Mach 3 : Windows 7 vs previous OS's
« on: March 05, 2015, 05:25:39 AM »
Hello there :)

I'm currently using Mach 3 Demo for testing on PC & Laptop.

The laptop has Windows 7 installed & doesn't possess LPT port.

The PC has Windows 98 installed & LPT port.

I've created a PCB project using Eagle software and tried running the produced
g-code on both machines. On laptop it has shows whole board and test runs went
smoothly. On the PC only a small part of the board was shown and only the shown
part was made (through test).

I thought that it might be due to the demo limitations (how does those work? My demo
on laptop was able to go through whole g-code with 5.5k lines. Does it only applies to
actual sterring the machine ?), but after installing demo on other PC with Win XP/Win 7, which
also has and LPT port, a little bigger fragment of g-code was shown on the display, but still
just part. Any ideas why wouldn't it show in display everything it should ?

Thanks in advance for Your help ! :)

Best Regards,
Sarachiel

Does it say Demo mode in the title bar? It should not be displaying 5500 lines in demo mode.
Your desktop is showing the correct behavior.

I believe that if the PP driver is not installed, the unlicensed Mach will display and "run" more than 500 lines.
This would account for the difference the OP is experiencing.

Hi there,
my understanding is that provided the computer cannot actually machine a part due to the absence of the parallel port driver or an active smoothstepper
connection the computer will display and simulate gcode files in excess of 500 lines. If the computer is capable of actually controlling a machine then
the 500 line limit applies.
