I need some help selecting steppers and the electronic components for my 3 axis machine.:drowning:
My problem is that I do not have much of a clue what the various specs on Bangood mean (or anywhere else for that matter).
OR what I actually require.
My machine is roughly based on the Solsylva design, X and Y travel 600mm, Z travel 300mm.
The lead screws will be M8 x 1.25 pitch (for now) hopefully directly coupled to the motor shaft using spider shaft couplers.
(No step up/down belts or "flexible ally couplers").
I intend using an UNO and Win7 PC to drive everything at this time so advice on what best to use along with the UNO would be appreciated.
As noise will be a problem I would love to use a high wattage spindle motor and belt drive an ER32 collet holder spindle to keep noise levels low AND so that I can use off the shelf tooling with indexable inserts.
Exotic max IPM feed numbers are not important and the material being cut will be various woods but later I would like to upgrade to proper multi-start lead screws.
But this is for another time.
I will probably have to start out with a router and bring the speed down to get it quieter, and of course the M8 threaded rods.
So what would be the most cost effective motors (listed on Bangood) to use?
What UNO "shield" should I use or should I use separate "stepper driver units" and if so, which ones?
(I presume that using "stepper driver units" will mean that a "shield" is not necessary)
One day, when I am feeling REALLY BRAVE maybe moving over to Mach4/Linux will be considered but not just now.
I have had CNC shop experience (Victor 2000 with Fanuc controllers) but the "home grown" scene is totally new to me.
Looking forward to finding out what everybody thinks.
All the best and thanks.
