Lag in MPG response after updating from 2.7 to 2.9

 
Hi all,

After updating my system from 2.7 to 2.9 I am experiencing a lag when changing directions with my MPG wheel. It is like there is a short period of time (maybe 1/4 second) after changing direction (e.g. +X to -X) when linuxcnc is ignoring the MPG pulses. Otherwise, everything seems to be working fine as it did before the update. Does anyone know if 2.9 has any settings that might cause (or fix) this?

The HAL file is attached. I'm following up with the pendant manufacturer as well, but it looks like they just made changes for the joint/axis separation in 2.8.

updated version LinuxCNC 2.9.3  Debian 12 Bookworm PREEMPT-RT ISO  
Vista cnc M1 USB pendant 
Atom 525MW motherboard
Mesanet 5i25 PCI board--using its parallel port

Thanks,

Rob
 

Is this just velocity jogging ? (there is an option to stop the axis when the wheel stops, even if the axis is not in position yet. ) Though I don't think that has changed.
A lot related to the names of joint and axis pins changed between 2.7 and 2.9, possibly the conversion script missed something.

I have been using individual step jogging
