I drilled my first DRO driven circle pattern today. A Chinese DRO with fun instructions. totally useless instructions, but fun to read in a public setting none the less. So like every other function on this thing, I winged it. Target is 127 holes on a 7.75" circle.
Select holes-on-circle button
It asks for DIA. I want 7.75", so input 7.75
It asks for Org and suggests 0. I accept 0
It asks for End and suggests 360. I accept 360
It asks Num, and I input 127.
I then dry run checking every ten points or so. First uh-oh is the first co-ord is 7.75, 0. Run through it to hole 64 and it's a -7.75, xxx. Ohhh kay. It asked for Dia, but really wanted Radius. So I exit and re-enter everything using 3.875 as the "Dia". The dry run looks okay. I didn't look close enough.
The second rut-roh Shaggy can as I passed 90 degrees. The Y coord didn't change betwen the two holes either side of 90. I should stopped and thought it through. But I drilled on to the end..... figured out my massive blunder, then redrilled the entire thing at a radius of 4.05".
Anyone see my mistake? No it's not finished, but the mistake is not in the picture. I had to reclamp it to bore the center out and drill a small pattern or two that I'll need.
