/diy/ - Do It Yourself

Heya 3dpg. Wanhao i3 plus, hooked up to pc via usb onto S3D, please refer to attached screenies of settings. 60C bed temp, 200C extrusion temp.

The majority of my prints are done without supports and my models reflect this preference. So far my prints have been good until rather recently. 0.4mm nozzle has had roughly 6mo of on and off work, not under or over extruding and my prints are to size. Printing fresh PLA. I have two issues:

1) Some parts of some prints suddenly underextrude and cause bad layer adhesion, bad fill and thus bad structural integrity. The nozzle is still good and my extruder gear is fine - no grinding or loosening at all. This problem is persists through prints and is triggered by support structures. Without supports, very rarely does it shit over a layer. The problem seems to persist among prints requiring support structure.

My initial thoughts were along the lines of having the retraction bug out and not push out the retracted distance - I have turned off retraction and it did not solve the problem. I have turned temp up to 230 with no appreciable result. Any of you had this problem or know of its causes?


2) I have a starting script of squeezing out filament to prime the nozzle at the beginning of the print. Every now and then, instead of extruder rotating such that it extrudes, it retracts filament during this time.

While not a huge issue, it's just a bit annoying. Any of you had this problem or know of its causes?


On another update, jellyfish cast soonish. I have just received a probe thermometer and will attempt to record temperatures ideal for pouring.
