I tried lowering the S value from S5 to S1 in increments of 1 and these seemed to make the issue more apparent each time, so i then adjusted upwards settling on a value of S8 which so far after testing the home position roughly 30x seems to provide a good solid repeatable homing position, I’m super happy with it now!
Thankyou for you’re replies, I really appreciate the help
Thanks

Hi guys
Having a small issue with my E3D Toolchanger running duet 2 wifi, the sensor-less homing for the X-Axis is a little bit temperamental
Sometimes I have to home the X-Axis 4 or 5 times to get a good homing on the X, it will home every time but sometimes it will do it and the home sound is more of a bang than a subtle homing noise, when it’s a louder bang the homing position is slightly off which becomes apparent when changing tools
With my super limited knowledge of sensor-less homing it takes the resistance detected as a home position, is it possible to tune this value to make the sensor-less homing a little more sensitive?
It performs great on all other axis where present too
Thanks
Tom
@t3p3tony Thanks for the speedy reply I really appreciate it, I’ve sent the email with forum link as requested, many thanks, Tom
Hi Guys
I’ve reached out to E3D regards to an issue I’m having with the duet 2 that’s running the Toolchanger
A few days ago T0 stopped extruding filament and the motor of the extruder is just clicking, see video attached
Video: https://1drv.ms/v/s!AkVkL63GMSEogbFICoNqWHNzCyYeZQ
At first we thought faulty extruder motor, we swapped it out but the issue of the clicking motor continued with the new motor, I then wired the old motor to T3 and the old motor functioned correctly, so I then took a working tool T3 and inserted the wiring into the board as if it was T0 and it’s clicks too so I think there is a fault on the board with the motor connector for T0
Any advice would be greatly received
Thanks
Tom
@dc42 thankyou so much for the fast reply, much appreciated, I’ll forward this post to E3D 
Hi guys,
I’m currently using an E3D toolchanger that has the Duex5 expansion board, since I’ve built and commissioned the printer I had an issue from that point with T3 part cooling, it doesn’t work, I have done all the usual tracing to find the issue, first I replaced the fan for a known working one, issue remained, I then Transferred all electronic components for T3 to T2 to verify the components work correctly, they did, so I then presumed it could be off within the firmware, but again config has the correct fan selected and there is no firmware issue, so now to inspect the expansion board, straight away I noticed the actual connector on the board for T3 part cooling seems loose compared to others, so I plugged in the fan, turned it to what would be 100% and then if I wiggle the connector on the board very slightly I can make the fan blip for a few seconds but any slight movement and the fan turns off again, I have also verified this same behaviour with other fans too so I believe there is some issue with the connector on the board, I reached out to E3D to explain the above and they suggested I post here for confirmation from duet before been eligible to fill out the warranty form for a replacement board, I’d also like to add that this is my first duet3D experience and I have to say I’ve totally fallen in love with the capabilities that duet brings to the table, thanks in advance
Tom
