New firmware 1.21RC4
-
I have updated the release notes to include the changed G30 behaviour.
-
Hi all,
I updated from 1.2 to 1.2.1 RC4 (direct). Updated the Duet Wifi firmware, the web server and the web control interface.
Cartesian printer.I had issues with homing ('Error: G0/G1: insufficient axes homed') and found the answer in this thread - thought I'd read through all the 1.2.1 release notes but obviously not
Anyway after adding the S2 to my G1 commands I ran a home test.
X and Y worked as expected but Z tried its damnedest to smash through my glass bed! Have I missed something or is something else wrong?

1. What are you using to home Z: a homing switch, or a Z probe?
2. What M574 command or commands do you have in config.g?

I was just looking at this - I noticed in the 'Machine Properties' interface the Z switch seems be reversed..

If they are two-wire switches then it's safer to use the normally-closed contacts (the outer two on the microswitch) and set them to active high (S1) in M574. The problem with using active low is that if the wire becomes detached, the endstop will never show as triggered. This may be what has happened.
-
In the machine properties interface I can see endstop hit = 'yes'. If I then tap the switch it turns to 'no'
So the switch is functioning as expected but it appears that during the upgrade something has reversed..?
Or am I misunderstanding something?I've literally finished a print, done this upgrade and then applied the S2 changes to G1, that's all…
-
Strange, nothing has been intentionally changed in that area. How have you wired your switches - which contacts are you using? Do you definitely have only one M574 command in config.g?
-
They're two wire switches connected to the two left pins on the duet board header (with the wifi part bottom left). Is that not right then?
Here's my entire config.g. Its pretty much straight from the configurator as I'm new to all this so not comfortable changing much yet…

Ok, so if I downgrade back to 1.2.0 everything works as expected and I can see the Endstops hit = No for all axes
Then I upgrade to 1.2.1 (rc4 or 5) and all axes show Endstops hit = yes.Should this be happening? Have I done something wrong?
EDIT: I'll move this into the RC5 discussions in case its relevant

The Machine Properties page of DWC doesn't show the correct endstop state when you use active low endstops with firmware 1.21RC5. When it says "endstop hit" it means the input is HIGH, else it means the input is low.
M119 does show the correct states.
