So this weekend was supposed to be my first time cutting with the cnc.
Started out being most careful and precise drilling rails to secure to my waste-board and prepping and drilling a second layer waste board on strips.
Then sat down and did a program layout to drill holes to accommodate the flange insert nuts I got.
Well did a dry run no bit in router with a strip of my waste-board clamped up and watched the movement.
Here I was planning on using a 1/4 inch cutter and the hole only needed to be .328 so really very little movement.
But in the dry run it seemed to go way to big.
Well I paused just there to watch the Brady bunch win again and after had convinced myself it was all good.
So put a cutter in the machine set zero and hit run.
Oh boy bad things were said and I nearly had my pants full as the router ran into my one clamp.
It had not done that in the dry run but then again that was without a cutter so duh Rob #1
So scrambled with aluminum flying everywhere and it just powered through pushing clamp aside and continued to the first hole.
Well watched the first hole and sure enough it was way too big.
Essentially what is supposed to be about an 8mm hole is 16mm
In picture above you can see the hole and my clamping setup for the hole drilling.
Well went to look at the program again
Then it hit me between the eyes. “RADIUS”
No wonder it’s double so DUH #2 Rob.
Well as Linda said this is how you learn.
So now I had a wake up call. Also have to look at how I clamp or rather make sure the router misses the clamps. Lol
