I need some help,
A month ago I bought the motors, board, power supply and fan from xylotex.
They are now connected to a mini mill and are installed in a box with the fan blowing over the heat sinks. I have had what I think are over heating problems so I have been playing with additional fans (No luck) so I reduced the Vref to ~2.16V. This didn't help anything so I put the Vref back up to 3.35V. I was running a code I had run several times before (In Mach3). And as I rounded the corner (X axis decelerating, Y axis Accelerating) things just stopped.
The computer thought it was still going but the motors were not moving. I shut stuff down thinking it was an over heat and let them sit for an hour.
Turned the board on and nothing would work.
The current state is as follows:
Red power light is on
24V and 5V supply is verified at the board
Vref = 3.35 for all three axis
24V on each of the motor wires (This seams wierd to me, as two of them should be GND)
Motors spin freely.
In Mach 3:
Limit switches work (Pulled high and low), but I have two pins that seem to float (They are not assigned to anything right now in software)
Even when things got hot earlier, they were relatively cool to the touch, no more then warm water.
Thank you for the help,
Tim
