Hi Brian,
We can use the ESS if you like. The motion card to me is a little
transparent (mach 4 is hardware agnostic). As long as we can
support the reading of encoders we can make this work. If we did
Ethercat I could look at the current and make it basically a
Cobot. We could sense the current and kill motion and stop on
quickly increased loads.? May be a bit much for what your looking
to do but we really can do anything ;)? . Closed loop steppers and
an ESS with the encoders going back to the ESS so we can see the
position, I think is about as good as it is going to get for a
minimal investment. You will be able to move the bot to position
manually (you will need to make some sort of way to counterbalance
the Z axis) and teach it positions . Jogging for a use case like
this just to slow. I want to move to position and hold the head
where I would like to weld and press a button to set the positions
to weld . Simple and fast is what I am looking for. This may just
be me, but when I pick up a welder and start working I am not in
the mood to be a programmer. When I am in welding mode I pull out
the C clamps and hammers ;) CNC machine should be as useful, if
not... it's a fail!
Greetings
(I think I am getting confused as to 'which' Brian I am addressing but - - - )
I have only briefly looked into Ethercat.?
Would you please direct me to some resources? so that I could better understand Ethercat,?
including its benefits and negatives.?
I have further questions on this - - - - maybe this should be broken into?
a new thread? Argh - - - whatever - - - please for the info?
