Enable Auto-Sleep parks print head on part

Post by Dbounce »

I recently purchased the Artemis and have been getting to know it. Playing with settings to understand where the limits are. My last job was a 9 hour print so I enabled Auto-Sleep so that the machine would not continue to run after the job was ended. Much to my surprise, when I returned to the machine the following morning, the job was completed, however the printhead was parked on the completed part, ruining the piece.

It seems to me that Auto-Sleep should re-home the printhead, not park it on the completed part. Is there a way to modify this behavior?

"sleep" turns off the motors. When the motors are turned off in a well tuned delta, the weight of the effector platform can cause it to slide to the bottom of the machine because the motors are no longer locked.

Did you add a "sleep.g" file to your configuration? As far as I know, the Duet3D depends on that file. If you remove the M84 command that will prevent the motors from being turned off.

Note that the amount of power that the Artemis (or any 3D printer) uses when cold and idle is pretty trivial.

The end g-code in Cura typically homes the machine after the job is done, so you really don't need to use the auto-sleep function if that's all you need it to do.

Thanks, I’m new to this so I’m still learning. Btw... it’s very satisfying seeing my concept materialize before my eyes. Loving it.

No worries. Everyone is new at one point or another. :)

Good luck!

Some delta printer owners use a retractor to apply enough upwards force on the effector or on the Bowden tube to prevent the effector dropping when the motors are turned off.
