the firmware_rumba has unofficial RAMPS support provided by the community. We don’t officially support RAMPS.
This is a known problem with the newest versions of OSX. We don’t know anyone that’s solved it yet. I don’t have the latest version of OSX because my laptop is 5 years old (and still going strong!)
We don’t have the man power to run a live chat. We’ve worked hard to improve our guides and would love your ideas how to make it even better. Please email us directly and we’ll try to help.
The picture at the link is correct. Notice that the 5v and GND wires switch order.
There are many reasons a servo could die – wear, hitting something and breaking internally, incorrect voltage… none of these things should be a problem for a new servo from us.
Yes, the A4988 drivers are what we use in the RUMBAS for the Stewart Platform.
What do you mean, “does not stop moving”? Are you using a continuous servo instead of a 180 degree servo?
Firmware can be downloaded from this site, here: https://www.marginallyclever.com/product/makelangelo-firmware/
The firmware_ams folder contains the UNO version of the Makelangelo code.
Post a picture of your setup?
FWIW, I’m connecting random RUMBA boards from my inventory.
In Windows 10 every unit is showing a COM* port and I’m able to upload firmware.
In OSX every unit is showing a /dev/tty.usbmodem* port and I’m able to upload firmware.
Can you tell me your order #? I want to find out when your order was assembled and by whom to narrow down what could be causing the issue, if it’s on our end at all. I suspect it’s a problem with OSX Sierra. Evidence here:

https://forum.arduino.cc/index.php?topic=442698.0There is no obvious way to connect a laser driver to the L293d motor shield. Also…that sounds really dangerous. I do not recommend this.
No, I don’t. I can’t guarantee that UniversalGcodeSender works with GRBL.
Yes. Run the software, open settings, and set your machine type to 2.5. You will then have options to change the machine size (3×4) and the paper size. 11×17 sounds like US legal, maybe? Should be fine.
I understand a bit better now. uncomment
#define MOTHERBOARD BOARD_RAMPS
and make sure other MOTHERBOARD lines are commented (lines must start with //)
Note that RAMPS is not officially supported and I have not tested it, ever. Please report back with your success.
I’ve added SVG to the developer version of Makelangelo. Spiral drawings saved as SVG make nopaste, imgur, and several other online sites choke. Inkscape eventually loads the SVG. Other formats seem to be OK.
In a perfect world you’d make a pull request from github with the changes. that way
– your name would show up in the credits if future employers look for your name; and
– you know the code works right because you tested it before making the pull request.…but I can do it if you give me the details, and we’ll cross our fingers that it works.
As far as I know there’s no way to load bad Arduino code onto a board such that the USB does not load. I mean, the USB has to load so you can send the code to the Arduino!
Are you flashing the bootloader? That should not be necessary at all.
SVG export might be doable. I guess I start here? https://www.w3.org/TR/SVG/intro.html
If the wires are plugged in backward, the screen will not light up or will display garbage. I don’t recall any beeping before. Picture of your setup?
I normally use Inkscape and I tested the DXF files against Inkscape. Is there any more detail about the Adobe Illustrator problem? Any error message, log file, anything?
The DXF file format is quite extensive. I did the minimum require to make it load in Inkscape, I admit that. Presumably as a workaround you can load in inkscape, save it again to illustrator (or even back to DXF!) and then Illustrator should be able to load it OK.
Two people means it can’t be just user error.
I doubted you and that was my mistake.
I’m sorry I didn’t help you faster.Ok, I’ve asked the original equipment manufacturers. I’m getting to the bottom of this. Thank you for your patience and understanding.
Ok, now that’s weird. I need to find a copy of newer OSX to test this for myself.
I wonder if this is related: Sierra doesn’t seem to support some USB drivers very well:
https://forums.developer.apple.com/thread/61472
“The use of a Fresh Roast SR700 Coffee Roaster also crashes Sierra because of this CH340 chip usb/serial driver incompatibilty too.”
CH340 is used in several arduino clones. RUMBA is merely arduino-compatible, it may be victim to a similar issue.
Did you dig into the code at all? If you try “G0 F100” and then “M114” does it report that the feed rate changed to 100?
Maybe.
Perhaps you should reconsider why you are building a CNC machine when you can buy one for less effort.
You will have more success asking the developers of GRBL.
To use GRBL software you must install GRBL firmware on arduino.
