I used 24 V heater cartridges rather than the 12 V ones that came with the hot end This amount of power will quickly raise the temperature of the nozzle! It then becomes very difficult for the PID control schedule to harness that power (e.g. You can calculate the resistance roughly by using the formulas: Example, reverb is on the top, edison under it, and autotune on the bottom. To find out for which voltage the cartridge has to be used you can measure the resistance with a multitester/multimeter. You can just have it on the same channel and put autotune under Edison, the effects stack down so Edison records anything above it in the effects panel. (Not long ago I've had a similar experience with a 12 V cartridge in between my 24 V spares.) Thermistor settings: #define TEMP_SENSOR_0 6Īs the heating curve is very steep, it could be that the wrong cartridges are inserted, or you have been supplied the incorrect cartridges. Weird gap in second attempt was verifying that the right sensor was plugged into the right mainboard pin (no power going to hot end at this time). Here is a chart showing the temperatures of the hotends and bed while running autotune on T0 and T1. Should I try reducing the current to the cartridge? Currently set to default of 255?Īre there any other PID changes I should make to allow the autotune to figure out the right parameters to use?Īre there any other tests recommended to figure out why the hot end heats without being stopped by Marlin? After failing to get the hotend to heat properly, I have the following questions: Aditionally, I have the thermisistor settings to use config 6 (rather than 1) after reading through user recommendations on the hot end. After looking through other online messages, I used 24 V heater cartridges rather than the 12 V ones that came with the hot end. When I start the autotune, the temperature spikes pretty quickly and quickly fails, either heating to 60 ☌ or 200 ☌ ( M303 C5 E0 S60) for either hot end (E0 or E1). Working on upgrading my Ender 3 to a dual extruder setup using the Winsinn dual hot end and MKS Base V1.6 motherboard using Marlin FW 2.0.5 and am unable to get the PID autotune to work.
