It's mechanical problem... I set the correct voltages and this belt system is a crap, much work to loose or tight and never comes fine... a waste of time and money... the quality of these parts are poor and if you tight/loose brackets and supports too much it will crack...
I'm very very frustrate with eleksmaker... the documentation is poor, don't has a troubleshooting guide to set these problems... but no... china is ever china quality...
My laser diode, that was installed at this module was degrade shortly, after one month of a making the foto and then cutting them. I find the 6W diode on the EBAY and soldered it on the place. The voltage is 4.2V, but the current is low - only 2A so, I have only 3,3W of the laser power. It can work on a 6W. Somebody know, how to add some mA's from this driver board? I think, that this operates by the VR1 variable resistor, that is not present on the board... Can somebody help me? )
(You can see the work of original laser diode from eleksmaker on my video here https://youtu.be/5HzGsgfeAPU, and a litle lifehack with air flow using the compressor - I make it for the russian auditory, so the language of this clip is russian, if You need some questions, I'll be happy to answer)
@Dominykasssx I can't give you an exact value, but I would start with a 10kohm (1/8W would be ok) and if the laser doesn't turn off you go lower until it does. If it's not turning off by ~1kohm then you probably won't find a solution that works.
Say a 2.2kohm turns the laser off when disconnected, then you must check that the laser turns on with software control (TTL input connected).
FIRST follow these STEPS before posting a question.
DO NOT SUPPLY POWER TO YOUR LASER OR THE CONTROL BOARD UNTIl INSTRUCTED TO DO SO BELOW
Change Regional Setting DECIMAL , to .
