    If this is the canister style thermistor, I really doubt you damaged it. It could have come in bad. Sanity check all your connections to it just the make sure.

    That is fine for the heater core connections.

    All connections seems to be tight and corrrect. Still zero reading. Must be a lemon

    Not familiar with the RAMPS you are using (I use the standard RAMPS 1.4 on all of mine). Is that the thermistor connection or the FAN 0? On mine the thermistor doesn't land on that type of connector :) It lands on T0 or T1 (depending on if it is the hotend or the bed)

    This is the Robo supplied RAMPS IIRC:

    That is the Print cooling fan, not the thermistor...looks like your extruder thermistor is in a similar spot (T0 -- middle of the board)

    Maybe you just landed some of them incorrectly?

    Yes thank you it was wired wrong. Now bed ave extruder warm up. Started test print and the extruder motor is erratic. Either i plug it in backwards on the ramps or I crimped a wire at the top. Signing off tonight thanks for your help. I'm focusing on that later

    Good luck.
    If you plug the connector the stepper in backwards it will run backwards.
    It could be that you need to either swap the stepper driver card for a new one or adjust the current output on it to be higher*.




    I am lazy and they are cheap so I usually just swap the stepper driver.

    Wanted to give a warning about the 40mm fan upgrade:

    I did a Titan extruder and V6 upgrade. I don't even have part cooling fans on the extruder carriage as I print in ABS only.

    After getting the new upgrades all setup and done, I started printing my normal parts, which are small and many of the same thing. I noticed that I was having bed adhesive issues. I hadn't changed anything with the bed, but always had the bed adhesion issues in the same spot. I cleaned the bed with some good chems to get it down to pure, bare glass. New glue stick (always has worked very well), new filament roll, perfectly dialed in for first layer height and other parameters, nothing. STILL warped off the bed in the same places.

    So I grabbed a spare bed (has a couple chips out of it from experimenting with PETG), cleaned it very well, put it on and the same thing: comes up off the bed at the same place.

    I grabbed the non-contact thermometer and the heating was even.

    So i coated the bed with Wolfbite, which I bought a while ago but never used. Worked EXCELLENTLY, except in that SAME TROUBLE AREA.

    Then I re-sliced my parts and orientated them different on the plate, avoiding the trouble area. Interestingly, the parts in the same area relative to the other parts being printed was warping right up again.

    Frustratingly, I started seeing it as a cooling issue. I upped the bed temp, put the cover back on (my office is warm, so it typically isn't needed in summer), no dice. Then I noticed that the 40mm fan I put on the V6 can't put all the air through the shroud, and some kicks back out the intake side. Yes, the fan is orientated properly, polarity properly. It puts out PLENTY of air through the heat sink, but the fan is capable of too much.

    I took that 40mm fan off and put on the stock 30mm fan the V6 came with. Issue solved.

    So the excess air being kicked back out the fan was acting like a parts cooler on my ABS parts in that particular zone relative to the bulk of parts being printed.

    This should be a non-issue with PLA, but for ABS, the 40mm fan doesn't work.

    It is generally accepted that you do not cool ABS prints with a parts fan, you can in most cases without any issue but that is not the norm. I understand why you were having issues. Also if you intend to cool parts that normally don't require cooling don't use the fan at 100%, that is why you have choices in your slicer. It doesn't always have to be 0% or 100%. An upgrade to two 40 mm fans or a 40 mm on the hotend heatsink are worthwhile upgrades, you just have to be careful how you use them.

    Not sure you understand. I don't have parts cooling fan(s) on my printer, never need them. I did run the wire for a parts fan in the wire chain, but it doesn't go to anything. A parts fan would just be excess weight to move for me. The 40mm fan upgrade for the v6 hot end was either just plain to big or the shroud needs some re design. Or the 40mm fan I bought is higher output than normal. Whatever it was, it was unable to push all the air it grabbed through the shroud/cold end, and was spitting it back out the "front" of the fan and cooling my abs parts. This phenomenon did not happen with the 30mm oem fam. Like I said, probably would not matter with pla, but abs would not tolerate the air flow io the parts.

    I'm very much aware of adjusting the slicer settings .
