simulation mode

This seems to be related to recent changes made to allow pluggable trajectory planners and homing modules.

I wonder if this is Pi-specific? Otherwise I would have expected to hear more about it.

When did you last do a git pull? Possibly this was spotted and fixed.

Hi andypugh, thanks for reply!

Sorry to hear this. I installed version 2.9 on a RPi3 about a year ago and works fine, although a little slow. I was hopping on a RPi4 runs a little faster.

I pulled the source about 2 weeks ago.

 

There have been hundreds of changes in the last 2 weeks. Definitely worth a pull and re-build.

I'll do that.

Thanks andypugh!

Sorry Dewey, I was trying to clear a forum backlog and clearly didn't read the output carefully enough.
