Hello!
I am trying to do tool length probing button script, but have some problems with mcCntlGcodeExecuteWait function. The function executes, but in the mean time Mach4 freezes and position DROs are not updating.
How to solve it?
Regards, Denis

Post the code to check, but does sound like you have an infinite loop somewhere

Hello!
This is the code (very simple):
--Measure
inst = mc.mcGetInstance()
local rc
function GCodeExecute(GCode)
local rc = mc.mcCntlGcodeExecuteWait(inst, GCode)
if rc ~= mc.MERROR_NOERROR then
return 'Error', false
else
return 'OK', true
end
end
local a, b
a, b = GCodeExecute('G0 G53 Z0 X-200 Y-300')
if b == true then
mc.mcCntlSetLastError(inst, 'test move.')
else
mc.mcCntlSetLastError(inst, a)
end
At this time I'm using simulation device for motion tests. The code is executed on button "LeftUp" event.

I have just tried to do it as Macro script and there is no problem with freezing...

Hello Denis,
i also had this problems. It looks like there is a problem ore a new behavior of the mcCntlGcodeExecuteWait() function.
Try to use mcCntlGcodeExecute() instead of mcCntlGcodeExecuteWait() when ever possible.
I used the whole day yesterday to debug an fix most of problems after update to newest mach4 version.
Now it works so far.
