nema17 ha! this is a 300lb machine, nema17 wont be moving it.

200w ac servo is fine for the z. I wouldn't go smaller power. A nema23 stepper would work, it would just be very slow, probably not getting past 1000rpm before the torque falls off too much.

Been using LinuxCNC for years without problem. Now, Linuxcnc loads but xcarve gives and error. Last line before load stops says it can't find network card. Is it referring to my wifi card or my mesa card? Don't know why it would need a network card.

Of course you can. Plenty of ethercat stepper drivers out there. even 2,3 and 4 motor controls in the single driver...



links to the multi kits with ethercat?

The only hitch on servo choice is there's only 100mm room for the Z motor. A 200w modern servo with a brake fits. a lot of others will be too long.

Rtelligent and Leadshine have ethercat dual motor stepper drives. example www.rtelligentglobal.com/ethercat-stepper-drive/  and www.leadshine.com/product/2EM3E-522-14-15-990-69.html
If space is an issue, there is always NEMA 17! there are 3 and 4 motor options I've seen recently but may not have been ethercat

I've spent quite a few weeks working on this, with no input from anyone, no one bothering to lend a hand (testing when I gave links and requested some one to test), and when an issue does come up all I get " I installed probe basic and tried to run it, but it gives an error." with no description of the error.

Can you understand why I may be a little bit terse. If you can't be bothered to give any indication of what the error is or anything like that I'm not going to waster time trying to pull information out of you bit by bit.

I'm not even sure that the probe basic/qtpyvcp team even support distributions for the Pi. They never used to.

no but a script could copy new versions from git releases to the existing LinuxCNC Deb repository

I meant deb repo.

I am confused !

I use a lot of software from GitHub, namely the appimage stuff like FreeCAD, OrcaSlicer, OpenRGB, OBS-Studio, LosslessCut, LMMS, even Inkscape sometimes, and this has nothing to do with the above, but a few years back i did try to do a LinuxCNC appimage, it did not go well, so i gave up.
Yes i am aware it would not work for machine control unless the RT kernel is active on the system, but i was content with sim only back then. Given the amount of wasted time, building from sources is a breeze.
On the other side of the same coin, whenever a new version of Linux Mint came up, the first thing i did was download all deb versions from buildbot and try installing them, i do try version from all distros, new and old, usually does not work, but with some other Linux distros it did work like Ubuntu something or another that worked with (what was before BookWorm?) debs.
Moral of the story: build from sources, remaster the ISO, move on!
This is a huge timesaver as i have most of the machines using Mint 19.3, so any drive failure takes about 10 to 30 minutes to fix. One of those thing that are rarely needed, but very nice to have.

A lot of stuff does work well on FreeBSD, if unreliably.

What always makes me mad is that most software available on "all platforms" isn't available for FreeBSD, or any other BSD for that matter.

In what sense is something available for "All Platforms" if FreeBSD is not supported?

Latency has nothing to do with speed.
linuxcnc.org/docs/html/install/latency-test.html


You're the one that made the claims, yet you've done no testing nor do know understand the concept of latency. There seems to be a disconnect between what you actually know and what you think you know. The thing is you don't get it. I don't think you ever will, it would be some much better if you just fucked off and stopped wasting peoples time of the forum by having to clear up the bullshit you post.

You are forgetting one thing. Linuxcnc is based on Linux and depends on the Linux preempt_rt kernel to provide a real time thread (the servo thread).  To use a different OS like  BSD or RTEMS, you will need to rebuild a large amount of the Linuxcnc application not to mention the huge number of dependencies that are prerequisites.
