I am aware that I was cheated by Viperplasma and should have known better to by junk but it is what it is. My problem is my computer was hit by lightening so I bout a new refurbished computer loaded with sheetcam, bobcam and mach3 licensed in my name. everything works great except the Z axis. When I hit start and the gantry moves into it's proper location and that where I'm having the issue. My Z axis wants to lift 10 inches then move down 10 inches before making the initial cut. There is not enough gear to allow for ten inches so it kicks my head off and continues to try and lift then reverses into down mode and drops the torch on the table. This is my post processor, Mach 3 plasma. can anybody look at this and tell me where it's going wrong or should I just scrap it? lol.


function OnAbout(event)
ctrl = event:GetTextCtrl()
ctrl:AppendText("Mach3 plasma post processor\n")
ctrl:AppendText("\n")
ctrl:AppendText("Generic plasma post for machines without THC\n")
ctrl:AppendText("\n")
ctrl:AppendText("Modal G-codes and coordinates\n")
ctrl:AppendText("Comments enclosed with ( and )\n")
ctrl:AppendText("M03/M05 turn the torch on/off\n")
ctrl:AppendText("Incremental IJ\n")
end


-- revision 3/2/07
-- Removed final safety move. This is now done in SheetCam

-- revision 7/10/05
-- Added new arc handling

-- revision 11/7/05
-- Moved torch to cut height when preheating
-- Added dummy spindle speed to prevent Mach2 throwing a zero spindle speed error

-- revision 9/10/04
-- Added preheat

-- revision 28/6/04
-- Replaced startx,y,z with currentx,y,z

-- created 28/5/04
-- Based on Mach2 metric.post

I don't know how to edit my post and I probably seemed rude calling viperplasma a ripoff but I was frustrated beyond belief. If anybody could please help me I sure would appreciate it. Thank you.
