Delays on IBU2U

Postby Lotuswins » Wed Nov 29, 2017 5:01 am

Okay, set track recoil speed to 50%, track recoil time to 10 milli seconds....recoil was more pronounced but still have delay. Set it to 100%/10 ms and it gave me an overcurrent warning (3 light flashes repeated). Tank really moved then, but still has delay.

Where do my settings differ from yours?? can you post your .ini file for comparison?

thanks, Jerry

Jerry here's where I'm setup for track recoil.

Pictures attached

In your ini files I see you have brake simulation on. I don't have that set on any of my IBU2U boards.

With your settings I did not have any noticeable delay on the recoil of the barrel or tracks ImageImage

Thanks Carl, I tried removing the brake, no luck. I'll try the board in another tank to see if its something to do with the antenna/reception this being a partially metal tank. I've switched receivers once already so that isn't it, but maybe something is distorting or attenuating the signal causing the delay. I know, really slim....Jerry

Jerry is the airsoft setup you are running with the relay the possible source? Could you possibly connect a servo to the servo recoil port on the IBU and see if the recoil servo is initialized immediately or with a delay just for a test before you investigate the radio?

I have a full metal Sturmtiger with an IBU and no reception issues :thumbup:

Hi Carl,

I tried putting the board on the bench, still have the delay. It is the worst when it is first turned on, then will get slightly better as it goes, sometimes it actually is near where it should be then it reverts. Now I notice that I get two flashes (low battery) when I turn on the smoker. Turn off the smoker, no flashing lights. Run the tank on the carpet with turns, no low voltage alarm...turn on the smoker, and bingo, two flashes continuously. I'm running a 4600mah lipo....so it shouldn't get a low voltage alarm until, like, forever!..... I'll try the servo to the recoil servo port to see if it beats out the cannon, then to perhaps a blank servo port on the receiver to see the difference?

Carl,

Servo off the servo port is with everything else (recoil/sound) and has a delay.......I didn't try the servo into the receiver as its way down in there...maybe later.

Jerry are you running a Tarr smoker that's the IBU style? With seperate heating port and fan plug?

That low voltage warning is quite interesting. ( with the smoker plugged in).

I'm curious to see if when you fire the main gun (servo) if it's immediate or delayed.

Can you try a different smoke unit just to check? I doubt it's a smoker issue but worth a shot to narrow this down.

Not to be silly but is your battery good? I've had brand new lipo batteries that I swore were perfect turned out to be duds. Simple swap to check if guess.

Jerry try to send Ivano at IBU an email. Tell him about your situation. I had a problem once over the summer and he helped me out fast

Where did you source the board?

Thanks Carl, I'll email Ivano. I'm not running a TARR, but a V2 Taigen smoker. Battery is a year or better old shorty that I used to race with (100C) so I don't think that is an issue....since it will run the tank fine with no alarms under heavy loads. No, its connected to the smoker circuit I am sure. Perhaps I should reupdate the board, and see if that helps. I sourced the board from Ian at RCTankElectronics.

thanks again, Jerry

Jerry you're welcome. Ian is tops in my book, very helpful and informative seller. He is THE IBU guy here on the forum. Ivano is just as kind and helpful too.

A thought.

In the .ini files have the smoker setting been altered?

I had a stock smoker quit on me the other day in my KV-2 . ( Running Elmod fusion) Tarr is my smoker of choice.

Keep us posted with the resolution.

Carl

I see in your file you have min smoke set 100%

And Max smoke set at 100%

Mine are 60% - 100% , I don't think this would make a difference to the board though Jerry.

Not a bad idea after you speak to Ivano or Ian to ask if you should flash the latest version of update for the board.

Carl,

I haven't rec'd a reply from Ivano, so I think I'll just contact Ian and see if he will test this thing to see if it works correctly or not......

thanks for all the help, and I'll let you know of the results. BTW, I had already flashed to the latest update.

Hello Jerry,

If i understood correctly ...

You have an airsoft equipped tank.
I suppose you set the recoil/airsoft into ini file to 1 (airsoft mode).
You have an electronic switch to enable/disable the airsoft motor.
Also you have a servo for barrel recoil which is connected where ? to IBU servo recoil port ? or to Taigen recoil port ?
The delay described affects the servo movement ?

Thanks

Hi theibuman,
I have a Taigen Panther F, with airsoft cannon and have added IR Emitter, receiver, and flash LED. I had relays to interrupt the Airsoft cannon motor, directing the negative pulse to a relay which closed its contact across the Airsoft limit switch, emulating that the card should emit the cannon sound, and the track recoil. The card was in Airsoft mode, but I also had it in mechanical recoil mode also, but it had significant delay in the cannon fire when asked to fire. When the airsoft was enabled, of course, the delay wasn't noticeable as the motor has to wind up the spring anyways, but when asked to just fire IR emitter/noise/track recoil, it has significant delay. The IBU2 base units I had purchased before this IBU2U unit have no delay, in fact no relay is needed to enable the cannon noise/track recoil with the airsoft motor signal interrupted.

I have since contacted Ian again, and I will try the card with only IR equipment attached to see if the delay is still present. I'm waiting for some cables to arrive to enable me to do a configuration to attempt that, I should have it done by next week (The Panther has since been rewired for a Open Panzer TCB, since I had turning issues also...due to the low friction of the track/ball bearing metal wheels/ball bearing gearboxes). If this IBU2 base does still have a delay, then I'll send it back to Ian for testing, at least he has agreed to it.

Hi Jerry,
I think delay come from the switching time of the relay, which voltage has the relay coil or better do you know relay brand/type ?
Thanks

Hi Jerry,
Your mod has to be done as per attached schematic, not phisically tested, but should work.
You need two 5VDC (or 6VDC) relays, using 12VDC relays with 2S Li-Po the relays switching time become slow.
Using your original schematic the board switch input can be damaged permanently.
Also i suggest (if not done yet) to upgrade to latest FW version.

Thanks for the schematic theibuman, nice thought on the relays, but I'm using 6vdc units sourced from Mouser and Digitec. I can hear the relay click clearly, and its pretty fast. You noted it could damage the board switch input the way I have it wired, so I'm curious what did I miss? I see you switched both sides of the airsoft motor over to the relay K3, are you worried about inductive discharge from the relay coil? I already did the latest FW version too, thx.
Hi Carl, I'll try the servo recoil once I get my bits from Hobbyking (from Portland, so should get them Thursday at the latest. Tank is converted over to the OP TCB, so I have to test on the bench with a test rig I cobbled together out of spare parts.
thanks for the thoughts, I'll let you know the testing results....Jerry

Hi Jerry,

The IBU2 is designed to be plug & play around the stock tank wirings.
The microswitch input (pins 1 & 2) present on xenon connector are designed to work with a switch that momentary short these pins.
One of the two pins (pin 2) is the input to microprocessor (internally tied to 3V3), that accept 3V3 level at maximum.
Even if there's a protection circuit (resistors and diodes) by connecting a negative pulse that come from a motor driver circuit referred to battery voltage is a risk.

Please keep me updated
