Re: Calibrated extrusion multiplier, yet still have gaps

My feeling is that the behavior in a two-layer print is going to be a bit different than a calibration cube. Funky things happen at the interaction of the bed and the first layers and in your search for a setting that works everywhere may lead to lots of frustration. At some point, you might just h...

Re: Calibrated extrusion multiplier, yet still have gaps

Make sure your nozzle diameter is set to 0.35 in your slicer, and try another nozzle if you can. This sounds like a clog. Alternately, check that your extruder is perfectly vertical relative to the bed. Sometimes a good whack will spin it in the holder (especially with the V3b) and you'll end up wi...

Re: Calibrated extrusion multiplier, yet still have gaps

Thank you so much for the insight guys. The thing is, even if I squish the first layer flat and put tons of layers on top of it, the top layer finish still has gaps. I've always calibrated the first layer height by how it looks going down but double checking with the calibration cube, the height is ...

Calibrated extrusion multiplier, yet still have gaps

Since I switched to the V4 and a new roll of the same filament I have been using (matchbox 1.75 black PLA), I haven't been able to have smooth top surface finishes without boosting the extrusion multiplier. Calibration cubes lead me to a multiplier of .93 yet I can see light through a two layer flat...

*v4 is an EXCELLENT design.
Totally agree. Here's the file for the filament drive cover if you want it.

Re: V4 Heat Creep - Melted Plastic Above Hot End

How about heat creeping through the mount and into the bearing carraige? Does that mount feel like it gets real warm or hot over a long period? It hasn't been bad yet, however, I've only printed PLA and have been using the bed fan with no shroud so some of that air is aiding in cooling the aluminum...

Re: V4 Heat Creep - Melted Plastic Above Hot End

In my opinion it's not needed. I've been running one of my printers for the last 3 months without the extruder fan and haven't had any issues. The only thing is you just can't just unplug it as the extruder and case fan are both 12 volts and run in series. (they may have changed this on newer print...

Re: V4 Heat Creep - Melted Plastic Above Hot End

I wonder why the extruder fan is even necessary? Would happily ditch it and it's noise if it doesn't make a difference.
