Are there printers that don't have thermal runaway protection?

This question asks about the reasoning behind thermal runaway protection and how to turn it on. However, how do I know if my printer does not have protection in the first place? Either because it is shut off by default or, if such printers exist, is…

Extruder retracts filament while moving from default start line to actual object location

I am new to 3D printing and recently got a second hand RF1000 and am busy calibrating it. For this I want to print a basic calibration cube. I noticed the print doesn't always start with enough filament in the nozzle. To make sure the starting point…

Upgrading to higher torque extruder motor creality ender3

So according to E3D customer service, the V6 is designed to have higher back pressure than the MK8. This leads to underextrusion with PLA and all kinds of problems unless you increase the temp by 30 - 50 °C so it will heat the filament faster and…

Sparkmaker SLA resin not curing

My model layers are printing much as I expect but the parts when removed from the plate are very soft and flexible and fail to harden any further in sunlight or UV lamplight. A tall or slender part will bend and distort under its own weight while…

Can a single line of Gcode have variable extrusion rate?

Fairly long winded, but hopefully makes sense; I understand that G-code is executed line-by-line, and in the main printing phase each instruction is effectively go to location XY (assuming staying within the layer) at a set speed with a set…

Is PETG filament food safe?

I've been trying to find a 3D printer filament which would not release any chemicals if in contact with heated water for a substantial amount of time. So far, I've easily ruled out both PLA and ABS, as they're not considered food safe from what I…

ANet A8 running Marlin v1.1.9 Auto Bedlevel with ROKO SN04-N

I'm trying to get the ROKO (SN04-N) sensor to work with my Anet A8. First of all, while trying to screw it to the extruder, I tightened it too much and sort of broke the acrylic plate... sort of. I had to use a very thin steel plate with two holes…
