You could probably keep your home switch where it is and set a Home Off value for that axis as the travel your axis has. I am not sure how the normal procedure is for Plasma as I have never had or used one but it does seem from what you are saying all Z moves are positive.
It seems that you will either have to alter the post processor or the code it produces or as you say swap the limit so that home is at the lowest position. And without code snippet.īTW, What exactly is mentioned with those three lines of code: (I selected mm for my units, NOT inch) I have idea install another limit switch and to home down to find zero position. Sometimes it works, but sometimes, when I load another G code file, I get Soft limits warning when I start cutting, and question to proceed or not.Īctually, don't knew where to look to find problem source. I've been advised to insert snippet code: G31 Z -100 F500 and to set Soft max to 60 mm, Soft min to -50 mm and Home offset to 60 mm and Auto zero checked.
I see in generated G code the first instruction is to go UP 50 mm (my safe Z position). When I start the cut, Z axis goes up, touch the limit switch and this is the end! I home my Z axis torch carriage at the top position. I use plasma table with THC300, and SheetCam postprocessor Plasma THC300 - G31 - corner slowdown.post.
