Retrofitting a 1986 Maho MH400E

We have a little problem with the e-stop double bouton. Gmoccapy activates only after we release the bouton, so the 24 volt from the Mesa to 209 joint to activate the 19K1 is not going to be present when we press the 3SH1 bouton (the second bouton contact).

One solution it will be not to drive directly gmoccapy.v-button.button-0 pin from the mesa bouton input, but instead pass the signal from a timer that pulse for a fix time.

Never mind, I was wrong, the boutons pin of gmoccapy have different behavior than soft boutons on screen. They activate gmoccapy as soon you press then and not after release them.

Hi John,
Interesting observation. I hadn't notice that behavior. For testing I have the Physical start button from the the MAHO connected to close the EStop through one set of poles, and to signal V.button.0 through it's second poles. While pushing and holding that, I have been clicking the on screen V.button 1, and it has latched fine.

It should latch even without V.button 1, I thing.

You could set it up like that, but since all the LinuxCNC interfaces are set up for a separation between "E-Stop close" and "Machine Start" I decided to implement it that way needing both to be pushed similataneously.
