I purchased a 3d delta printer from Flsun. Put it together but I can’t seem to connect to it and make it do anything.
I am sure there is some sort of communication issue but for the life of me I can’t figure it out.
Windows 10. The Arduino Mega 2560 is showing on COM3. But when I run the Arduino software (1.6.1) it can’t connect to the printer. Nor can the Repetier Software. All the software sees the printer, but all say they can’t make a connection.
When I plug the printer into the computer it goes beep-boop so I know my computer is seeing it and the green light is on one the printer control board.
I am sorry if you are shaking your head right now with all this newb issues, but it is very frustrating and I do need a bone tossed my way as to what the issue might be. I have played with the port communication speeds to make sure they match but still no success.
If anyone could give me a hand here, it would be most appreciated.
How does it connect? USB and if so what USB port are you using? If USB 3 try moving to a USB 2 port.I am not familiar with this one so pardon any dumb question!
I don’t know how this kit is delivered, butmaybe there is no firmware such as Marlin loaded yet? If so, that would explain why Repetier cannot connect to the printer.
As for the Arduino IDE: Perhaps you did not select the Arduino Mega 2560 board from the tools->board menu?
If you go to device management is there a device with on “!” in it? You installed the arduino driver? The usb to com driver is not standard installed in some of the win 10 editions
Brian, use the email support from FLSUN. I have also purchased a Delta from them and they provide terrific support.
Be sure to break down your connection problem, tell them step by step what you are doing, and where you expect communication, but are not getting it.
Look on the USB drive they provided at the user manual. they provide step by step instructions to creating a connection, updating the firmaware and then testing the printer. Do this STEP by STEP and don’t skip anything!
Did you try to use pronterface to test your printer / connection as per the instructions? What happens?
USB 2/ 3 wont matter at all in the communication process. The only time that would make a difference is if you are actually trying to print from the computer ( don’t do that, load you gcode to the memory card and run it locally, much better results! )
Apologies if someone has mentioned it already, but here’s my short list of todos in this case.
After running through the great suggestions above re; drivers.
1. Pick one of the available ports. Doesn’t matter, going to try them all eventually.
2. Try all the available speeds one by one. Start with the faster speeds first as they are most likely what the Mega is using. You may need to close and reopen the arduino software each time.
3. Repeat with every speed and port available.
4. After 1-3 are done. Try a new cable.
5. If needed try another arduino to confirm connection to something. I’ve received bad Mega clones that will do what you are seeing, appear but not communicate.
Follow this to the “T” and make sure you get the right Hardware driver installed for your arduino. (Then I assume you’ll have to flash Marlin or some other printer control firmware to the arduino).
