How much insulation do I really need?

I have been looking at cork sheet insulation for my 200 mm x 300 mm aluminium PCB heatbed, by I am not entirely sure how thick it should be. There seems to be a trade off between losing a few millimeters of print height, and providing adequate…

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…

Weird bumps cylindrical hole

Not quite sure what's happening here. I printed it as a single ball and had this effect. I thought it might be a cooling issue so I printed 4 at once but the issue still occurred. If I size the ball up, the problem reduces. Note that the hole is…

First (bottom) layer has gaps

First off - I'm rather new to this and I might be on the wrong track altogether... I'm printing PLA using a simple DIY XYZ printer with a direct-driven extruder, 0.3 mm nozzle, 0.2 mm layer heights, using Slic3r. I've tried to calibrate the bed as…

I am experiencing some severe under extrusion

I did calibrate the extruder to extrude exactly 50/100 mm and it is fine. I have replaced the old (prehistorical) extruder that was giving me the problem with a new one. The issue does not go away. It is severely under extruded. The nozzle is a 0.4…

Does the printing substrate have to be glass? If so, what size?

I am new to 3D printing. I have just put together my own 3D printer with some help. I was advised I shouldn't print directly onto the aluminium plate - I assume it's aluminium. The manufacturer did give me a piece of matrix board (i.e. no cooper at…

Connector Suggestion for Extruder and Heatbed

On my Reprap-like 3D printer, I routed all the wires to a spot near the base; for the motors, endstops, thermistors, etc, I plugged them all into a DB25 breakout board, and that's working great. For my Extruder (12v), and my heat bed (16v), I'm…
