Y stepping gone wrong

  • 3D Printer Model: Tevo Tarantula / Marlin
  • Slicer: Cura
  • Hardware Setup:PC using Repiter Server, USB cable, Tevo Tarantula running Marlin
  • Problem description: I have been printing with this machine for four/five years with no problems, but yesterday, after succesfully printing one object,

I cleared the bed, re heated the bed and nozzel and re started the same G code as I had just used, and this happened!

Instead of printing each layer on top of the previous, it is stepping them (backwards)

  • What I tried: I have checked for slipping belts and runner problems and there does not seem to be any mechanical problems. I have re booted the printer and the PC

Any help would be apreciated.
