I disagree. Grounding won't fix what is inherently a bad design. Might make
it appear less often if that indeed is the reason but it's still a bad design.
Way back in 1993, before Philips had even released the P82C250 CAN driver, I
worked on a system that had about 12 nodes on CAN bus.
I'll say what Gene said. I'd bet on a groubing issue. The schmatic has an
error, a groubd wire ismissing and also shows random crossing grounds.
Run everything back to the power supply minus post.
Also you be much better if the sheild was grounded to the controller end.
Never us a machine and

Hi John,
Thanks for your prompt and considered reply. Yes, the encoder is the
RS58-O/500EK.42KB i.e. 'K' version.
Your suggestion makes perfect sense and an ideal solution. I will order
some HCPL2631 opto isolators.
I currently have some OPI1264A opto couplers on the shelf:
Hi Pete,
Based on the photo in your link a google search brings up this:
https://uk.rs-online.com/web/p/motion-control-sensors/2914305/
and in turn this although it's not clear that the data sheet is exactly for
yours but the other sheet only states push pull without any clear voltage
levels.
Hello All,
I'm hoping someone with more electrical control experience than me may
be able to offer advice on why I am seeing occasional rogue index pulses
which are messing up my G76 cycles on larger threads.
The Halscope below shows an example of the occasional ghost index pulse
which can

I have narrowed it down to this:
If I comment out all M66 lines, on startup I get "unknown operation"
complaint about the g-code file.
If I remove those conditional statements if - elseif - endif, then it
works fine.
Yes, I did find that I had incorrectly written elseif in the
tool_change file. I
Hello!
I thought that I can remap M6 for rack tool change with subroutines,
but it turned out somewhat harder than I expected and now I have no
idea what is wrong.
In INI file I have:
