I have read many post about probing with the pokeys57cnc and can't seem to get probing working correct
I have tried with and without a +5 pullup resistor with the same results mach4's led shows the probe being triggered
but I always get the error message no contract with probe..

any suggestions

i use it without any problem
which "no contact " you get ? the first one in high speed or the second one?

both fast and slow

Get error message  ERROR no contact with probe in the mach4 probe screen
and in the touch module I get can't transition from MDI probing to stop

in both touch and mach4 screen the axis led is moving and stops when probe is triggered then I get the errors and mach4 enable is triggered off

If I enter a g31 z5 f10 in the MDI the axis led moves and stops when probe triggered and I don't get any errors and mach4 stays enabled

also tried a Schmitt trigger but on difference

Thanks

update if I touch the probe for a longer time I don't get the error

but the touch module gives me a lua error
 Y axis is performing a touch move.Y Axis Offset Set to: -0.616.RetractingTouch is finished. Y axis set to -0.616Lua: Error while running chunk
C:\Mach4Hobby/Modules/mcTouchOff.lua:1178: attempt to compare nil with number

   C:\Mach4Hobby/Modules/mcTouchOff.lua:912: in function <C:\Mach4Hobby/Modules/mcTouchOff.lua:911>

I haven't messed with the module so not sure why I am getting the error
it seems to have completed the probing and errored on update or something

please send me the M function you use for probe ,i can look maybe can see something wrong

I wasn't using any Mcodes I used the mach4  button on the main screen for Touch probing

Hi,

please send me the M function you use for probe ,i can look maybe can see something wrong

Probing is a function that is best done in realtime and is therefor done within the controller. Any Lua script will have
such a communication delay to make probing inaccurate.

Have a look in Docs/Mach4CoreAPI.chm/Plugin Development/Probing for a description of the sequence of events between
Mach and the controller during a G31 probe move.

I use lua with G31,and i got very good results( for me +- 0.05 its too much)

Hi,

I use lua with G31,and

G31 is largely enacted by the controller, Mach/Lua just sets the environment for the G31, the controller does all the tricky stuff.

Have you read the article I directed you to?

Not yet ,but i will,now i have problem with small movment ,like s15 mm radius circle,that mach use same speed as large movment ,and i get brake resistor alarm
