Input Shaping dosent work in PrusaSlicer

[MrBrain295]

Putting M593 F{(layer_num < 2 ? 0 : 15 + 45.0 * (layer_num - 2) / 297)} ; Hz Input Shaping Test (from here) as the layer change GCode in PrusaSlicer 2.5.1 gives this error: Post-processing script M593 F{(layer < 2 ? 0 : 15 + 45.0 (layer - 2) / 297)} on file /tmp/.22125.gcode.pp failed. Error code: 2 Output: /bin/bash: -c: line 1: syntax error near unexpected token (' /bin/bash: -c: line 1:M593 F{(layer < 2 ? 0 : 15 + 45.0 (layer - 2) / 297)} '/tmp/.22125.gcode.pp''

Where exactly did you put the given code? Your error would indicate you put it in the post processing script instead of after layer change gcode.

edit: just to be sure I tested this in Prusa Slicer 2.6a6 and it worked as described.

Yeah I noticed that but I put it in the layer change gcode. It also showed up in the post processing scripts section although I didn’t put it there. I thought it was a part of prusaslicer but it works now after removing it. Thanks.
