How to tell if PLA temp is too hot/cold

I was having an issue with flat sheets raising up during initial layers. I had my bed at 80 °C and kept raising it thinking it was an issue with cold. After reducing the temperature to 50 °C the sheets sit flat now but sometimes sections come loose.…

What temperature should I bake PLA prints at to increase strength?

I recall seeing that it's possible to "bake" or "anneal" or even "remelt" PLA prints to strengthen them. As I understand it, the main effect is improving layer adhesion, which is the main source of weakness in tension in the original Z-axis…

BLTouch error causing bed and nozzle temp setpoints to change to zero

I replaced my CR-10 motherboard with no problems and ran fine for a few weeks, then decided to add a BLTouch. BLTouch was enabled from the config.h during compile. I had heating issues at first but eventually figured out I had the thermistors plugs…

Horizontal lines on feature/geometry/density change

I've had an Ender 5 Plus for a few weeks now. It's printing great and I've got my tuning pretty good at the moment. I've noticed some horizontal inconsistencies matching feature/geometry changes. It seems to be associated with maybe layer time(?) I…

Ender 3 hot end heater "stuck on"

Forgive this long-winded post, but I thought it would be helpful to include the back story leading up to a very scary situation on my Ender 3. I was printing a job and everything started out fine just like it normally does. I'm not sure if it is…

Calculating suitable pressure for compressed-air-based cooling

I've heard a bit about folks using air compressors with tubing to the toolhead and outlet openings there as part cooling. One example is the Berd Air, but from the information I can gather, it works with rather low pressures where the expansion of…

Does running a PID Autotune with an increased cycle count result in more accurate PID values?

I'm using the mriscoc firmware for Creality Ender 3 V2. The firmware has the option to run more PID Autotune cycles. The default is 5 cycles. Does running a PID Autotune with an increased cycle count result in more accurate PID values? For example…

Why is MPC better than PID for 3D printers, and (why) is it more useful for 'high-power heaters'?

The YouTube video 'PID vs MPC' from Mark Misin Engineering Ltd perfectly demonstrates that Model Predictive Temperature Control (MPC) is more powerful than Proportional-Integral-Derivative (PID). Marlin implemented MPC as described in Marlin's MPC…

Nozzle temp always reads 236 °C, even when it's room temp (Ender3 V2 Neo)

My first 3D printer, an Ender 3 V2 Neo. The original issue I was working to address was a clogged nozzle. The heat-block was caked in melted filament. At this point, I just chalked it up to a gap forming between the Bowden tube and the nozzle. I…

What are the consequences of printing PLA at too high a temperature?

When printing with basic budget PLA, what are the consequences of having it slightly over temperature. For example 5-10 deg above the recommended temperature for the brand, or significantly over temperature such as 50 deg? How will this be seen on…

Print failure due to heater inconsistency

After encountering an issue where the original heater cartridge (~40 W) for my generic MK6 hotend was unable to reach/maintain stable temperature at ~260 °C (for PETG) I replaced it with a higher wattage heater (60 W). The new heater heats up faster…

Ender 3 v2 temp fluctuations every 10 minutes or so

I have an Ender 3 v2 that will fluctuate the hotend temperature every 10 minutes or so and eventually causing thermal runaway. I have tried the PID auto-tune a few times and it seems to solve it for a couple of days. Any idea what’s going on? Today…
