I loaded both files for version 1.05. When I tried to move the M4 the fan came on but no movement. I powered down and did the Retract extend Tension dance. Still not moving. I did notice the BL belt was loose both times, but the M4 reported it was within spec.
I then loaded the V1.04 firmware only. Did the RET dance, all belts tightened, and I could move the M4 as per usual.

Further info:
I have reloaded the latest firmware and no problems moving unless
If I do the release tension, then do the retract, extend, Tension without powering the M4 off, the Arrow keys, home key etc don’t actually move the M4, although the x & y numbers move as expected. Same thing with the earlier v1.04.1
Can someone confirm this please

Hmmm interesting! That sounds like a bug in how the state machine is handling something. For some reason it’s not telling the machine that it can move even though it is in the right state. I will look into it. Thank you for the clear description of how to replicate it
Same here - thanks ian_ab for describing it succinctly, I see the same behavior on my M4, though by now so many issues around the movements, calibration and location that lost track of whether this actually happens all the time. Feels like it might be an issue related to position tracking; After succesful calibration, I tried to run an actual simple g-code pattern, but after moving about 50cm towards the first cutting position, the tool reported ‘Position error on Top Right axis exceeded 15mm while running’, repeated several times, finally triggering an E-stop. @bar fyi.

If you go back to 1.04 does the issue go away?
Hi Bar, I have reloaded both files for V1.04 and I no longer see the problem. I did have it when I loaded V1.04.1 (I only updated the firmware with that after uploading V1.05). Also when I tried with V1.05, I noticed the BL belt was slack after tensioning. This also does not appear to happen on V1.04. In summary how I tested:
Loaded V1.04 files
Powered off the M4
Powered on the M4 & connected via Microsoft Edge
Did the RET dance.
Moved the M4 via arrow buttons & Home button
Released Tension
Did the RET dance without powering M4 off
was able to move the M4 using arrow and home buttons
