PT1000 + Mosquito Hotend on CR-10S Pro V2 Issues in the Final Stretch

[AlchemyCustoms]

I've made it all the way to the point that I can connect to the printer, but I get immediately disconnected due to my hotend reading 140375333.7°C... I think it's a bit cooler than that; so rather than force my way through that, I thought I'd ask if anyone has any experience or input on this.

Mainly I'm just trying to figure out where else I can tell the printer that I've changed the thermistor out for a PT1000... It looks to me like the Marlin firmware natively supports it, but it also looks like Klipper does too, so I'm confused on if I have a hardware error or a software problem!

I've been at this for HOURS now... losing my mind. Other things to note: Installation is based on KIAUH script inside of a Debian Buster Docker container on my Unraid server. Printer has the Mosquito hotend, and a Slice Engineering PT1000 and 50W heater. Wires all appear to be in good order from what I can best tell. Thanks in advance for the help, I appreciate it greatly!

Hi, were you ever able to get this fixed? I have the exact same setup and issue and I've been pulling out my hair for two days now.

[AlchemyCustoms]

Yep, I've got ya Zyorg12.

I've come quite a long way since this post so I'm feeling pretty confident I can help ya out. Message my business page on FB if you need me to just chat with you about it for a bit so we don't clog up the forums. That being said, I've attached my config and everything relevant for the CR-10S Pro V1/V2 (I have the V2) below.

Also, please note that I am using the TYHI Net Mosquito Mount made by TYHI3D on Thingiverse, so my offsets, mesh bed leveling points, etc. will all be in accordance with that. I will point out that some of them aren't super accurate, so if you use the same mount and decide to dial it in more, I'd love to know the perfect points but haven't had time to find them myself.

Remove the hash tags in front of the lines you are going to use when you actually do the tests for them. Input shaping and Pressure Advance are critical on these CR-10S Pros... Made an insane difference for my print quality. It does take a good bit of time and a decent amount of filament, but it is respectable when you realize how much benefit it brings for the time and overall money invested in filament.

#This is the full hardware config with descriptions for using ADXL345 accelerometers with Klipper. Highly advisable for input shaper tuning.
#[adxl345]
#cs_pin:   #The SPI enable pin for the sensor. This parameter must be provided.
#spi_speed: 5000000   #The SPI speed (in hz) to use when communicating with the chip. The default is 5000000.
#spi_bus:
#spi_software_sclk_pin:
#spi_software_mosi_pin:
#spi_software_miso_pin:   #See the "common SPI settings" section for a description of the above parameters.
#axes_map: x,y,z
#   The accelerometer axis for each of the printer's x, y, and z axes.
#   This may be useful if the accelerometer is mounted in an
#   orientation that does not match the printer orientation. For
#   example, one could set this to "y,x,z" to swap the x and y axes.
#   It is also possible to negate an axis if the accelerometer
#   direction is reversed (eg, "x,z,-y"). The default is "x,y,z".
#rate: 3200
#   Output data rate for ADXL345. ADXL345 supports the following data
#   rates: 3200, 1600, 800, 400, 200, 100, 50, and 25. Note that it is
#   not recommended to change this rate from the default 3200, and
#   rates below 800 will considerably affect the quality of resonance
#   measurements.

#[resonance_tester]
#probe_points:
#   A list of X,Y,Z coordinates of points (one point per line) to test
#   resonances at. At least one point is required. Make sure that all
#   points with some safety margin in XY plane (~a few centimeters)
#   are reachable by the toolhead.
#accel_chip:
#   A name of the accelerometer chip to use for measurements. If
#   adxl345 chip was defined without an explicit name, this parameter
#   can simply reference it as "accel_chip: adxl345", otherwise an
#   explicit name must be supplied as well, e.g. "accel_chip: adxl345
#   my_chip_name". Either this, or the next two parameters must be
#   set.
#accel_chip_x:
#accel_chip_y:
#   Names of the accelerometer chips to use for measurements for each
#   of the axis. Can be useful, for instance, on bed slinger printer,
#   if two separate accelerometers are mounted on the bed (for Y axis)
#   and on the toolhead (for X axis). These parameters have the same
#   format as 'accel_chip' parameter. Only 'accel_chip' or these two
#   parameters must be provided.
#max_smoothing:
#   Maximum input shaper smoothing to allow for each axis during shaper
#   auto-calibration (with 'SHAPER_CALIBRATE' command). By default no
#   maximum smoothing is specified. Refer to Measuring_Resonances guide
#   for more details on using this feature.
#min_freq: 5
#   Minimum frequency to test for resonances. The default is 5 Hz.
#max_freq: 120
#   Maximum frequency to test for resonances. The default is 120 Hz.
#accel_per_hz: 75
#   This parameter is used to determine which acceleration to use to
#   test a specific frequency: accel = accel_per_hz * freq. Higher the
#   value, the higher is the energy of the oscillations. Can be set to
#   a lower than the default value if the resonances get too strong on
#   the printer. However, lower values make measurements of
#   high-frequency resonances less precise. The default value is 75
#   (mm/sec).
#hz_per_sec: 1
#   Determines the speed of the test. When testing all frequencies in
#   range [min_freq, max_freq], each second the frequency increases by
#   hz_per_sec. Small values make the test slow, and the large values
#   will decrease the precision of the test. The default value is 1.0
#   (Hz/sec == sec^-2).
