Very nice! I see you have the proximity limit switches? How is that working for you?
It’s much more accurate when you have to reset your machine. I love them!

Proximity switches are game changers. XYZ datum is maintained even after complete system shut downs and multiple re-homes. Things you learn quickly NOT to do with the stock physical switches.

Teach me please lol! Are they hard to wire and setup? You made your own brackets?
I bought mine from @Luke old store. Came with brackets and wires, direct swap for the old ones. I wouldn’t be surprised if C3d offered them eventually.
Don’t have a link but they are available on line. Also, there’s a post here in the forums about shielded cable if you end up making your own.

Thank you I will be shopping for these asap.
If you need to have a more detailed look at how Luke’s prox switches were installed (I have those too) you can check this, most of it will still apply whatever model you choose to buy.

This is why this forum is great… Just took delivery of aliexpress limit switches, came here to catch up on new posts before searching for info on prox switches and poof here it is…

Load testing my new 9mm Z axis belt upgrade.
This was an 18lb load test with the billet upgrade and open ended 9mm steel core belt. With this upgrade, the Z axis can now output the same force as the X axis and use inexpensive open ended 9mm belts. Works seamlessly with carbide motion.

What happens when you power off the Z motor with that weight? 
Simple and Elegant btw

My thoughts…if Carbide3d tells everyone the HDZ isn’t for everyone… then we need to continue development on the stock parts for those other people. I’ve personally bought two HDZs and I fully support that piece of kit but it’s a good $$$ jump.
This 9mm upgrade removes one of the weak links and increases usability due to flexibility, you now can use whatever belt you’d like. It’s a simple billet bracket set that can be machined by the user with a 1/8th endmill and V bit.

That with an EasyTram would probably go a long way for an inexpensive upgrade. Luke made those plans available free too. I used the easytram before getting an HDZ and it was stiffer than the stock Z plus it provided the ability to tram the Z in the X axis like the HDZ.

The main reason for this upgrade was to increase the drive strength for a 4.5" travel medium duty Z axis that’s almost operational. Its good to make these parts cross compatible with stock though.
I wouldn’t be opposed to making the drawings free but was thinking of a small charge, maaaaybe $5 for cam included. Made by a shapeoko, for a shapeoko has this certain ring to it 
I’ll probably release these drawings once everything is finalized as well.

That is incredibly reasonable. Similar to how Ben Myers runs an Etsy shop where he sells designs for parts to make with a Shapeoko, you should charge for your products to compensate you for the time and effort you put into your designs and great information you share on the forums. I’d be glad to pay for this design and make it for my buddy who still uses the stock belts.

Billet radiator brackets for a 1000whp+ 2jz240. Practice in Fusion360 toolpath manipulation and bitsetter was used to post six toolpaths in one block.
Better look fast if you’re not sure you’ll go fast.

Griff! (and everyone) -
Going back to the proximity sensors - why are these better than the mechanical switches? Can you give us a lesson on that?
Unless I modify the G-code to remove some last commands, my S03 heads back and does the re-init /re-zero after every job. I’ve never really understood why. If you care to educate me on why, great, but the big question is: how do the prox sensors change things in that context (and whatever other context you can conjure.).
Thanks in advance -
Chris

Sorry, no I cannot. I’m very much a pragmatic neophyte machinist.
I can tell you that @Luke was my primary influencer. @gmack, hopefully will chime in, he’s a big contributor here when it comes to how and why things work or don’t really work the way we think.

Prox switches are more accurate, and less prone to failure as they don’t use any moving parts.
We are currently working towards a really high quality official C3D limit switch upgrade kit too.
