I've read Ken Rychlik's thread on this matter. I am convinced that zeroing from the bed is the correct way. I am wondering how everyone is doing this.
Have you created an "off-table" z-zero plate like Ken's or are you just zeroing directly off the spoil board? Zeroing off the spoil board seems like the easiest solution, but what if you have rezero while a sheet is on the table.? I guess you can't do that or does this even come up.
I believe having a off table z-zero makes the most sense however this file modification really worries me. I heard that you can set-up a file to surface the table and a seperate program will modify the z-zero plate by that difference. I have not done anything like this, programming that is..
Also, I have just added a couple of air drills to my alpha. Which means these have to be zeroed as well. What, if any, special considerations do I need to observe with these?
As usual many thanks for the help!
