XL five head, I just upgraded a firmware to 6.4
Now I get an alarm warning the G code isn’t fully compatible code not slice for input shaping
I cannot find an old version of the firmware, on the website, with my PC. I can view an old version of the firmware on my iPad. But I can’t get it to my PC to put it on a flash drive to try to upload it.
