extrusion question
Quick question guys. I have done the extruder calibration in the sense that when i tell it to extrude 100mm of filament it does, measured this a few times now and get results in the 98-101mm range which i think is fine and within margin of error of measurement.
But, my question is, should i increase extrusion multipler anyways because when looking at a bottom or top layer of any print i make under a high amount of light you can see very small gaps in the layer and see through to the next layer. The lines of filament are not 100% covering each layer and melting into each other. Im talking tiny little almost need a microscope to see it gaps here nothing major, just wondering if increasing extrusion would make more solid top/bottom layers.
Ive seen some bottom layers that look like glass, and so far am not able to achieve that.
Re: extrusion question
Just try it and see the results. You can also try to increase the overlap.
I always check my prints by my eye and adjust accordingly. Every plastic roll is different and sometimes requires small settings changes if you want to achieve something special.

Re: extrusion question
Thats probably what im going to do just play around with it.
Another thing i was thinking just occured to me, as this seems to have only appeared lately, can nozzle wear cause this? how long do nozzle usually last, ive printed 1kg of PLA and 4 KG's of PETG on the stock nozzle so far.
Re: extrusion question
Logically, I would think nozzle wear would lead to over-extrusion--not under. Now a clog might cause under-extrusion. When the filament comes out of the nozzle, does it come out straight down, or at an angle (or "kinked")?
If none of those materials were filled with anything, and of decent quality (no/few impurities), a nozzle should last quite a while--certainly longer than 5 KG. worth of filament.

The PETG drips pretty bad when first heated, almost always goes strait down, only maybe 5-10% of the time does it curl up. All was just plain filament not filled. This is my first 3dprinter so not sure about filament quality, but i did mic it and the size was very consistent throughout the spool. And it is made by filaments.ca which from local printers i have talked to is one of the better Canadian manufacturers.
Im going to do a few test prints when i get home at 1.05 and 1.1 extrusion multiplier and see what happens.

Regular PLA/PETG without any additives doesn't really wear out the nozzle. I'm using mine on MK2 already for two ears without any noticeable degradation.

Good to know, because if you google nozzle wear you will see everything from it never wears out to change it every few spools. so for newbies like me its hard to find correct info.
Thanks!

Think about the source and their motivations--what are they selling (or trying to)?
Shills are all over the internet. 😉

Re: extrusion question
Have you calibrated the extrusion multiplier? Matt, on mattshub.com, explains how to do it. That and calibrating linear advance (also on mattshub) made a huge difference in my prints.

Thanks, i just loaded a new spool last night so ill check that out when i get home, i have a 36 hour print ill start tomorrow night and ill try that calibration first and see what happens.
