Relation between layer height and bond strength

I've seen many references to a FDM print being weakest in the Z axis, due to poor bonding between layers compared to the extruded walls. Thinking about optimising this for a specific material (excluding temperature and geometry), is there an…

Should I vary the first layer height

Up till now, I've tended to scale my first layer according to the print quality, so a 0.12 mm first layer for a 0.08 mm print, and 0.28 mm for a 0.2 mm print. After changing to a PLA which isn't sticking well, I'm wondering if the first layer is…

How to install a .hex firmware?

Creality does offer its firmware on creality3d.cn as .hex files. These are pretty good as backups as one can't alter and destroy them by accident. But... How do you install them?! This is about installing firmware directly and without another…

Identify temperature sensor

Am wondering if anybody knows what type of sensor this is (from a build plate). Perhaps a thermocoupler? The colouring of the wires seems to suggest it is not directional? Would like to know details so that I can make use of it in my own projects.

Will a glass bed warp as it is heated?

I purchased a glass bed to use with my still-in-transit Ender 3. Since the bed came in before the printer, I pulled it out and used a flat edge ruler to see how flat the glass surface is. It appears the glass is slightly "dished" in the center from…

Heatbed control with Pronterface

I'm having trouble getting my MendelMax 2's heatbed not to heat up when I want to print without it. I don't get how multiple sources of control relate to each other (same with extrusion temperatures, actually): Slic3r (1.2.9) has settings under…
