A6 Ethercat - digital IO mapping?

Category: EtherCAT

Normally, I would connect the drive up in a hal file to linuxcnc with the cia402 composnent at this time and it would display all the pins by the name used in the XML and use halshow to play. Remember the pins need to be changed to general I/O somewhere and are probably active low so a light or relay is between the output and ground (0 volt)

Usually the I/O's have an indicator light beside them so if you enable an output it should change state.

utf-8 codec error

Category: Post Processors

Hi, have used my CNC all day then set up a new job to cut.... file won't load? Warning at bottom right of the screen says
'utf-8 codec can't decode bytes 0xb0 in position 452: invalid byte.'
Many web pages result in a search for this error... all explained in programmers gobblygook. Can anyone here tell me what - and where - to fix this
Any reason why is has suddenly appeared?
Annoyed
Thanks

Makes no sense to me, a bit like being half pregnant. But each half would need their own NIC. There are plenty of Ethercat IO modles and its easy to write the XML they need. The one that is costly with limited options (eg. Beckhoff) is an encoder for spindle.

Just a general question. Does a mixed system work? Put the basics on the Mesa card and, if needed, extend with Ethercat?

Can you power off the machine and leave only Mesa powered?

I found the following in the generic xml file from the Stepperonline site:

I tried changing sub-index 1 to bit 4, and that sent a value of '16' to the drive.
Also changed sub-index 2 to bits 4&5, resulting in two HAL pins. When I turned both of those on the drive reported "48" in the 'Enable Physical Output' field.

No output turned on.

Maybe there's some way to interpret this to figure out what the values are?

I did not try another LAN cable.
The machine and PC are grounded properly.
I dont have a DVM at the moment but as soon as I get one I will measure those.
I believe this is a software issue because even with qtplasmac not running I get the disconnected error every 45 seconds

Did you try another LAN cable?
Is the machine and the PC grounded properly?
Use a DVM and measure between Mesa 24V GND and machine case, in AC mode, while the machine is ON, post result.

Those seem like two separate issues, one remap is not doing OK and the other complaining about gcode, are you running the default "Linux CNC" gcode?

<pdoEntry idx="60FD" subIdx="2" bitLen="32" halType="complex">

does control the enable - or at least whatever that line in the object dictionary refers to.

I have no problem sending values to the drive, and can change the value by changing the bits and 'padding' in xml file.

What I don't know is which bit(s) - what value - the drive requires to turn the outputs on. As I mentioned earlier I've mapped bits 1 & 2 to both sub-index 1 and sub-index 2 and turned both 'on.' Tried the same thing for bits 16 & 17.

I guess I could just brute-force it and try ALL the 32 bits for botrh sub-indexes.
