General Mach Discussion / old machine Pinout for Mach3
« on: July 28, 2011, 02:35:27 PM »
I am helping with a non-profit organization working on starting a Maker Station in Fort Wayne, IN. we were given an old retrofitted 3 axis CNC Mill which had "JeDi Cam" as the control software. the machine worked fine with the old DOS based control, but we would like to update to Mach3 if possible. I thought it would be an easy switch to Mach3, but after 12+ hours none of the steppers are moving.
this is all i know about the machine and controls:
it has a DB25 connector going in - the only pins i know for sure are Pins 18-25 go to "ground". (I have tracked most of the other pins to their respective PIC16C54-HS/P chips on the board, but not sure what is going on in the chip)
The circuit boards are labeled "J&S Products P/N 0373A"
the steppers are Eastern Air Devices Stepping Motors 3.1Volt, 2Ph, 5.0A, 1.8Deg, Model LA34CKK-2J, Date Code: 9435
I have reformatted the Dell desktop and only have Windows XP, Mach 3, MachScreen, and Adobe Reader Loaded
I have triple checked the Com port for Mach3, and have tried countless combinations of Pin #'s for the step and direction. without knowing the original pin designation, is there anyway to narrow down in mach3 what the set-up needs to be to make this machine work without buying a new stepper control box?
