Hello all, I am having a few problems with Universal Gcode Sender and was hoping someone might be able to help... UGS usually works fine for me, but occasionally I have a strange problem where I open a gcode file in UGS (v2.0 Nightly Build) and preview it using the visualiser. The model looks fine in the visualiser. I then connect to my CNC machine (Ooznest Workbee using xPro v3) and home it. If I then open the visualiser again, the model looks completely different, and does not cut correctly. I have attached two photos to show what the visualiser shows before and after connecting to the xPro v3. It is supposed to be a very basic rectangle cut in several steps of depth: Before connecting to xPro v3: After connecting to xPro v3: Does anyone have any idea what could be causing this? It appears like UGS interprets the gcode file differently after it has connected to the xPro v3. I presume when it connects, it gets some info from the machine which then causes it to interpret the gcode differently? Any help would be much appreciated.
