      Hi to you all,

      I'm stuck on my Y-movement. The homing works perfect, but when I want to use the control, button +10 does nothing
      -10 does the + move and going the wrong way. Flipping S0 to S1 change the direction but homing is incorrect.

      Please some help.

      Leon.

        I suspect a problem with your homing files. Please post the contents of config.g, homey.g and homeall.g. Is your Y homing switch at the max or min end of the Y axis?

          Thank you for your quick response,

          My homing switch is on the min end and here are my settings:

          regards,
          Leon

            Your config.g, homey.g and homeall.g files are all set up for a Y endstop at the max end of the axis. I suggest you use configtool to generate new ones.

                  You'll want a left hand coordinate system meaning the 0,0 origin should be at the bottom left corner. So set the minimum x and y axis length to 0 and the maximum to what ever the length of the travel is.

                  Then you choose which end the end stop is at. Does it hit the end stop on the 0 side or the maximum of travel side? That's high end or low end.

                  Then you will have to test your motor directions so that when you move positive it moves to the high end and when you move to the negative it moves to 0.

                  Then your homing files will become easy.

                    Ah thank you very much!
                    Now I understand the low and high end
                    kind regards,
                    Leon

                      No problem. It stumped me at first too. I was confused by the switch types high and low and the low and high end for the position of the end stop. Terminology overlap Isa pain sometimes.

                        Also bear in mind that you may end up with a situation where you may home to a position other than 0,0

                        If an endstop is at the high end for instance. This also means that the buttons to move the head may be a little unintuitive at first.

                          They are all at the low end. Its a Velleman K8200 or 3Drag. Everything will be fine now.
                          Thanks again.
