Hi Julian,

Did some updates.

The scurve is now conversed to c code. I think this is easyer for bug solving.
And it can now be used directly in lcnc components.

I forgot to apply the feed overide to the end velocity's of segments.
Now it's running much faster.

I came accross a new bug. When a new buffer was loaded, the velocity was starting from zero when
using feed overides around 300%. Lower than that the bug was not visible.
This now is solved. During a new buffer load and transition the velocity keeps up.

There was also a endvel=0 error, wich halted motion,  is solved by pushing the motion into a new segment,
depending on rundir.

Extreme feed overides:

Hello everyone,I'm currently facing an issue while trying to write to the pinusing thecommand in my configuration. Despite the documentation indicating that this pin should be set to read-write by default, I am receiving the error message:"pin 'cia402.4.controlword' is not writable."Here are some details about my setup:

• I have verified the HAL configuration and ensured that the pin is defined correctly.
• The EtherCAT configuration appears to be set up properly, with the relevant PDO and SDO entries.
• The drive is in a state that should allow writing to the control word.

I would appreciate any insights or suggestions on how to resolve this issue. Has anyone else encountered a similar problem? Any help would be greatly appreciated!Thank you!

Thanks for the input guys. I have been able to get quite a bit of the interface working, (display alarm/state, query status of all components, get firmware revisions, set source, set process, and fire torch), but there is still a healthy chunk more to test and work out.  Unfortunately, the XPR I have been connected to has to ship out in a few days and I just came down with the flu.  I have written a python script / hal component to upload and download sdos with a back door local network socket connection to do large multi-index updates and to set things from the gui.  It seems to be working adequately, but still needs a few tweaks and more testing to make sure it is robust.

TRUE HOLE

Hypertherm has a list of features a cnc has to be capable of in order to claim it can support 'True Hole'.  The biggest hurdle is that given an ending feedrate for an arc segment around a hole, it has to be able to ramp up velocity, (the feedrate), linearly from the beginning of the arc segment to the end of the arc segment.  I don't think we have that ability with linuxcnc.

to Windows 11 or you can no longer use fusion 360.

Windows.... has been a train wreck for anyone who remotely values their privacy and/or security.
 

Hence the last version of Windows I used was Vista. Linux all the way for me.
