Topic: How to identify a temperature sensor on a solidoodle

Recently i found a 3D printer lying around in our company warehouse.
I got it and found that the main board was bad so i bought the Ramps 1.4 kit and installed it. The X,Y and Z axis motor run good manually. I have also set them up with their single side limit switches.


Problem 1: Now since this morning i have been trying to run the extruder motor and set a temperature on it. I am using the Marlin firmware. I didnt do much changes on the configuration program until i found that i have to set a temperature sensor in the program. But this being a very old unit, i dont know what temperature sensor is in there? i tried number 8 and 5 in the configuration but no success.

Problem 2: the extruder motor wont rotate. it makes this loud noise, but dont see it rotating. I also tried altering the stepper driver potentiometer up and down but nothing changed. Not sure why isnt it rotating, maybe because it is trying to push to feed in but because of the material meting shut the gateway, dont know.

Any help will be appreciated.

Thank you.

Re: How to identify a temperature sensor on a solidoodle

You know there is a safety feature in Marlin that prevents extrusion if the hotend is not to the required temp? The sensor should be the EPCOS 100K Thermistor.

Re: How to identify a temperature sensor on a solidoodle

Yes i tried the command M302 S0 to run the motor.
Well i found the issue with the motor. As suspected, the material was stuck in there, so i have cleared everything out.
The EPCOS 100K is number 1 in the Marlin config. I already tried that but doesnt give me accurate reading.

Re: How to identify a temperature sensor on a solidoodle

So under config i selected "51". and this is what it shows on the software. The software shows the extruder is upto that temperature. I used a digital thermometer to check and it shows 100-110F

Re: How to identify a temperature sensor on a solidoodle

No, it should be 1 or 6 as the pullup is a 4.7k.

I already tried both, did make any difference.

Re: How to identify a temperature sensor on a solidoodle

If you still get the same value even with a different pullup then your board ,wiring, or thermistor is bad. Try connecting the hotend thermistor to the bed connection on the board and see if you get the same value. Also try just having the thermistor in the air instead of mounting in the hotend. It could be shorting out due to contact with the metal hotend parts caused by one of it's leads being exposed.

Nothing is working with this. In the air, the sensor has minimum reading, as soon as i connect it and start the heater, it starts increasing drastically and within 30-45 seconds, the temp is up.

Re: How to identify a temperature sensor on a solidoodle

So does the bed thermistor behave the same? Try swapping the plugs at the board and see if the problem follows the plug or stays on the same channel on the board. If it reads right when just hanging in free air then it could be shorting to part of the hotend.

That is usually indicated by a constant high or low reading thought and you said your does climb. What I am confused about is that you image show a set temp of 275 and a reading of 275 so is not really that hot? You can't measure a hot end with an IR digital thermometer. It has a to be a contact type like a cooking thermometer or a K type thermocouple connected to a DMM.

This unit doesn't have a bed thermistor. It is a 120 VAC bed heater that connects separately.

Your board should still have a bed input on it though.

We are just trying to narrow down if the issue is with the thermistor, board, or firmware.

Re: How to identify a temperature sensor on a solidoodle

I guess i got it to work. You were right, the IR digital thermometer didnt work. My kitchen thermometer showed 100 when it was 200 on the software, but accidentally the head fell on my hand and YES, it was pretty hot. Lol. So i guess it is at 200 C.
Now, i tried extruding a material down the line with the stepper motor, but it gets to a point in the line and stop moving. The motor is still rotating, trying to push it in, but it wont. Maybe the head is not hot enough to melt a material?

Re: How to identify a temperature sensor on a solidoodle

You will need at least 220 most likely to be able to extrude. When you extrude a long line it pulls heat from the hotend. So if you are marginally too low it will simply be to low to melt.

Re: How to identify a temperature sensor on a solidoodle

The nozzle was a little block so we had to clear it up.
I tried manually extruding and it work. But now another issue, that i got 2 streams coming out of the nozzle?

Then you still have some sort of blockage. Clear it out completely.

Re: How to identify a temperature sensor on a solidoodle

OK so here is the update.
I cleared the nozzle, blocked it again, and tried clearing it out but not without breaking the tip. Lol.
So i ordered a pack of nozzles and heat tape to fix the sensor on there. Things look good now, ohh but wait, how it can be that simple, not for me.
The extruder motor runs fine when in manual mode, its calibrated and is perfect. But when i do the slicer and run it on automatic, it wont run. nothing happens. all other axis do what they are supposed to do, but the extruder wont run.

After slizing, here is the G-code. I added the M82 under configuration but nothing changed.

There are no commands to heat the extruder in that gcode if that is the complete beginning. So all you are doing is grinding filament. you either don't have an extruder listed in your Host or you removed it during an edit.

Re: How to identify a temperature sensor on a solidoodle

i downloaded the latest version of repetier and has the same problem.
how do i list the extruder in my host ? I thought these setting should be pre-defined.

Re: How to identify a temperature sensor on a solidoodle

Ok so this happened. I calibrated my Z so that its paper distance away from the nozzle.
