Question Simtool's homing command/direction.

Hello Everyone,

I have a question regarding Simtool's homing command/direction.

My understanding of Simtools is that it is programmed on startup to home the actuators and find the center point by fully extending and retracting the stroke which in my case is 200mm.

My only issue is I have a setup where the sim has four actuators (one on each corner) with a center pivot point that are all fixed to the baseplate.

My question, is there a way to reverse the direction of the homing command in Simtool. Having a fixed center pivot point, I need the front and rear actuators to home in opposite directions in order for them not to fight each other. The only way around this I found it to have the front actuators disconnected and swapped the fixed connection with feet that are free floating and set my homing timings of the rear and front actuators timing it so the fronts have clearance to home using TBVST 4.5. This is not a great solution and looking for an alternative option.

Any help is appreciated, guys ... I am open to ideas and suggestions. I'm maybe missing a function in Simtools that I have overlooked that maybe a solution, but I am stuck at this point.

Thank you

Yes, you tick a box to reverse direction

However it sounds like you have a 2dof with 4 actuators

It can be done with only 2 actuators


Do you have a picture

Thank you,

I am assuming you are referring to the checkbox under the axis assignment screen. I understand that you can set up the axis/actuator to act in the correct direction by checking or not checking the (DIR) box in this setup screen. But does that direct carry over to the homing ? I don't think it does.

And... you are correct, I am running pitch and roll with support of two extra actuators on the front end to help with the weight.. Thank you

see attached for layout

simtools in your case may trigger a homing sequence of those actuators, but not manage it.
