@Pops2 You might want to also consider building a simple “L” bracket which will guarantee stock alignment to the travel of the gantry.
I built my simple “L” with a two pass process to ensure alignment without having to rely on measurements:
- Using the same hole design (c2d file) that I used to create my waste board (I have a “Myers” design), I copied the c2d and then stole only the bottom outside corner’s worth of holes to save a new design file.
- I then drew a perpendicular “L” to the inside of the holes
- For Pass 1, I clamped a rectangle of wood to my CNC and pocketed the holes only.
- For Pass 2, I screwed the rectangle to my spoil board lugs through the holes I just created, and ran the toolpath to cut out the “L”. This guarantees that the “L” is perfectly aligned with the holes on the board - without having to measure anything.
Because of the two passes, the CNC will cut the “L” relative to the holes in your spoil board, so you can place it anywhere on the spoilboard and be sure that any stock that’s aligned within the “L” is going to be perfectly aligned to your gantry path without having to rely on your eye. It works really well.
I also made a few out of different thickness boards, so I can reduce interference in the inside corner.
