Hi everyone. I didn't really know we're to put this so I decided to put it here I just want to give back to the community because I have learned a lot from the site it is a auto zero for a cnc laser here is a video of it being used and I will also post a code that goes in mach3 here is the code...

hi how are you i just see the power supply you build for a 40w co2 laser would they any way i could get the plans from you Thanks Randy

OK i bought this and driver that came with it does not have TTL in put so i bought the relay to try to turn the laser driver on/off because it dose have a TTL input but if it will not work then i will buy that 2w laser driver that has TTL 2W 445nm Laser Parts Kit Large Heatsink and Fan | eBay

sorry 2W TTL 445nm Blue Laser Diode Driver 8 14V Step Down Circuit w 2 5A Output | eBay

sorry they might be a misunderstanding I wanted to use that relay to control that driver I bought from Rick

OK thanks what do you thank about this driver dose any one bought one

I am using it on a CNC don't know how often i will be switching the laser maybe a lot and for the laser it is a 2w blue that i got from Rick http://i.ebayimg.com/t/2W-445nm-laser-parts-kit-large-heatsink-and-fan-/00/s/MTIwMFgxNjAw/$(KGrHqZ,!nwF!ITPdOc3BQS!Wob6BQ~~60_57.JPG

I want use it to turn the laser off /on i did find this but can't make it out

hi i received the 1 Channel 5V Relay Module it did not come with any instructions can some one help me with i am using it to add TTL to a driver need help wiring it up Thanks

Thanks for the reply i bought a 1 Channel Isolated 5V Relay Module Coupling For Arduino PIC AVR DSP ARM will this work if it will where does it need to be wired between the driver and laser or between the power and driver

I did try that to i dont have another on the way but i do have a drive that dont have the TTL but would like to add it to it is they away to add TTL that driver ?

it all wired right i thank it is a bad driver i have another one are a way to add TTL to a driver that don't have it any one

I have a another driver are they a way to add a TTL to it someway

hi i don't if any one here has bought one from him i did last week a 2w laser and that thing work real good i thank it might be over 2w just to let you know

Power Supply Driver F 808nm 850nm 980nm IR Infrared Laser Diode TTL 200mW 1000mW | eBay

Hi when the TTL is wired up the laser loses power bad it powers on/off like it should but no power Mach 3,TB6560 board i have it on pin17 i have a another driver are they a way to add a TTL to it someway :thanks:

Are they any to add a TTL to a driver so i can use it with mach3

i am putting 2.2v at 1.3a its cut dark paper and burns wood but 1w should do better then that i tryed 2 drivers 1 i order and 1 lm317 i put together it works the best

That pic is wrong they are not 1w at all i bought some they want cut 2mm foam all the way with a good drive i know a 200mw will cut 2mm foam all the has any one bought them what do you thank like to here somebody elas

no the links are what i put together laser,driver,housing can you see why it would not work together the drive is 1.8v at 1.2 amps and the laser need 2.2v at 1.2amps for max power would a lm317 driver do better
