@Zax I actually tried to use 0.9j, and made the changes as mentioned above, it still does not recognize it .
What is really BAD is the laser is turned on on reset, full blast .. and this is a known bug for many moons.. it is to me a major flaw, and to rectify it would cost almost nothing (pull down resistor), a 0805 could be soldered on the 4 pin connector to fix this. Cannot understand why they keep producing this controller without the modification, it is dam serous !!. In the end I added a FET to invert the TTL signal, with a 1K pull-down on the 4 pin connector (PWM to GND) it now works. Thanks for you input.
@coralie-Fr It sounds like a broken cable or bad motor driver, you can test by swapping the cables at the Mana board - if the fault moves you know it's the cable if not it's likely the stepper driver. Then swap the stepper drivers and make sure it follows.
I have settled with the "Moski" CNC 1310 as it features direct drive and 10mm Aluminum components.. although for all intents its the "Deluxe" Eleksmill. This features an M3 thread in the top support plate. I have purchased the Eleksmaker 2500mW Laser, found a similar issue in terms of securing the laser.
There is a little margin around the mount, I have simply shimmed this with thick card to center it and made reference marks on the Y-Axis table to ensure its centered.
Remember any slight movement will throw out any precision etching.
I had the same issue until I realized I'd connected the Y axis Stepper motor to the wring connector on the Controller board. Once I switched to the connector nearest the X axis, a shown in the included picture.
