I attempted to print a companion cube (specifically this one). It turned out decently considering it was my 2nd print after some initial calibration. The issue is that the faces of the cube that are perpendicular to the X axis look great (image 1), but the 2 faces perpendicular to the Y axis are significantly less detailed (image 2). Another issue is the sort of open lattice pattern on the top of the cube (image 3). Any suggestions from someone more experienced than me would be appreciated! https://reprap.org/forum/read.php?262,174297,174297#msg-174297 Sun, 10 May 2026 19:20:53 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,174297,175278#msg-175278 https://reprap.org/forum/read.php?262,174297,175278#msg-175278 rrr7 Printing Sun, 06 Jan 2013 19:30:08 -0500 https://reprap.org/forum/read.php?262,174297,174361#msg-174361 https://reprap.org/forum/read.php?262,174297,174361#msg-174361
Yes you do need the nozzle diameter set correctly, but there is a setting for default extrusion width under print settings/advanced. Set that to the same value as your nozzle diameter as well, you will get much better infill results overall.

Of course you will also need to recalibrate the extrusion multiplier to correct for your nozzle settings.]]> Dirty Steve Printing Tue, 01 Jan 2013 21:18:44 -0500 https://reprap.org/forum/read.php?262,174297,174357#msg-174357 https://reprap.org/forum/read.php?262,174297,174357#msg-174357
I'm using the stock Prusa Z couplers right now, planning on printing a few of nophead's couplers ASAP. And no, the ends of the threaded rods are not restrained. Can you recommend a thing for restraining them?

Looks like I screwed up along the way and set my nozzle diameter in slic3r to 0.5mm instead of 0.3mm. I'll try fixing that and see if I get a more solid fill that way.]]> devonv Printing Tue, 01 Jan 2013 20:58:34 -0500 https://reprap.org/forum/read.php?262,174297,174356#msg-174356 https://reprap.org/forum/read.php?262,174297,174356#msg-174356
What kind of couplers are you using on your threaded rods? Do you have the ends of threaded rods opposite the motors and couplers restrained?

What software are you using to slice with? If you are using Slic3r, set your extrusion width the same as your nozzle diameter to get a better solid fill.]]> Dirty Steve Printing Tue, 01 Jan 2013 20:36:29 -0500 https://reprap.org/forum/read.php?262,174297,174298#msg-174298 https://reprap.org/forum/read.php?262,174297,174298#msg-174298

I also made sure my belts were tight and pulley set screws were tight as well.]]> devonv Printing Tue, 01 Jan 2013 15:58:57 -0500 https://reprap.org/forum/read.php?262,174297,174297#msg-174297 https://reprap.org/forum/read.php?262,174297,174297#msg-174297 specifically this one).
