使用HGX齿轮组的 Stealthburner 挤出机

裁切了main_body-hgx ，将裁切的部分添加到cable-cover-for-pcb-TMCfan。 并支持2007风扇为CAN bus TMC2209散热

2007风扇需要与热端风扇并联 或者单独接线到主板单独控制

Stealthburner extruder using HGX gear set
Trimmed main-body hgx and added the trimmed part to cable cover for pcb TMCfan. And support 2007 fan for CAN bus TMC2209 heat dissipation
The 2007 fan needs to be connected in parallel with the hot end fan or wired separately to the motherboard for separate control
