Conditional code for layer height

tapirath

I'm trying to convert this PrusaSlicer code to a RRF macro. Is there a way to achieve it? where can I find the documentation for all the possible variables I can use?

; 0.2mm layer, 8 bands 5mm each, total height 40mm
{if layer_num== 1}M572 D0 S0.0
{elsif layer_num== 25}M572 D0 S0.05
{elsif layer_num== 50}M572 D0 S0.10
{elsif layer_num== 75}M572 D0 S0.15
{elsif layer_num== 100}M572 D0 S0.20
{elsif layer_num== 125}M572 D0 S0.25
{elsif layer_num== 150}M572 D0 S0.30
{elsif layer_num== 175}M572 D0 S0.35
{endif}

@tapirath something like this (not tested!):

if exists(job.layer)
  if job.layer = 1
    M572 D0 S0.0
  elif job.layer = 25
    M572 D0 S0.05

and so on. Object model job.layer will only be present and correct if the GCode includes recognised layer number comments.

Maybe take a look here: https://forum.duet3d.com/topic/26272/incremental-pressure-advance-m572-tuning-macros

Perfect thank you both

If you do write this macro in RRF, you'll still need to insert a custom bit of gcode in your slicer that is called on every layer change. And that custom gcode is an M98 P"<your macro name>". This will call the macro every time a layer is changed. After doing precisely this myself, I found that I preferred to do that work with slicer code.

I prefer the macro because
1- Cura doesn't have conditional gcode
2- I can use the macro with any Slicer without changing it
