I am having an issue completing a burn on my ortur master 2 (15w), the first three were successful (one around 90 minutes) and now I cannot get a good run. I’ve purchased a a.b USB data cord with ferrite chokes on both end, ensured I my outlet was getting proper wattage, grounded the machine and even plugged it into a UPC standbye. I’ve also messed with the feeds, it seems to run through successfully at a 90 degree but the image leaves a shadow. I am 80% confident its something to do with the x-axis travel, either a short or something beyond my control. I cannot get it to mimic the exact pattern. I have issued for a replacement but want to know if there was something that I have missed.
