gcode syntiax for a command M117 LAYER [layer_num] Z [layer_z] plus 1
Hi all,
i'm again with this problem, i use the command M117 LAYER [layer_num] Z [layer_z] in tha "after layer change GCODE" and it work but the layer is wrong, for example, when printing layer 2, on a 0.3 print, the line is LAYER 1 Z 0.6
There is a way to add a 1 to the layer number ? i tried
M117 LAYER [layer_num+1] Z [layer_z] but tell error on gcode creating
M117 LAYER ([layer_num]+1) Z [layer_z] as above and other test.
There is some way to have correct layer number ?
thanks

If you use the correct brackets you wont get errors when creating gcode
M117 LAYER {layer_num+1} < note the type of brackets used.
displays as the correct numbered layer on my printer. I generated a simple 9 layer print to test it and on the first layer it displayed "LAYER 1" and on the last layer it was showing "LAYER 9"

You may want to move your gcode to "before layer change". I think these two fields are named confusingly. From what I can tell, the "after layer change" is actually "after printing the current layer but before changing to the next layer", and conversely the "before layer change" seems to be "after changing to the next layer but before printing on the new layer".
Or, my interpretation is wrong... 😉 I guess some experimentation should be done with a simple object using identifiable tags in both the before and after layer change gcode and then looking at the resulting code to see what the result is. I'm just too lazy to do this at the moment. 🙃

i'll try. because i have still some problem. Now (m117+1 in "before" section) the layer is correct, start with 1 and same level as preview.
But sometimes i have a strange issue, i have different layer height value between preview and display printed.
for example:
M117 LAYER 1 Z 0.375
M117 LAYER 2 Z 0.675
M117 LAYER 3 Z 0.975
but in preview i see:
why ?

@sembazuru
i tried. no change value are the same (before was simple. after was+1), between there is only a single row
