I’ve had my printer for several months, and have very happily printed 100+ objects with it, mostly D&D minis, with great results. Unfortunately a few nights ago the printer started behaving oddly, and now it seems it won’t boot up. Pardon the length of this, I’m just trying to include everything that might be helpful to debug this.
After a long series of good prints, I had a bad print, with the cured resin remaining attached to the bottom of the tray rather than the platform. The strange thing was that the pattern of the cured resin was nothing like the model I was trying to print, it was in short strips spread out over a wide area of the tray, rather than in the spot where the model should have printed.
I removed the tray and cleaned and strained the resin, and tried again, with the same result.
I tried printing the P_yuan-test.gcode, but the patterns it showed on the paper were nothing like normal, the laser moved in a couple of tight circles, and then stopped showing at all. When I ran this test after I first built the printer, the laser kept running over and over the same circle, but here it ran for 5-10 seconds and then stopped showing.
I then turned the printer off, reformatted the SD card (FAT32), and restored the various gcode files, but when I put the card back in and turned the printer on, the screen didn’t light up and the z-axis didn’t move as it normally does when the printer is powered on.
I see green lights on the two motor control boards, and when the printer is first turned on the mirror kind of flicks into a different position, but there’s otherwise no response.
I’m running the 1.18 firmware, with the new recommended settings, and have successfully printed several dozen objects since I did the firmware upgrade, so I wouldn’t think it’s related to that. I tried putting the 1.18 firmware on the SD card and booting with that to see if re-flashing the firmware would fix it, but 10-15 minutes after powering on, there was still no change, screen is black.
I don’t see any burned out components, and I’ve wiggled and re-seated all the cables. Powering off for several minutes to an hour doesn’t change anything, including fully unplugging the power.
Help! I adore this thing, so I’ll do anything I can to fix it.
This shows the green motor control lights:
I have a couple of other images, but I can only post one since I’m a new user.
And this is a video showing the mirror flicking: I turned the printer on and off 3 times, and you can see the mirror flicking each time.
Any help is appreciated!
