You can load a full sheet into the machine by inputing the size of the sheet and work backward by minus the size you need.
Sound quite simple but guess its not when you building a standalone controller to do this
please keep me informed on ang progress |
There's no guarantee that the unit won't be turned off. At that point, it's unknown exactly where the fence is. So on power up I would (on request from user) move the fence until it reached a home switch. At this point the system knows where the fence is because the operator has already calibrated the system that the home switch is at X.
The operator has also told the system what the maximum and minimum distances are relative to X.
To me working backwards from the sheet size is odd but I can understand why a system might work that way. The cut off pieces are in front and haven't dropped down into a bin.
Seems more logical for most non-production line applications to ask for a specific size and then have the fence move to that location. That's because the size of the piece of metal picked as raw material is unknown or hard to measure accurately (to the nearest 0.001").
For fixed size paper products I can see why it's done the other way. No reason the software couldn't address both.
