Hex VI formally know as XCR3D v6
« on: April 04, 2018, 07:10:51 AM »
               


   Ali E just too tempting to pass over this one at £13,  It seems like a convergence of three designs which draws me to testing this Xcr3d v6, terrible naming from what I read on the WWW its branding name from sways, so it gets a REBEL name HEX VI " roles of the tongue and a Killer Angel said so..  8)".

     The design  takes on the appearance of the hexagon hotend, appearance only dimension are larger  which makes it one of the longer hotend on the market. comparable to the E3D v4. The heatbreak similar to the chimera heatbreak, and nozzle fitting and V grove comparable to E3D V6.

       The arrival ( 9 days from china to the UK) came in a bubble envelope. I opt for option D in the store which was hotend, 50W heater and thermistor. and a free gift " 3 needles like thing for unjamming!! ominous sign of tears to come. fun aside  looks handy to have around  sure beats  a strip of wire.  What is missing from the kit is a allen key and given this design centers around the use of grub screws,  but am rebel with a tool box.  ;)

             

     First appearance cant complain at all, does look like a well made piece few small dent in the fins but nothing major ugly. 



coldend:
 The inlaid fitting a nice touch keeps the overall length down, though at times felt like a fight to remove the bowden tube, not something I want to do a lot.

         

"Great texture. Hotend surface is with oxidation scrub, and the black paint texture makes it more upscale."
 just no idea what that meant  ???  I have to ask is it really necessary to coat,  what is essence a low temperature hotend max temp of  260C due to the liner " imagine there a small liner in the nozzle.
 BUT rather see the high quality  bare polished aluminum.
 
 overall its looks well machined and cleaned up. with a  raised lip where the heatbreak slips into, should make it easy to see if the break slips while printing.

heat break:
    This is why I got this hotend, I've wondered for a while now "after seeing it done with the e3d chimera. Use of grub screws to hold the heatbreak in place and the possibility of a quick change of nozzle sizes, like that alot. If the grub screw hold up over time I can see this becoming a standard feature, designers may have to rethink just how much they shave of the cold end in the pursuit of smaller, lighter!.
          The heater block smaller (16*16*12mm) than the V6, reminds me of original hexagon design just without the cornering. hard to do a direct comparison of the hexagon or  AO as I cant find a single spec drawing.

           

      The heater block came already assembled and  I utterly forgot about preheating to 260C and tightening further. but appears the heat gods were on my side as it wasn't needed in the end.

         Installation was straight forward the V grove mount of the Jhead makes it a drop in for all existing V6 users, I kept  the heater and thermistor already installed  so no need to alter firmware.
the kit came with 50W cartridge and  HT-NTC100K both appears a better quality than your typical V6 clone. 

           

  burn off: If I had to do this again I take it outside  whack up the temp to 250C and leave it for half a day " yeap a nail in some wood and hang it ". The odour reminded me of an electrical melt down of the heatbed terminals after about 12 hrs  and between 200-210C the heater block transitioned from a ninja to a turd settling close to dull copper in appearance I hope they make thermal socks.
   
           

   about five hrs into printing you see the residue "dye" build up round the thread of the heatbreak first thought am leaking but that turned out to be a false alarm. on the plus side they offer  three other colours  so you can colour co ordinate those nozzle sizes for as little as £3 "like that price £4 you can have a steel nozzle.

     Overall am pleasantly pleased, first 12 hrs gone smoothly filament change been smooth and flawless, happily printing along with pla at 200 with a retraction 5.8 varies layer height between .18 -.3
