Using Cura Lulzbot Edition 3.6.18
I added a post-processing steps to do a Color change. There is a script actually named Color Change where you can enter the layer. I have used it a few times an noticed it always paused for color change a little earlier than i wanted. I defeated this by simply using a higher layer number, but this last time it paused at Layer 14, and not Layer 17 which i requested. I opened the G-Code, and sure enough, I found the plugin had inserted the color change command at Layer 14, despite me plugging in Layer 17.
(apparently this is a known bug in the Cura world, that may have been fixed but i think Lulzbot is using an old version of Cura)
all the plugin does, is insert the following line of Gcode- so its pretty easy to do that manually to your G-code at the correct layer:
M600 E300.00 L30.00 ; Generated by ColorChange plugin
Also note that G-Code layer’s are zero based, and Cura is 1 based. So if your desired layer in Cura is 17, you need to put this snip at Layer 16: here is a snippet of my code (you can paste your M600 command after the MESH tag:
;LAYER:16
;MESH:
M600 E300.00 L30.00 ; Generated by ColorChange plugin
