As the title says, any advice on using an SV08 hotend on the Zero? Basically I got a clog so bad it was just worth buying a new hotend, but I’m impatient and just Amazoned a SV08 hotend after seeing that they were practically identical, but it seems like it’s not exactly plug-n-play. Klipper error: `MCU 'extruder_mcu' shutdown: ADC out of range Sensor 'extruder' temperature 21812.802 not in range 0.000:355.000 This generally occurs when a heater temperature exceeds its configured min_temp or max_temp. Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown` and the screen on the machine itself just says error 62. Any assistance would be appreciated Thanks ---

They’re not interchangeable, and frankly, the Zero’s is much better. The SV08 MAX is using the same one as the Zero. ---

That’s unfortunate. I just needed this one to temporarily work until I can get a proper replacement, which would take a while. ---

in another forum thread there is already a discussion on using the MicroSwiss Hotend for SV08 as a replacement, it brakes down to an issue of the different lengths(need to add a 15mm riser block) and the different thermistors values and then an issue of replacing some screws + cutting the plastic cover of the tool head for the fan. its all very simple in theory but in practice its a matter of your skill. as for a quick replacement i did get my replacement hot end very quick for sovol by about a week after order from the China warehouse to US. ---

The Zero is set up for a PT1000 temperature sensor. You can change printer.cfg to a generic thermistor BUT the pull up resistor soldered to the toolhead board is optimized for the PT1000 and will not be as accurate with a generic thermistor. The Sovol PT1000 is too large to fit into the notch in the SV08 heater block. Triangle labs sells a PT1000 that fits the SV08. Your bigger problem is your eddy sensor is going to hit the bed before you are close enough to the bed to print.
