Anyone any help?
I reordered the mana SE in case this is the faulty part.

RE: 5500mw laser module not receiving pwm signal?
Sorry for the late reply. Thank you zax for the info, I'm not sure how this will help, is this some kind of work around? It should however function with the 3 pins, right?
I have received the original eleksmaker cable to not mess any further. Unfortunately it had no effect.
I remembered when pluggin in my selfmade cable the connecton on the Mana SE bent ~45° (!), i gently pushed it back and now I fear i damaged the connector / connection to the board.
What can I measure or investigate to locate the problem? Anything I can read on the software?
I found that out that two of the three pins have a short. I can measure the resistance if this helps?
Red to yellow 497 Ohm
Red to Black 1.5 Ohm
All the pins from Mana SE to laser module are conducting
Attached screenshot and pictures of the unit with wiring. I appreciate any help!
5500mW laser module with pwm (3 pins)
Stepper motors ok
laser module connected, fan on, PWM led "blue"
weak laser turns on by hand (button 1)
full laser turns on by hand (button 2)
Connection through BCL ok
fimware 1.1e GBRL
Unplugged everything, turned on/off, no effect.
No "laser 1s on full power when connecting" (previously this happend every time)
connector on Mana SE bent
If I missed any information let me know.
PPS: Can i use the TTL connection instead (no regulation of laser intensity)?
5500mw laser module not receiving pwm signal?
I use the A3 pro 5500mW with a custom frame.
I extended all of the cables for my bigger custom frame. I made my own custom cable for the laser module and made both plugs the same orientation. The one sitting on the laser module (5500mw) is [b][color=red]red[/color][/b], [b]black[/b], [b][color=yellow]yellow [/color][/b]while the same orientation of the plug on the mana board should be [b][color=yellow]yellow[/color][/b], [b]black[/b], [b][color=red]red [/color][/b]. Can someone confirm this?
The first time i had switched the yellow and red cable, because who the hell would change the order of the cables? I turned it on for a couple of seconds and a blue led on the mana board flashed. The fan of the laser was dead. I found out this was due to wrong wiring.
Fixed it. Tried again. Fan is working, laser module shows blue led, low power and full power buttons on the laser board are both working perfectly.
But when using Software the laser is not working. Tried Bencutlaser and T2laser.
I measured all the cables plus the contacts behind the boards (backside). Everything is in place and connected. It seems the laser module is not receiving any pwm signal?! What else can I check?
Did i ruin the lasermodule? is it the manaboard?
Also the cable diameter is 0.22mm² which is imho smaller than before. Could this be the problem?
Anyone knows where I can quickly reorder the correct cable? I didn't even find a source for the correct cable in small sizes. Very frustrating.
Thank you all!
RE: Lens Replacement / Upgrade (5500mW)
I ordered this one: https://www.amazon.com/405-G-2-Glass-Aixiz-Laser-Module/dp/B00B6DOA0G .
Posting to not forget this thread and give you feedback.
PS: My manually focussed 5500mw does not look like a dot. Its in the shape of a very thin/small ellipse with a dot in the center. Anyone else have this issue?
