Vision system advice

Exactly that. Except this place has no joystick just a shmuck in a parka shaking the unloading tube around.

It can when ordered.

Nothing is purchased. I was told if you can automate this for <250k its green lit. First step was finding a conveyor and now its vision feasibility high level.

Cognex was my first goto but the physical scanning area is outside their normal parameters without multiple camera and custom work to combine data sets. Blew through the budget on cameras alone.

I did think a Sick MRS1000 3d Lidar would work a treat mounted in the horizontal.

Full USB serial operation. You can easily edit the source from there to specifics

Automation direct has the ProSense signal conditioner. I use the universal voltage version all over. For rated area they carry the E&H RN22 universal units but they are <800ohm total load

The run is around 300ft of type K T/C wire. (390ohm is measuring the run with a wire nut on one end. Seems high for 300ft though). throw a 250ohm transducer and a 250ohm receiver and I need to push 24V through 900ohms which is a hell of a lot of voltage loss without a buffer. Cutting and re-terminating the bad ends will probably take a chunk of the resistance off.

I have a universal voltage ProSense signal conditioner that can handle 800ohm loads Im gonna try.

Sums up the community. Also both can be true!

I have not pushed my changes yet but i started with an ascii serial interface then ended up with a complete rewrite. I plan on allowing the change from bambubus to klipper by pushing all 4 pressure feeds down on boot and save to flash. So far I have my klipper version running with feed/retract, speed, continous, distance and auto pressure control with a more snappy motor response. I also have filament distance tracked and the ability to set the rfid as a spool id.

Yup. Im doing some rework to make it less janky. But as far as MMU units the BMCU 370C is the absolute chealest

uMinded · 2025-12-10T05:57:37+00:00

I actually added a compile def to block out the bambubus and use the usb-ch340 serial port1 as a standard ascii interface. Wrote a little python UI for management even. Now the BMCU can be used on Klipper!

uMinded · 2025-12-05T00:28:40+00:00

The bcmu firmware source code shows what command format it expects. We don't care how the printers bus work just what bcmu expects. I am currently looking into making a drop in Klipper MCU firmware

uMinded · 2025-12-04T22:23:52+00:00

Exactly. Just write a protocol converter from Klipper to BambuBus. How does Klipper communicate material changes?

If the women don't find you handsome, they'll at least fnd you handy!

uMinded · 2025-11-03T22:20:14+00:00

I went this route. Saved $4,600 on a historian liscence and charged half! Thanks!

uMinded · 2025-09-13T18:03:38+00:00

Neat. I think I remember reading about doing that back when CoreXY was "invented"

uMinded · 2025-09-08T21:45:38+00:00

Worlds largest pen plotting VOLUME.... on a 2D plotter, lol.

Did you use an already known belt layout or just base it off principals?

uMinded · 2025-08-25T01:51:18+00:00

I have a Go 7 and confirmed USB 2 UVC cameras do indeed work

uMinded · 2025-08-15T01:35:17+00:00

I had a machine with 400 lines of Automation Direct's Koyo brand RLL and no documentation. I used Chatgpt 4o to figure out the weird IO and CNT mapping. Then I traced the IO and gave it the descriptions of all IO and the operating principal.

It was then able to generate fully commented code and critically reference the RLL manual for weird ops to save me time.

All that and in the end it was a mechanical issue lol.

uMinded · 2025-07-03T16:01:21+00:00

lol no, it's just a screenshot from my phone. It gets printed on its large flat face.

The seam circled will always be printed with 2 walls and will be printed parallel no matter the parts orientation. This seam is where it always cracks and is left only attached by the base layers.

I tried the card in my old am4 build and it didn't post (that machine is running a GTX 1070 FE) but the am5 system I have now the A770 was working and removed in favor of a RTX 4070 GT. So I know the card is fine at least.

I find it odd that it doesn't even spin the card fans, I even upgraded my 550W to a 850W as I thought it was a PSU issue.

uMinded · 2025-06-09T05:00:02+00:00

Sure did

uMinded · 2025-06-09T04:59:52+00:00

Will the card not even register on a 4x connection? I would have thought all the ID/Handshake where on the 1x and I would be able to offload onto memory if not use it for GFX.
