I am trying to do a Lithophane with my printer and have had a few weird issues. the first time I printed it half way through the print it started printing an inch to the right our of alignment the second time. I printed it again and that time about a quarter of the way through it started printing an inch to the left. the second time i noticed it while it was printing so canceled the job and the print head then crashed into the upper right hand corner (could hear the gears trying to turn to pull it past the case). the next print i tried the bed all of a sudden was out of alignment. I did recently upgrade the firmware on the printer but I've had over a dozen successful (and failed) print since then. the issues started as soon as i tried with the g code for this print. I reloaded the g code back into the tinkerine suite and it seemed to slice it fine. So my question is can a bad slice mess with the alignment of the printer?

The STL is fairly complex, especially near speakers on the bottom left and I could see that potentially causing some issues, though not much. Keep us posted on whether or not the issue persists.

Usb is not currently connected just the SD card. I started the print again before I left for work so will see when I get home. The STL was generated through photoshop and imported into the tinkerine software. It did take longer then usual to slice but I just assumed that was due to the complexity.

STL and g code are here if you want to take a look https://1drv.ms/f/s!AgAxwYrWhIGGgelKrBSj8S80KM8pGw

The g-codes generated usually wont have the issues you mentioned unless it was a bad STL that was non-manifolded, but even then it will generally not cause out of alignment issues like you mentioned.

There is a chance that during the first print, the printer skipped a step during the print. This could have been caused by a few things such as over extrusion, which would make the hardened plastic become barriers for the nozzle to plow through. This increases resistance for the motors and could cause a shift or a skip in the movement of the machine.

We have seen a bug similar to what you described if the USB is connected to a PC while printing from the SD card. To avoid it simply unplug the USB for normal operations and only use it for firmware updates before storing it away.

so looks like the 3ed time was the charm although looks like the photo was mirrored when i exported it from photoshop. Is there any way to do 100% fill anymore I vaguely remember it being posible in the old software.

You can find the infill setting in the debug menu of the slicer:

For Lithopanes, I would do 80-90% infill rather than 100%, it will fill nicely and create a good top finish.

Excelent! Thank You both for your help.
