@bassco How did you configure the Smart Effector for Klipper?
I can't seem to find any info on it 
This is my current config:
[probe]
pin: PC1
z_offset: -0.1
The wiring was okay and was in working order before going Klipper, so that's not a problem.
@jay_s_uk, @Phaedrux, @Veti thanks for all the help!
After quadruple checking, it turns out that the endstops were mixed up.
Since then, everything is in working order!
@jay_s_uk Z-probe is fixed, thanks!
And believe my, I'm just as baffled... M119 reports that all the endstops are in the neutral state and when I'm going around, triggering them manually M119 reports that the endstops are triggered...

@Veti Thanks! I mean it!
@Phaedrux said in Homing issues on a Delta with Duet 2:
M574 X2 Y2 Z2 S1
Well, I've upgraded to RRF 3, had a little issue with the iap4e.bin file, bot solved it... I'm now running RRF 3.1.1, but still the grinding is there on the endstops and my z-probe has stopped producing any results... it's locked to at min stop... at least the endstops say at max stop when triggered manually...
So, z-probe broke, and the towers still want to blow off... 
I'm guessing that the z-probe pin now expects to be on the z-probe-in pin instead of e0_stp as in the RRF2...
@Veti Thanks, but I've got no idea what type of thermistor is in place... FLSUN has been making changes and documentation is scarce to say the least... at least it's a cartridge type instead of the original bare glass bead version...
Thank you for looking into this 
The config came from the online configuration tool, delta parameters came from an "old" mks_robin config file for the QQ-S.
Only the Z-probe switch has been inverted through manual editing.

Hi there!
I've recently joined the duet fanclub as an owner, and I really do like the adventure that this board has taken me on!
The patient is an FLSUN QQ-S Pro, and after getting the wiring done, work on the proper configuration has started, and of course, being a newbie, I've hit a roadblock I can't seem to get over...
The basic problem is that when homing, the endstops don't stop the tower from pushing forward and tries to keep going. Here's the twist: according to M119, all the endstops are in their proper state and when I manually trigger each endstop and M119 again, the changes are reflected. According to M119 every endstop is in working order.
I'm happy to post any and all config files if that helps!
@PCR could you share your config.json file?
@tjc2005 could you share that config with me as well?
@PeteL did you manage to get it up & running?
I'm in the same shoes, but I'm not sure where it's going wrong...
Any help would be appreciated!
