Trouble using conditionals in Slic3r 1.38.6-prusa3d
I'm trying to add a custom end print step that will move the z to 50 if it is below 50 (to make it easier to remove the steel sheet). Based on the two sources listed below it seems like one of the following should work.
{if layer_z < 50}G1 Z50{endif}
{if [layer_z] < 50}G1 Z50{endif}
Both of them choke with an error on the layer_z placeholder however. What am I missing?
https://github.com/alexrj/Slic3r/wiki/Conditional-Gcode-Syntax-Spec indicates I need the braces around layer_z while this GitHub issue indicates it is ok to not have the braces: https://github.com/prusa3d/Slic3r/issues/683
Here is the error I am getting:
!!!!! Failed to process the custom G-code template end_gcode
Parsing error at line 7.
{if [layer_z] < 50.0}G1 Z50
^
!!!!! End of an error report for the custom G-code template end_gcode
Thanks.

Have you tried the latest beta version of Slic3r?

I tried this morning with no luck. I actually get different errors if I use the brackets vs. not.
With the brackets it has an error parsing the line:
!!!!! Failed to process the custom G-code template end_gcode
Parsing error at line 7.
{if [layer_z] < 50}G1 Z50
^
!!!!! End of an error report for the custom G-code template end_gcode
Without it tells me layer_z is not a variable name:
!!!!! Failed to process the custom G-code template end_gcode
Parsing error at line 7: Not a variable name
{if layer_z < 50}G1 Z50
^
!!!!! End of an error report for the custom G-code template end_gcode

After some more experimentation, it seems that layer_z is only valid in the layer change fields for custom g-code, which doesn't help in my case.
Re: Trouble using conditionals in Slic3r 1.38.6-prusa3d
Looking at the code on github, it only inserts calculated layer placeholders (layer_z, layer_num, current_retraction) for processing of the before and after layer custom gcode. Maybe if I get some time I'll take a stab at keeping track of the last layer height printed and maybe the max layer height printed and make those available in the end print gcode processing. Need to get my MK3 calibrated and rebuilt with the new parts first. 😆

Ah, thank you! I had to create a custom printer with this Z change code for the temp tower so it could process the conditionals for layer_z
