slic3r goes super fast problem

Have you opened the gcode in notepad++ and converted on the G0 commands to G1? The system as it is does not recognize fast moves. Which is what G0 command is. I might have that backwards. I dont worry sbout it any more since I flashed mine to Repetier firmware and use Repetier host. But ever they are now, need to be the opposite. Notepad++ allows you to search for example G0 then replace all with whatever like G1.

If they are G1 now, then yes all the G1 entries have to be changed to G0. Depending on the size of your print this could number in the thousands and that is why you want to use notepad++ as it allows you find all of a certain search and then replace all with another entry. You will have to forgive me, last month I switched to Repetier firmware and Host so I can just throw any kind of STL at it now and print. So it has been a while since I had to convert and I cannot remember if Slicer makes them G1 or G0 by default. I just know that whatever slicer generates you have to change because the XYZ firmware does not support fast moves and that is what Slicer generates by default and there is no other way to change but to edit the gcode after slicing.
