Hi guys, my name is Juraj, i come from Croatia and this is my first post.
I have decided to build mpcnc and now i need some equipment and size advices.
I have sourced most of expensive hardware and electronics from china for around 150$ but i still have no idea what spindle to use.
I would like to have enough power to make complex parts in aluminium blocks, but i also plan to use machine to cut wood, acrylic etc…
I found this spindle and it is within acceptable price range (with shipping 150$) but i don’t know if it’s too big or too heavy for mpcnc.
How much power is enough for good aluminium cutting ? I dont want to overkill it…
From there comes my another problem… what size ?
I know there is more flex with bigger machine and that may not be problem when cutting wood but precise cutting in 5x5" aluminium block on 1.5 x 1m (5x3ft) machine seems like a joke to me.
Any advice regarding max work area of machine so it can remain very precise. I would like to build 5x3 ft machine but i will sacrifice work area if it’s needed for precision. Stainless steel conduit is being considered, i think it is alot cheaper in Croatia than US but i still have to check that. By the way, what wall thickness should i look for ?
One more thing. What is considered to be standard cutting Z-hight ? I would like to have Z-axis as high as possible but i don’t know what tehnical problems come with that .
Thanks in advance for all your help !
