i don’t have WS2812B led strip , i only have some WS2813 LED STRIP if your controller can work for it or not ?
Pinot and voltage looks about the same, it should work. If not, the alternatives are inexpensive.
Since I’m waiting on parts to finish the Z axis installation guide, I figure I’ll move on to the next one, Lighting. Since I’m making this second unit a functional prototype testbed, I’m adding on all the upgrades my primary Taz has. So, here’s the new parts. New lightbar ends, and new corner cable covers. The cable covers are designed to work with aluminum extrusion slot covers (specifically these ones: http://www.mcmaster.com/#47065t93/=13j4f4b
The theory is that the slot cover acts as a cable hiding duct. Poke a hole where you want the lightbar ends, then stick it in place. the new lightbar ends cover the hole in the slot cover and hide the wire all the way into the bar. The corner cover hides the connection points and allows the wire to transition into the side wire duct in the top of my new Openrail Z top bearing holder plates. Once the lower cable covers are done, this will in theory allow you to route wire to any corner of the taz in a hidden path. The lightbars themselves are also getting an upgrade to add some directional vanes to the edges. More to come!

Pictures of the new covers and the new lightbar endscaps along wiht the slot covers in place. With these I can get 4-6 wires from any corner of the Taz all the way down to the top of the Z motor block without any wire exposed depending on size of the wire. There will be at least two more pices to this setup, a slightly larger unit that goes on the back of the LCD mount and allows for a cleaner lcd wire transition without zip ties, and a piece that goes from the Taz 3 control box back to the cable junction. The intent being to cover the cables before they go into the cable chains just to make things look nicer. The top rear covers do reduce maximum Z height slightly, but no more than the reinforcement brackets already in place there already do, and I get 3/4 of that back with the openbuilds Y axis anyways, so i’m not really too worried about it. I may clearance those brackets a bit later as it wouldn’t take much to get full travel but that comes at a structural reinforcement cost. and the cover bracket despite how substantial it looks, essentially adds nothing in the way of stability due to it being hollow.
Next up, the lightbars themselves get a rebuild. i’m going to make them able to fit the “poke through” connectors, because I hate trying to solder the damned things.
Once I recieve my new roll of 24v LED’s, there will be much more wiring detail here.
Edit: also installed the new “I don’t have a box on that side and that side of the frame seems to wiggle slightly more reinforcement aluminum plate of doom” it’s just an aluminum plate with 4 holes in it painted black. I may patent it, so no one steal that idea ok?
Since this is becoming the catch all for my “hide the wires” project, these might be of use to the Taz 3 control box owners out there. And maybe the 4/5 owners as well. The upper bracket allows you to get rid of the upper lcd ribbon cable zip tie, hides the connectors, and gives you a path into the slot cover if you are doing the lighting mods. The bottom piece allows you to eliminate the lower zip tie, and will only fit a Taz 3 setup.

Believe it or not, this is really contributing to the sensor project, because i’m building the wire path over to where the sensor mount will be. You can see the Fillament monitor rework in progress here: The small levers at the back are rocker arms that will press the buttons on the back of the monitor when the larger buttons on the front of the whole cover unit are pressed. I have to route one of the buttons around the fillament hole, and then make them printable, etc. Needless to say the assembly will be several pieces
other parts, i’ve finished the LCD cable cover, and I’m damned proud of the new LCD cable line. No zip ties, no tape, perfectly flat.
Since I don’t have a lid for my Taz 3 spare control box that I am installing on the new build clone Taz thing i’m building now, I decided to modify DiscoJohn’s Raspberry Pi case cover thing for a Taz 3. it works pretty well so far. Now I have to get a Raspberry pi and all the accessories for that. I’m thinking of making a secondary LCD mount on the front of the control box for a Rapberry pi local control touchscreen to supplement the 3d printer touchscreen. That would require buying an LCD though, and i’m not sure I want to spend money on that yet, so we’ll see.
Anyways, here are a bunch of pictures,

Looking good!
I’m working on the wiring for my rebuild now, so it looks like I have a little more printing to do. 
Thanks! Let me know if you have any cover additions you want. I’m already planning some pieces for the lower wire runs as well.
Will do.
Looking up your cable chain thread too while I’m printing some parts…
I have new anchor parts for that I haven’t uploaded yet too. The mid anchor still needs redone but the z to x and x end anchors will be uploaded tonight.
Ok, cool.
I checking through the thread to see what the parts looked like and what had to be done, but I still have to order the chains.
Here’s the anchors so far, also the redone igus block mount. The middle X axis to Z one will be done tomorrow most likely. There is also a cover for the X frame one that I may get done tonight.

Awesome! Thank you.
Here’s the last cover for the cable chain segment, this one goes on the Z to X frame mount and covers the gap between the cable transition duct thing and the cable chain itself.
After this one, I’m waiting on more slot cover stuff from mcmaster carr before I can see if I can hide the lower wire runs.I know my lightbox wire for the color LED’s is going to be tricky, the far Z motor and the Y motor and endstops will also require some care to hide their wires. I’m thinking a front run that spans the entire frame width, probably printed in 3-4 sections, with a C channel that will let me run the LeD and switch wires to that box and the Far Z axis motor and Y max endstop wires. The rear Y axis motor and endstop I think I can potentially run in the channel covers with a transition piece of some sort, and the near Z motor will dump directly into the control box. Assuming all that ends up working and not looking dumb or too fragile, that will give me a cable path to any corner of the Taz frame for future enhancements.

Here are some more of the cable path cover pieces for the lower end. There will be another set of back duct covers eventually, those give me a path from the Z axis in to the Y axis. I’ll need to make a main frame to Y axis duct of some sort still, as well as the Y axis ducts themselves which will be very similar to Coverback1.stl. This project ahs been somewhat more all over the place than normal, I expect to collect and publish all the cable path segments somewhere with more pictures and whatnot later. I want to get the X axis mounted before I post too many more pictures so everyone gets the full effect. Even compared to my existing Taz I’d say this new one is looking pretty cool.
