![]() Notice that this protocol recommends a max acceleration of 4600 mm/s 2. The basic information we need to extract from it is the frequency under the MZV protocol, in this case it’s 39.4Hz. In this video:, Marc explains how to analyse the generated graphs. Please notice: If you are using a toolboard, the accelerometer might be incorporated, check the supplier datasheet. Further details on how to wire the ADXL can be found here. Unpower your machine before connecting the sensor to the control board. Use nylon washers (or print your own if you have a working 3D printer available) when installing the ADX元45 to avoid damaging it, PCB boards are weak and need to be handled with care. On the front of the EVA3 assembly, there are two holes for mounting the sensor with M3 screws. The ADX元45 must be mounted to the toolhead. There are two ways of calibrating this feature: automatically with an ADX元45 sensor or manually, the first method is the easiest and most effective although very good results can be achieved manually. The input shaping algorithm is an open-loop control technique that cancels printer vibration by creating an opposite signal. This makes it mandatory to assure the mechanical assembly is rigid and smooth before this calibration. Those should be checked and fixed first, if possible as described in the Klipper documentation. Note that ringing usually has mechanical origins: insufficiently rigid printer frame, non-tight or too springy belts, alignment issues of mechanical parts, heavy moving mass, etc. Ringing is caused by mechanical vibrations in the printer due to quick changes in the printing direction. Then proceed to insert: ⚠️Replace the BOLD text with your values.⚠️ PID_CALIBRATE HEATER=extruder TARGET= temperature Step 1 - PID tune Type the following command into the console in Mainsail: M106 S128 This will enable the part cooling fan at 50% speed. The part cooling fan should be turned on during this calibration as PID tuning must be performed in conditions as similar to a print as possible. ![]() Regarding the Bed temperature, it can range from 60✬ (PLA), 85✬ (PETG) and 110✬(ASA/ABS), a happy midpoint would be 90✬ (BED). If you use PETG, 240✬ or 260✬ for ASA/ABS If you print everything from PLA to ABS regularly, pick a happy midpoint like 235✬ (Hotend). The temperature parameter should be set to the temperature you expect to print at. This calibration must be done for the hotend heater and the bed heater. PID tuning will sequentially power the heater on and off to understand its thermal behaviour, it’s recommended to perform a PID tune for the temperature which you will print at the most. ![]()
