That is a twisted vase of my own design, I will get it and some others posted up on thingiverse soon.

Just never heard of Dorkbotpdx. may have to check it out big_smile

And after I posted that it seemed to be working, back to not working.  Resistor still shows resistance.  But it just wont heat up now.  Repeteir shows that it is trying to send the command just get nothing from the hot end. I checked for voltage at the resistor and nothing.

Turns out I have a broken wire or solder joint at the 4pin ATX header I use for my hotend and thermistor connection at the side of my extruder.  Work on it more tomarrow.

(They do 3d printing lots too, and drones etc... )

And once home used a multimeter and the resistor is getting 6.4ohms like it should. reconnected and now able to heat again.  trying a print right now.

Have to get a look at it when I get home. I think the resistor stopped resisting..... Time to get a heater cartridge big_smile
