      Hi guys,

      Weird one that I am hoping some experts can weigh in on.

      Long story short - I am testing some composite materials that are proving difficult when the nozzle changes direction (think a square cube, each layer, at the corners, it is pulling the composite towards the centre).

      I think I can get some success if the print was to slow down at the corners, is there any way I can change the G-Code (rather than editing each line manually) to slow down when approaching corner moves?

      Hope that makes sense!
      Thanks,
      Callum

        I think you're describing jerk.

          Ahhh of course! Thanks mate - I didn't even think to edit in the config.

          I'll try it out and see how it goes.

            OK so I have slowed instantaneous speed down to 12 mm/min from 100 mm/min in the config but don't seem to be getting any real change when running the print.
            Is there an override somewhere I might be missing?

              Some slicers can set the jerk value in the sliced gcode, so check your sliced gcode to see what's actually being executed.

              You can also send M566 by itself in the gcode console during a print to see what the value is actually set to to check if it's been changed from what you have in config.g

              There's also acceleration to consider.

              Can you post your config file?
