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…

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.…

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…

Changing the temp from 200/60 in any degree triggers thermal runaway

I am new to 3D printing and having a strange issue I don't understand and would love some help with. I have an Ender 3 Pro and when I use the settings 200 °C & 60 °C it prints fine. However, I want to change the bed to 55 °C as the bottom layers are…

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…

How to print at low temperatures (filament melting at about 70 °C)?

I'm using Cura to slice prints from a biodegradable polyester called PCL (Polycaprolactone). I need to print @ ~70 °C but extruder does not run until nozzle reaches 175 °C. Which setting to change so extruder will turn on when nozzle temperature has…

Thermal Runaway E1 Error, Extruder text jumps randomly

Ender 3 Pro, everything is stock except that I swapped the magnetic sheet for a glass bed. As the tin says, I'll get this error around a half hour into a print: THERMAL RUNAWAY: E1 PRINTER HALTED Please Reset I recorded it in the act, and here's…

Acceptable temperature variation in heated bed

Ever since my original Creality CR-10S Pro heated bed quit and was replaced, I have had trouble with bed adhesion and printed first layer material warping using PLA and auto bed leveling. I am getting bed temperature variation between 71 °C (160 °F)…

How do I determine the glass transition of filament from its sales listing information?

I need to print some items that will go in my car, which sits in direct sun a good portion of the day and almost certainly exceeds 50 °C inside during the summer months (I've had PLA prints sag quite visibly under their own weight and sliding parts…

Irregular adhesion on Creality glass bed

I have an Ender 5 pro and upgraded from the magnetic bed to the glass version. I print with Prusament PLA on 65 °C bed temp and 220 °C extruder temp. I measured that the glass surface has ~58 °C in the center and ~56 °C on the corners. That should…

Direct vs Bowden Extrusion when printing in temperature fluctuating environment

I have a Bowden extrusion printer in my garage. (Printing PLA is smelly and is nothing I want to be exposed to for an extended period of time!) I enclosed the printer within a plastic sheet housing to reduce the energy consumption of keeping the hot…

Drop in temperature after couple layers

I'm printing basically a large flat square pane. This goes fine for 3 layers, after which the temperature suddenly drops by about ten degrees. After a while, my printer goes into thermal runaway protection. I restarted my print, and as soon as the…

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…
