I need a place to keep my needs together and hopefully document my progress on install Piercets Openrails Conversion on all three axis as well as the anti wobble Z nut. So far I have ordered a bunch of hardware and am in the process of printing the parts. I’ll document my progress below.
Goal:
To upgrade my TAZ 5 from the misumi linear rods to the open rails style setup on all three axis’.
I believe this is a comprehensive list but I will update as i do the install over the next few weeks. I printed everything in black Gizmo Dorks ABS at 85% infill. I had 2 nozzle clogs. It took about 1.5 spools to do everything,
Parts Printed:
X Axis:
-Openrail Idler Tensioner x1
-X Carriage x1
-Idler Endcap x1
-X belt Bracket x1
-X motor endcap x1
-X motor mount lid x1
-X mainblock x1
Y Axis:
-Openrail corner x2
-Openrail Y support x6
-Drill Guideplate small x1
-Drill Guideplate large x 1
Z Axis:
-Left Motor mount standard x1
-Right Motor x1
-Left Top x1
-Right Top x1
-Backplate Anti wobble clearance x2
-Backbrace x4
Anti Wobble Z Nut:
-Double nut Bearing holder x2
-Z nut bottom x2
-Z nut upper x2
Worked on the x carriage today. I never could get piercet’s backplate file to open so I drew my own up and laser cut it out of 3mm acrylic. Should be plenty strong. I’m short one eccentric spacer to finish the carriage.
just found an issue with my backplate I need to fix.
Here is the corrected backplate
You will need to extract the m2 (?) Heat set inserts from the x endstop and set them in the new mount.
-Be sure the nuts from the bottom of the z carriage don’t hit the electronics box. Use the right length bolts and low profile nuts.
I hate slide in tnuts.
-I gave up on several of the t nuts on the front side of the motor mounts. I’d have had to cut down an allan wrench to get to them.
-Slightly loosen the 4 screws that hold the y Axis to the lead screw for smoother performance.
I think all of my parts are here now. I have a mess to clean up on my desk before I start building. Hopefully this week I’ll be able to get everything done as long as I have all the right parts.
The plan is to do the y axis completely and then build the others off of the machine in case I need to reprint anything. The x,z,and z anti wobble be done all at once.
Got the y axis done and preassembled most of the rest. I’m short a few parts so I had to place another order with openbuilds. The y axis worked out just fine, however I am a bit concerned with how tight the bearings are. It is much more difficult to move by hand, but it prints just fine. How tight is right with these builds?
I checked it a bit ago. I had the bearing preload way to tight. I loosened them up and its smooth as butter now. I never could get your backplate opened so I drew up a simple one and laser cutnit out of 3mm acrylic. I’ll post the dxf later. I’m waiting in more tnuts and m5x10 hardware to finish the x and z axis. Then i need to find the steel rods for the anti wobble kit.
The z axis is assembled and installed. The y axis is done completely. The x axis is mostly assembled but I’m waiting for hardware to finish it. My acrylic backplate seems to be just fine although time will tell if there is too much flex in it. If I had the tnuts I need I would be done completely. The z axis is a bear to install, mainly getting the tnuts to stay in place while you install the bolts. At this point I’m not sure if I’m going to do the anti wobble mount or not.
