T2L not responding
« on: March 04, 2018, 07:18:35 AM »
For some reason T2L doesn't work anymore.
I tried EleksCam and everyyhing work OK
T2L send the gcode but the mena seem not responding
Also I can't get the axis to move manually
Tried disintalling T2L and reinstalled but with no effect

A3 2.5 watts laser Mana SE board.
1K resistor installed on laser module

It sounds like you are not connected, are you getting the Grbl Ready message?

Likely you plugged the machine in a different USB port and the driver was assigned a new COM port, just disconnect and select the correct port again. You can right click the big red button or select disconnect from the Machine menu.

the CH340 port dissapear. And when I try to re-installed, it tell me is already pre-installed in advance
So I try to uninstall and a message say: no device is found.
Restat the laptop many time: no success.

I'm stock I don't know what to do anymore

Have you tried another cable?

Did you check the device manager? If there is a problem with the driver, you should see a yellow exclamation mark.

But what I don‘t understand: using the elekscam works with the same usb port and same cable? Then there is no driver problem, but somehow the communication between T2 and the Nano on the board is disrupted. So try again:
1. see, if elekscam still works
2a. if no - the problem is driver or cable related
2b. if yes - the problem is between T2 and your board. In that case only T2 actions, as Zax said above, are required
3. if it is a driver/cable issue, here is a link to the Arduino forum, where you might find a solution. You don‘t have to install the ch340 driver through T2. You could also use the driver installation described in that forum thread (and make sure to use the right download location directly from the Chinese manufacturer of the ch340g):

Do you have already thought about a solution yourself or is a part of the problem sitting in front of the screen?

That doesn't sound good.
Did you read what the people tried in the Arduino forum?
I found another link where somebody (towards the end of the discussion) succeeded in first istalling successfully the driver on another PC and then copied some files back to his Win10 system. But this is a very unusual practice and on your own risk.

Question: do you use USB3 ports? They could be one source of the problem; some people, who have laptops w/o USB2 ports, connect USB hubs with USB2 ports to connect their Arduinos to.
Another, maybe my last trick: what happens when you exchange the Nano chip with another one, if at hand?
Do you have already thought about a solution yourself or is a part of the problem sitting in front of the screen?

It sounds like the "Nano" has failed, I would get another one as they are only a couple of bucks and see if that fixes it.

One of my friend is a computer network engineer told me since I have multiple computer.
And because for some reason my Arduino file are corrupted and affect the exiting laptop.
Do the driver installation to another computer. I ran the laser application.   ;D Well it work.
As soon as I start the first computer (laptop) the serial driver installed itself and my com port show up.
Now back to burning.
Question to Zax:
That laptop is operating with Win Vista is there any chance in a future update you won't support Vista.

Thank you guys for your help

Now time to register

No that's very unlikely, T2Laser requires .net 4.5 which is available on Vista and I have no plans to move to a higher version.

If I did, you would still be able to keep the latest version that was released for .net 4.5.

What software do you recommend for 3D printing.
My new baby soon.
Thank you
