I just bought a refurbished Taz 3. This is my first 3D printer, but I have a couple CNC machines, so I’m pretty familiar with most of the concepts, and have been lurking on this subreddit for awhile.
I was doing some test prints and I just can’t get anything all that great out of it. It’s a Taz 3, but has a PEI bed, upgraded 600W power supply, and a few little upgrades here and there. I leveled the bed as best as I could. I actually used some 123 blocks to get it leveled, and that helped a bit. I then set the Z position and got it to where it would lay down the first layer without curling up, or mashing it down. I made a 1cm cube in solidworks and exported it to an STL file and tried printing that. Here’s an album with 3 tests:
I’m using HIPS (esun). Bed temp is 85C, extruder temp is 230. 100mm/sec is the speed (on the third I tried slowing it down and it didn’t do a lot). I measured the filament and it’s around 2.9mm on average, so I’m using that. Any thoughts? I’ve seen some GREAT stuff come from a Taz, but so far mine’s pretty far from that I’m using the custom version of Cura, using the Taz 4 profile (there’s no profile for 3).
