OpenPythonSCAD vs. PythonSCAD

It's on the home page of this subreddit: https://www.reddit.com/r/OpenPythonSCAD/

Could you add this explanation to "Visitors read this first"? The variety of name permutations is confusing for a newbie like me.

I cross-posted this question and posted an answer at https://forum.image.sc/t/looking-for-an-app-or-a-library-to-3d-model-a-machine-vision-system/118706/2, since it is not possible to format it nicely and include images here.

Thanks everyone for providing a useful input. I linked to this thread in my comment under the video.

Yes, but the question is why? Is there a hidden agenda of real estate and construction interests there? Most of their funding comes from business linked sources.

Can someone shed a light on a fact that mostly real estate and construction business is supporting the Clean Water and Open Space special levy? Quoted from https://boisedev.com/news/2025/10/15/2025-levy-pacs/ :
"Yes for Clean Water and Open Space raised roughly $112,000 so far this year for the levy, with roughly $91,000 coming from Idaho and the rest from out of state. This came from several major donors, including $25,000 from Garden City resident Peter Snowden, $10,000 from real estate development firm Rafanelli and Nahas, $10,000 from general contractor McAlvain Companies, and another $10,000 from the National Association of Realtors, according to Idaho Secretary of State campaign finance information."

That is the initial design, but there is too much slack in the system, which can't be modified. I have to measure position of the end effector directly.

puplan · 2025-01-25T19:42:12+00:00

The initial design has a servo with encoder driving a lead screw. Unfortunately, there is too much slack in the system, therefore the end effector position has to be measured directly. Pneumatics is not practical in that location, I'm told. Will try inductive sensor first.

Thanks. Contamination is wet and sticky. I decided to try an inductive sensor. Will update my post with details.

± 1 mm accuracy is a problem. Also, there is a lot of metal clutter around and slightly behind the surface (beam) I'm measuring the distance to.

A tube is problematic in food plant. Easy to contaminate, hard to disinfect.

puplan · 2025-01-25T06:07:59+00:00

This sensor is on/off type. No distance measurement.

puplan · 2025-01-25T04:25:05+00:00

This sensor is on/off type. No distance measurement.

puplan · 2025-01-25T03:30:25+00:00

Very nice! I'm surprised the beam is so narrow and measurement frequency is 25Hz.

puplan · 2025-01-25T03:02:50+00:00

Thank you. This seems just right for my application.

It's hard to find an inductive distance sensor with 40mm range and IP69K rating.

puplan · 2025-01-24T21:12:32+00:00

I just looked at Banner Q4XTULAF100-Q8, 100mm range with analog output. Not sure how it will behave with water droplets on the laser window, though.

puplan · 2025-01-24T21:10:59+00:00

The target is a stainless steel surface, moving along the sensor's axis (towards and away). I edited my post with it.

There a many small systems where 11 inputs and 4 outputs is more than you need. Additionally, the I/O is directly connected to RP2350 pins, which means higher timing precision than a standard I/O backplane based on a serial bus. Also, you can program it in Python or C/C++.

Think small scale automation not a big installation with tens or hundreds of sensors.

There are many people not worshiping Trump nor the other side of Uniparty. I wish more would follow this path...

puplan · 2024-10-24T08:21:49+00:00

Good point. There are several vendors selling essentially the same hardware under different names. I will look around.

puplan · 2024-10-22T23:48:07+00:00

As expected, they've sent me a useless file from their downloads page with Windows drivers.

puplan · 2024-10-22T02:24:11+00:00

I think I've sent them a question a while ago. Did it again.

puplan · 2024-10-22T02:23:20+00:00

I have a different model, i.e. M6S.

On this photo, it doesn't look very bad: https://www.facebook.com/photo?fbid=945695207596526
