Steps per unit daft question

[cncJim]

Cheers for that Jim... Just reading through formulas and working out pitches at the minute :) mind bending!

Quite a good explanation here... http://rlab.org.uk/wiki/Project:Large_CNC_Router

That's very funny because that's my wiki page! :) I am a member of rLab (http://rlab.org.uk) and I use the wiki page to document projects and stuff and hopefully "inspire" me to maybe finish some of them!! Google really does get everywhere....

although it'll soon seem like common sense and I'll wonder what I was ever confused about!

Nah, if you are anything like I was (am?), you will file the information away somewhere "safe" and the next time you need the same info you will forget where you put it and ask the question here again! :)

Cheers,

Jim
