Just make sure those EtherCAT devices work with LinuxCNC, otherwise you might need a to do some reading and editing, and some might just not work.
I am not the one to give a definitive answer as i have no EtherCAT to play with, yet.

A solution to what?
We do not know what python script you are using, what does it do, how does it do it, etc.
Post the script here so we can have a look.

Why is probe_basic used on AMD processors only?

It is not only AMD, it runs on Intel and ARM also, just the naming has stuck as AMD64 as AMD was the first to market with a 64 bit processor back in the days.
More info would be helpful, like parallel or or Mesa or Pico setup?
70000 might still be usable to a certain point for parallel port, it should be OK for Mesa, no idea about Pico as i never used them.

Nice find, thank you.

1. i really do not think this is software/electronics but hardware
2. are the last scope signals actually at 8.33 and 8.6MHz ???
3. check spindle for proper clamping of the end mill, although chances are slim
4. use a different end mill and run the same gcode and another gcode, check results
5. while the motors are locked/enabled push on the end mill from all sides, check for deviation on one side, use something as a reference behind the end mill to see easier if there is play
6. try exporting the gcode for milling in the opposite direction, is result the same.

as for interference, from what you explain it seems you have no good grounding there, or grounding is not connected
if the above is OK, check wiring for ground loops, check if grounding is done to a single point in the cabinet, check if motor outputs from VFD and servos have ferrite beads on, if not add them.
if all that noise is still present when VFD and servos are disabled, check power supplies in use, had terrible issues with some new cheaper ones lately.

I do not have the tool change position defined. Could this be the reason?

I found that when using a tool and I mounted it with a tool length of 29.6 mm, I get the error. If I mounted it a bit longer (31.2mm) it works fine! So it seems to be an issue with the maximum height although it is far from reaching it (?). Strange.

I’ll try the definition you mentioned above and try again. I am using probe basic if this makes any difference.

Checked a few things- still need to check filddling with error limits on the servo (requires me to dredge up and set up a Windows PC by the mill- servo software doesn't play nice with WINE):

• "Differential" noise isn't quite as bad as it initially looks- yes, still awful, but mostly the noise between the A+/A- pins at the servo end is in phase. The high-frequency noise that is out of phase is well below the minimum step time (750 ns). So... awful, but I think "OK". At least seems less likely to be the problem. See picture with math in it, measured at the end of the cable right where it would connect to the motor.
• Tying the A- pin to GND (single-ended signals instead of pseudo-differential) mostly just gives different noise, similarly bad. See picture without math in it, measured at the end of the cable right where it would connect to the motor.
• The noise gets far worse when I disable the e-stop on the machine. The e-stop removes power from the spindle drive and servos, so could be either one- though disconnecting the servo power plugs individually had no impact on noise. Spindle is a DMM DYN4 with all the recommended filtering on the power inputs, but still could be a problem.
• Drive strength seems OK- the 0-5V transitions are really sharp.
• Connectors do tend to be the bane of happiness (or at least reliable signals), but they seem to check out OK. Crimps all seem good (can pull on them with no movement), soldered joints all look fine, connectors are clean, secure, and haven't been exposed to any contaminants. All signals are reading ~0.3 ohms from the end of the cable to the screw terminal on the 7i76E, which is maybe 0.1~0.2 ohms higher than I get just touching the DMM leads together. I retorqued the screw terminals, which made no difference.
• I disconnected the servo from the leadscrew and turned it by hand. It appears to be slightly bent- not enough that it's hard to turn with my fingertips poking on the coupling, but definitely goes through phases of being easier/harder to turn. Might replace that on principle since it's easy to do and "not right", but it's not obviously the issue.

Will test removing spindle power to see if that's the signal noise issue, and also see if powering the 7i76E from an isolated 5V supply impacts anything. Should've tested those before posting this, but they just occurred to me now. (also changing the motor error threshold)

Thanks all for the help, even though it's not AFAICT LinuxCNC related! Really helps to have outside eyes on problems when your head is in the weeds.

I found some other useful application techniques and reference material on the rockwell website, but hands down the best read ive ever had on the the subject and the probe section had me I hope this can help anyone having noise issues, Im thinking of building a couple cheap scopes into my next control cabinet.

I am trying to set-up a Probe_Basic configuration on my mill. I have successfully loaded Axis onto a Lenovo  M715q with a AMD a6-8570e r5 processor. I have disabled all of the extra stuff in the bios and have tried different linux adjustments like locking the RT to one specific core and I still get terrible latency reports of around 70000ns. 

Why is probe_basic used on AMD processors only?

Am I missing something? Start looking for a different computer?

I have two of these mini computers for a mill and lathe retrofit. I really like the durable form factor.

Hi,

This is for Linux Mint, it is similar in XFCE somewhere in the menus, probably in startup applications or startup ...

Danke Dir, ich muss mich damit beschäftigen, ich kapier es nicht.

Habe jetzt vorerst mal einen custom M Code gemacht, den ich an den Anfang oder ans Ende des Programms setzte, der 2 Sek. einen Schmierimpuls auslöst.

On my machine the same. Firefox and terminal open when start the system.
