Capacitive Auto-Leveling on TAZ 5

Sebastian has posted the 1.1 release with all of the Lulzbot specific code merged in the Software Development Thread if anyone is interested.

I’m also considering putting together a plug and play upgrade kit to add the inductive sensor, pre soldered opto isolator with the correct plugs, and instructions on installation. Is anyone interested in something like that?

I think the kit would be a good idea. Especially if you can buy the sensors in bulk.

Ill look into maybe doing a run of 5 kits.

After looking at parts, I think I can put together a complete plug and play kit, no soldering involved. The kit would include: all the proper connectors for install within the electronics case with no modification of the existing wiring or case, Prewired optoisolator, sensor mount, longer screw to mount it, the OMRON E2K-X4ME1 sensor, and updated Firmware (1.1 RC2 with Taz specifics merged by Sebastian). I’ll double check and get a BOM together tonight. It would make for a very painless install. The goal here is for parents to be able to do the install lol.

What are the communities thought son repurposing the old z-man switch to a zmax switch?

I’d be interested in a kit.

I don’t own a TAZ 5 (I’m actually on the fence btw mini and TAZ 5), so I can’t commit. But I’m a “maybe” on a kit.

I’ve begun to consolidate my upgrade process here for those interested. Once you have all the parts its a very easy upgrade.

Does that OMROM sensor have an indicator light to show when the glass is sensed?

EDIT: Nevermind, looks like it does have a red LED indicator light.

It does. And the printer is printing better that ever with the current setup. I’ll be upgrading to the open rails setup and Piercets anti wobble Z soon.

Thanks for the confirmation. Mine just arrived… and its on my “todo” list for the printer.

I’ll have to comb through the thread (its pretty long) to figure out what’s current to add the capacitance sensor…

Just ask if you have questions. I feel like I could do another in about 15 minutes now that I have experience with it.

Thanks! I definitely will.

The scary part is the firmware… I’ll have to go through the compilation in greater detail. The wiring and mechanical seems to be fairly straight forward.

I’ll have to read through the thread and summarize what I find for review before I start this endeavor. Coming from a printer which had an inductance auto-probe, it was sorely missed when I switched to the TAZ5.

I am planning on doing this to my Taz 5 as well. I have read though this thread a few times now and waiting on parts to be delivered. Does anyone have a picture step by step guide made up for this? Sometimes just reading how to do something people interpret words differently but with pictures included you convey the exact idea.

You can check my post on thingiverse.

I had your files already printing. :slight_smile:

I know how to do the servo with ramps 1.4. But still looking for the pictures of what wires to cut and solder to, the points on the rambo to connect to, etc…

I’ll try to get you some better pictures as I’m doing the openrails conversion on mine.

Just made the probe holder on the mill at work, took about 15 minutes between programming, cutting and sanding

Looks great! You may need to do a bit of finessing on the under side of the extruder mount. There is a small lip i believe that i had to sand off. You’ll know it if you see it on the underside.

The only wiring inside the case is:

  1. Clip the z axis endstop wires (I believe they are blue/black, top center of photo)
  2. Wire into opto isolator be sure you have the polarity correct. (red and black circle in photo, bottom left)
  3. Wire 24v into the opto isolator. On mysetup I used a JST connector to allow the power to disconnect easily.

So I want to do this mod but don’t know what firmware modifications I need to do. Can someone help?
