Thanks for the confirmation that this bizarre controller logic is correct. Is this the case with many modern controllers as well? IMHO, it is a bad idea. Zneg should be Zneg regardless of what you are doing. You are either below or above Z0, that’s my 2 cents.

Thanks for the input, especially telling me what the controller is looking for with the three z values. I know how the depth or first z is controlled or what determines its pp output. The other two z values I am having a harder time with.

I must have got lucky on the first one “4970”. I cannot get the drill op “5160” to output the second and third value correctly. I have been over the settings in MC more times than I care to mention.
Anyone, know what specific options in MC drill/peck parameters control or should control second and third z values. Or have you run across an issue of when “X” is chosen then “X2” needs to be set to “X3” etc.

Thanks,
