Thread: Initial Design Check Please
Thanks Jazz, ive just redrawn the lower frame and the bed but just need to finish a few bits before i post any more pics up. Ive ordered the prox sensors.
Hi Jazz, ive redrawn the bed its now 20mm thick with a box thats 25x50 surrounding it.
Better but will be difficult to achieve and be good enough. Far simpler to just make box section frame and sit the Bed on top then just use Thin sheet to make a surround for containing coolant.
Also how you going to drain and filter and remove coolant/chips because that box will soon fill up with chips/coolant.?
Hi Jazz, thanks for the reply. Ive altered it and hopefully im getting there. I am planning on using thin aluminium angle to build up a shallow surround. Im planning on using mist cooling and not flood.
With regards to electronics what kind of steppers do you think this cnc will eventually require would it need the 3.1nm or 4nm stepper, only reason im asking is to check the stepper space that ive got for the z axis stepper?
Hi Jazz, does that look ok, the t slot plate will be bolted directly to the adjustable steel frame. Then gutters can be added to the steel frame if im going to be running coolant or not, these will be just aluminium angle.
Thanks again Jazz, ill update it. I cant wait to start the build, especially when you look at the build logs on here.
Well small update, ive started building the top part of the CNC with alot of help from a close family friend.
Here is a few pics of the progress.
Starting work on the spindle brackets
Main gantry uprights and bearing plates
Gantry bearing blocks
George and i on the Miller building the spindle plate.
With regards to the steppers for the machine, would the 4nm or 3.1nm steppers be best? Im im thinking 4nm ones from cnc4you and am882 for the drivers. I wont get the drivers yet as i dont require them just yet.

I was disappointed to see the discussion about steppers - from the earlier pictures, I had hoped that this would be the first steam-powered CNC machine!
