During the process of building my OpenPNP machine I decided to get my new feeders working with the RV. I have jobs I still do on it and it's only the feeders that presented the biggest issue to me. Waiting for a few bits of air pipe and couplers but the mechanics is done and the electronics.

Hopefully will be testing it by the end of the day

I bought a CL feeder a while ago to look at - would be interested to see your mounting details.

I originally got a aluminium plate machined but they made it wrong and I did not want to wait weeks for a new one so I tried a 3d printed variant and it seems to work.

The image on the printer shows the main body and a thin plate. The plate holds an o-ring in place which makes a seal when the feeder is mounted.

I used a brass inset to create a thread for the push fit air inlet.

The body is bolted to a 2040 piece of extrusion which is mounted to the RV bed.

Hmm - I just did a teardown of some biotech gear with 20 solenoid valves inside, could come in handy....

The cl feeders seem to work really well. They take up more room than the versatronics feeders though. I am considering having a standard Rv feeder for common 8mm paper tape values and then use the cl feeders for job specific values that need changing more often. Least for now anyway.

It seems you can create an Rv feeder with 16 lanes. I was thinking to create bank A or B as a 16 channel feeder for the CL block. The custom electronics will take care of index count for 12 and 16mm tape components so that all lanes can have a default index count of 1 in the Rv software.

The other thing is for the cl feeders to work with rvs they need air to them all the time and then a quick pulse to close off the air to move the tape forward one index.

Happy to share stl files if anyone interested in them.

Quick update. I found the seals were not good enough and needed to buy some better sized orings. Also the plastic strip that held the orings in place did not seem to be good enough and I was get air leakage.  Maybe not flat enough being printed. Luckily I had a metal version which I had originally ordered when I got a cnc part made. That seemed to seal really well. It's possible the plastic part can be designed better but at this point I am looking to get a reliable solution first.

Will update again in a few days once I have done more testing. I have a production run to do and I think it will work fine. It will be a good test for it.

Getting there slowly. Ironing out a few things but cl feeder is working.

Today I pushed through with an actual build. I did 1900 components in total and the feeders worked really well. This was a mix of paper and plastic tape. They all worked great.

I am trying to figure out how to document the build as it got quite involved. I might put it all on GitHub and provide a link.
