How to utilize/calibrate print fans for PLA?

Everybody's combination of fan hardware and print settings is different. Unless someone else has the exact same printer and slicer profiles as you, there's no way to really say anything like "use X% ...

Efficient and easy way to thermally insulate the heat block of the hotend?

The "quick and dirty" approach is to just slap a bunch of Kapton tape on there. The more the better! (Until you need to dismantle for maintenance, anyway.) I find pre-cut ceramic tape + kapton tape "...

Efficient and easy way to thermally insulate the heat block of the hotend?

I ask myself why people hassle with kapton tape when it is so easy to use teflon sealing tape to isulate the hotend. This tape is slightly foamed to allow better sealing when used for sealing "tube ...

Clogging due to heat creep: buy new cooler or new hotend?

To fight heat creep, you must understand why this is happening. Heat creeps up the hotend assembly (into the cold end) as a result of incorrect settings or hardware setup causing the filament to ...

Power consumption of filament extrusion

This is very simply stated, in fact the specific heat is a function of temperature and state of the material (liquid or solid). Also you need to consider which type of specific heat you use, e.g. the ...

Creality CR-10S Pro 3D printer heated bed turns off after first few layers: normal?

If you start a print there is an "Adjust" button, that will take you to a screen where there is an option "Economic". It that is left on it will turn off the bed heater during the print.

60 watt heater into 40 watt heatblock

I'd expect the heater sticking out as pictured to cause problems -- the exposed part of the heater will tend to overheat (it's not conducting heat away into the heat block) and isn't protected by the ...

Failed filament dryer deformed my filament. Is it salvageable?

It all depends on how much the filament is deformed. If there are not many conjoined places, and you can easily unroll the spool, it should be fine. You should also check filament diameter, because if ...

Heated Bed vs Heated enclosure for large scale printer

I tend to agree with Davo, that you might want both. But I'd probably try the enclosure first. My printer is about 1200 by 400. I looked at options, and found some difficult trade-offs: First, the ...

My extruder does not reach the set temperature

It could be as Carl Witthoft said, that the thermistor is broken. But it looks like the PID is not calibrated correctly. It probably can reach higher T's but stops, because the P portion is not high ...

Creality CR-10S Pro 3D printer heated bed turns off after first few layers: normal?

No, this is not common behavior, and yes this can cause your prints to warp or detach from the build plate. The question is whether you instructed this (by accident) or not (e.g. it can be a result ...

No. Your formula is quite off, and it starts with the nomenclature: Watt Watt is the unit of energy transfer which equals power. The commonly used term "wattage" does not exist in science. ...
