Hi

Recently my Plasma Cutting Machine - "CR Electronic model E-3-15 year 1998" returns a error and don't work.

The problem is:

1 - When I go to "plotter" option on Main Menu and create a new project selecting a created geometry and optimization. Finishing that when habitually the printer on my desktop print the aspect and distribution of the cutting pieces now returns a error on screen and exit the program "PLASMA II".
The error is:

"Return time M6101 math Floating-point. error-invalid, 129 returned from PL to exel abort."

2 - If i go to "plotter" option on Main Menu and select "transmit" to transmit a previous project occuors another error:

"Plasma TX Error 7 in Function "rx_char", Called from:
"main","tx_start","rs_open",
Timeout Error. Check Connections."

Both completely disable the plasma cutting machine, because this is the only way to send information to the machine.

I try something to solve this problem but the problem persists.
- Install newer PC Printer "Epson" (it work, printed some program reports).
- Verify cables that connect PC to the controller of plasma cutter.

I presume that everything on desktop software still OK because it don't have internet connections or any contact with any other software. I only have MS-Dos OS and the Plasma controller program "Plasma II".

I appreciate any help to solve my problem, any information about the presented errors because any of them are referred in the Manual of the machine and any solutions to resolve or find the origin of related problem.

Thank you for your attention
