Connecting to a CNC machine, pros and cons of USB vs PP vs Ethernet etc.

[Lee Roberts]

Hi,

Jazzcnc, at no point in the discussion did Jess make personal comments about or to you, in the way you have in reply to Jess, please respect other forum members, as rightly pointed out by GEOFFREY, you are a Forum Superstar , we know you for greater things ;-).

I've read this discussion from the start and suggest it's now time to move on to other things more deserving of our attention, though I can understand the points both of you are making:

Jazzcnc, I share the same thoughts as you to some extent on this, as in, who cares what is really going on "behind the scenes" so long as the machine is reliable and doing what is required, something's I picked up was that, motion control units that communicate via Ethernet are typically more costly, have a higher level of sophistication and may have the ability to "hide" any problems that may be occurring, giving the effect that everything is "fine and dandy" when actually it may not be, so some form of investigation may not be a bad idea.

Jess, I share the same views as you regarding "treating the cause, not the symptoms" and I'm exactly the type to investigate further myself before moving to a different technology, however, in some circumstances, it may be a better idea to switch to something else, a few of our members use their machines in production environments, so down time would be a major problem. Moving quickly to an Ethernet based system, to get up and running again sooner, may be the way I would choose to go first.

Thank you both for the things you've contributed so far, yet again I've learnt a little more on the CNC subject, which brings us nicely back on topic!

lateAtNight, have you implemented a solution to the problems your having, if so, what did you choose to do? if not, what are you likely to do next?
