Extruder lag is back "sometimes"

Re: Extruder drive lag with toolboard
I noticed that extruder lag is back on toolboard, but I can't find any definitive way of reproducing it. When lag occurs, extruder moves are a few seconds late.

Need more information, in particular:
- What firmware versions are you using?
- Are you using DAA (M593) ?

@dc42 Version 3.2. For dynamic acceleration I had it enabled. I disabled it when trying to create a reproduction of the issue and it is now disabled. I printed something this morning were the issue did not show up. I think I had the issue when it was disabled, but I a not sure, it is sometimes hard to tell if the issue is here or not, as the delay can be subtle. When there is a 5 second delay, it is easy to hear the extruder retraction way to late but when it is less, I only notice it when I see blobs on the print.

There is a known issue with using DAA with extruders on expansion and tool boards. It is fixed in the unofficial 3.3beta firmware, and in the 3.2.1 firmware candidate which I hope to make available for community testing shortly.

PS - RRF 3.2.1 is now available for community testing, see https://forum.duet3d.com/topic/21446/candidate-3-2-1-firmware-binaries-available.
