Initially I have used the computer to print and monitor the prints progress however I think the slow computer &/or the increase in data flow was slowing the print somewhere. I noticed the print head stopping momentarily during the second and third layers, leaving blobs of plastic just before if ripped the whole print off the bed. Once I had checked the sliced G-code to see if it was normal (it isn’t) I decided to save the exact same G-code to an SD-card and see if that helps….
It’s currently on 88% looking good so far.
