align and tighten the 4 screws going into the sides of the brackets before tightening the 4 that hold the bracket to the block. This will require the X stepper to be removed. -When installing the rail, I use 3 alignment tools, one on each end and one in the middle. The tool has a hole in the middle to allow an Allen driver into the screw under the tool. -After everything is assembled and working, you will want to home the Z axis and loosen the lead screw nuts to allow them to re-center themselves, then tighten them back up. Make sure you do this with the lead screw bearings installed in the top plate if you had previously removed them. <b>About the rail caps:</b> These were designed to be purely aesthetic and perform no function, BUT... if you don't use anti-backlash nuts like I do, the top caps will become the stops for the Z Axis Calibration routine. This works fine (and is a lot quieter) if they are even so the calibration adjusts the gantry properly. Measure from the X gantry to the bed on both sides after calibration to make sure it is even. If not, adjust one of the caps up or down a little. If you don't want to deal with that then leave the top caps off. <b>Update 9-21-20:</b> Added the X Belt Tensioner shim to the list of required parts. I had it in the photos but not in the parts list. Thanks to maralb1970 for pointing that out.
