Quotecozmicray Laser should be connected to 12V supply from DZT 's Store website ---- PWM/TTL:support . TTL 0v off ,5v on so supplying 5V to the TTL should trigger (turn ON) the laser The TTL is modulated by a PWM signal from controller to get various power output (longer pulse width --- more laser ON time) What firmware and software are you using? Many of SW programs allow selection ofby alex97545 - Laser Cutter Working Group
Quotefrankvdh The +12 & GND on the laser are connected to the power supply. It looks like this software is for a CNC machine with a motor-driven spindle. I guess you could use the motor on/off signal to turn your laser on/off, in which case you would connect the laser ttl+ to D10 and the the ttl1 to GND. What wattage laser did you buy? Please post back how well it works. I connected the lby alex97545 - Laser Cutter Working Group
I bought 1wt laser. And I've connected everything you told me but the laser turns on when I turn on the power supply, and it just always works without any interrupt.by alex97545 - Laser Cutter Working Group
I have bought a laser And I've built a coordinate table wich consist of axis X and Y but I didn't find pins in the firmware (It is attached) where I should plug in the laser power 12v+- and ttl+- with ramps 1.4. I've read other topics so I burned one arduino and I didn't understand how I should plug in the laser. Thank youby alex97545 - Laser Cutter Working Group
