So, I have an m6 tool change macro that I am trying to fix before something terrible happens.
My m6 macro checks to see if the spindle is running and if it is, it commands an m5 and then a g04 to dwell for 10 seconds. The problem is it doesn't dwell after the m5. The m5 must have a pause built-in because it doesn't move right away to perform a tool change but the spindle never fully stops before heading to do a tool change. It will usually just stops before entering the forks.
Another confusing thing is when I test it in MDI, it seems to work. When performing a tool change in a g-code program, it doesn't. Am I crazy?
What is the built-in pause for accel and decel in M03 and m05?
function m6()
local inst=mc.mcGetInstance()
mc.mcCntlSetLastError(inst, 'Tool change in progress')
------ Get and compare next and current tools ------
local SelectedTool = mc.mcToolGetSelected(inst)
local CurrentTool = mc.mcToolGetCurrent(inst)
if (SelectedTool == CurrentTool) then
mc.mcCntlSetLastError(inst, "Next tool = Current tool")
mc.mcCntlGcodeExecute(inst, "G43 H"..CurrentTool) --Turn on tool length offset for current tool
do return end
end
mc.mcCntlSetLastError(inst, 'Break 0')
