mini height sensor board - Differential IR Z probe mount for E3d Chimera

thingiverse

I built this setup so I could seamlessly integrate my mini height sensor board with my E3d Chimera and duet electronics. Sensor details are available below. https://miscsolutions.wordpress.com/mini-height-sensor-board/ I chose to print it in ABS, knowing its added heat resistance would be beneficial given its proximity to the heat block. The design mounts directly on the front of the fan for optimal placement. During homing procedures, I noticed the hotend was approximately 1.9mm away from the bed. To address this issue, I modified the G31 command in my config file to read G31 Z1.9 P500. With this adjustment, when homing is initiated, the hotend will be precisely 2mm above the heatbed. Once printing commences, the hotend will assume its correct height.
