Oh yeah we also had a war with emus....and lost
This is true. I still remember scratching for gears in an old motorbike with old man emu snapping at my ass. I swear that long neck looked like a rifle barrel! All becasue I got a bit too close to his nest filled with her chicks, But heck I laughed the next day after I discretely ensured my brother followed the same line I had. Old man Emu was more than pissed by then. I thought he nearly had my bro!
LOL @ emus !
Here you can run have a run in with a bear and the bear will be scared shitless from nearly 10 years of trauma gathered from people shooting them on sight. Luckily that has stopped so lately they are growing in numbers.

I think I'd be scared shitless and traumatised enough to shoot on sight too!

deep digging some non-english forums and websites led me to a nice Cad model.
I think it's an Amada press brake. I will update with links for files.
What format suits you all. F3d or stp?
people with cad abilities can modify and update it.

My Amards is an upstroking (bottom folding) version. Controls look very simple.

A question. Am I right here?
I think there there are two option for setting the tool height
1) we use linear encoders along with ram.
2) we can use ballscrews on both sides which trigger endstops. When we need different height l, setter moves up or down.
Foot pedal triggers the ram down until it hits endstop and then returns up.

I think that for getting height you need to take linear encoder. If there is source of presure from few sourses, then you need linear encoders on two sides of press. Presure in each cylinder should be controled separetly.
Bottom side of press form should be one height. Up side of press form could be changable. It's height should be controlled with laser pointer with mirror that will give height of that pressform.
If press need to control only angle, than PLC is enough. You need to know only thikness of the material and bending radius.
It's m vision for this.

Thankyou for your suggestions @aleksamc
Controlling pressure separately is nice idea.
Can you some some examples of mirror and laser thing?
Cheers,
Pinder
