Chad,

What I was thinking to do was do move then use and m code to check where the encoder says the position is, writing over the position dro and doing the move again. None of the errors in positioning should be very great on 1 small move but the accumulated error over the full length could be great.

As you are thinking about incorporating Mach in your product you could become a license re-seller and should contact NFS directly for that reason. Since you may be responsible be for selling Mach4 in some quantity it would be in NFS's best interest to assist you in your search for programming assistance.

Bill, That's true.  I didn't figure the error would be very much if there was any.  That's why I suggested the closed loop system. 
But it shouldn't be very difficult to run an error check macro after each move.  If expected position is not correct, adjust position.  If it is incorrect, then it will need to know to finish the move.  Issues arise, but they can be overcome.  I would still look into the HiCON Integra.  It may be a much more efficient way to be sure it is in the correct position. 

MN300, not a bad idea.

It seems like to me that the most difficult part of this deal would be programming the decision making part of the channel letters into mach 4. Going from "I want the letter F in this font and size" over to Gcode is likely where all their custom programming is. Mach 4 can easily handle the motion control and I/O (probably even the encoder error checking), but writing scripts to interpret a simple customer facing graphic interface where the letter, font, size, and quantity can be input would be a tremendous task.

If there is already other software doing this, then it seems like Mach 4 would be a perfectly capable candidate. If not, Mach 4 likely still has more than enough capability, but it will not be an overnight conversion and would require someone with intimate knowledge of LUA to program it.

Your customers will expect a product that will be supported for years to come. This means selecting a hardware platform that will be available for the life of the equipment and software that can be maintained by your service organization.
Once you have the software customized you probably shouldn't upgrade the Mach version unless it adds something to your product. Multiple versions in the field could be a problem.

From memory Delta Tau was taken over by Omron.
I am surprised they have left you stranded.
Have you talked to Omron directly?

Regards

Sounds like a job for an automation specialist and a PLC on some of the machines. Omron makes a good product.
