I have firmware version 1.0.15 and I am getting errors. I bought my Sovol SV07 directly from the company. But it hasn’t run correctly since I got it just before Christmas.

When restarting the printer, I get “Can not update MCU ‘mcu’ config as it is shutdown - Once this underlying issue is corrected, use the “FIRMWARE\_RESTART” command to reset the firmware, reload the config, and restart the host software.”

Sometimes then I “Home All,” the printer carriage goes to the center of the bed, but when doing Z-tilt, it does not . . . and the garriage goes off the right side of the bed. I get this error: “No trigger on probe after full movement.”

When I “Home XY”, I get:

X = -16  
Y = -2  
Z = 5

When I “Home Z,” I get:

X = 83  
Y = 130  
Z = 5
