new build cannot get it to work

ddhoff17 · September 23, 2019, 6:04pm

I am a noob all around, both with cnc and computer programming. I ordered everything from V1. Put it together but cannot get anything to move. I have power to the board and to the LCD. The green light on the board is solid green, (not sure if that matters). I can toggle through the menu on the LCD, but nothing happens. I open repetier-host, it says it is connected, but nothing will move.

The lcd flashes “?” after the x,y, & z.

Andruino is asking for a setup code. Not sure if this matters either. I have been reading and futzing for 2 days. looking for a little help.

Thanks

Hello, you are getting a power light but is your Status LED lit? If not check you F2 Fuse which links Motors.

I hope that helps some.

Does your machine have endstops? If so, try homing the x and y axes. If not, try issuing a g92 x0 y0 z0 command through repetier host and then try moving around (in small increments).

update: good news, I can now move the X,Y,Z axis using the LCD. the problem was with my wires connecting to the board. I had to remove the wires from the jack and wire them individually into the card slot.

I still have the problem of my computer communicating with the board. I can open Repetier and it says it is connected, but nothing happens when I try to move it manually.

Is it connected to the right port?

the board to my computer. i am getting an error in the andruino when trying to upload .

You really shouldn’t use arduino. It’s already flashed from Ryan, so there’s no reason to do that again.

The problem is probably something simple. Try the repetier instructions from the top. Make sure you’ve got the right port and the right baud rate.

ddhoff17 · September 24, 2019, 9:15pm

I have the right port and baud rate. I have unistalled andruino from the computer.

I followed the instructions for repetier -host.

my computer does not recognize the board.

I can save something to the sd card and it works great from the LCD but nothing from the computer.

Do you have the usb drivers installed for the rambo?

You are seeing my files on the LCD there is no reason to flash the board. It is working as it should the USB errors must be on your computer end somehow. I suggest just using the LCD for a while. you do not need repetier if you have the LCD.
