Issues with Pause at height - anycubic mega s


Recommended Posts

Posted · Issues with Pause at height - anycubic mega s

Hello!

I have a anycubic mega s and i'm using cura 4.10.

I tried many times with pause at height, both with mm height and layer height , marlin or BQ and it doesn't restart.
After it stop, I don't get any resume button on the screen. 

 

Do you have any ideas about how to make it works?

    There should be a specific command that tells the printer to stop "right now" and for your printer I believe it should be M0.  If the command is ignored then there is a problem in the firmware, I suppose if it does pause but then the command won't continue it would also be a firmware problem.  I think you would need to get support from AnyCubic for this issue as I am sure Cura is adding the line to the gcode.  It's just that the printer isn't enabled for it.

     

    You don't need to print a whole file to check on what might work.  You could make up a short gcode file just to see if you can pause and resume.  If you start a text editor (like Windows Notepad) and enter this:

     

    G28

    G0 F3000 X100 Y100 Z10

    M0

    G0 X10 Y10

    G0 X100 Y100

    M25

    G0 X10 Y10

    G0 X100 Y100

     

    Then save it as "save as type" = "All Files" and then name the new file as a gcode file - you can print it.  

     

    M0 works on my Ender but M25 only works when I start a print using M24.  Using that example snippet above, my printer will pause at the M0 but blow right through the M25.

     

    If you have "Z-Hops" enabled then you can't use "by height" as the search criteria can be confused by Z-hops in the gcode.  Using "by layer" works well for me.

    In the Pause at Height dialog, the bottom setting box is for "gcode after pause".  If you put in "G4 S300" then the machine will dwell (a timed pause) for 5 minutes (300 seconds) and then restart by itself.  Just make the number of seconds something you are comfortable being able to swap colors in.  Practicing is good.  A drawback is that you have to be standing there staring at it because it will just go back to work at the end of the time period.  There is also no command to make the dwell shorter.  If you make the dwell 25 minutes (G4 S1500) and it only takes you 1 minute to change filament, you are going to wait the other 24 minutes for the printer to restart.  The maximum "disarm timeout" is 1800 seconds.  If your G4 command is more than that then the steppers will lose their position before the print resumes.  If you set the "gcode before pause" to M300 there will be a beep from the printer.
