Hi Guys,
My simulator is just about finished, yay! I am just waiting for the new high torque motors to arrive (built it with wipers for measurements sake), and then I can finally get her going, and make a new thread where I will document everything. She's made completely out of 4.5mm thick metal, and believe you me when I say that it weights quite a bit. Never the less I have a few questions before the new motors arrive and I get her all done and ready for painting...
Firstly, since my sim looks just about the same as Thano's joyrider, I was wondering whether it is possible to set a "default" or "park" position, so that when the AMC is turned on and you want to get in, the sim automatically leans over to one direction, to make getting in (and out) easier, and whether this "park" or "default" position can be programmed to a button, so that you can simply press this button when you want to get in or out of the sim.
Secondly, when I measured the amount of travel I have available for each of the 2 axis's, I found that on the one axis (up and down), when I center the sim and then start measuring at 127 on the AMC, I can go up to about 247, and down again to about 10. On the left and right axis however, when I start at 127 with the axis centered as well, I can only go to 200 when leaning to the right, and to 60 when leaning to the left. So I am wondering if it's possible to configure the AMC so that it never sends values higher than those described above, in order to make sure I never overdrive the motors, or try and get the motors to do something that simply isn't possible mechanically? I am already busy mounting the safety switches with the diodes as Thanos suggested in an earlier post and video, but I would feel better knowing that the sim will never even try to reach a value that is not mechanically possible?
Thanks so much for all your help thus far, I am looking forward to your reply on this one!
Cheers for now!
Ps, one last thing, I assume that the KP values have got something to do with this as well... What exactly are they for, and how do I go about setting them, if it is even required at all? At the moment I have 1.1h installed with the 18mhz crystal.
