It's done! Or at least, done-ish.

tronicgr I edited the last reply to you in this thread to add some relevant info and some comments so if you read it previously maybe take another look. =)

Ha a sim is never "done", you will be pulling it apart and tinkering with it soon enough Looks great! i see your vid onxsim forum and the motions looking really good. When you get a moment would you mind posting a screen grab of your amc settings from fabis tool and also posting the current pertinent VFD settings you are using with that motion? Thanks and great work! pleased your build went a lot smoother than mine is

Possible problem found: The shielding on the wiring for my emergency stop button wasn't grounded. I guess I didn't think interference mattered on an on/off circuit. I've now resolved that. The USB cable is only three feet or so. Thanks @thanos. I didn't think anything showed on the video, I'll have to look again! Edit: Wow I didn't even see the super dim characters, just thought it was video compression until I looked hard, but even at that it's odd the display didn't switch to showing receiving data etc. until the thing had already been moving for a minute. I also hadn't seen the display change when I hit the emergency stop somehow, it's supposed to show the slider bars at that point? Here is a picture of my wiring: Emergency stop is attached at the bottom left. Thanos one other thing while I have you on the line: Very small movements (like very light turbulence) it seems like I can feel it move in "steps" if you know what I mean. Some part of your description of the improvements to the new 2017 AMC board made it sound like maybe it has more subtle control, is that the case? If so, how difficult would it be for me to upgrade that? These movements I'm referring to are too small to see, but I definitely feel them, almost constant when flying. Thanks for the reminder, didn't even think to look for your edited post. You could upgrade the position sensors to 12-bit digital ones as I describe in the latest firmware. Then you will have no noise and 4096 positions instead of just 1024 with standard analog position sensors. If you want more precise control of the analog output to the vfd, the new amc1280usb v2 (2017) has upgraded 6dof ext board that has option for 12bit DAC that means it will output 4096 different speed levels for the vfd (compared to 256 levels before). I can do great discounts to existing amc1280usb owners, for easy upgrade to the latest hardware. Just contact me via email. Thanks Thanos

Thanks Thanos, tronicgr I'll email you. Can you link recommended sensors? paulg100 Exactly, that's why I said "done-ish" =P. It will never be truly done.

Another demo vid guys, I just started trying to get my first Racing game tuned last night. Here are the results so far. It's a WILD RIDE!

Quick question about b083 Carrier Frequency guys. Noise aside is lower better or is the optimal setting somewhere in the middle?

the higher the carrier the more chance of inducing EMI and also may shorten the life span of the motor.
If it does not cause emi problems and your not concerned with possibly shortening motor life span then just crank it as high as it suits.

Thanks Thanos Its nice to have a 12 bit accuracy in the controller, but lets not forget what bit precision is coming out of the game . Actually many games output integer values (~4milion positions) then the motion software compresses that to 16-bit or 8-bit available positions. Then the actual hardware is compressing more the available positions to use the whole range of the sensors. For position sensors you will have smoother motion with 12-bit sensors.

Hey guys, just wanted to mention I'm still struggling with just one problem. Direction changes on the actuators are too abrupt. I'm playing with settings trying to smooth out the accelerations without losing too much speed. It's a delicate balancing act.
The problem is that when you are pitching down and suddenly start pitching up, or rolling left and suddenly start rolling right, you get a bump that is sharper than anything I've ever experienced in actual flight.
What I need is a nice expo curve setting for acceleration and deceleration (found it!). I'm playing a lot with F002 and F003 on the inverters as well as PID and max speed on the AMC.
If anyone has any advice here let me know. I'm going to go back to the VFD manual and see if I can find anything else to play with.
I'm having a blast with the sim! I have lots of folks here to thank for that, you know who you are.
Trip
Edit: A097 and A098 seem to be for setting accel and decel to curves instead of linear, looks like exactly what I was hoping for! RTMF Trip! I'm nervous about playing with inverter settings on my own but his seems safe.

keep us posted trip, I have the same problem, would be good to know if theres a way of smoothing direction changes without affecting responsiveness.

Post by Trip Rodriguez on Apr 17, 2017 1:52:35 GMT
For flight I'm definitely willing to sacrifice a lot of responsiveness for smoothness. This past week I was running with a PID of 2, 0, 0! I'll let you know how I make out.
