Hi all, I'm hoping you'll be able to shed some light onto an issue I've been having - regardless of temperature setting, my V6 heating slows dramatically after reaching 180°, and cannot go higher than about 235°. I haven't tried to print with it yet - I'm just trying to heat it up for the initial hot-tightening. The printer is running off a smoothieboard, with a 24v power supply and a 24v heater cartridge. I've built several other printers with 12v V6's and never encountered an issue like this, so I'm hoping some of the experts around here will be able to weigh in. I've attached a temperature graph from repetier and an image of my setup - what am I doing wrong? I've confirmed with a multimeter that the cartridge is receiving a constant 24 volts through the entire heatup, so I don't believe that is the issue.
