Atif may have been having the same issue I am on getting the laser connect to work.
So from what I have understood
Atif asked regarding his diagram
Atif replied as i am remembering/recalling of memory about my failure is when i press fire on LightBurn and connect K- and K+ pin laser tube fire up.
But when i gave some sketch to draw the laser tube did not fire up because i did not connect of short K- & K+ pin
Atif then mentioned it is correct we need to short K- & K+ in MKS DLC 32 V2.1.
Now laser tube is firing up and working…
So my interpretation of this is Black from TTL on the Makerbase motherboard goes to ground on the psu next to IN. The green from S on the Makerbase motherboard goes to go IN on PSU.
If this work by connect and disconnecting the K and K+ one will go as test fire on the circuit and the laser when running a job.
