There are mounts available from the BigTreeTech website and also dozens available on Thingiverse.
#HEMERA RETRACTION MANUAL#
If you have a “regular” 3D printer with manual bed leveling, a BLTouch, capacitive sensor, and the cabling running all the way to the motherboard then mounting this extruder is a matter of printing a mount and doing the cabling. You can use it for mounting it to your printer, adding part cooling and mount an Adafruit Neopixe. On each of the four sides, there are two M3 screw holes for bolts. The BIQU H2 compared to a standard AA battery Mounting itīIQU has made this extruder very easy to mount.

The BIQU BX comes in a nice small box, but it will turn out this extruder itself isn’t actually that big.
#HEMERA RETRACTION FULL#
I wrote an unboxing article earlier about it for full details, so you may want to check that out as well.
The BIQU H2 (hydrogen) is a direct competitor to the E3D Hemera direct drive extruder. I’ve had the “World’s lighest direct extruder” for a month now and let’s see if this is a true direct drive without compromises. This extruder the same extruder as mounted on their BIQU BX 3D printer. You can also post here your Factory file I can have a look on it, let me know… (also your retraction distance is impprtant we recomment 0.7-1.BigTreeTech sent me their BIQU H2 direct drive extruder for review. Now the solution (I guess the second reason ): try decrease retraction speed to 15-20mm/s OR decrease print speed to 40mm/s or set layer height to 0.2mm instead default 0.25mm OR try different PLA brand This deficiency becomes visible when you start with our Thin Wall printing… you can have a look here in retraction topic When is our Extruder/HotEnd/Nozzle in good condition this should not have happened (also filament have some role). Or increased resistence in HotEnd/Nozzle (delayed delivery of the filament) so when starting printing just after retraction we dont have enough amount of filament. Hello David, yes this looks like start point under-extrusion, there is two reason: a filament leak when nozzle is traveling (in detail look you can see it) increasing retraction distance or lowering temperature should solve it. My extrusion values are 0.40 nozzle, 1.03x multiplier which gives me EXACT weights for wings. I’m at a loss, I don’t know what else to try at this point. 240c is already 30c above the maximum advised temperature for this filament. I’ve also increased the bonding on thin sections like that by increasing the temperature, but much beyond 240c and it will be pretty terrible at bridging. I’ve also mitigated it somewhat by increasing my travel speed to pretty much maximum for my machine (140mm/s). It does not under-extrude at any other time, only after a long delay (like a long travel move). I’ve increased the prime amount after retraction – I’m currently at 0.14mm – but if I increase it much beyond that, I get bulges in other areas that go through the wing.
I’ve gone through 45 revisions of my settings to try and get rid of this issue. The problem is that the very start of a new outer shell on a thin wall segement after a relatively long travel move – say from the leading edge spar back to the trailing edge start, the first several MM of the line are under extracted. I’m using mostly your stock values for Simplif圓D – with my own retraction and speed settings that have been tested through what is now 45 tests of one of the wing profiles for the Stearman. I’m having what I believe is a pretty unique issue.
