New CNC 24 BIT

·This is a project update of the SX 3 Axis Controller.
·This is a 24 bit version of an earlier project in the forums. The reason for the upgrade was to extend the accuracy boundries and the loss of the source code due to hard drive loss.
·The controller is set up for three Gecko Drive G210 Stepper Drives, Step and Direction inputs are used with 24V power supply.
·The inputs to the Gecko are 5V but opto isolators were used anyway.
·The RS232 converter is an ADM233 connected to pins D0 and D1. D0, the input pin, is high until a receive level is detected. This means during simulate D0 will need to be toggled or the program will jump directly to the serial subroutines.
·The VB program is included for the computer interface. The Linear Move Packet is shorter than the others for reduced delays between moves. It is possible to skip the Cordic for circles using this update if your circles don't have to be too fine. One could emulate the move with the software.
·The Cordic is a little jumpy when dividing a circle by 2PI * 1000000 Radians, may need some attention.

···· The source code will follow.
·I'm on dial up.

1. One click Auto Center will center a project to·a mills &h800000 center points.
2. How about some pictures? Yes, there are some pictures coming.
3. Resize by percentage. (Too make it fit)
ToDo:
···· Start from line?
···· Direct X simulation.
1.····· Resolved Cordic circle and linear move inaccuracy using Gecko Drives.
2.····· Streamline graphics to VB utility.
3.····· Photo’s of prototype and projects.
