Looking for some help, please. Been using my UM2 for over 2 years with few problems. However, about a month or so ago it has started to have an issue whereby at the end of every print instead of the nozzle simply moving to rear left and platform descending the nozzle will stop at the final print position, ooze material creating a large blob and eventually (after about 20 seconds) break away from the part and park the head and platform normally. It is even doing this on gcode files that were sliced many moons ago and printed many many times with no problems. So both previous and new gcode files are doing this. Every single print and it is very annoying. I am suspecting firmware and it does not matter whether I have sliced the file using S3D or Cura, same issue.
Any ideas?
Thanks
