Remove the voltage limit of the cooling fan of the 4max pro nozzle

thingiverse

Anycubic 4max pro is a machine released 2 years ago. After a long time of use, the fan will decrease the air volume due to long-term wear and tear. Of course, the solution can be to replace the new fan. However, it is found that the cooling fan firmware at the nozzle has a limitation (when the fan speed is set to 100, the voltage obtained by the fan is only 8.5v). Upgrading the V1.2.3 firmware can remove this limitation and enable greater air volume, so that small models can be printed. more beautiful. ———————— From Google Translate anycubic 4max pro是2年前发布机器，使用久了之后风扇会因长久磨损导致风量下跌，当然解决方法可以更换新风扇。不过发现喷头处散热风扇固件有作出限制（当设置的风扇速度为100时，风扇得到的电压只有8.5v），升级该V1.2.3固件能解除这个限制从而能更大风量，使小模型打印得更漂亮。
