OK, so will whipping still be an issue with 2no. 1610 screws at 1500mm long - as they will still both sag? Jonathan have you drilled your housings with a holesaw? if so can you recommend a make, I bought some makita ones a while back and they are rubbish.
Also what are the implications when buying drivers if you are going to add another stepper into the mix later? (I was thinking of getting the electronics from http://www.diycnc.co.uk by the way)
I do want to be able to cut more than just ply! everything from aluminium/ply/mdf for furniture making to paper/card with a drag knife for architectural model making/graphics. not sure if I am being unrealistic as I am sure one machine can't properly fit all tasks?
Apologies for all the questions!

They will just about be ok but will need very carefull alignment has any miss-alignment will be exagerated at high speeds and this is when whip will occur.
I have a Bosch quick realease hole saw and it's brilliant, not cheap but good.
No problem adding at a later date but does need a bit of initial planning regards PSU to workout best way and reduce cost's further down the line.
Regards DIYCNC then personally I'd say no because he doesn't do any drives powerfull enough for what you'll need to get best performance.
My advice would be buy individual drives and pay the little extra and get 80V drives with 60-65v PSU this will give you the best performance for the 3nm motors your going to need to drive this machine.!
Then absolutly 110% go with twin screws from the get-go.!!
No need thats the whole point and why where here.!!Last edited by JAZZCNC; 26-04-2012 at 10:55 PM.
