Using stock seemecnc thermistor only because I couldn't get the thermistor that came with it to stay in the hole reliably. Also, the hole for the heating cartridge was not a very good fit. I had to drill it out so it would fit properly. Also be careful when tightening down the stainless steel parts, I twisted mine on accident. luckily i bought two.
The temperature readings were only about 3 degrees off from the stock hot end setup. I wanted to see how this thing would perform at higher temps so up'ed the maxtemp value to 300c and only got calibrated measured reading of 293c on my thermocouple temp probe. Even though rephost says 299c. The temperature chart seemed to fluctuate more starting at 260C and up. So i'm guessing i need to rerun the pid autotune. Maybe that will smooth it out and get my reading more accurate?? will do when the temps get back to room temp.
Included some photos of the new hot end mounted. At 293c this thing barely gets warm, unlike the stock setup which at 220, i could not comfortably touch the bowden adapter without getting burned. Although, I think I would prefer a higher cfm rated fan. Already on the hunt for one.
temperature probe is inserted all the down inside the tip of the ED3 Nozzle for calibration purposes. Also this turn out to be a little trouble seems as though my thermocouple is not rated for 300c. even though the package says otherwise. I managed to melt the insulation of the sensor somewhat. Hopefully there's not a lot of plastic stuck in there to affect my prints or extrusion. maybe the bits will come out hopefully after a couple of extrusion cycles.
Decided to wrap my hotend up this time with ceramic insulation and kapton tape to keep the radiate heat of the printed parts. and to help stablize temp when part cooling fans running.
random shot of it all mounted up.
