Sunhokey auto level firmware MKS gen 1.4

thingiverse

UPDATE: I've uploaded a second configuration file for Repetier firmware. It's come to my attention that I edited both files after downloading them from the online tool. The first Configuration.h is for version 0.92, while the second is for version 1.02 and clearly marked as such. I strongly advise against uploading these files to the online config tool, as the options at the bottom may not align with the actual configuration, potentially causing confusion. As always, be prepared to shut down your printer in case of any issues. UPDATE2: This firmware is specifically designed for Repetier. UPDATE3: If you're using the stock mount, you might need to reverse the direction of the X axis. If you have any questions or concerns, feel free to reach out and I'll do my best to clarify and resolve any issues. After dealing with manual leveling for a long time, I've finally created firmware for a modified Sunhokey kit printer. However, I'm still unsure if this is the right approach, as I'm experiencing some height-related problems. Those who have followed my work or read my bed leveling posts know that I believe these sensors are not accurate enough. I'm using an 18 mm NPN sensor with an 8 mm sense distance. The hot end mount can be found on Thingiverse, specifically this model: [https://www.thingiverse.com/thing:2261050](https://www.thingiverse.com/thing:2261050). The extruder gear is known as the MK8 Hobbed type and will require e-step retuning after upload. The sense line connects to the Z min endstop marked S, while the other wires are connected to the 5V and ground of the mks gen off on the left side of the board. Further testing is necessary to determine accuracy. Although I'm still unsure about this approach, I've made the firmware configuration.h available here. The key points to keep in mind when using it include the starting script for auto-leveling, which begins with a G28 home all command, moves up 10 mm (z move), and proceeds with a G29 S2 probe three-point, store average height command. My slicer has the starting gcode of "G29 S2;G28 X0 Y0;" without quotes. However, this doesn't seem to be correct, as I'm still experiencing issues with probe height calibration. For now, I recommend following a YouTube calibrating procedure for this issue. NOTE: If your printer is not configured like the picture, this may not work properly.
