DLC32 v2 Laser is always on #383

Everything works perfectly except that the laser is always on and to turn it off I have to disconnect the general power supply. I would like to know if the problem has been solved, or if it is a defect of the Board DLC32 v2 that does not work. Can it be solved or should the BOARD be replaced? Thanks for the replies.

I connected everything correctly. I attach image of the laser module where the DLC32 v2 board is connected to the laser module

I also measured with a tester. Between pin S and TTL I always have 12.35V. I tried giving the commands M4 S0 - M5 S0 - M8 S0 but with negative results.

Is it possible to have a wiring diagram to understand where the problem lies? And the mosfet to replace Q1 (WSF40N10)? On J18 I always have a voltage of 12.35V

Ho trovato questo ma non so se è corretto. 141254561-9beff8f3-cf33-4f91-b388-e8c52febef84

don't use the TTL USE THE Spindle. if you found the schematic of v2.x then chech with the schematic of V1.x and you will see the differences between the two. V 1.x will work. V2.x won't.

Is the spindle output ok to control the laser? So you're telling me that the 3-pin TTL output doesn't work in version 2.1 boards? Unfortunately I don't have the wiring diagram.

If anyone knows how to make the links please use the picture and re-post with the correct links. Other people may benefit. Thank you

May be of help to others who have the same Laser.

If it doesn't work, it means that the board is faulty. Surely the WSF40N10 Mosfet is faulty.

Ask for replacement or replace the Mosfet at your expense.
