So my prints suffer from over-extrusion but the flow rate fields in cura doesn’t seem to be working. I’ve made countless attempts trying settings ranging from 100% all the way down to 60% but nothing actually changes when I print. I thought I was going crazy until I saved the gcode before and after changing various flow settings and confirmed the gcode command values remained unchanged. It acts like cura simply ignores the filament related setting fields (flow %, diameter, and e-steps). Other settings work fine. Interestingly I’ve also noticed the print estimate stats (minutes, meters, and cost) also don’t change; filament diameter, for example, should certainly affect the filament length estimate! It shows it recalculating but then updates the estimates with exactly the same values - I assume this is the same issue.
I’ve tried resetting to a default profile. I’ve tried restarting cura in between setting changes. I’ve tried the newer cura for windows (v21.04 vs v21.03). I’ve tried numerous models. Nothing seems to matter.
Help! What am I missing? Since these three fields have clearly worked for others on this forum I don’t understand why it would be different for me unless I’m literally the only one here using the lulzbot version of cura.
Update: If I manually edit the gcode to reduce the extrusion values in every line to 1/3 the size the models print flawlessly. I assume this confirms this is a software issue (bug?). This highly manual workaround is super-miserable, however, and a terrible solution.
