There are many hot end designs out thee and one difference is the length of the melting zone.
The melting zone is that part of the hotend where the pushed in filament is heated up and therefore starts to melt. Is it better to have a short melting zone, or a long melting zone? What are advantages of each solution. And are there materials that benefit from a short/long melting one more than others?
Short melting zone melts material in small amount which is suitable for thin layers with small nozzles. In opposite long melting zone can heat big amount of filament which is needed for fast printing and thick layers.
Example of those hotends are E3Dv6 and E3D Volcano
E3D Volcano with much longer melt zone then v6

to crash into the bed. It sounded like something popped, and the printer restarted. It is now showing a MINTEMP error message, and both bed and hotend temperatures read 0°C. The only visible damage is that a thin layer came off the printbed - After testing with a multimeter, I realized that the metal under this layer is connected to power. As both the bed and hotend were heating, I believe I may have caused a short. Replacing the thermistor on the hotend with a spare did not solve the issue. I tested the thermistor on the printbed with a multimeter, and it seems to be working correctly
and pulled it out after heating. I have a long length of wire that is similar to the tiny cleaning wire that comes with the kit. Is it safe to heat up the nozzle and push the wire all the way through? I... and reconnecting it. It held a while as I tried wiggling it when heated but did not break the jam loose and broke off again... What should I do?
I've seen article about World's First 3D Printed Bike. What kind of printer is required to do that, briefly how long it takes and how much does it cost? Is this even achievable at home? Doesn't need to be that specific one.
. (I've added aluminum foil around the nozzle to make sure the hotend is fit snug against the nozzle and I've added an external fan, powered externally, to compensate for heat creep.) This works very well for short prints and it usually finishes successfully. When I do a longer print it always stops midway and usually at the same exact point. I tried printing at 200°C with black PLA... because if I stop the print and press extrude without letting it cool down, it extrudes fine. What is causing my printer to stop printing?
I have a long 8mm smooth steel rod of about 55cm long. This rods bend easily due to the length. If I replace them with 8mm solid carbon fiber rods, will the bending reduce? Will the bearings wear off the carbon fiber rod? I couldn't find too much information about this.
I'm considering buying this package, the Kossel, as my first 3D printer. It's not the cheapest model, but apparently a high resolution and stable, which is what I'm after. The question is, what...

I recently upgraded to a E3D full hotend and I started to have problems with slowly printed parts. After I print first object and start next one, then the first layer has serious issue. The first two test were extruded around 10mm/s, the right one around 15mm/s. The material is PLA (fillamentum.com) at temperature 210°C and nozzle diameter is 0.4mm.

I have a solidoodle 4 and have blown the power supply . Long and the short of it is I am trying to modify a Xbox 1 power supply to fulfill the need. I am measuring he voltage at the output and its 14.04 volt. Question is this, is the operational voltage range on a solidoodle able to operate on 14 volt ?
previous version of Marlin, 1.0.2-1, everything was working perfectly. I've transferred every parameter over from my older version to my newer one. There were some aspects of code that were written differently, but essentially everything works except the Z-Axis. Problem: The one issue that I seem to be having is with any kind of movement with the Z-Axis. When it moves, whether from the LCD..., it will accelerate normally for the same amount of time/distance/steps, go into this unholy mode for a period of time/distance/steps relative to what it was instructed, and then smoothly decelerates
