Turning off heatbed for the last few layers. Good idea or not?

My heatbed won't let go off the prints until it considerably cools down. The cooling process takes decent amount of time. I was considering putting the M140 S0 (sets heatbed temp to 0) somewhere near the end of the printing process, so that when the…

How to straighten PTFE tubes?

PTFE tubes are typically delivered coiled up. And because they are quite stiff, they always want to spring back to their original curvy shape, making them harder to route properly. Is there a way to straighten them out?

MakerBot Replicator 1 Voltage Regulator Fix

My Replicator (you know, the one made of balsa wood) has blown a voltage regulator on its MightyBoard for the second time. The first time, MakerBot graciously replaced it. However, they replaced with the same model board with no apparent fix for the…

Levelling heads for dual extruder

I upgraded to a dual Mk9 extruder, and quickly discovered how critical it is to get the ends of both nozzles exactly level with each other -- that is, equally distant from the build plate at all times. Otherwise the lower one will crash against the…

What causes these round corners

Nozzle diameter = .4 Extrusion multiplier = 1 Extrusion Width = .45 <-- I feel like this could be reduced to fix it? Layer Height = .3 I'm using Simplify3D.

Are self intersecting meshes dirty from a 3D printing perspective?

I have never much cared about self intersecting meshes when slicing with Cura. Geometry like the one below are often practical. I for instance add lots of rivets that self intersect with the base geometry: Now I have switched printer, and am using…

First layer overlap on one side

When printing the first layer, the infill overlaps on just one side of my print. Thereupon there's a rough, and a lot higher, surface on the first few millimeters after the wall. Printer: Arduino Materia 101 Filament: Rec Pla Temp: 210 degrees I…

What resolution (pixels/mm) should I use in SVG for CNC?

I am planning a mechanical 40% keyboard build and are coincidentally on the home stretch of a homemade CNC project. The only thing the CNC needs to do for the keyboard project is to drill 7*48 holes. So what I need to do now is layout those holes in…

Using CAT6 cables for 3D printer motor / sensors / fans

I'm considering using CAT6 cables to connect my printer's extruder assembly to the control board. They seem like an elegant solution, but I've read conflicting opinions online on whether or not this would be feasible. I would like to know if CAT6…

One corner never sticks

I am new to 3D printing. I thought that the black surface of my print bed was supposed to keep things stuck without additional tape, spray, etc. However, every time I print something, this same corner, and only this corner, detaches. Any advice on…

Z-axis steppers and bed alignment problems

I've actually solved this, but I think its still a useful question which I don't think is easy to answer with existing questions. As soon as I'd built my ANET-A8 (Prusa i3 DIY kit), I found I was having problems with the extruder crashing into the…

Print fails at perpendicular boundaries

I recently changed the printhead on my DeltaMaker from stock to an E3D Lite6, and am struggling to get back to my original quality, reliability, and repeatability. I thought I had gotten the recipe pretty close to dialed in and tried a bigger print…
