Downdraft design questions

Actually, thinking about it a bit further, I assumed your x & Y axes were the other way round (X axis being the short axis.

You may need to swap some pins around for
ddraft4x2.0.y-pos with ddraft4x2.0.x-pos

Just jog around your table first like you did in the sim before adding the trigger pins to confirm its working the way you want..

The operating station is in the middle of the table, on the long portion, so I swapped x and y. Thanks for this additional info, I am sure you saved me some headache.

I am drinking one more last beer, then off to bed. We closed the shop for the holidays, so I have the place to myself this week. You are 16 hours ahead of me, hopefully I will have the solenoids operating when you log on tomorrow... or I will have a bunch of additional questions. :lol:

I got it going! I had to adjust the x and y like you said, also had to reassign some of the pins... see attached hal file. ONLY issue is the gates are operating backwards from what I need, ie: the gate that should be opened is closed and the rest of the gates are open. I can reverse the polarity of the wires at the solenoids... or the air lines themselves... but before I do, is there a way to reverse them in the hal file? Instead of sending power to only the solenoid I want to open, could I instead turn off power to that solenoid?

Perhaps this is a bad idea to have all the outputs powered up for like that?

This is going to be awesome. I have some air leaks to tend to, then proximity sensors are next.

Reversing the solenoid connections will not make a difference

You can invert the outputs with

setp hm2_7i76e.0.7i76.0.0.output-XX-invert true

where XX is the output number

Its not ideal since 7/8s of the solenoids will be on at all times

I swapped the air outputs and presto!

Awesome work but remember it did not happen unless there is video. (and a full report!)
