Ok will probably just go the messa card and rj245 route then I actually have another laptop i could use with I think 6gb ram not sure which chip it has I think it has windows 7 on it right now I will...

I do have two old desk tops laying around ok ne is Pentium 3 other is 4 but have no idea of how much ram they had I wouldn't think much

So another question what are we able to use with linuxcnc usb cable, rj245 port or are we kinda stuck with and older parallel port system cause of linuxcnc's ability

Thanks to all yes have some ideas

Guess that's a silly unanswerable question let me rephrase how much additional power do most of you use on a home base machine with a 2.5kw spindle and no vacuum table

I understand that would rather see the limits closer to you can't push that dia cutter that fast in that material weakness be closer to the strength of the cutter not the unobtainable federate or...

So looking at linuxcnc would like to go that route which distro of linux is best for linuxcnc debian, ubuntu. Install on hp envy i3 or 15 don't remember 1TB harddrive and I think 16gb ram. So I see...

So maybe ideally I would want to try and match spindle with federate a little better and shoot for maybe 500 or 600ipm federate to take advantage of the spindle rpm and torque better when needed...

And here's the other thing say I go with Jianken 2.5 kw spindle what can I expect for cutting depth and speed in say hardwoods, plywood, MDF. I mean if the spindle can't cut at 350ipm and a decent...

What I really wish is the someone in US would distribute Chinese routers as bare bones machines with quality linear rails and helical racks with a lubrication system in place and you just add the...

So was in my mind thinking 25 to 30 mm dia ballscrew and probably 25mm linear rails now going with the helix rack and pinion very well maybe and option hoping I can weld frame have it stress relief...

Servo in that price range sounds possible not sure what size best fits a router for cutting hardwoods, plywood, aluminum and never steel. I know almost nothing about calculating inertia and sizing...

How much additional power will I need for controller and steppers ? not planning on vacuum table but was more or less hoping to be able to run the air compressor off of that other 30amp 220v circuit

I actually have two 30 amp single phase 220v circuits available and several 110v 20 amp circuits

Really like the ballscrew idea better. The other thing is most of these steppers don't talk about how many rpm's they turn or show you a torque curve related to the rpm's. Would rather use a 10mm...

Yeah I've seen a lot are using helical racks fig that would be a lot better. What if a guy used say 25mm lead ballscrew then only need like 500rpm to get to say the 500ipm rapid moves. But assume you...

Designing cnc router approx 32 inch y axis and 72 inch x axis. So I know most will say go rack and pinion cause of ballscrew whip I understand this so guess my real question in a rack and pinion...

Could probably go to 3.5 kw spindle max with this setup sorry meant that instead of 3.3 kw so from what I'm seeing on your reply this vector drive and up to say a 3.5 kw 220v spindle would be right...

Could probably go to 3.5 kw spindle max with this setup sorry meant that instead of 3.3 kw

So if I'm looking at things correctly this vector drive and a 3.3kw 220v spindle would about max out that 30 amp single phase circuit. Is this correct ?

Found this vector drive which I believe I read you must go bigger if only single phase input so would this work good for that spindle on a 30amp 220v single phase circuit ...

How much psi and cm needed for tool change operation and what is the best affordable option for delivering clean dry air to it

So just starting to consider building cnc router looking at spindles seen Fox3d review of the Jianken 2.5kw atc spindle right now is my first choice what else is required to operate this spindle...
