Hi,
I have a Flashforge Creator Pro that has stopped working. During a simple print i came to check on the progress and it had frozen part way through, the nozzle and bed were cool, the lights and fan were still on, the LCD and buttons were lit but the screen was not showing anything.
I’ve switched it on and off again and it returns to the same state, lights and the fan come on and it makes a brief beep but there is no way to control it and nothing is shown on the LCD screen although the back-light is on. I have checked the SD card in my laptop and it seems fine.
Do you have any idea what may be wrong and how I can fix it. Thank you!
I had a similar issue with mine and it turned out to be that the ribbon cable going from the main board to the LCD/SDCard was loose and not fully making contact. On mine, it started off with random SD Card errors and then eventually started stopping mid print exactly as you described.
Shut everything off. Flip it on its side. Open the electronics bay and try pushing the ribbon cable connector down firmly onto the main board. And hopefully that will solve it for you…
It may have been the thermocouple or nozzle heater elements. If it can’t read the temperatures it may fail the print. Also anything power related may have cause a reboot. Loose power cord or switch. Do a preheat and whatch the temp. If you see a NC it maybe the problem. You can replace the whole print head if you don’t want to take it all apart. Then you can slowly rebuild it and have a spare.
This seemed like a plausible issue and cause of the problem. Just gave this a try and unfortunately hasn’t changed anything, is there anything else you could suggest?
Thanks!
When I turn on the machine I’m unable to control anything with the LCD screen and buttons, so there’s no chance of preheating. Is there anything else you could suggest?
Well, if it’s not something simple like a loose connector somewhere (like the case was with mine where the SDCard/LCD Cable was only half plugged in), assuming you’ve checked every single connection point on the main board, then the next logical thing to check is all of the power supply voltages to make sure everything has adequate power, as a flaky supply or a short somewhere could cause such weird issues.
Use a volt meter and measure the 24V, 5V, and 3.3V supply lines on the main board. Bad voltages usually means something is shorted rather than a bad regulator chip, as regulator chips tend to be fairly robust. Check the temperature of the regulators on the board and see if anything feels hot to the touch that might indicate a short somewhere. If you’ve just turned the power on, everything should still be cool to the touch, as shorts tend to heat things up very quickly.
If all of that seems good, you can next try reflashing the firmware on the main board just in case something happened and corrupted it. If all of that fails to resolve it, about all that’s left is to replace the main board itself.
