@dc42 Oh thats clever, just what i was looking for. Thanks 🙂

@Phaedrux Upgrade to 3.2 solved it! Thanks 🙂

Increased current for the motors and that solved it! Thanks 🙂

@brasse I'd suspect the wiring; it sounds like something is 'floating', or perhaps the filament is not pushing the switch down fully. Though could be a similar issue as in this thread (similar hardware) https://forum.duet3d.com/topic/14014/openbuilds-limit-switch-reads-hit-in-s1-and-s0

For connecting it up (and do check the wiring), see https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Makerbot_Mechanical_Endstop_v1_Num_2

Edit: from the above page:

These devices produce an active-low output. If using RepRapFirmware 1.x or 2.x, use the S0 parameter in your M574 command

I think you need to invert the switch logic. The above is for M574, which defines endstops. With M591 you invert by sending P2, so in RRF3 I think your command should be :
M591 D0 P2 C"e0_stop" S1 ; filament monitor connected to E0_stop

@pipersw That did the trick 🙂 "e3heat" instead of "exp.8" was the main problem. Thanks!

G31 must come after M558

@zecchi Thanks for input, will try to generate a new config 🙂
