If you have a combined C axis/spindle, I think the position does really need to be
reset when going back into C mode (Ideally by homing to index or absolute position)
because if you simply do math on the accumulated spindle mode position, you will
eventually lose  position resolution as the position gets huge.

The EK1828 *should* work with recent versions of LinuxCNC-Ethercat. I have one of the other EK18xx models in a test system, and I'm petty sure it works.

Hello, I have a Beckhoff module that seems to be unsupported (EK1828)
I'm struggling to make this xml file and cannot figure out how it should be.
Is it possible to debug it? (It seems like I can write error in the file and LinuxCNC still open without any failures...)

Maybe some of you could look at my xml file, I have attached that and the other config files. I have also taken a output of ethercat slaves -v and ethercat pdos (I didn't get anything with the ethercat sdos)

thank you
sorry
i learned something new for me

i call it a game pad, its a touch mouse pad, mouse click, mini keyboard. same thing i assume.

For a gamepad you may want to have a look at the 'hal_input' component. Here is a little how to for keyboard. For a gamepad you would only need to modify the keyword in the 'loadusr' command line:
forum.linuxcnc.org/38-general-linuxcnc-q...s-in-gmoccapy#309096

You can then connect the gamepad pins to gmoccapy pins in the POSTGUI_HALFILE:
linuxcnc.org/docs/html/gui/gmoccapy.html#_jog_hal_pins

That line is fine as he is setting a signal not a pin:

Yeah, I'm just using a cheap stepper drive but it does have an encoder built in so it dosent loose steps, I ran it yesterday for hours running in the gear teeth drive. And the gear engage command would do the g10 l20, so it should be accurate. I'll be testing this next week.
The bit that has me currently is converting 8.5674 etc to eight point five six seven four revolutions, and getting rid of the eight.

Certainly works for me:

with this in the [RS247NGC] section of the ini:

So i have been looking at a lot of belt drive idea's after doing this build. i have been playing around with a open ended reduction idea's and think i have something that would work and get a lot more from a smaller width belt. the down side to belts when you have some forces at play are what i believe to be minor flexing of the belt engagement into the drive pulley, belts just are not rigid like a ball screw in this respect so you either have to go to a wider belt or figure out a way to get more surface contact with the smaller belt.

Tommy i know how you do your reductions and i have looked at your designs quite a bit. The omega configuration on the open-ended side is a good way to get a few extra teeth engaged and is the basic configuration on my build minus the reduction. what i have built works mostly because the motors are oversized for the size of the machine. Keeping the design simple was a good base line to see what works and spot the tiny issues. for me it's surface finish between step downs
the idea i want to test is something like a serpentine belt reduction for open ended belts that would do away with the closed loop belt reduction on the drive shaft of the omega configuration that i see you using. my thoughts with a serpentine configuration is you end up with a lot more surface area in contact with the toothed pulley's which i would think would translate to a stiffer drive system.
I did some rough sketches to see what kind of footprint it would have and it seemed pretty compact  doing a 3 to 1 reduction with 3mm pitch belt. roughly 4.5 inched by 7.5 inches.

With standard firmware P1 is all GPIO regardless of driver settings

man hostmot2

For GPIO setup information

(GPIO starts up as inputs so pins used for outputs
must be set into output mode)

Note that the P1 pins are 5V tolerant but have 3.3V output levels
Suggest using a cheap parallel port breakout if you want buffered 5V levels

I need 5V outputs. I'll drive some low power relays using these GPIO's.

Hi...got the same result as posted above...below is pasted result...do I need to reinsert usb that had ISO?

Thanks

I have a question: I have already installed ethecat and linuxcnc-ethercat. With the command sudo systemctl status ethercat.service I see that the service is running. With the command ethercat master I try to see which master is configured and I get the error: Failed to obtain number of masters: ioctl() version magic is differing: /dev/EtherCAT0: 37, ethercat tool: 30

The question is: do I necessarily have to have a device connected that supports ETHERCAT to confirm that I have everything installed correctly, or why does this error appear and how to solve it?

sudo apt update
then
sudo apt upgrade
