First build, was wiring everything up for a first go at it. I updated the SKR 1.2 Pro to the latest firmware following the instructions. Then I moved onto the TFT. When I first plugged it in then powered it up. The screen was completely blank (Grey as pictured). Figured it just needed to be flashed.
I powered it all down. Put in the memory card with the latest files on it. Powered back up, and i got a very faint / washed V1 Logo once that said ‘CARD DETECTED’ or something at the the top in red letters. Perfect, figured it was doing something. It went back to grey in a second or two… Thats where i’m sort of stuck. It beeps if you press the screen or button, but nothing changes or comes up.
I pulled the SD card back out, and looked at the files. They now have CUR beside them. (pictured) So i think it updated? I can’t get it show anything, with or without the sd cards. I pulled the card out of the SKR board, and its file also has CUR on it.
When I try holding down the button it beeps at me about once per second. I probably held it down for about 10 beeps and nothing seemed to change. I’ll try holding it for 3 beeps specifically and see what that does tomorrow. Ty for the reply.
“When you unzip the file you have a .bin file. Rename to FIRMWARE.bin, and save it to the MicroSD for the SKR Pro board. Make sure to unplug both grey exp½ cables for the screen before proceeding. Insert the MicroSD back into the control board, reset, and the board will flash a few green LED’s for a second or two. The board now has new firmware (seriously that easy).”
Tried that from reading another post, didn’t seem to help. But I think it already flashed and renamed the files CUR. Maybe I will try putting some fresh firmware files on the screen and letting it work again without the grey cables.
I have only the black cable plugged in now. Tried a couple variations of with SD card, and without. Full reset and just resetting the screen with the button.
I recorded it uploaded it to google photos here:
Without the cables plugged in, i don’t get any beeps when pressing the knob down. Tried 3 second, 5 second and 10 seconds. Doesn’t seem to respond.
It almost seems like its cranking the brightness contrast up all the way or something. If you leave it for about a minute, it does dim the LED back-lighting.
Haven’t tried re-doing the firmware again yet. Might give that a go.
So I went to the BTT github and got the original fimware, and tried loading that on without he config or theme. It seemed to load on fine, i get the same 3 seconds of washed out display, then fade to grey.
I tried re-loading the V1 Firmware with all three files, it says its about 4% finished before the screen fades to grey. I left it for about 10 minutes to make sure it finished flashing.
Back to where I started. Wondering if something is wrong with the display? I didn’t edit anything in the config.ini. I’ll look through that see if there is like a contrast i can change or something?
I powered on the board, and connected to it via pronterface. All the steppers moved in their correct directions corresponding with the Extruders = 0 Dual endstop firmware. So pretty sure the SKR 1.2 PRO Mainboard is working anyways. I suppose I could go buy another r-pi and attempt to run headless/laptop… Was sort of planning on setting this up in the garage and running SD’s back and forth, I have no wifi out there… Would be annoying to try and set that up.
I have a buddy who bought the same kit, i could try swapping screens with him, but hes an hour away… not happening any time soon.
That is the first time I have seen that. I also think it looks like some kind of contrast setting. I remember there was some way to hard reset it, so settings like that would get cleared. Otherwise, I think it may be a dud.
The v1pi image has a hotspot version, so you could use cncjs or octoprint without internet, but that wouldn’t help you get the gcode to the shed.
The marlin mode is:
hold for 10s
it shows marlin mode and btt mode (but you can’t see it)
