Are you looking for a finished and polished solution-provider, or do you want to do some of the work yourself?
A complete solution-provider would be someone like Scape Technologies. I have worked with them on bigger projects, but they also offer standalone off-the-shelf solutions.
Another solution could be to reach out to the robot manufacturer, as most of them offer solutions for this. This does require a lot more work to implement though, but is of course cheaper up front.
Contact Yaskawa support, and report the problem.
If it's a known issue, they might have a work around.
If it's not a known issue, all you can do is to cross your fingers, that they decide to fix it in the next version.
There are companies that specializes in developing prototypes and can work as sparring partners on product-ideas.
Try looking for companies offering such services in your area. This is not cheap though, but first meeting is usually free, and will get you an idea on how viable/unique/valuable your idea is.
The alternative, depending on the complexity of your idea, would be to try find a local Maker space in an area near you, most have equipment you can borrow, and some offer consultation for idea-development.
Good luck.
Yaskawa offers training in their facilities, both in US and Europe.
I've done the training in Frankfurt, and it was quite good - they have lots of different robots and equipment, and they offer training specialized for welding robots as well.
They had real welding robots with all the necessary equipment, as well as cells with additional external axis.
I would recommend contacting you local Yaskawa rep, and ask for details.
This sounds like a calibration/mastering issue.
Does the robot follow a straight line, if you run it along an axis in WORLD coordinate?
Is there a reason why you would not just send over the coordinates as data using PROFINET communication?
Declare 6 x 10 REAL variables, and a few BOOL signals as flags, to check if values have updated.
Robot check flags cyclically, to see if variables has been updated, if so, use REAL values to create a E6POS, and start motion.
Forgive me if I am missing the point of your question, but I am genuinly curious, what advantages does transfer by text-files have, when PROFINET communication is available.
Is there a reason why you can't connect the switches in series?
Another this is: Are those limit-switches safety rated? If not, they should NOT be used for safety.
When I was at the Yaskawa training academy in Frankfurt, I asked the exact same thing.
Was told there was no such parameter. It has to be set from the TP after every reboot.
Are you trying to control the robot using physical I/O signals? Ethernet commands? FieldBus protocol?
There is an Option Package to communicate with the controller using TCP. A bit complicated, if you are not familiar with "regular" programming, but depends on how advanced you want to get.
[...] I thought about a touch screen but not sure if this would work or how to connect it. [...]
I would be surprised if you can get this to work.
I'm not sure if it's possible to connect a mouse input to the controller, and use it as a pointing device.
Have you considered connecting the controller to WINCAPS, and doing your business through the software? Or is there a specific reason you want a clone of the teach pendant? You can do everything, and more, through WINCAPS.
