I picked up a v6 after my Ubis finally killed itself. I'm trying to get everything up and running without any issues. I'm having a problem with a clicking coming from the extruder hotend (not 100% sure where its coming from) It doesnt seem to be happening on retraction but its intermittent through the bottom layers as well as the infill. Running e3d v6 1.75mm direct drive on a Printrbot simple metal MakerGeeks clear PLA @ 218degrees .8mm retraction @ 25mm/s 40mm/s print speed Hopefully someone might have a hint to whats causing the noise, Please let me know if any more information is needed.
