I’ve been using my Snapmaker for a week, and it’s worked well for the prints I’ve tried. During the last one, the touchscreen went blank about 1 hr into a 1.5 hr print. It didn’t show “Tap screen to activate” like it usually does, it was just blank, with a small glow (reddish-black) showing it was powered but otherwise blank (no white screen, nothing displayed). Tapping did nothing. The print finished fine. I cycled power with no change. I tried with or without the USB drive plugged in - no change. I downloaded the latest firmware “Snapmaker-GD32Base-2.4” and put it on the USB drive and followed the firmware update instructions. The LED blinks occurred as expected (slow, then off, then fast) and so it seems like the latest firmware is installed. But the touch screen is still blank. There is a general glow showing it has power, but no image, no white screen like some of the forum posts, just the general dark-reddish glow, so no display, just power. I tried unplugging the touchscreen and plugging it back in again to make sure it’s plugged all the way in. No change.
I’ve emailed firstname.lastname@example.org and am waiting for a reply.
What can I do without the touchscreen? Can I use the computer connection to do everything the touch screen does? I haven’t tried yet. Reading the manual and forum posts, I gather I can run prints with the computer connection. Can I level the bed and/or change the filament and/or jog the stages without the touchscreen? I see some manual commands over the serial connection in some posts. Is there a list compiled somewhere and do they include the bed leveling functions? My bed seems to be staying level so it’s probably not a big deal, so probably just figuring out how to jog the stages + change the filament is all I need while waiting for technical support and possible touchscreen replacement.
