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…

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…

M3D Micro printer stops extruding but is not clogged

I have an M3D Micro 3D printer that printed fine for a couple of weeks and then was plagued with issues afterward. I've done the fixes from the forum to get proper heating and cooling of the nozzle (I've added aluminum foil around the nozzle to make…
