Hi all,
Looking for some additional help trying to get a mill running. It's a Centurion 1 with Partner 0/00 controller. The machine sat for a few months last year and killed the CMOS battery. I have another thread on here asking about battery replacement. I still haven't gotten around to replacing it but up until a few weeks ago I'd been able to use the machine.
It went a little like this:
Turn on power switch on back.
By the time I got around to the front of the machine, it'd say something about the CMOS parameters and "Press [F1] to Resume".
Pressing [F1] would take me to BIOS screen.
I'd press [Esc] and exit without changing anything and it'd continue the startup routine as if nothing was different and I'd make chips.
Now, though, if I let it run through the routine after exiting the BIOS, it goes through the creation of the RAM drive, extracts the files, runs the CNC pogram, asks if 3- or 2-axis, and then dumps me to a DOS screen with an error that says "Invalid graphfile path".
I can get a little further by entering the shell menu after exiting BIOS and altering the paths.
That procedure goes like this:
Turn on machine.
[F1] to enter BIOS.
[Esc] to exit BIOS.
Press a key to enter shell before timer runs out.
[F2] to setup SRAM.
Press [1] for all questions (format, create directories, default parameters, default paths).
At this point, the procedure deviates from what the manual says. I don't get asked about ball screw tables or if SRAM should be set up.
After formatting the drive, it puts me back to the shell prompt.
[F5] to change paths. I change Graphics path to C:\
Press [Esc] to start CNC program.
It extracts the file as usual.
Press [3] for 3-axis.
At this point, it says "Floppy drive failure; Reassigning graphfile path. Press any key to continue."
After I press a key it says "Your parameter file is corrupt (PFILE.DAT). You should load a backup pararmeter file from disk. Press Y to continue". One problem with this is/was that in the shell, there is no option to copy the parameter file to floppy. I do have the sheet of parameters that came with the machine, though.
If I press anything other than [Y], it dumps me to a DOS prompt and says "CNC session done. Power down CNC to restart".
If I press [Y], it begins the CNC program and the control screen comes up for just a moment. At this point, it dumps me to a DOS prompt with a bunch of error text. It says more than the following but this is the important part (AFAICT):
CNC halted: Error 200
Divide by zero

I have to assume this is because of something set in the parameter file and was wondering if anyone knew how to get into the parameter file in order to rebuild it. The DOS "type" command didn't generate anything useful. Another thing I'd like to figure out is why the SRAM setup doesn't ask me about blanking the ball screw tables.
Thanks for any guidance,
AP
