I recently purchased a completed but used mpcnc with the impression that all I would need to do is install the software to make it work and tadaa it would. After you stop laughing, maybe you could help me get it going. I have installed (to the best of my ability) the programs recommended : ARDUINO, REPETIER HOST, ESL CAM. Yet I am unable to get the board to communicate with my pc. I have also tried to follow the V1 instructions, but they are not completely clear to me. I am using it as a router, not a 3D printer. I can control the steppers manually with the LCD screen, and it shows that an SD card is inserted, but will not show its contents. **also this may be a long shot but if someone wanted to walk and talk me thru it on the phone I would be willing to pay some money for that time/effort**

that was the first place i went. I cannot get the repetier host program to talk/connect to my cnc. My board has a usb to “printer style” cable that is connected. otherwise i do not know how else to get them to communicateApril 20, 2019 at 5:29 pm #97652

Do you have a USB-B cable, instead?
something like this:

Make sure you have one or more files with the .gcode extension on the SD card.
for example, this one:April 20, 2019 at 7:13 pm #97657
yes it is a USB type B cable. How do I get the Gcode onto the sd card, it wont let me copy and paste it.April 20, 2019 at 10:41 pm #97679
Do you have an SD Card slot on your laptop? or a SD Card Reader connected to your pc via a USB cable? If so, go to “Computer” and view the driver letter that is used for the SD Card. Then find the .gcode file on your laptop and right click it. Then select “Send to” and select the drive letter of the SD Card. Now you have the .gcode on the SD Card. Next, go to computer, right click the SD Card letter and select “Eject”. Remove the SD Card from you computer and plug it into the Rambo card (unless you have a different card).
P.S. I’m only a half step ahead of you. /TimApril 21, 2019 at 5:08 am #97686
In regards to sd card use I was having the same issues with mine. Here is what solved my problems
- SD card must be 8gb or smaller (bigger is not better in this case. I stocked up on them because it seems like the smaller capacity cards are being dropped by the manufacturers)
- G-code files must be in a sub folder of the SD card (I just have sub folders called A and OLD
- Make sure the files are being saved as .gcode
- Make sure write protect tab is in correct position on the sd card
I just drag and drop the gcode files into my sub folder A on my SD card on my computer. I also purchased a separate sd card reader for my computer (usb cord style) because the sd card slot on my computer is a PITA to deal with.
Hope this helpsApril 21, 2019 at 12:02 pm #97714
In regards to the SD card and the LCD screen. This is what it is saying. I would still much rather prefer to have a direct connection.
I have installed the arduino, so should I flash the board as the next step even though it has marlin on it?

Duff – email me with your phone # and I will call you and try to helpApril 22, 2019 at 4:42 am #97741
Is that the right firmware? I thought Ryan’s firmware had the V1 logo on the boot screen?April 22, 2019 at 6:58 am #97750
My Minirambo boots with the v1 logo and then the very first home screen says v1 on the bottom line.April 22, 2019 at 9:05 am #97758
Wow I did not even catch that, that is Marlin 1.1.5. I am not sure we ever had a version that old, if we did it was not for long. You need updated firmware for sure.April 22, 2019 at 3:58 pm #97785
Ok thats good ish-news. I have an 8gig sd card waiting on me at home and will flash the board when i get off tonight and update afterwards….Is this the version I need?? ** MPCNC_MRambo_T8_16T_LCD **April 22, 2019 at 6:46 pm #97794
no, you want the MPCNC_Rambo_T8_16T_LCD
the one you have listed is for the mini ramboApril 26, 2019 at 10:28 am #98129
OK guys, sorry for the late reply I just now had time to work on it.
I swear I had the Arduino already installed but couldn’t find the program, so I did it again and that went smoothly.
I followed the board flashing instructions and it all went well until the end steps.
#1 I had more than one option of communication ports available so I just chose the top one (3)
#2 I didn’t have the firmware “marlin.ino” file, mine was a marlin/arduino file (see pics)
#3 the instructions said not to worry about an error after finishing the upload, but I can’t help but think my error is different. (see pics)
Needless to say it still won’t communicate with the repetier and the LCD boot screen still shows 1.1.5

It should not be COM 1, at least I have never seen it be anything less than 3. Your screenshot do not show the one thing that is usually the issue, What version or arduino. Your screenshot also shows you are trying to upload a blank sketch not Marlin.April 26, 2019 at 11:24 am #98137
The arduino is 1.8.9-windows.. also I just realized that I needed to open the file INSIDE the arduino, not just on the computer. Duh that’s probably why it was blank
Just tried to correct it and this is what it looks like. Also another error
Attachments:April 26, 2019 at 11:58 am #98142
Is there more to that error?
Click on the configuration.h tab, scroll down to where is says board type. Or maybe show your control board and the file you are using you cut that off of your previous screenshot.
Also close the other arduino instance. One open at a time just in case.April 26, 2019 at 12:19 pm #98146
This is what I could come up with.

You still are not showing what files you are trying to flash, what is the folder name.
Did you install the u8glib? Show your sketch/include library drop down in arduino.April 26, 2019 at 12:33 pm #98153
Are you using the board show in the first picture?April 26, 2019 at 12:34 pm #98154
If you use that board this is wasted time, it is not made for that board at all.April 26, 2019 at 12:51 pm #98155
Yes this is the board. Yes I installed U8glib. Here is the include library Pic. I’m not understanding what you mean by the files I’m trying to flash. I am following the instructions for MPCNC_Rambo_T8_16T_LCD like Jim and you told me to do earlier in the thread.

Sorry but my files are built for very specific boards, you will need to edit the files to work with that board, if they do. Some of those only work with GRBL.April 26, 2019 at 2:57 pm #98176
Well……. Poop. Do you know where I can get instructions on how to flash it with the GRBL firmware?April 26, 2019 at 3:23 pm #98179
I just googled it, looks like it is a ramps clone. So using my Ramps (not Rambo) firmware should work.
Sorry about all the previous confusions I did not read through the whole thread each time.April 26, 2019 at 3:33 pm #98188
No worries. I appreciate the time you took to help me out get this far.
