I cut out a wood base for the sled. I ended up using 3/4 melamine chip board because I had a leftover shelf piece that was nearly the exact right size. It is probably too tall by 50% and probably adds more weight than is needed. 1/2 would probably have been better. I still have the model, so I can recut new pieces relatively easily in the future.
Now I need an acrylic window to really cut down on the sawdust.
I think I am also going to move to a metal bar for my motor spacing. It looks like my motors moved about 5 mm closer together then when I last checked them. This could be caused by seasonal changes or because my green wood wasn’t fully dry. 5, is a sizable change. I would like to avoid doing the holey calibration as much as possible. It seems like every time I do it, I get one of the measurements wrong and spend 30 minutes tracking it down.
One downside to the 60 tooth sprocket on the z-axis, the motor has a bit of slop. My best guess is that with the 3x sprocket setup with an 8mm lead screw that this results in about .2mm of slop.
Also, does anyone else giggle a bit when using their maslow? It never ceases to amaze me that this silly looking contraption works as well as it does.
