No, not while unplugged. But while nano is plugged and powered on.

T2 Engraving / Re: Mana SE led D4 blinking

Came across this thread.
http://forum.eleksmaker.com/topic/89/resolved-everything-stopped-working-blue-power-light-flashing-video
So, may be 16v capacitor is the problem?

Right. Tried that too. No difference. Tried with the nano that came with L7 board. So I think no problem with nano.

I have tried the suggestions. Flashed firmware to older version, then flashed again to latest. Took nano out and replaced with the one from L7 board. The problem remains same. I think it's hardware related.

I have tried to reload the firmware through T2. It was successful, without any errors. But the issue remains. Also not a power supply issue. Tried with L7 board.

T2 Engraving / Mana SE led D4 blinking [Solved]
« on: May 30, 2017, 10:50:58 PM »
I upgraded to Mana SE board for better pwm control. I hardly experimented on few images and after that the board stopped working. It's led D4. It's solid when working normally. Now it just blinks continuously after connecting to power. Nothing happens. I contacted banggood for this issue. Has anyone encountered similar issue with Mana SE?

Solution that worked for me:
Please go through thread if you have similar issue. Removing 16V capacitor worked. I will replace it though.

T2 Engraving / Re: Wiring for Mana SE to ttl laser
« on: May 12, 2017, 11:05:32 AM »
So I will just keep it like that. I thought I made a mistake in connection. I dont mind the fan running. The laser works perfectly as it should and responds to pwm signal nicely. One more observation, the spot size is much bigger than the original 2500mw, but no distortions around the spot. I will try connecting to S.

I have upgraded as per instructions. PWM works fine. Although one problem. The fan on laser stays on continuously at max speed. Any suggestions?

Do I need to connect both the gnd on the laser to the minus on mana se laser input?

T2 Engraving / Wiring for Mana SE to ttl laser
« on: May 11, 2017, 08:04:35 AM »
I upgraded to mana SE board and 2300mw ttl laser. Can anyone provide proper wiring instructions? I searched few threads but couldn't find proper answer. Please refer to pictures and suggest wiring instructions. I understand two connections for laser and two gor ttl.I don't want to mess up connections.

Thank you Zax for the reply. So I will go with Mana SE and 2300mw laser. Will update and post results. So far I am very happy with T2.

T2 Engraving / Advice needed for PWM upgrade
« on: April 26, 2017, 09:26:03 AM »
First I want to thank Zax for T2. I have been using it for few months and it's an amazing package. Please keep on updating and adding more features in future updates.
Now, my question. I am interested in PWM functionality to produce grayscale images. I have Eleksmaker L7, 2500mw. I can't get a linear response for 0-255. I searched some threads. So I am interested in buying new laser module, rather than opening existing one and making new connection and new driver. Will this work as a replacement? Suggest a link if it's not compatible.

Also, I am not sure about connections to nano. There are 4 wires. Can anyone guide me how to connect those? And if I upgrade to new Mana SE board,does it make wiring simple?

Any practical difference between 2300mw vs 2500mw?
