Anycubic Mega S Machine settings for Cura

[russ_puskarcik 0]

I just unboxed and assembled my new Anycubic Mega S 3D printer, and found Cura as the interface software. The first thing it asked me was to select a printer. However mine was not one of the choices. The following are the settings that I was able to glean from the manual... obviously incomplete. Can someone help me correctly complete this?

Machine settings:

Printer
    Printer Settings
    X (Width)    [210 mm]
    Y (Depth)    [210 mm]
    Z (Height)    [205 mm]

These settings are used when you select "One at a Time".  They tell Cura how close together you can put parts on the build plate.  They describe the "gray" area around each model.  These dimensions are measured from the centerline of the nozzle.  When you look at your print head from the front you can see the edge of the fan shroud on the left.  That would be your "X min" and the X max would be the dimension from the nozzle to the edge of the fan shroud on the right.  The Y min is towards the front of the machine and the Y max is towards the back.  The gantry height is the dimension from the build surface to the bottom of the X beam that the print head travels on.  I have entered my Ender measurements here.  Notice that the X max and Y max are pretty large.  I have a 50mm blower for cooling and it's mounted on the right and curls around the back.

Printhead Settings
    X min    [-26]
    Y min    [-32]
    X max    [32]
    Y max    [34]

    Gantry height    [25]

 

Copy this to your start gcode.  It will print purge lines on the right side of the print area.  The heating commands will allow the bed and hot end to heat together.  A line that starts with a semi-colon is a comment and is ignored by the printer.  Words between curly brackets like {machine_depth} are keywords and Cura replaces them with the actual value when the gcode is created.

And copy this and paste it into your end gcode.  After a print the head will lift and the table will come forward.

I have the ANYCUBIC MEGA S also, which I just purchased. I was struggling with the same issue, as the i3 and Zero are listed on the dropdown on Cura's installation menu, but not the "S." After doing a bunch of fiddling around and research, I learned that the "i3" option will work flawlessly. The settings for the i3 and S are identical. This may save some people a great deal of time and headache, knowing this.

 

Also, know that there is a "Cura" file on the SD card that shipped with your MEGA S, that was supplied by ANYCUBIC. The manufacturer recommends Cura as a slicing software. Just another tip.

Ultimaker just released a new updated version of Cura, v 10.0, which now has the settings for ANYCUBIC MEGA S and Pro in it. So easy!
