Firmware i3 pro C black white board

[skipperhvac]

I received my printer last week, I finished building on Saturday. Tested a print of test block.
Had some trouble, will not feed filament, tested the stepper motors on x axis terminal and they work.
I switched stepper drivers, and still did not work.
Then following your information used Arduino and Marlin to try to update Firmware.
Now nothing works.
Please send me firmware for my machine. BLACK PRO C DUAL GT2560 white board REV A, if you have a hex file that would be great, can upload with CURA software, but please send all files you have for my machine.
I will then test run again.
Also thermister connectors do not fit board, and fall out easy.

hi Bob,the firmware for PRO C DUAL GT2560 is in the attachment.

I installed the firmware and now have all my options on the LCD back , but my extruders still are not running. It seems I've tried everything.
As said in my first post the Extruder Steppers and the driver boards are working when switched to the other axis on the board.
What do I do now?

I would also like to say that I have heated the heads to 185/220c while testing.
The firmware went in great, but still no feed either motors. Have tried many different stl files.
This is my second printer, so I do have experience using them. and am proficient at soldering and basic electronics.
I really think the problem is in the main board GT2560.
I was able to start the first print, then the filament stopped feeding. I feel I checked everything possible and need a new board.
Please help, I really dont want to wait several days of messages, only to find out I need parts..I realize that you are just going to work, when I am going to sleep, and that causes delays of another day every time we message, so if you have any ideas, please list them all.
Thanks.
Bob

1.please touch the extruder head to ensure that it was heated to 180.if not,maybe the extruder thermistor is good.
2.please check the stepper motor & cable & driver board.
3.if the above solutions don't work,please contact the customer service or leave the order number.

Hi, I have exactly the same problem, any solutions so far?

Same printer, same board, also dual extruder.

Yes I have found that if I go to Control on the LCD and scroll down to Reset failsafe my extruders will work, However I am finding that I have to do that everytime I turn off then back on.
