Posted · Pause the printer at a manually setting height of the build plate

Hi all, 

 

I want to pause the printer at a manually setting height of the build plate. 

When I use M0/M1, it indeed pauses but it goes down to the lowest height. Here is my code.

M18 S5
M0
G1 Z100
G0 Z0.6
;LAYER:2

 

Is there anyway to pause the printer at a manual setting height of the build plate?

Thank you!

    If you do a quick test with Pause At Height at Layer:2 you will see that the code generates "relative" moves as well as absolute moves and inserts the proper resume height as well as the resume X and Y locations.

     

    Note that if the file is created with Z-Hops or Adaptive Layers then you must use "By Layer" because the variable Z location of Z-Hops confuses the plugin when it's set to "By Height".

     

    In your code snippet:

    M18 S5 ;This will cause the steppers to disable in 5 seconds.

    M0 ;pause.  You have 5 seconds to do what you are going to do.

    G1 Z100 ;drop the build plate to an absolute Z=100

    G0 Z0.6 ;Move the build plate to absolute Z=0.6

     

    If you take longer than 5 seconds before re-starting the print then the steppers disable and lose their position.  That makes the Z100 and Z0.6 really iffy as to where the print head is actually going to end up.  The X and Y position are lost also and the remaining print would be catastrophically off.
