Easy install. I like that this is a complete unit; direct swap for existing hot end and drive unit. Instructions could be better.

I suggest taking a picture of your existing connections prior to disassembly as the connections are direct swap. Also reduce your retraction settings and speed. Keeping your original settings could cause a clog in the hot end based on research I did online. I changed my settings from 5 to 1 mm on the retraction  Filament Fusing

48 watt with pwm 3.3v 0-5v


40watt unit that connects directly to ender

Conclusion: The 24 volts needs to be tailored to send  to give a ttl signal of around 3.3 volts for the 48 watt laser.  Use an opto isolator as below.


 PMW0-3.3V or 0-5V control signal can meet the control of the laser head.
