z axis side plates on...
I've been lurking for quite some time. Always wanted to build some CNC stuff. Many years ago I etched my own board for the MM2001 controller for a foam cutter. Built the board, had the steppers and all... never got to making the mechanics. Long story short, I traded that stuff to a friend who finished it up, so now he has a CNC foam cutter in his shop, and it's quite handy.
But moving on to current times, I have always wanted a CNC router as well, for making all sorts of stuff, but mainly for the model airplane hobby.
So I've looked at loads of designs, and poured through thousands of posts, and settled on the Solsylva 25x37 machine. I'd love to do a nice 80/20 aluminum one, but that's just not going to happen at this point in time.
The problem I found with most of the designs out there, was size. While it would be nice to have a ginormous table, I don't have the room or money. And the small ones were too small.
I picked the Solsylva because it appears that with minor modifications, I can lengthen the X axis to where I want it (in this case the 49 inch x footprint will be growing 11 inches).
I also want to start off with better lead screws, so I'll be using the 1/2 10 5 start ACME as recommended.
Being new to the big picture of all of this, I also need to get used to fiddling about in 3D cad, so I figured the smart thing to do would be draw it all up in CAD and make sure everything fits with the changes (lengthened and bigger ACME screws)...
So I got started drawing pieces...
Very nice start Arbo,
I can see that you will get into this build and enjoy it.
When you make the legs you will need to move the lead screw hole away from the frame about 1/8" to accommodate the larger lead screw diameter. I didn't do that and had to chisel into the frame 1/8" to fit the bearing blocks in place. A similar adjustment will be needed at the gantry for the lead nut mounting.
I also made the front board double thickness because I thought I may eventually drive the lead screws with two steppers. It was a good thing to do even though I'll never do that change.
Which CAD program are you using for your drawings?
On the Solsylva site there are other oak machines in the customer build photo section that may give you a few more ideas.
I'll keep the double front board in mind as well.
Nuts and bolts for the trucks made, need to make the bearings and finish putting them all together.
Y Axis trucks built and put on the carriage.
Z axis trucks made and in place... (yes, the holes/bearings in the aluminum are reversed, but not going to change it just for this drawing )...
Z axis installed on gantry...
Really nice looking CAD work you're doing Arbo. Keep it up.
Will do. Just going through the plans/instructions now making notes. Silly things like .5 ID bearings for the ACME bearing mounts and such.
Did you use the 1/2 in the Z-axis as well?
Y gantry end plates on. Stepper mount and shaft holes moved back 1/8" to account for larger ACME rod...
