OK New Wrinkle...I send a Job from F-Engrave to Tap File....If I set the Depth at  -.0001 or -.0125....The Depth does not change.... I am perplexed...This Just started happening today....

Billy

Nevermind ughhhhh.....Piece was bowed.....

Hi Billy,
I make circuit boards which require extremely fine depth control even with PCB blanks that have modest bow/warps. I use:

and would be of value to anyone doing engraving.

Thanks Craig...! ! ! !

Update.... A Few Things.....Turns out that we have a 15 degree angle on Flex Bits...Not 30 degree standarrd....so getting bits re-tooled...
Our Dahlgren spindle speed goes from 3000 to 23000....and we run brass at about  11000...Reading up more ion the Mach3 software and tweeks...Once I get the Bits Back..... I can give a better update.....

Billy

Hi Billy,
yeah 15 degree bits are VERY tender.

Craig

For Plastic (Soft)...Its all Good ...When we took over the other company....The Person who ran the Dahlgren was like me trying to run the CNC at first ..... We went by the Specs that he initially had as far as the bits.....What he had was incorrect...
I found that out by doing a Back Check with Antares... under the other companies name....They said that ACE got 15 degree not 30.... When we would send the bits in to be re-sharpened...We always thought they were 30....But now we know  that as well
