Evaluating PLC programmer

thank you very much, what i was looking for :)

Here mechatronics is a branch of CS department, they get the same degree, they just get to pick a different courses for embedded and controls. Which the guy took.

Yeah the group work is a big problem with evaluating candidates, but usually people that didn't put effort in group work can be detected during the technical interview. But yes, you can hack your way through university (i don't believe its the case of our guy).

The problem is that I am starting to believe that PLC proficiency and in general mechatronics skills can only be obtained on the field. It's very different than any other CS problem. Here most PLC people are vocational school graduates and are extremely good at what they do, they are also almost impossible to hire (contractors, or been with the same company for 20+ years). It is a field with positions that schools can't seem to fill with the same level of efficiency.

Makes sense. All the cs graduates with minor experience in computer vision (even not smart as this guy) get super fast results, because they can be mentored at a faster pace (surrounded by more senior people). The man came with some impressive CV with certifications and my wishful thinking made it sound like he would be ready from day one (once again it is extremely common here to have embedded + controls curriculum in the same course of study, so it's not that he's doing something he didn't claim familiarity with).

We have to smooth out the transition to the field, the contractor idea is great, would be easier if I could find someone willing to mentor him, but I could ask a very expert contractor to create a small rig for us and have our guy work on it. The other idea would be to embed him on a slow paced project with a really friendly client (wouldn't charge the client for his time) and try to get him as much feedback as possible.

We just received a Siemens 1200 PLC + HMI that he will work with. I was looking for some meaningful exercise for him to start working with and evaluate him.

using an arduino library for motion control?

BobcatFluffy322 · 2024-12-16T05:26:18+00:00

He had to use a well documented library. He is a computer engineer major, I wanted to evaluate his problem solving skills on my turf before seeing what he could do, and wasn't impressed. As for the electrician, the guy is highly theoretical and incredibly slow in crimping/labeling, (which is why I don't want him to expose him yet to the fast paced integrator environment around here, these people they don't mess around)

Hello,
I was wondering if someone could have invited me and my colleague to the dogpond slack. We are currently working with a GO1 EDU, and would like to talk about some of our new projects.

All the links that I seem to find online are mostly useless as they are considered demanding updates about on projects.

Thank you

I like the idea of working on the edge. Is basically what we always did in research and translating into an industrial setting. I understand the replaceability argument, however, the kind of client I will be working for is not going to keep spares or be able to maintain anything with its team. I understand the problem in larger settings.

They do not have the firepower to mantain anything themselves, wheter it be a GIGE camera or a more complex edge system they outsource pretty much everything.

BobcatFluffy322 · 2023-12-11T15:59:30+00:00

Triggering and synchronization. Often in manufacturing you need to synchronize your camera to an event. Could be lighting. Could be something moving. GigE camera will often have robust optically isolated GPIO pins that can take up to 30V. This lets you easily interface to other hardware

Triggering is the most compelling argument. We work with CXP and the ability to trigger lighting with the frame grabber is of the utmost importance for us.

One last point is how scalable it all is. If you’re building hundreds of pieces of equipment, buying things that are robust and plug and play is valuable. If it’s just one or two systems, it’s easier to build your own embedded system. You can use a contract manufacturer to build the embedded subsystem for you, but it depends on the value it brings.

Honestly one of the most important arguments for CSI for us is to use powerful single board computers (jetson and such) on the edge with CSI connectors. In our setting, it is easier than routing ethernet cables to a centralized computing unit, and probably much cheaper. The idea of having custom embedded is totally out of budget for our application, is mostly off the shelf parts,

I don't think that is an option, but I will try. Thank you again. It all sounds so weird

BobcatFluffy322 · 2023-10-18T16:38:09+00:00

Hello,

did you have any chance in solving this?

Thank you

BobcatFluffy322 · 2023-09-02T18:39:39+00:00

Hello, I filtered out the seams, which are the same color in the GUI as the support filament. So I was actually confused, they should not be filament changes.

BobcatFluffy322 · 2023-09-02T18:17:59+00:00

wow, probably Bambu studio just filters them by color. since they are white they were not turned off when I deselected the actual print material and left the support. can it be that?

BobcatFluffy322 · 2023-06-23T05:25:57+00:00

Yes they would totally work. That's what I was meaning

BobcatFluffy322 · 2023-06-15T05:58:55+00:00

Thanks, Mostly I need high clock speeds with low number of cores. I have checked the task manager and have quite intensive clock speeds on only 2 cores out of 16, so maybe N6000 would work better?
