Hi,
i am verry new to LinuxCNC and want to build a machine. The Axis will be made with Stepperonline A6 Servos with ethercat. But i´m stuck at the ethercat configuration, as I basically dont know anything about it. All i know is that i need an .hal, .ini, .xml and .conf file. I have already installed the ethercat drivers with the guide from rodw and can set the preop/ini mode via the Ethercat slave ... command. What do i do next? I have opended and created a machine, with the axis sim preset, now with the folders in my home directory. How do i create the needed files and integrate them, so it works? I have looked through multiple topics on the forum, but cant get any wiser with them. As I said, total beginner. Any step by step help much appreciated.

Thanks.

I moved the voltage divider to the first stage and put a zener after it for overvoltage protection like Hakan.

@tommylight: Do you have a schematic you can share that shows how you use 3 resistors for voltage division. I'm having trouble visualizing your description.

Here's where I'm at right now. I need to add SPI isolation. That's going to be the biggest stage of all because there aren't any good through-hole all in one solutions like there are for SMD.

As a result, I started experimenting with Z-axis acceleration settings to reduce braking time. Previously, the acceleration was set to 2000. When I set the acceleration to 6000, no errors occurred over 14 hours of operation (115,000 measurements). When I set the acceleration to 12,000, I got an axis misalignment error. It works acceptably at an acceleration of 9,000.

As a result, www.forum.linuxcnc.org/38-general-linuxc...lock?start=30#344768

you could try a shutdown.hal file that setp's it to what you want. You may have to unlink the pin as well

Looking at your first post, its not network related. Note those previous settings do not persist. Running out of ideas. As PCW mentioned ensure the NIC interrupt is pinned to isolated core 5

You mentioned graphics so you probably have an Intel i915 GPU which hangs on my PC. Add these to grub to lock it downi915.enable_dc=0 i915.enable_fbc=0 i915.enable_psr=0 

I've got a SSR in the latching loop of my spindle contactor being controlled by one of the outputs from the 7i76
net machine-is-enabled hm2_5i25.0.7i76.0.0.output-07

Short of re-wiring, is there a way to temporarily leave that output turned ON when linuxcnc is being closed and re-started to pick up new config changes as I mess around inside the HAL and ini files setting up my new VFD and gear selection code? I can't help but think having the 220v power ripped out from the vfd over and over again isn't doing it any good

The capstain turret lathes I've seen move to a safe location - generally max X & max Z - before tool changes (Hardinge, Haas CL1) but none of those have tailstocks.

Do you have a tailstock detector in the carriage?  If so, you could make a toolchange macro conditional so you aren't right up against the tailstock, potentially swinging a long drill in to the tailstock snout.

If not, you might think about installing such a detector.

eee was already off, not sure about gro, lro or tso but I will try with them disabled also.

thanks, 6 core PC with one isolated = 5 available so that's right. i5 should be fine
What network card? is it Realtek?

I've been researching this today. Here are a few more obscure settings that may help where eno1 is the NOC name from ip a

Its an odd looking voltage plot.
I would look at the time after arc ok the THC is activated. To me it looks like it needs to be 2 seconds. I just can't see the setting I'm looking for.
Early activation could be disabled by the big fluctuations in voltage.

Use the 'Add a comment' box at the end of the 'Conversation' tab in the PR page:
github.com/LinuxCNC/linuxcnc/pull/3877

The discussion should occur on the PR. its up to the dev team, not forum users so you neet to convince the gatekeepers. Personally 80 files in one commit is too much to clearly understand and debug build errors.  Perhaps the component is in one PR and the sim in another.

No, it didn't

What aspects of Andy's carousel.comp have you identified as needing improvment, and/or what other features/funtions are you adding with this comp?

Do you have a github repository, or just keeping the current version of code uploaded to the initial post in this thread?

My Schaublin tool changer is extremely simple, with just a single input to open the tool change pneumatic valve, for a fixed duration, and then checking the next feedback pin went high. Cycling through until the target position is reached. I don't need much of the code like tool unlock, tool lock as that is all pneumatically sequenced.

I am not sure what to do about motion to a tool change position. Given the excessive size of my carousel, relative to the lathe envelope, and wide variety of tool geometries, tail stock etc I suspect it is safer to not automatically move to a tool change position. Do you have thoughts on that?
