This is my first post in the forum and I just had to express my thanks to you Ryan for your innovative and inexpensive design. After years of searching for an affordable CNC, you answered the call with not just a CNC but with a multi-tool machine. I knew you would win the innovation contest back in July when I voted for your project. You made us proud.
I purchased the CNC bundle from this site and 3D printed the assembly parts. It took me a few weeks but I finally completed the assembly and had a blast doing it! I’m ready to start testing. I installed Arduino software to my Macbook. I plugged in power to the RAMPS board and plugged the Arduino board USB to the Macbook but it could not detect it. I figured the Arduino board might be generic so I searched and tried installing a driver I found at https://forum.arduino.cc/index.php?topic=261375.0
Now the Macbook detects the board but Pronterface or Repetier was not able to connect. I tried all the ports the new driver made available but it didn’t work. I could try my very old Windows XP laptop that I have stored in a closet somewhere but I use my newer Macbook on my 3D printer all the time so I never bothered.
I guess I could try looking for other Mac drivers but I was wondering if anyone had any luck on a Mac.
If not, I guess it won’t be a problem if I buy the Smart LCD controller. Am I correct in assuming I won’t need to connect with a computer at all as long as I have the LCD controller?December 16, 2015 at 9:26 am #5034
Thank you for the compliments! I have my fingers crossed for the grand prize this month from boca bearings to put half towards school loans, but I would also be ecstatic to get another 3D printer to ramp up production.
Okay you are the 3rd person now having mac issues. I would love to get this figured out and put it on the instructions.
Where I left off with the last person was this screen. https://www.vicious1.com/repetier-host/
I know on a mac the default settings are slower. try changing the baudrate and the rest to match. If that doesn’t work I will make a custom firmware to match the mac baudrate and see what happens.
ThanksDecember 16, 2015 at 11:59 am #5038
I read about how you built your 4 head design to keep up with demand! You, genius you!
I’ll try experimenting with different settings and there are most likely other Mac drivers for the Mega 2560 that I just need to try.
In the mean time, I ordered the Full Graphic Smart Controller from your shop so I won’t have to connect a computer. Letting a smart controller run the machine is convenient.
I’ll document my Mac experiments and let you know how it goes. Thanks Ryan!December 16, 2015 at 2:34 pm #5047
Yes, with one of the LDC controllers you will never need to attach your computer. I have one of the XXL LCDs on my printer and a Full Graphics LCD on my MPCNC and never miss attaching a computer to them.December 16, 2015 at 8:16 pm #5062
Awesome. I looked at some video reviews of the Full Graphics and the XXL LCD controllers. They are so many configuration options already built-in! Can’t wait to try it out.December 17, 2015 at 3:36 pm #5072
I decided to troubleshoot the connection issue with my Macbook a little later. I couldn’t wait to test out my newly assembled MPCNC so I pulled out my old Windows XP laptop, installed Arduino, Pronterface and Repetier. All of the software could connect and when I jogged each axis I saw the machine come to life! It’s so beautiful! It looks like I got everything wired up correctly on the first try! High-Five everyone!
Okay, so going back to the Macbook connection issue, I think Ryan’s suggestion of slowing down the baud rate is the key.
WatEng’s comment in the blog seems to confirm this: https://www.vicious1.com/marlin-firmware/#comment-2422
So editing the baud rate in the Marlin firmware to 115200 should solve it. Lowering the baud rate in Pronterface or Repetier on the Macbook alone wasn’t enough.
When I get a chance, I’ll download Ryan’s latest Marlin firmware beta from his latest blog post, edit the baud rate and see if works.December 17, 2015 at 3:38 pm #5073
Can’t you just change the default baud rate in repetier? Much quicker than messing with the firmware.
