hi
in my last test there was no following error on gcode running, the problem was the very low acceleration.
following errors appears on homing procedure

cia402 defines pins to set velocity and acceleration while homing. 0x6099 and 0x609a

Hi,

Can we test the cia-402 and shortcut linuxcnc pos-cmd to pos-feedback so
there is no ferror in linuxcnc that can trigger a motion stop? 
Or test it by hooking the cia-402 to a stepgen or pid without closed loop feedback. 
 

The only time this is necessary is during internal homing (if used). During homing, motion is happening that Linuxcnc does not know about so it generates a following error if this is not done.
In the drive, motion is measured in encoder pulses and in Linuxcnc uses device units
One of the other  things the cia402 component does is scale the encoder pulses to Linuxcnc device units (mm or inch)

It depends on the drive but many of them will have a SDO that tells the drive to use open loop or closed loop. There are some reasonably cost effective open loop Ethercat cia402 drives from Rtelligent and Leadshine. Both offer drives that can control two open loop stepper motors. The Rtelligent ECR60X2A is USD $60 each ex works (for 2 steppers). 

motor is 7.5kw so it has enough power machine is heavy 3tons knee mill
and gears are strong enough..
If something breaks will be the tap.

Looks like the board is at .10 and the PC should be .11

Can these settings pushed to master?
because with default configuration i have also the same problem...

hi there,

share photos of electronic which you have...

I have build profibus machine over ethercat and it works in the 2ms synchro ... I can help you if there will be avaible stuff and time

AX5xxx from beckhoff is SoE and it can be pain to create custom .xml which should be editable out of Sachas own .xml files...

I can recommend you ethercat stuff ... S120 over drivecliq is very powerfull tool with 31.25us bus cycle but prices are out of any small shop budget ..

regards

Yes Cakeslob it's for my mill. Bought a cheap 24" touchscreen from Amazon and got carried away testing it lol Static IP address, is it 10.10.10.10 or 10.10.10.11  for the board ?

murphy, is this a new linuxcnc and remora install?

I'm trying to upload the config on another EC500 but I'm getting this error. It's bookworm installed from the linuxcnc iso on a PC.

hi

edit
testing now in axis tab manual controll it disable the drivers, i can only run when in MDI tab
Controll word in all drivers is
15 before hit start
Then all goes 6 and then 4 very quickly
 

Guys, can anyone tell me why the id.ngc and od.ngc macros don't work (nothing happens and there are no errors). The other macros taper-od.ngc and g76diam.ngc and sphere work fine? What could it be?

The motor type doesn't matter, it just needs to be supported by the drive.
The drive needs to be EtherCat compatible or you will need an EtherCat
-> step/dir interface.

The problem is that the 'on_counts_value_changed' function uses the 'value' (encoder counts) as an absolute value (as you said), but you could use it as a relative value.

if new value is higher then the last value, then move up 10% higher then the current rate.
if new value is less then the last value then move down 10% from the current rate

The current rate you can get from STATUS or from the appropriate widget.
I'm sure there will be some minor details to adjust to.

Hello everyone, 
This my first post, I am a DIY hobbyist I am trying to learn what hardware is being used for a diy CNC mills. I ran across different system and setups but I have been unable to get a clear understanding on stepper motors being used in a diy home type CNC mill for a EtherCat setup.I have poked around and searched youtube but still have not got a clear knowledge, my question is can a Nema 23 closed loop stepper motors with encoder be used in a EtherCat setup or dose the stepper have to be EtherCat designated style motor.
I have some 23HS30-5004D-E1000 motors I was going to try and play with and see if I can learn a Ethercat system
