homing not working at low speed
-
hi,
I try to home with max acceleration at 500 and it work, but after I change to 800 and now it pass in front of the sensor (induction sensor) but it doesn't detect it.
But this depend of the feed rate:
F360 it fail but F400 and higher it work.M574 Endstop configuration: X: high end switch connected to pin 40.io1.in, min interval 30ms Y: none Z: noneIt is maybe the min interval how is to high ?
-
I have the same problem when I try to home all axis.. But now whatever the speed, it is always the second pass how fail (the axis continue moving even if the shitch is activated)

@dc42 hi, I found what cause the error, I think it is a software bug.
For exemple:
this work:G1 H1 X1005 F3200but this fail:
G1 H1 X1005 F360And to correct it :
G1 H1 X100 F360It is when the travel at low speed it's long that the end stop it's not detected (the machine didn't stop when it is activated).
I make some tests:
work: G1 H1 Y700 F360 fail: G1 H1 Y800 F360When the speed increase the distance can be higher before it fail:
work: G1 H1 Y800 F500 fail: G1 H1 Y900 F500 -
are you running firmware version 3.2 and have you updated the firmware on the toolboards as well?
-
See this list of limitations and check if any apply to you
https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations
specifically
Endstop switches and Z probes connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.4.

I use 3 expansion board 1XD for the 3 endstops (one on each).
For the firmware I use RC1 because I don't find an other version for the 1XD.

@Phaedrux I didn't find this web page before.
This one maybe appliy,
Stalls of expansion board motors are not yet reported and cannot be used for homing
but with this limitation:
Endstop switches and Z probes connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.4.
If I understood correctly, the expansion 1XD is made to connect motor but we cannot connect an endstop switch to them and we can connect the endstop switch to the main board when the motor is on the expansion board. So we just cannot use the expansion 1XD for motors ?
-
You can connect endstop switches to 1XD boards.
