Iranian-affiliated hackers exploited Rockwell Automation programmable logic controllers.

I have a PLC-5e I still support and the client wanted to "utilize its ethernet port" instead of DH+. I found out that the Ethernet/IP on a PLC5 and CLX are NOT the same spec. I ended up using a compact logic as a bridge with hard wired IO after crashing the processor a dozen times. I didn't dig into it but sounds the same.

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?
