[pinoy-cnc]

hi,

i would like to ask for help to solve this if someone in this forum encounter this kind of problem.

the problem is when my motor drive dragger the alarm signal (means The signal goes high) but the state did not change.

i also test on my new arrive G3 Controller but this new G3 goes well without problem.

please see video

I saw your video on YouTube and wondered if you have found a solution to this problem. I disabled my motor alarm input for now but plan to implement it very soon. The only information I could find in the documentation was a reference to it in the inputs list and a couple of wiring examples. From experience, I know that not all external outputs are compatible with Masso TTL logic as Masso relates the input signal to its own power supply source.

Do you have a diagram showing how you connected everything?

How is the Alarm output providing a signal to Masso?

Hope this helps!

Hi Stephen,

The issue shown in the video was traced to a software bug in one of the spindle alarms.
It has been fixed in the V4 software release.
The MASSO inputs do not use TTL logic levels so your alarms should work ok. Just makes sure your alarm input is relative to MASSO ground.

Cheers Peter

Thanks for clarifying the issue with my TTL comment. I was trying to convey the same information just used the wrong terminology. The spindle alarm on some drivers is powered from the drivers' power supply. In most cases, the power supply for the driver is not the same as the one for the Masso Controller so Masso cannot sense the alarm. As far as I know, this is not explained anywhere in the Masso Documentation.

My solution was probably overkilled but I ended up using the CNC4PC C86 G3 adapter board on my latest build. That adapter has a built-in motor alarm sense circuit and relay control to activate the motor alarm on the Masso. That way I keep the power source from those noisy drivers from causing feedback on my Masso controller. I was not able to make it work up until now because of the bug. Now that I know it's been fixed in V4.0 I should be in good shape.

Hope this helps!
