Greetings. I have a suggestion regarding an enhanced table base coordinate system.

I built a hydraulic steel frame for my bot, and I use a laser optics bench as the working table. I can raise the table such that it touches the bot frame, and/or can be lowered to the floor.

Careful as I was to machine and level the frame, I still want that last 5%.

I would like to suggest a virtual leveler. Give me a keystroke combo that prompts me to touch the table at all four corners of a projects working area. This area could be the entire table or just a square foot. I'll have my keyboard with me, and use the arrow keys. I'll put a 1/1000 brass foil shim on the table. When I cant move it, thats the x,y and z limit for that corner. Repeat for the remaining three.

Presto! I have leveled the table and set the working limits.

If this message is inappropriate I apologize.

If this can already be done with combinations of VL, VA, ZT and the like, I'll figure it out by cracky!
