Yeah thats weird, I was thinking instead of recalling the mesh it was re-running it instead. It may still be from that but I figured the pre-sliced test files would work fine if that were the case. I’ve set up about 10 S1 Pro’s at this point and haven’t encountered that before. As someone else mentioned it may be worth looking into aftermarket 3rd party firmware options. If its not a gcode issue that leads me to think its something with the printer firmware. At work right now but let me know if you need any help and I’ll try to reply tonight.
