I checked the XT PC which has 2GB Ram and Dual Processor Pentium.
Loading a 91 meg G-Code File, it took awhile using 53 to 65% CPU, however after the file was loaded 4Axis G-Code and run under Simulation it only used 0 to 1% CPU.
So this old XT PC is not an issue as the file has 5,249,274 Lines of G-Code in it this is larger the majority of Mach4 user will ever run.
I am not sure how it would run with a controller, but at this stage do not see an issue.
I also tried a 5Axis Simultaneous G-Code file and using the WX6 Screen, however after loading Mach4 came up with the following message "Vertex Buffer Objects requested but not available".
An incorrect picture appeared not representing the G-Code on the Screen.
The Mach4 would then not run nor close down so there are issues here.
The are many users out there that have XT PC's on there Mills and Router Tables that want this program Mach4 to fully function.
Also if it does work then I am sure there will be many new users with XT PC's wanting to use Mach4.
