Notice how the Duex heater pins are inverted in the listing.
exp.heater3, exp.8, !duex.e2heat, !duex.pwm1 exp.heater4, exp.13, !duex.e3heat, !duex.pwm2 exp.heater5, exp.18, !duex.e4heat, !duex.pwm3 exp.heater6, exp.23, !duex.e5heat, !duex.pwm4 exp.heater7, exp.31, !duex.e6heat, !duex.pwm5So try using: !duex.e2heat

You mean to say duex.e2heat (no bang) ?
-
I'm lost, it's inverted so it should not have the " ! ", right?
-
@matt3o, that is my interpretation .... but then I am no expert on config.g .....
-
Example: !fan2 This means the pin labelled FAN2 on the Duet, but with the drive signal inverted. -

Some of the Duex signals are pre-inverted by the connection to the Duex, so to use the pin names, you need to add the ! to invert them again.

@Phaedrux okay, the behavior was too erratic, I took the time to re-wire everything. On both the duet and duex. What drove me off is that all heaters were shorted when this started happening.
I use CAT6 wires for all not power hungry connections. I realized that they are convenient but also not easy to peel and crimp. They are just one stiff strand of wire. When you peel or crimp they tend to weaken in one tiny spot and break. Everything seems fine at the beginning but they eventually fail if damaged.
Now I've been very careful when peeling and I loosened the crimping tool so it applies less force.
I believe that was the problem. Everything seems to be working now. BTW, it works without the
!in the heater name. That part is a bit confusing in the doc... well at least for a total noob like me.Thanks everybody for the help... I hope this is fixed...
-
Let us know how it goes.
-
I think I got the heater naming....
exp.heater3 is an alias on !duex.e2heat (note the
!). So to invert it you either use!exp.heater3with an!orduex.e2heatwithout it. At least this is my interpretation... -
Multiple names on a line are aliases for a single pin. Some pins (primarily heater pins) have an inversion between the processor and the corresponding output, RRF3 will automatically allow for this inversion. These pins are marked with a * after the pin name in the list below. For legacy reasons some Duex pins are inverted or not, depending on the name/alias used to access them. This is indicated with a ! in front of the pin name in the sable below. e.g. exp.heater3 is the same pin as !duex.e2heat the ! indicates that the logic of the pin is inverted when referred to as "duex.e2heat"
