I'm having a lot of pla jamming issues with my new v6 lite extruder. Reading most of the posts on this forum there is no mention of what the actual temperature of the fins should be near the heat block, in the docs on the e3d site it just states cool to the touch! So I measured mine between the Botton two fins on the centre tube. I'm getting 61 deg. C with the extruder set to 220 deg. C. Please could some of you on here make the same measurements. I'm suspecting my fan may not be performing correctly I purchased a couple of Fans while I'm waiting for the guys at e3d to send me a replacement. by the way fantastic support from e3d I have dealt deal with 100's of companies and they are very good .. results from hot end set at 220 Deg C and measured temp between bottom 2 fins Fan type...................................... fin Temp Deg C.......................................Jamming issue sirocco yx2501 30 x 30 x 6............ 58 ...................................................... randomly Multicomp MC36310 ......................51......................................................... 2 jams in 4 hours of printing E3d fan....................................... ....41................................................ None yet Also the first fan I had from e3d was only drawing 60mA the new one is 105mA m so a good check to see if it is running correctly
