Z table drops

Post by Explorer71 » Thu May 26, 2016 3:54 pm

Apparently there is some sort of timeout for the z height. When I have adjusted the table to do a table level or adjust nozzles, after a certain time the table drops down to the ground position, usually before I'm done. Is there any way to disable this or change the timeout time?

Yep! There is, and I think it's:

M84 S0 ; disable idle timeout

But if that's not it, one of the guys will pop in.

Okay, if M84 S0 sets the timeout to 0 and disables it, does M84 S60 set it to 60 seconds/60 minutes ?

No earthly idea.....but probably. (I realize this is pretty low tech, but I use masking tape to tape the knob in place while I'm working, and i don't have to worry about the bed taking a ride before I'm ready. There are also several printed locks on Thingiverse if you prefer to do it that way.) :D

The timeout is mainly used when you pause a print, I'm not sure if it works the same for things like leveling. You can always try it....set it for a minute and see what happens when the minute is over. :D

Yes... Stright from the Wiki

For example, "M84 S10" will idle the stepper motors after 10 seconds of inactivity. "M84 S0" will disable idle timeout; steppers will remain powered up regardless of activity.
