Hi everyone. I'm new to LinuxCNC but I'm an engineer with a background in
software and cnc machining so I'm hoping I'll learn quickly.
I'm interested in setting up LinuxCNC to run a robot arm. From what I can
tell, the wise approach is to follow this guide
Here's a link to a very short video showing the power drawbar progress.
Press unload button and cylinder goes down first. Then wrench turned on max 1
second. Then both wrench turned off and up valve switched on to lift wrench
out of the way. Sure does move fast. Might want some rubber
Hi all,
I'd rather not share the same Ethernet connection for both the
machine-internal network and general networking (browsing the internet,
etc.). Just because this will expose components of the machine to the
rest of the network, usually without authentication or similar
protection
I think the problem is less about delays at the switch but with latency caused
by sharing the Ethernet adapter in the PC with the rest of Linux.

You can work out the delay of a cut-through switch at 100M bits per
second. Comes to a handful of microseconds. But does it matter if the
delay is always the same? It is variability that matters. We are about
talking nanoseconds.
That said, I'd not want to use a network that was also being
I was under the impression that the Mesa required dedicated Ethernet so UDP
packets wouldn't be delayed. JohnSent from my Samsung S10

Do you mean that the notebook PC has Ethernet, but it is in use, and you

I think that you could probably do something clever with U/V offsets
in the tool table.

My tool setter has a plate that's about 30mm diameter. If I need to do
something bigger than that I have to do it manually.

Is there a provision for tool setting a face mill or a tool with a different
center height than the outside diameter? Or do those have to be done manually?
I imagine the spindle orientation would also matter for most tool setters due
to the spacing of the inserts.

Sorry for the delay in replying. I missed your post. I have attached the
files. I have a Modbus front panel with a bunch of buttons. One

tools 1-100 will auto toolset. My probe is T101. Another button directly
calls the tool

I doubt it. I think that the underlying reasons why LinuxCNC does not
support USB would still apply. (ie USB is generally buffered and the
standard allows
I personally don't trust USB. It tends to block for the strangest reasons. At
least a hardwired Ethernet on the motherboard should, if listed as 1Gbps,
shouldn't have the same problems. But then inside a USB dongle much of that
buffering might be done anyway.

I might be wrong, but I'd think such a device would be resource heavy. Less
hardware means more gets done is software..
