Does any one know if pronterface ever homes durring a build?
I only wonder as I am having trouble mounting my Y end stop and would like to design one and print it while the machine dosnt have a y end stop.
Pronterface does not send commands to the printers on its own - so unless your gcode specifies a home (G28), pronterface will not home your printer.
Ok point. Do any of the Slicers add home commands?
I think the slicers only add what is in the pre/post code sections, so you should be able to edit it to do what you want. Alternatively, you could edit the gcode itself and just search for the G28 command.
I have only ever seen home commands added by slicers in start code at the top of the file.
The best thing to do if you are worried about what commands are about to be sent to your printer is to open the gcode file in a text editor. Do a search for G28 to find any home commands. I would be surprised if you find any after the printing has started.
Ok then ill run a test cube threw slicer and search for a g28
As above just delete the g28, you won’t need to search as it’ll be in the first few dozen lines at the start.
You can disable it in slic3r under printer settings (maybe you have to be in advanced mode)
