Art,
I am interested in the 2d interface your working on for plasma. I have
another use for it that is similar. I am building a waterjet system. It will
be a gantry with 2 motors on the Y axis (6 ft travel) and 1 motor on the X
axis (12 ft travel). I have most of the parts gathered up and the 6' x 12'
water tank completed. The pump & cutting head are ready now. I am just
starting the gantry. I have ball screws with antibacklash nuts for both axis
connected to Glentek servo motors. I am enclosing the linear bearings and
the ball screws with bellows, so nothing is exposed to the grit and water
spray. From the work I have done with waterjet and with oxy-acetylene
cutting, one of the most important features of a control is the ability to
look ahead, decelerate, travel around a corner and then accelerate away
from the corner. This becomes more and more important as the thickness of
the material being cut increases. It would be very nice to be able to
preview the cut and then be able to set the speed for different sections of
the path by pointing and clicking. Another important feature is the ability
to rotate the program to match the orientation of the plate on the table.
When a very heavy plate is placed on the table, it is very difficult to
align with the axis of the machine, so the program needs to be aligned with
the plate. Let me know if I can be of any help.
