Within next few weeks I expect the delivery of torch, so that is when
I hope to start welding. Before that I have a time to finish attaching

1mm/min is 390 in/min.

Ok, thanks! I will report back, when I will try to compile these
changes and test on simulated arm.

You also need to do the 1 to 1 conversion of jest back to joint in the

Those are steppers and title of video says - arm for a welding robot,
so I suspect, that it will hold the welding gun.

Did you get genserkins working with sliding joints?

I'll be very interested to know if there is any chatter at the end of the
arm during the welding process.
Great design!

What do You mean with the method of heating?
If You mean - what kind of welding is that going to be, then - it will
be MIG welding machine.
Power source,
Very nice. Can this arm survive welding and its shielding/interference
issues?

Hello guys!
I decided to share a small preview on a robotic arm that I am building:
http://www.youtube.com/watch?v=9olpU79H0o8
It is still a work-in-progress, but the first stage of getting arm up
and moving has been completed.
