Emco 120p Control hardware suggestions

Well yes that was my idea too,

i have been looking at ASRock Q1900B-ITX and ASRock N3150B-ITX. from what i have read the ASRock Q1900B-ITX seams to work with LinuxCNC but i have read some issues people have had with not receiving the input signals from a simple DB25 BOB, solution seams to be pull up resistors on the input pins on the BOB.

are my suggested boards a good choice or are there better alternative the is still available? will the DB25 port on the ASRock Q1900B-ITX work with MESA cards if i choose to upgrade in the future?

Sorry to burst your bubble but threading is usually done at much lower speeds.

That's the point, 1000rpm is plenty fast enough.

Exactly! I know that 1000rpm is very fast for threading, but all i wanted to say was that with a 1000rpm limit i will have no problem for threading and such!

On the computer note i noticed that Mini-itx.com was UK based and that made me a happy camper (No import taxes to Sweden, for now anyways) i used the board finder and the 12V input was a nice feature, i looked at this board: Jetway JNF9T-2930

Will this board give me any benefits compared to the ASRock? (except the 12v+ input which is nice!)

Well, actually, threading works better, for metallurgical reasons, as fast as you can go. I have done manual threading on a lathe at 900 RPM, and often do rigid tapping on my mill at 1000+ RPM. Surface finish looks like a mirror, while I get tearing of the threads at lower speeds.
