I got this error msg during uploading the sketch. What should I do?

What are you trying to do? Are you running the cnc tethered or with an lcd? Trying to cut something?

This is saying it can’t talk to the microcontroller. Make sure it is powered and you have the right port.

That is a little weird. It usually says more like 53%. But I don’t usually pay attention.

4

I’m trying to install the firmware. Do I need to install the attached lcd during installation or not?

5

You don’t need the lcd during installation.

I’m using 12v 15amp power supply Is it ok?

7

The fact you have a tab for sketch_something makes me think you don’t have the project open correctly. You should unzip it, open the Marlin/Marlin.ino file there and then compile/upload from that window.

That should be fine. Do you have the polarity right? Are there lights on?

These things are pretty hard to break. There shouldn’t be any way to break them over USB. I am guessing you have two problems. 1) not the right source code and 2) a connection error.

I’m referring to this while installing the firmware - https://www.v1engineering.com/marlin-firmware/ i get the same error msg.

Oh maybe my power supply is dead. No light on my mini rambo. Thanks @jeffeb3 @banjopete. I’ll update after getting new power supply.
