The details for this and all other G-codes are documented here. {REPLACE "\nM117 Layer 4, Z=" "\nG1 X10 Y5\nM0\nM117 Layer 4, Z="} We tend to spend a lot of time focusing on key parameters affecting the final print quality (layer height, infill, perimeters, etc. Add multiple lines and change the layers for multiple pauses. Here’s an example of using before layer change G-code for changing temperatures on a temperature tower. It will look something like the below: So, if supported, G4 S60 would do the same thing. M226: Gcode Initiated Pause Example: M226. Thingiverse is a universe of things. This matches the behaviour of M1 in the NIST RS274NGC G-code standard and M0 in Marlin firmware.

This script uses a special text string for describing a search pattern called regular expressions. {REPLACE "; layer 3, Z = " "\nG91\nG1 Z20 F5000\nG90\nM0\n; layer 3, Z = "} Of course, you will need to decide the layer number to pause at (more on this in a bit). Note also that the “\n” parts of the code simply creates a new line in the GCode. In Repetier host and printrun you can add commands in the gcode that only control the host software. Just open the G-Code in notepad and use ctrl-F to search for “ZX” where X is the height (in mm) you want it to stop at. G4 P60000 will wait for one minute. Then you can insert a G-Code pause, which will depend on your firmware. Topic starter hi, the title says it all: I want to put gcode into the sliced file, so that my printer (CR-6 SE) will pause after a certain layer in order to change filament. The P is in milliseconds. Some firmware also accept a S Parameter that has the seconds. This model consists of 10mm segments which are printed starting at 235C and decreasing by 5C at each 10mm layer.
