Filament change

I know in Cura you can stop a print at a certain height but is their anyway to do it at a certain layer?

 

There is a plugin for that but it doesn't work with marlin afaik.

I believe someone was able to modify it to work though.

 

I don't know how Cura does its gcode, but if you open the gcode from Simplify3D, there are a lot of comments like the following:

Code:

; layer 3, Z = 0.9

If you toss an M25 after the layer you want it to pause at, you'll be able to tell it to pause at a specific layer. I also prefer to move the print head off of the print just to make sure it doesn't mess anything up, you can do that by changing the following sample code:

Code:

G1 X84.940 Y135.275 E28.9775
G1 X84.940 Y135.841 E29.0029
G1 X85.159 Y136.060 E29.0168
G92 E0
G1 E-1.0000 F1800
; layer 3, Z = 0.9
; inner perimeter
G1 X84.600 Y136.400 F4800
G1 Z0.900 F1000
G1 E0.0000 F1800
G92 E0

to something like this:

Code:

G1 X84.940 Y135.275 E28.9775
G1 X84.940 Y135.841 E29.0029
G1 X85.159 Y136.060 E29.0168
G92 E0
G1 E-1.0000 F1800
; layer 3, Z = 0.9
; inner perimeter
G1 X5
M25
G1 X85.159
G1 X84.600 Y136.400 F4800
G1 Z0.900 F1000
G1 E0.0000 F1800
G92 E0
