Ramps 1.4 board

Mostly Printed CNC - MPCNC Troubleshooting
1

I am almost finished building the MPCNC. Everything is assembled. I am testing the stepper motors on the ramps board before I install them on the printer. I have the ramps board communicating with repetier. When I first power up the board the motors click but I can’t get them to move or do anything. I have also tested in ESTLCAM. The board communicates but the motors don’t move.

I’m using the stock pololu drivers at the moment. I also tried DRV8825, they didn’t do anything either.

I did modify the ramps board for 24V by removing D2.

What is the best way to test the motors and the ramps board? It seems like something is defective but I don’t know where to start looking.

What exactly does this mean?

This is typically how we test it, https://www.v1engineering.com/assembly/software/

Your previous statement might mean that is not an option now.

Where did you buy everything?

Are you powering both the ramps and the arduino?

4

So, you flashed with estlcam firmware? You shouldn’t do that (stick with the Marlin FW).

I’m not familiar with that procedure. Your Power supply is 24V, and you removed a diode, so nothing is powering the arduino, except USB? Can the drivers handle 24V?

What evidence do you have of that? Do you get a response from an M115 command?

Normally, you should be able to move the motors in repetier, (or from the LCD, if you have it), and they will move even without all the mechanical stuff on there.

Ok, the Z axis moves from repetier manual control. Now I have to figure out why X an Y are not moving.

Your not giving us much information to go off of to help.

I think the root of my problem is keeping the arduino showing up as a com port in windows device manager. If I plug and unplug the usb cable enough time it will sometimes show up but usually windows won’t recognize it. Extremely frustrating.

Any suggestions on how to fix this? The arduino I am using is a clone. It uses the CH340 USB chip which windows doesn’t seem to like. I installed a driver specifically for that chip. It shows up sometimes, but it seems random.

On a mega 2560? That sounds like an older board, you might just want to upgrade to a 2560.

9

It’s a Mega 2560. A clone though.

10

Switch to Linux? Sorry, couldn’t be helped.

11

Yes, that’s what I’m working on. I’m setting up Ubuntu.

It is Mega 2560, but its a clone.

12

Shoot. I meant that as a joke. Do you know Linux? If it’s still a problem in Ubuntu, then you’ll know it’s the board, at least. Thee syslog might give you a clue.

There might be something wrong with this arduino board. It worked fine earlier, but I’m having a really difficult time getting it to work consistently. Sometimes it will connect sometimes it won’t.

 

Its connected on com3 and shows up in device manager now but I get this error when I try to flash it from the arduino IDE.

The arduino works fine the first time you install the drivers, but if you restart the computer, Windows tries to assign different drivers to the device and messes everything up. I can’t stop it from doing this.
