Ok to take it further. I am retrofitting an old superslant lathe. All axis motors hare being replaced (and drive) the drives will work either way analog or step/dir.. The spindle because of the motor size and cost to replacing I am keeping the way it is.. I have a gantry mill I built that uses (and I apologize for saying on this forum) mach3 in step/direction and tuning the driver to the motor is a nightmare unless you pay 4 times the price for the American drives with decent tuning software. So, and it hasn't been confirmed yet, if analog means that linuxcnc does the tuning, and not the driver that needs to be tuned, than this could solve a big head ache for me. But only if this is true For many years my head has been in step/direction, but I'm thinking I may be wrong in that.
Someone with more experience in both would know right off what is better over all and for what reasons.
Any thought to help me figure crap out would help.

It really depends on your existing drives.

Typically analog is used when retrofitting systems with existing analog drives
If your existing drives can do step/dir, that's usually easier to setup.

Analog drives most typically work in velocity mode and have local velocity
feedback. In this case the analog voltage is a velocity command.

When you say the analog output controls strength/force, this would typically be
called torque mode and some analog drives work in that mode, but velocity mode
is much more common.

In either case any time you have a servo motor, you may need to tune the
system for best  performance.  (simple step motor systems do not need tuning)

I have a couple questions about analog vs the step/dir formats.
First, obviously what is better for accuracy, and speed?.
Second, do you still have to tune the driver to the motor when you use analog? because I find it hard to tune the motor to the driver, and I have read a few things on here about tuning the analog system in linuxcnc and it seems doable.

The reason I ask this is because from what I am reading, in analog the linuxcnc controls the strength and force of the motor. and if that is the case, giving the tools that linuxcnc gives for that, then that may be the better way to go if what I think is true.

very nice, my only other bitch is that, encoder and position feedback are not interrupt driven but polled, this creates issues with positional accuracy at very high speeds and very high accuracy.

Thanks for the reply.

My Tool length + Z15 would be 36,24mm.
My Workpiece has a height of 6mm + mounting fixture of around 20mm
Resulting in a height of 62mm
My maximum move on Z axis is actually 205mm

Is this move relative to my current position? Say, I am at Z=0 (meaning homed at the highest point) it would try to move further up by 36mm?
If so, then a move to a "safe position" lets say 100mm would be required beforehand?

Could it be that there is an issue with my machine config? From what I learned here , it should be correct that the max_limit is 0 (?)

My machine .ini configuration for the Z Axis is as follows.

FAN2001 Its old and obsolete or close to obsolete
I could send you a few in an envelope but if they are
both damaged, more maybe damaged as well.
 

Mesa 7i96S as the first in line, all in one, then to move things along, Mesa 7i85 for encoders and Smart serials, then add 7i84 or 7i70 or 7i71 for IO as these can be remote to any place on the machine and require only a single LAN cable to communicate.
Mesa boards start at something like 70$ and up, they are very fast and very reliable and i have used a lot of those on industrial machines that are in use daily.
Anything else you look might seem cheaper, it is not, and they will be extremely limited in expansion compared to Mesa.
You can probably do this cheaper with Remora boards or ESP32, but to much fuss and messy wiring and to much time compiling/configuring stuff just to make them work.
BTW, i did test ESP32 and it works, and i can build any damn thing i need, but the time and effort is not worth at all compared to Mesa "wire it/power it/run the machine."

Sounds like something has gone wrong with the Ethernet section of the 7I96S card.
It should be repaired/replaced under warranty, Contact Mesa or your dealer for instructions
 

Ok, i fear that too. But i will hook it to this Jtag debugger thingy at work, just for curiosity

Will post if i got some insights ..-

That looks OK.
Did you use the Network Manager to set up the network?
If yes, you need to check the "use this connection for local ..... " not sure what exactly it says as i am on the phone.
That is for wired network only, IPV4 settings.
You also have a wireless network and if that connects before the Lan, it will send all trafic through wifi, if the above is not set for wired network.
 

I think i used networkmanger, but iam also able to set the ip with ifconfig 
The Ip Stack will notice 10.10.10.10 is on the same subnet  as 10.10.10.2/24, so it will allways send packets for 10.10.10.0/24 to that interface. (unless statics routes exist)  It also worked for like >1 year in this config and it still works for the lathe mesa with the same ip as the "broken" one. I also tried some other Laptop, with no luck

>>are you compiling with release or debug?

I'm just compiling with this sequence:

/tmp$> cmake -DPICO_SDK_FETCH_FROM_GIT=on ./Remora-RP2040-W5500-main
/tmp$> make

>> idk which one but people report trouble with one

Explain me better ...

Greetings,
I'm wondering,  it's it possible to connect a couple of controller boards  (like Arduino) to LinuxCNC, i.e.one for XYZ, anothe for ABC, one more for adding a turret or a double spindle..?

Why not, it seems to me there must be a way now as computers got super processing powers.

If yes, is there a specific controller board type(s) that can be connected together? Maybe several types may inter communicate with LinuxCNC and to themselves too?

Or maybe connect a number of these boards to a number of servo motors and drivers and other boards to other stepper motors and drivers?

Exactly, I am just at a beginner, trying to figure out how to make my super fancy machine., so do you think my dreams are valid, or can be true soon?
Is there some hardware that I have to buy prior to others, you know in order to plan the priorities and budget, but make sure I want to build the fancy CNC?

I'm sure there are many like me.

Thanks,,

Could it be a FAN5308MPX?

Yes it is mine, it is the old one with my full name as channel name. Plenty of stuff there also, wanted to transfer videos to new channels but there is no easy way.
My other channels just in case:
