2 years ago You have if statements in your g-code. Cura does not support these. If you remove them everything will work as normal again.
The offending line is
M221 S{if layer_height<0.075}100{else}95{endif}
Application Version
5.0
Platform
Windows 10
Printer
Prusa i3 Mk3/Mk3s
Reproduction steps
I altered the starting-gcode from the i3 Mk3/Mk3s preset to work with my DIY i3-like machine. Slice any file with cura 5.0 and the temperatures will not be set as defined, but the start G-Code is taken literally. This results in the printer starting to move without any heaters turned on... :/ In cura 4.13, the same start G-code in "machine settings" produces the desired results. Similarly, when I use the unaltered start G-code from the preset for the Prusa i3 Mk3/Mk3s everything works as inteded. However, since I am not running PrusaFW, but vanilla Marlin instead, I cannot use the preset.
Actual results
The start G-Code contains: [...] M104 S{material_print_temperature_layer_0} ; set extruder temp M140 S{material_bed_temperature_layer_0} ; set bed temp M190 S{material_bed_temperature_layer_0} ; wait for bed temp M109 S{material_print_temperature_layer_0} ; wait for extruder temp [...]
Expected results
Instead I want the start G-Code to contain (e.g.) [...] M104 S210; set extruder temp M140 S60; set bed temp M190 S60; wait for bed temp M109 S210; wait for extruder temp [...]
