To load a config you basically execute a command line command. So you could have different Icons on your desktop for all the different setups.
The mesa board does not need to be reprogrammed as you can change things around in HAL.
I have machines with several different configurations (eg vertical milling, horizontal milling, turning, milling with slanted spindle).

Thinkcentre tinys (m73, m93, m710q ....) working great. They have Intel nics.
But also Fujitsu Esprimos working great with Realtek nics. To be honest we encounters over the past year, that realtek working a lot faster. Also pci realtek boards working damn good.
But yes, historically there were problems with realtek nics, so one can have problems. But I personally looking nowadays for realtek instead of intel, but I know what I have to look for.

For a beginner I would say a Lenovo Thinkcentre tiny (maybe with wlan on board) is a really good machie. Look for m73 or m93 with 8GB and ssd and you will be happy. Isolcpus needed! and of course the lines for the intel nic. Other than that no need for tweaking when speaking of 1kHz thread.

There is actually a good MPG example in the docs with xyz axis and scale selection. It uses parallel port pins but it works on any platform.

Why not use an Ethercat VFD like the Omron MX2 which is supported in the hal driver. I believe internally its a cia402 device since it's essentially a speed control for a motor just like a servo!

Currently, I have switched to the Codesys platform, and everything is functioning normally. It is similar to TwinCAT.

Buildbot2 is correct, you need to sign it though, as per the instructions on the page:

buildbot2.highlab.com/

What I meant of course was

s12000 m3
 

Thanks langdons, that would be the last step if others fails. There are a lot of things i would have to setup again, such as wireless Handwheel, Probe basic, the TooTall18T probing routine and others that work fine at the moment, so I am a little afraid that i get more problems as today. I'm not a coder and not very familiar with all that stuff.

Thanks PCW, I will try that tomorrow and give you feedback.
This file works and let the spindle turn:
M03 S6000 G04 P120
S12000 G04 P120
S18000 G04 P120
S22000 G04 P120
M05
M30

Kind regards!

So you are saying that if you enter:

s12000 m3

 (in the MDI tab)

That spindle.0.on remains false?
 

Thanks, just the info I needed.

I'd trust your judgement.

It's amazing how often intuition is spot-on.

Maybe try making a new quick-and-dirty config?

When my CNC wasn't working quite right, I made a new, identical config with stepconf.

It fixed it.

Yes, the 7I92XX replaces the parallel port interface.

A 7I92TF will work with the same parallel port cable you currently use.
(male-male IEEE1284 type) so you should not need any additional cables.
A 7I92TM will plug directly into a G540, but that's quite awkward mechanically.

As far as the kernel goes that's included in the LinuxCNC 2.9.4 ISO, so installing
that ISO will install a preempt-RT kernel. (The 7I92 requires a Preempt-RT kernel)

As far as Mini-PCs go, it's better to use one with Intel Ethernet hardware,
as the common Realtek Ethernet chips often have realtime issues.

I have confirmed, there is a focus issue. I need to click G54 or ABS or similar to move focus before the space bar works. That caused one slightly panicky moment when I hit it and nothing happened. (Fortunately, the code was right so it was fine, I just got scared for a moment.) Is there a way to set focus on cycle start or eliminate the need to move focus?

Doesn’t work. Says “does not have release file”

Hi,
I have a Sherline 5400 CNC that has been in storage and I am planning on getting it up and running again (it's been some years).  I am computer shopping and weighing options and looking into what has changed.  My previous setup was a PC Tower with a Parallel port running to a Gecko 540.  Instead of replacing that setup in-kind, I am looking into using a small form factor (or mini) computer with a MESA ethernet card.  Am I understanding things correctly that I can use a small/mini computer with ethernet, run it to a MESA 7i92TF, which in turn runs to my Gecko 540 (thereby skipping a PCIe parallel port card)?  Also do I need to worry about male/female couplings for the MESA DB25 (7i92TF vs 7i92TM) or can it be managed with gender changers (not ideal) or are there signal considerations with gender changers?  Finally, to confirm, I should be using the preempt-RT kernel if I am going to use MESA ethernet?
 
I have been reading here and the docs, but I am still a little overwhelmed playing catchup and appreciate any guidance before I purchase a PC and MESA Card.

Thanks,
Tom
