I'm using a dedicated 24v switching power supply which is holding a constant 24.1 output. Setting the sserial_port_0=20xxxxxx and reading the fieldvoltage I'm seeing a constantly fluctuating value from 22.01 - 23.9 v

Thank you, and this is what I love about LinuxCNC, it seems that whatever somewhat custom idea you dream up LinuxCNC has the handle to make it happen. It's a tinkerer's  candy store.

Hello,
can someone explain to me why I'm getting this error message:

Linear movement in line xx would exceed the positive stop of the Z axis.

Line xx contains "N330 G53 G0 Z0." This error message isn't always possible?
As far as I understand, the Z0 position can always be reached, since it's at the very top.

Thanks for your help.

wow, great answer thank you. i was close in my thoughts, since there is no cpu and in rio.c you compile riocomp i thought that there must be something like fixed data frame structure adjusted for each config, but you made it very clear.
do you do anything about noise? like CRC (checksum) maybe for each frame in case it gets corrupted?

So I tried to upload the firmware and I have somehow broken the 5i25t as it no longer is recognized by the computer. is this something I can flash an eprom with a programmer?
