Weird, it was my understanding that the board came from V1. Last owner was having trouble though so maybe they made changes.
I just tried to redownload it. After putting it on a microSD and putting that into the SKR I repowered it with the screen completely unplugged. Unfortunately it did not give the green flashes, there was no light changes as far as I could see
Unplug the TFT cables from the SKR Pro, and make sure that the firmware.bin file is on the root of the SD card (MicroSD for the SKR Pro)
For the TFT, it has to be connected to the SKR Pro (Or else you have to separately provide 5VDC to it) in order to flash.
I get the feeling though that you’ve got the black cable plugged in wrong, and it’s basically holding down the reset button (Shorting that pin 5 to ground)
No change. the EXP1 and 2 Cables were initially removed when it was rebooted. When that didn’t return any green flashing LEDS I repeated it with the black cables removed.
The loose connector is attached to the top of the board, closest to EXP 2 ribbon cable. I’ve tried reseating them and trying to ensure that everything was fully pressed in.
Receiving the same notifications of no printer on touch mode, and only “Marlin Mode” on marlin mode
Can you connect to the SKR using USB? Starting to sound like a dead board. Marlin mode with the V1 firmware should only require that the cables are properly connected.
Don’t worry as much about the green lights for now, one of those indicates that the firmware on this board has a fan turned on, and the other is a “heartbeat” indicator that this firmware runs, and I don’t think Marlin does.
Hi Dan, sorry for the delay. All three LEDs indicated are lit up, so I was hoping it was not the board. There is a fourth, Z1 labeled LED illuminated located where the stepper motors plug in
Ok, all 3 lit up is good news(?) But if it isn’t flashing the firmware, something isnt right.
You should try plugging in a USB cable to a computer.
It should create a serial port (if not, the board bootloader is toast) and you should be able to connect at 250000 baud. I use putty to connect, but there are many serial terminal programs that can do it. From there you should be able to query the firmware.
The LEDs next to the motors are end stop indicators. They should be on if the end stops are triggered.
All three are definitely lighting up, and another light that I did not see is lighting up now, directly to the left of the usb port. It’s plugged into a USB A to USB B cable (Link below for type), but not showing anything on Repetier host.
Touchscreen mode is still returning no printer attached, and Marlin Mode is returning “Marlin Mode”
Haha same. It’s looking like I may need to buy a new board, but I wanted to wait to see the prevailing opinion of the previous posters. The biggest thing to me is that previously the board worked, and now after just breaking down and shipping it doesn’t seem to, so it feels likely this is user error not board
Those green power adapter board do not have a good track record around here. I would verify you are actually getting full power through it. To be safe take them out of the loop for now.
Do you mean the wiring to the stepper motors as well? Or just the ribbon cables that connect to the TFT.
Was just playing with it some more, and the stepper motors are locking with power so they are definitely receiving power, though I did not verify how much. Additionally just played with the firmware more, and the bin file does not seem to be converting to a cur file, which it’s my understanding indicates a successful download
So i was never sure the previous owner was fully understanding everything being told. Hopefully they were removing power on changes. This board very well could have problems. At this time i am not much help as i do not have that board. Hopefully you got a good deal and can get a new board if necessary.
Hi Riley, yes that was absolutely a concern when we discussed price, and he did give me a good price as a result. If I need to get a new board I won’t be upset, but I am trying to keep this as budget friendly as possible. Unfortunately they don’t pay us grad students too much
