Good For High Temperature Printing
8 August 2019
This is my view of the E3D hotend after using it for a few days.
I originally ordered the V6 because my stock hotend simply couldn't handle PETG at 240.
The stock hotend can reach that temperature, but the prints constantly jammed. In fact, I used almost all of a reel of red PETG trying to tune the old hotend.
In terms of fitting, it all went together easily.
Before doing anything at all, read all of the online guides, and make sure you have all the parts you need printed before you take your old hotend apart.
I struggled to find an adapter that included both the BLTouch and the V6 mount.
Thingiverse eventually provided the right files.
In terms of assembly, the mount I picked needed both M2 heat inserts and M3 inserts.
This was a bit of a pain, and I discovered to my cost that I needed to attach the OEM part cooling fan BEFORE mounting on the printer.
The part cooling fan is almost impossible to mount when the hotend is already fitted to the printer.
You also need to flash your Marlin firmware.
My version seemed to have different names for the parameters to the instructions, but there was a specific E3Dv6 switch in my config.
In terms of performance, I have so far tested the V6 on PLA (200 deg C) and PETG (240 deg C).
Ran a couple of test prints at 200 for PLA:
Quality was almost identical to the old hotend, maybe slightly less good at some bridging than the original.
For PETG, ran this at 240.
The problem with the old hotend was in order to get the PETG to stick to my print bed, I had to run it at a higher temperature.
But the high temperature led to excessive stringing, blobs, and constant jams.
I think this was because the old heat break did not do its job and the filament was melting inside the heatsink.
(This was supported by looking at some of the plastic plugs I pulled from the old hotend when clearing the jams).
Well, so far, I am very pleased with PETG results at 240:
* Much less stringing and blobs. I am not sure why this is, but could be due to better heat control.
* No jamming at all - this is what I really care about.
In addition, the new head looks slightly smaller/lighter than the old head, and it is easier to see the print underneath it.
The stock hotend also gave me a lot of trouble with slightly cheaper filaments. Many of them require a higher print temperature to stick to the bed, but this leads to jams as the plastic melts too high in the heatsink.
I am very optimistic that the V6 will stop this issue and give me more flexibility on the print temperatures for all materials.
In summary, buy this if you want to print at higher temperatures, or if your printer jams often with melted plastic jams.
It's probably not worth it if you just print in PLA and have never had a heat jam on your printer.
