Just got the first test prints off my new TAZ.

Just got the first test prints off my new TAZ. The outer walls are looking great but the infill is turning out poorly. Supposed to be 0.4 honeycomb infill. Does anyone knwo what might be wrong?

Using Marlin, repetierHost, and slic3r.

Looks like it’s over extruding, did you confirm 100mm of extrusion is 100mm of filament and that all axis are moving wht there told

I have only iterated once, but its pretty darn close. It cant be more than 2% off. on any one axis. Could that be the problem?

I also notice that slic3r is only creating gcode for the infill on 2 out of every 3 layers. No idea why or if this is a problem.

Check to see if you’ve got infill every n layers set to 1. Also, try doing a 100% solid infill and see if you have the same problem.

Infill is set to every 1 layers. When I set infill to 1.0 it still only fills every 2 layers in the gcode preview, although I have not tried printing with that setting

Try re installing your host software. If you upgraded from say repetier host verX to a new version the Slic3r profiles dont always get along with newer version.

Uninstall host software and slicer then reinstall you will have to setup slicer again.

@Jeremy_G_WeisTek_Eng I did not upgrade from a previous version. This is the first slic3r profile I have tried creating. Do you still suggest reinstalling?

Better yet - try another slicer:

@Evan_Gillespie

It’s a possibility that something may have gotten messed up. I know for a while my slicer profiles wouldn’t let me change certain settings. So a re install fixed it.

Also you can try going back a version or two to see if that helps.

One more thing, under advanced in printer settings in slicer, set your extruder width to your nozzle diameter eg .35 that was another issue I was having. Another one more thing make sure your heated bed is truly flat. Mines got an awesome bow in it. Fixed it by re installing the glass plate, well half of it anyway.

@Jeremy_G_WeisTek_Eng Thanks. Ill try reinstalling repetier host tonight when I get home.

I’m pretty sure that my bed isn’t perfectly flat because these were just my first two test prints. I assumed that it was no big deal because these prints are so small. 2cm across.

I recommend trying cura for the slicer too. Also either check the online Goode viewer or repetierhost or cura for a good Goode preview. At least you could narrow the problem to the slicer if it looks strange on the preview, it’ll look strange printing.

It looks like you’re using PLA. Which extrusion temperature are you using? Make sure the extrusion temp is not still set to the default 200C in Slic3r. Start at 185 for PLA. Also, your bed may be set too high for PLA. Try 50C for starters.

I’ll try lowering my bed temperature and experimenting with different slicers tomorrow. Thanks for the ideas.

@John_Ridley Good point. I will try setting my layer height to the nozzle diameter and slowing the infill down.

Layer height should definitely be <=nozzle diameter. If you have it above that value that’s very likely your problem. Good catch +John Ridley.

I had the layer height set to 0.2mm and am using am 0.35mm nozzle. Going to try increasing the layer height to 0.35 and slowing the infill speed down when I get home.

@John_Ridley So I’m down one possible solution. Slowing the infill down still seems good.

What speed are you trying to print at? I find 50mm/s is a good starting point. As for layer height I usually do .35 for a .4 nozzle and .3 for a .35 nozzle. I don’t like how long things take to print at .2. Also starting with rectilinear instead of the more interesting infills is also good. Is there still printer night? I’d come down if you were bringing it. Or if you need some eyes sometime for diagnosing.
