Mks Gen L and nothing!

I've fitted a MKS Gen L board to a CTC Dual and got Matlin 1.1.9 configured and compiled but then nothing I'm stuck again.

When I try to upload the compiled firmware to the board I just get a time out respond from the Arduino IDE which is running on a Win10 box.

I've tried changing Com ports ( only Coms 1 and 3 are offered as choices.) and set the baud rate on the PC to match that of the Marlin install not that it should matter.

As far as I can tell my wiring is good and all the plugs are in the right sockets

There is no sign of life from the board, no lights, no beeps, the only thing running are the fans on the hot ends and I don't think they should be.

The display seems to be RepRap budget item and it's not lighting up at any time even though it's plugged in correctly.

One odd occurrence was that when I tuned the steppers I could not get the voltage over 0.15v which doesn't seem right.

How do I find out if the board is defective? I've checked the board under a magnifying lense and nothing looks as if it's burnt.


Any advice much appreciated.

Thanks All. Aamcle

have you ever successfully uploaded firmware to this board?

are there any unknown usb devices in your device manager? as you do need to install a ch340 drivers. drivers here [sparks.gogo.co.nz]

This is the first time the board has been used I'll try that driver.

Thanks

I used that driver and still nothing, is there any way to check if the board is functional?

I'm now concerned that it may be defective.

Should the board have any LEDs illuminated or any other sign of life?


Thanks. aamcle

until it has firmware on it, it is basically a brick... you cant do anything with it or test any part of it.

I would try and install install a new bootloader [jgaurorawiki.com]

Once the boot loader is installed try uploading the firmware again.


All that error says is the arduino software can't talk to the boot loader on the chip, it doesn't give any clues as to what the issue is.
The most common issues are serial drivers, and no boot loader

Sorted I found another board and I was able to flash Marlin.

Thanks All.

I just received an MKS Gen L board purchased on ebay.
I've connected the LCD and power supply and powered up but all that happens is a slow beep and the LCD backlight flashes.
The power supply is connected correctly as are the EXP1 and EXP2 cables between the boards. There are no stepper drivers installed yet.
Is this board faulty or is this what should be seen until the firmware is uploaded?

Flip the plugs over, same sockets, just so the notched side is opposite where it is now.
