Physical Home Button Error

[maciassimon]

I have assigned a "home" button in the Masso Entries list. It works very well!
But when I press it without having released one of the E-Stops, the machine is going down on Z axis !
It does not happen when I press the soft button, or when an E-stop has been pressed / released at startup...
This is an inadmissible mistake in terms of safety, because the machine can move with a pressed E-stop!
Thank you for doing the necessary to make masso a little safer !

we will look into this and see if there is an issue.

For safety please note that you must wire your axis and spindle motor drives enable signals via the estop as you can't just reply on software to switch off these in an event of emergency. All drives MUST get disabled through the estop button.



Whats your controller serial number please?

@maciassimon we have found the bug and have fixed it, this will be released in the next software update, if you need a pre-release copy of the update then please provide your serial number and we will email you the software.



Thanks for pointing the bug.

Is this the latest version firmware? I have a physical home and E-stop and certainly don't get any Axis movement which I press home with E-stop engaged... It just ignores mine. I do have the PREVIOUS firmware still though so could be a bug in new firmware. Masso support is right, the E-stop should be a physical disconnect from drive power or disconnection of signal to the drive to be sure it halts instantly

we found that this has been in all earlier versions, in some combinations it would not affect but there was a bug.

Did you squash it in the latest firmware? that's a strange bug!
