We are running a Retrofit CNC Bridgeport that’s a bit of a Frankenstein.
We have a Windows XP PC Running Mach 3.
The Steppers are controlled with an old Flashcut “BlackBox” made by Anaheim Automation that’s just the Stepper Controller. It’s a serial port connection.
Also, the Serial Cable has been modified to allow Mach 3 to control the black box instead of the FlashCut CNC Controller it probably originally came with.
Today we disconnected all the wires, the PC, Steppers, everything, to clean behind the machine and do some wire management.
When we reconnected everything, Mach 3 no longer moves the steppers. The DRO in Mach 3 moves but the steppers don’t.
The stepper controller has 3 green lights on for each axis (no red fault lights) so I think the black box is fine.
Nothing in the Mach 3 settings were changed so I don’t think it’s Mach 3.
Which only leaves (in my mind) the PC Serial Port, and the modified Serial Cable as potential culprits. When I go into the Device Manager in Windows the LP1 port (I think) is functioning correctly according to windows. We did a continuity test for the pins in the serial cable and no breaks were detected.
Which only leaves (in my mind) ???
If anyone has any ideas, please post them. Tough part of the season to lose the CNC mill. Thanks in advance.
