Re: [CAD_CAM_EDM_DRO] Re: Motion Control Software for independent axes

Don't forget just basic automation practice. Alot of this automatic motion could be controlled with limit switches and actuators independent of the software. Ex. Table rotates, hits limit, cancels ratation, another triggers software, operation completes, last action retracts, hits another limit, program ends, rewinds, table rotates, hits limit, triggers routine, etc. Some motion can be indepent of control. Providing that motion is triggering the logic.

Thanks for the quick responses! I am checking into these suggestions.

My application is an assembly machine based on an indexing table
(servo-driven indexer). Separate assembly motions are performed at
each stop position of the table. These operations have a total of 5
steppers. The control software will synchronize the movement of the
table and the different operations. Total of 6 axes to control.

I use CNC Pro and have used/looked at a few others. They work for my
separate operations but not for overall machine control. I like how
TurboCNC handshakes with PLCs for starting and stopping operations,
which is needed here. But unless I'm missing something, these
programs won't allow me to have two or more motors running on their
own commands at the same time without "interpolating" them together.
One motor may need to stop, start, reverse direction, or change speed
without bothering the other.

With all the great software out there, I'm hoping there is something
available (and affordable) that will work without the need for too
much custom programming.
