Left V5 version. Right V6 version.
The hot end clamp is completely redesigned, but the baseplate and fan duct are the same. So if you upgrade from the V5, you only have to print the “cooler base” and “cooler door”
This hot-end carriage makes the bowden tube E3D hot-end V6 ( http://e3d-online.com/ ) compatible with the Felix 3D printer (1.5 and up).
Although I’ve made great prints with the original Felix hot-end, I’ve had some problems with it. The main problem I’ve had is jamming of the filament between the PEEK and the upper aluminium part. Even though the parts where firmly fit. I couldn’t use more than 0,75mm retraction which resulted in oozing over the printed part.
Pro’s for the e3D Bowden tube hot end and carriage:
- - Way lighter X carriage because of the removal of the extruder stepper motor
- All metal design, no more PEEK
- Better cooling
- Can reach Higher temperature. (don’t know why, but I can reach 270 degrees easily. The old one couldn’t reach 240 stable).
- Way faster on temperature
- More nozzle hole diameters available
- No clogging and jaming anymore!
- Cheaper
Con’s:
- - You can't use flexible rubber-like filament trough a Bowden tube
I'ts specifically design for the V6 version, The v5 or if a newer version comes up with a new layout cool-ribs, it will not fit. The cool ribs are printed inside the PLA clamp.
It does not use the supplied 30mm fan. Instead it uses the original 40mm Felix fan. More cooling less noise. I use it on 12V. But I think 5V works fine also.
It’s a two part design. The extruder carriage and the Bowden feeder.
This is the filament tension releasable feeder. Discussion over here:
The extruder carriage is made in a way that the nozzle-end is on the exact same location as the original hot-end.
I’ve made it also very easy to remove the complete hot-end. Just loosen two bolds and turn the door open.
I’ve made a new design for the extruded filament cooler, it’s more circular around the nozzle tip. So the part isn’t cooled from just one side.
Here is a video of the (V5) extruder in progress:

You have to edit the thermistor settings in the firmware:
open up the firmware in Arduino. Select the Configuration.h tab
Change:
Code: Select all
#define TEMP_SENSOR_0 8
Code: Select all
#define TEMP_SENSOR_0 1
Code: Select all
#define HEATER_0_MAXTEMP 275
Special thanks to Guillaume from Felix printers to supply the rail-base.
