Work with probe

Hi,

how does the "ERR pin processing" function work? I want to process the err contact

Try to start working with probe screen but pop out this error when try to start probe cycle. 

 

I have a minor problem with the probe screen 2.9, and your help would be greatly appreciated.

I have got the probe screen working fine, however I have this strange bug, that the Latching functionality is not working. What I mean by that is the measurement only happens in the search mode, and the following probing at lower speed is not happening. The measurement is taken during the first approach at Search speed. The same happens with the tool offset measurement.

While I was trying to debug this, I noticed that when I increase the Latch distance to, let's say, 10mm (5mm further than the XY Clearance), the probe will move to that location after the detection at Search speed, but then it will go back to the XY Clearance position at Search speed and then complete the measurement without doing the probing at Probing speed. 

I am hoping it is some silly setting I forgot to enable somewhere deep in the config file. 

Please help

I’m using the QTDragon_HD UI and Probe Basic with a 3D probe.  Hopefully this may lead you to the Ah ha moment.  All values are in inches.These are the settings I have in my .ini, .hal, and qtdragon_hd.pref files..ini file

[PROBE]
# pick basic probe or versa probe or remove for none
#USE_PROBE = versaprobe
USE_PROBE = basicprobe.hal file

#3D Probe debounce & Tool-Setter-Debounce
setp debounce.2.delay 100 #this sets the delay 100 iterations of the servo-thread
addf debounce.2 servo-thread

Thanks for this. I have added the debounce function but it didn't didn't fix the problem. I am going to keep it as it looks like a good practice.

I don't have the settings you have in the ini file. However, the probe screen I am using has a separate file, "probe_screen.pref", where it keeps the preferences. Nothing seems to be missing.

I have checked the input signal in Halshow, and I can see the signal is going ON on the first approach at search velocity, but I don't see a second signal at probing velocity. The program just concludes the measurement and uses the value from the search velocity.

I am starting to think it is some kind of bug in a macro, but if that is the case, I am sure others would experience it as well.

I am using the probe screen v2.9 from this git repository:
github.com/verser-git/probe_screen_v2.9

Here are my settings for the probe screen and a macro to measure X- position (I hope it is the correct one). Perhaps someone can spot what is wrong:

OK, I think I now understand how the macros are structured. Here is the main macro responsible for probing. I am now trying to understand it and debug it. Any help is much appreciated
