Hello all, I have chosen most things I need to put my X3 conversion together! Thanks to everyone who has helped me out so far. I do have some additional questions regarding electronics.
I have seen people talking about other electronics in their CNC builds, other than what I normally see. These include, Smoothstepper, master control board, spindle control board and boards for coolant.
Are ANY of these boards NEEDED to run CNC? Is all that is REQUIRED, the stepper motors, stepper drivers and the BOB?
IF they are not needed, what are they used for? I assume the spindle control board can be used to change the spindle speed through mach 3, but is this necessary, or can you just manually change spindle speed by pulleys, etc.
Also I would like to have the capability to have my computer control my coolant, what do people recommend?
LASTLY, as far as limiting switches go, do you need 1 per axis, or 1 for all 3 steppers?
I realize this is a lot of questions, but any help is greatly appreciated!
