UV Led Connection with ramps.

Hey Guys,

Am trying build a new machine with the help of Nano DLP.
I needed help with the wiring to set up connectivity between UV LED CHIP and RAMPS.

If you could share the pin numbers for connecting the UV on RAMPS.

Thanks in advance.

Re: UV Led Connection with ramps.

The ramps output that is usually for the PWM fan is D9 and is usually used for the UV LED power supply ( you cant directly connect the LED chip)
It can be controlled with gcode
M106   or M106 S255   = ON
M107 = OFF

Thank you bigfilsing.

And also what is the optimum wattage of UV Led chip - 10/30/50/100

Re: UV Led Connection with ramps.

There is no real answer to that
IF you take the smaller machines like the KLD 1260/YHD 101/ D7  they have 20watt UV sources ( 2 X 10 watts) with some later models now having 40watt ( 4 X 10watt)

There are also a lot of people developing arrays of 3 watt LED's to give a more uniform light emission
you should take a look of the google+ group where many Opensource developers hang out.

Re: UV Led Connection with ramps.

Hello...you'll need to find out the rating of the transistor/MOSFET that is used to switch the pins on the Teensylu. If your power requirement fits the rating, you should be able to hook it up directly.
If not, it's relatively trivial to set up a relay.
