Recommended Posts

For those led I would advise using a fixed current power supply so they are not over driven. Also they burn out very quickly if over heated. I would have a much more substantial heat sink in direct contact with them as well as the fan.

How it is mounted to printer head ? Just screwed ? Can you post some pictures how it is installed ?  What about this plastic part is is custom made stl ?  Also is it covering full plate as I seen most of UV solutions is  installed just on one side of printer head and not cure full bed .

Pulse width modulation purely acts as a dimmer control depending on the speed of the modulation.

It still allows them to be over driven.

Fixed current will remove that possibility.

I manufacture multi channel pwm controllers.

There are two nuts un first Photo you can see, It is true what reptilesink says, this is not recommended for hard work, I test it for common uv print  and it works well by adjusting the PWM to 75%.

Dear Reptilesink I use a MFR1100 for current, 11A PTC Replacement fuse for RAMPS which protects the heated bed output against over-current.

I have that one ...just wonder if it will perform better than air cooled ? How to override settings and make head goes far right to make sure it covers full platform area with uv light and cure ink .

With 40w of led which typically have a beam pattern of 120 degree it will cure all the platen area.

China Guys call it “60w”  what will be the best power source ?

Soon I will try the following water-cooled configuration, for hard work without stopping

Ideally a constant current power supply.

You will need to know the specifications of the led's.

had to cut the left side out to fit it and with most converted UV printers you don't get the full cure on the right hand side but being a flat bed you just move it to the left a bit and print good thing about rip software it lets you place your print where you want it on the bed it will print a full A3 size and the watercooled units are the best as the ink mist eventually clogs the cooling block on the fan cooled unit

Mount it on the side of the printhead and see if it hits when the head goes all the way over. If so then you need to cut out what it hits
