Thanks @Tinken. The Pulse was my 9th 3D printer, and have owned it for well over a year. I've spent hours on the forums looking for how to do simple tasks; to assume this is appropriate for a printer sold as a reliable machine makes no sense, and to then suggest I need to pay for a subscription to get basic functionality I though I already paid for kinda misses the plot, doesn't it?
Dragging and dropping gcode files does not work-- Nothing happens. Loading the gcode to an SD card doesn't work. I select a gcode file at the printer-- nothing happens (and yes, I export the file as explained on this form to do so). Slicing files takes 3-5 minutes, vs 5 seconds with Simplify or Cura. @LarsBrubaker The Empty Bed issue: See Here and Here. A part appears on the plate, but when I try to slice or click print, it gives an error: empty bed. Updated to the latest version and trying the suggestions in those threads made no difference. I'm not sure what 'workspace' vs 'printer bed tab' means, but if it were an intuitive UI, should I have to?
I don't have these issues with my other workflows, so I'm going to take your suggestion and use another slicer. Maybe I'll try MC again in the future when it's been decluttered and streamlined.
