M208 and Deltas

[fcwilt]

Hi,

I have read the the M208 command does not apply to deltas BUT I see a M208 S1 Z0 in my config file.

Does that make any sense?

Thanks.

@fcwilt have a look here:

That line is limiting your movement in Z to Z = 0 (which is generally a good idea, you don't want to be able to command your printed to bury the head in the bed!

Hi,

Thanks much.

I will have to read the referenced material more closely as a quick scan didn't reveal if that command is essential for normal operation or not.

The M208 minimum Z value does apply to deltas. The M208 XY min/max and Z max values don't.

Thank you.

That is just what I needed to know.

Perhaps a note should be added to the G-codes documentation explaining this.

That's great - perhaps other confused folks like me will find it helpful.
