Hi Mark,
I’ve just come across this thread: Touch Plate not working - #98 by GaryLinn
So it seems this is rather a common experience. My quick digest of the causes identified in the thread is:
- The Arduino is faulty - but if probing works under Easel, we can eliminate this.
- The jog distance is in the wrong units and so the travel is too short to contact - VTransfer requires grbl to be in mm’s, but I also think this is unlikely to be the problem and sending mm move in inches mode would cause too much travel, not too little I think?
- There is noise being generated on the probe line - unlikely if probing always works on Easel, but could be the case if the problem is actually intermittent and we’ve just been unlucky.
- The probing feedrate is too fast - but this one seems a little vague. You could certainly test this by manually entering ‘G38.2 Z-50 F1’ using the console and trying different feedrates (F values)?
Could you give 4) a go and see if a manually entered version of the command works?
Cheers,
E
