Is anyone doing auto location of a center point on their plasma cutter? We have a home made plasma cutter that uses a Baldor ESB cntroller and a touch screen to let the user pick a part. I already have a simple digital joystick control for this machine. It occurs to me that I could let the operator pick a center point in a piece and then a size and we could cut circles and squares on any sized part. A laser pointer mounted on the side of the z axis could be used to pick the center point, then account for the offset in the controller.
I put a Dynatorch laser on my table, love it and use it every day.
How does the laser hold up to the heat of the flame cutter?
Will it fit a standard machine torch for oxy/fuel?
When I first started cutting, I left it on and noticed the laser getting dimmer. The laser on my HK 40 does the same thing, after a couple hundred rounds the glass is all fouled up. It makes it hard to hit the stuffed animals (plushy toys if you want to be politically correct). Plasma dust is similar. a q-tip soaked in nitro solvent cleaned it up right away.
