Hello JT, I hope to be able to respond promptly to your email. Why don't you use LinuxCNC?
Will I be able to see your machine online, running with your Ubuntu?
I think, LinuxCNC 32 Bits, isn't it more complete than your Ubuntu with LinuxCNC? I made a small mess of talk, because I wanted to use my 32-bit HP Mini, but it does not offer me a parallel port, and it is the one that distorts my image when booting LinuxCNC 32, it did boot Ubuntu correctly and hence my talk.
But I have forgotten the parallel port that the School's LinuxCNC 32-bit cpu offers me, which I have installed on the old 32-bit cpus, with 512 megabytes of ram, IDE mechanical disk, and I loved how fast they were, fluid, that I even installed games on them, to stimulate my students. So, if the 512 megabytes of ram work very well in your Ubuntu, in the 32-bit LinuxCNC, do they also work well? Or do you need more hardware? Thank you very much!... Congratulations!...
