Yesterday I had a little extra time and so I ended up finishing my new spoil board. It was one of those rare instances where everything came together really nicely and no major mistakes were made. The new spoil board is 21.5″ by 21.5″ which is quite a bit smaller than the 32″ by 32″ bed. The whole point is to make clamping on the CNC grab and go. I put a fence on the new spoil board that is I’d say 98% squared to the machine. There is probably a small bit of error but it is good enough for me. The fence ensures that I have a consistent starting point, as there is a recess for my XYZ zeroing probe.
If the spoil board is ever damaged, all I need to do is chalk up a 2 foot by 2 foot piece of MDF and I can run a few tool paths, level the surfaces and I’m ready to go. Next on the docket is making cam clamps and it would be wise to make a few clamps that clamp the workpieces down in the z axis as well. The cam clamps will be designed to hold the work tight against the fence, so clamping will be fast and easy. I’ll need a set of z axis clamps for the heavier, larger toolpaths that I run into hardwood.
While the CNC is doing its thing, I’ve been carving a little wand. It sort of looks like Voldemorts from Harry Potter, but I’m putting my own little touches on it. It feels fantastic to be carving again, and it is very satisfying to see the shape of something small come together. I can sit and be around if something happens on the CNC I’ll be a few steps away from the red emergency button, and I feel like I’m getting more done this way.
I’ve still got to test the touch probe fits in the recess that I cut for it. I also need to ensure that the XYZ probing works for my machine. So far I’ve been able to probe for Z with no issues, but it would be fantastic if I could do all 3 and be super accurate. My next moves, after making a few simple cam clamps, will be to make a small lidded box, so I can quickly figure out the right tolerance for a snug fitting lidded box on the CNC. It’ll kill a few birds with one stone. I’ll get to test the new spoil board clamping system, the XYZ probe, and figure out the lid tolerance for the humidor project I’m trying to complete as well.
