DSC SPI fault after finishing print - 3.2 beta 1

I have just ran a print successfully but as soon as the tool was docked, DSF lost connection to the duet.

Here is an output from the raspberry pi

journalctl -u duetcontrolserver.service -f

I am running RR3 3.2 beta 1 on a duet 3 with SBC
DSF Version 3.2.0-beta1+1
DWC Version 3.2.0-beta1+2

A reboot of the system was required to recover

Just had the same thing happen again after another print

Just had the error again at the end of a print. different gcode file, no idea of the cause

Thanks for the report.

Thanks for the report.

Hmm, odd. It looks like you were running some kind of macro when it occurred. Perhaps a tool change or something else?

I'll try to work out a fix. You may want to increase BufferedPrintCodes to 48 or 64 in /opt/dsf/conf/config.json and check if that helps for now.

jay_s_uk

I'll give that a go.
And at the end of the print, it'll run tfree and that's when it dies on me.
Doesn't always happen.
