I got a Mini for Christmas and have done a few prints on it but I’m seeing a few consistent issues which I would appreciate some help with.
I’m a newbie so not really done any printing before. I’m using colorfabb ngen filament and standard ngen profile in Cura - standard prints.
I have tried a calibration test piece on high quality settings and it’s pretty much off all over the place but the main problem is the initial layers.
I have done some searching and reading of posts on the forum and picked up some tips but I’d like to make sure I don’t damage my new printer, hence I’d like specific advice just in case I mess something up!
Cura settings for ngen:
pritt stick over bed as advised
After bed levelling, when it starts to print it doesn’t extrude any material to start, or intermittent, which is just about okay as by the time it’s done the outline it’s sorted itself out but I’ve been doing several pieces so it’s got time.
The initial layers seem to be squashed? a little so they end up wider than they should be. I printed some tetris style puzzle pieces (fit together into a cube) and all the bottoms were wider than the rest on the first two layers. I had to sand them down to fit into the box.
I also printed the makerbot robot http://www.thingiverse.com/thing:331035/#files as something a bit more fun and although the arms are wonderfully articulated, the legs are not (these were printed first) and I had to cut them loose. The lower joints don’t work at all.
I also printed a calibration test file http://www.whoote.com/viewtopic.php?f=3&t=3 and that is also way off. Every dimension is off by at least 0.5mm though it seems to get more accurate over larger dimensions.
It’s supposed to be 50 x 30 x 2mm. Mine is 50.63 x 30.58 x 1.42mm. The holes are supposed to be 3mm, 4mm, 5mm. Mine are 2.5mm, 3.52mm, 4.29mm
I printed a couple of filament clips and although the hole is just about 3mm at the top, there’s no way it’s 3mm at the bottom. You can see it’s way off.
- How do I print a wider outline so I can get the extruding working properly?
- How do I calibrate so that the printer does better first layers?
I’ve attached photos of some of the problems.
Any help appreciated.
