Different curves for each direction?

[manu]

I'm planning to program the servo movement for a retractable motorpod. To achieve this I need separate curves for both directions.
Is this possible?

My initial thoughts are..

two mixes. one set for x>0 the other for x<0

But sure someone else will have a better plan!

If it's only onw servo I think you can use only one curve for both directions..

What do you mean with 'both directions'?

one direction from 0 to -100 (negative) and the other direction from 0 to + 100 (positive) or
one direction from -100 to +100 and the other direction from +100 to -100 ?

It might be more useful if you could describe exactly how you wish the output to move. As it is retracts, are they controlled by a switch?
If so, start with assume the switch is set with the retracts down. You change the switch to move the retracts up - what should happen?
Then the retracts are up, you change the switch to move them down - now what should happen?

Perhaps he means different speed profiles going up versus down?
That can be done by using a few mixes and curves along with the speed profiles.

Or perhaps sequencing the covers for the motor pod? Again that can be done.

Not much you can't get done in ER9X, but you do have to know exactly what it is you want.

If you really want different curves in each direction:
Custom Switch 1: OR SW3 !SW2
Custom Switch 2: OR SW4 !SW1
Custom Switch 3: V>ofs CH6 99
Custom Switch 4: V<ofs CH6 -99
Curve1 one direction eg: -100 -13 45 81 100
Curve2 other direction eg: -100 -83 -55 -6 100
CH08 +100 FULL Switch(GEA) slow(u3:d3)
Ch06 +100% CH8 Switch(SW1) Curve(c1)
Ch06 R +100% CH8 Switch(SW2) Curve(c2) (Replace mix, not add)

Flip the gear switch, ch6 follows ch8, but with a different curve in each direction.

Edit to suit the requirement.

create a flip-flop logic. then apply the curves depending on the state of the flip-flop. the flipflop switches each time you hit the limits, but you always have to go the full way... stopping half way and going backwards would not switch the curves.

i have attached a sample config. am just starting with er9x, sure there are more ways to solve this and probably more elegant too
