Mosquito Hotend PT1000 issues
-
@wcmartino I doubt it, however they will probably need different ADC corrections. Your new board will have had the calibration done and stored during testing; your older board will not. That's why I suggested you perform the calibration. PT1000 sensors are more sensitive to calibration errors than thermistors. Are you sure that you performed the calibration correctly on the older board?
-
@dc42 Yes, tried it several times, nothing helped for either sensor. Will have to revist it antoher day, I already have the printer put back together.
-
@wcmartino what L and H corrections did the calibration process report?
-
@dc42 Ok reconnested the board. With the sensor disconnected H reports -6. Jumpering the connector on the effector and running the l999 says correction is 1.
With the resistor in place upon booting it shows -20.5C. If I manually set H to -127 I still show -15.3C.
-
@wcmartino have you tried using a different temperature input?
-
@dc42 Appoligies for the delayed response. I get the same results. I am good with running the nerw board on the Delta.
-
@wcmartino when and where did you purchase the original board?
-
@dc42 I purchased the board from Fliastruder way back in Dec 2020.
-
@wcmartino unfortunately it's out of warranty then. As the calibration process produces sensible L and H values, it appears that the ADC is working correctly. You could use your multimeter to check that the thermistor series resistors R60 R61 and R62 read correctly. They should each read 2200 ohms with nothing connected to the TEMP pins.

@dc42 No worries, I know it is too old. For now I have a new board installed and it is working good. I will mess with the other one when I have some free time. Thanks for all the assistance on this.
