Yes - I am aware that the M569 'S' parameters do not match the comment text.

Maybe it is your A3 axis that is configured as S1 that is the problem?

Thank you for your response.

Okay - "DUH!" - but, it is in reality rotational (nozzle) - and, this error has not always shown up. (Regret that I did not mention that before.)

For the most part, it has all but never shown up before (with A3 S1). It happened once before - and, the only thing I could do to get rid of it was revert machine.xml to an earlier version - which I was hoping not to have to do at this point, as I just finished making a lot of job and configuration changes. I was hoping someone might already have a clue about why changes to machine.xml might create this error out-of-the-blue.

[CodeDataTech]

What I meant by my "DUH!" remark was that - yes - it is painfully obvious (my fault - except that I ignored it because the nozzle stepper motor is in fact actually rotational).

The remark was not directed at anyone else - just an admission on my part...

[CodeDataTech]

In other words, if my 'A' axis is set up as 'rotational' - why would openpnp complain to the level of saying it was an error? And, why only in some very special unique circumstance that shows up out-of-the-blue...? (as opposed to all of the time since the beginning)

[bert shivaan]

I can't answer to the randomness of it - I do agree that would be painfully annoying. Maybe I&S will allow you to accept the setting and ignore the error, but when you upgraded it reverted that setting so now you need to accept anf ignore it again? (not saying I am correct or if I am how you would do that)

OpenPNP has always treated all axis as linear, even the rotational ones. To my knowledge this is still the case. 

I took no ill from the DUH statement - I assumed it was at yourself - LMAO

Well - needless to say - I can change it to 'linear' and see what happens.

There is no 'Accept' option in this case - only 'Dismiss'. I can 'Reopen' it and 'Dismiss' it all I want - but, that is it.

Thank you for your input - and, for jarring me out of my "tunnel vision" on this issue...  :-)

(I literally ignored/overlooked it because I was so sure that it could not possibly be the cause of the error - because it was actually rotational.)

But - more important - the issue seemed to "just show up" without any changes to the relevant commands/settings having been made to the config.g file in a while now.

In other words, the relevant commands/settings in the config.g file have not changed for a sufficient amount of time as would have made the error show up much earlier...

[CodeDataTech]

Defining 'A' as 'linear' in the config.g file and turning on the 'Switch Linear Rotational' option in the axis settings seems to be what was needed...

[bert shivaan]

Wonderful!! 

Thank you for reporting back the end result.
