Separate names with a comma.
There's a ~3mm gap between the heatsink and heat block, right?
25w will get you to ~280C, so that's not the issue.
Soon, like fewer days than you have fingers...
Unless you've been in a terrible accident, in which case my apologies.
A couple months from when I said a couple months (October 16th) is still reasonable.
Sounds like you're running a 24v hotend on 12v, you'll want to check both the fan and heater voltages.
In the process of developing those, a new and better approach was discovered. The approach described in that video won't be used, as the new...
Do you mean 183C or 283C? You said 183C but I suspect you meant 283C.
The HEATER_0_MAXTEMP is a hard limit resulting in a system fault, you...
MK3 comes with 40w.
As a counterpoint, in the event of a controller failure, a 40w heater can get hot enough to melt aluminum.
Also the heat required to actually...
Prusa MK3 uses a standard E3D thermistor cartridge, though it has a different cable.
MK3 is 24v 40w, Volcano is 12v or 24v, 30w. Either are fine,...
Yes, a proper size drill bit would qualify as a "proper tool". You might be surprised to find how many people use/assemble 3D printers these days...
The 45 degree angle is slightly better, but an unnecessary step for the home-gamer.
Easy to do on a production line though, but benefits are...
77kohm sounds about right for a thermistor at that temperature. 77ohm does not.
This probably has more to do with the thermal conductivity of the polymer than the actual temperature. Our bodies are better heat flow indicators...
Too many factors to do a one size fits all table. Many types of PETG, many additives, many different extruder motor torques.
A reasonable limit...
Does your spare PT100 sensor have red leads?
What is its resistance at room temperature?
Looks like a bent lead screw, I'm not sure why shipping damage is something to get mad at E3D for.
What exactly are you referring to? Could you mark up a diagram?
And there is no "throat" on an E3D hotend. There is a heatbreak, though.
Sounds like incorrect firmware settings.
