No Cannon firing
« on: December 18, 2020, 10:11:33 AM »
Hello,

Finally got around to fixing my Heng Long Panther, the RX-13 died a few years ago.

So rewired completely for TCB, bought a replacement airsoft with the switch and a Taigen Panzer III sound module.

Finally got most things working, so many settings  ;D.

The cannon however does not work no matter what I try.

Airsoft enabled/disabled etc etc

I know the AUX switches work as both MG leds operate.

Any advice?

I have attached my config file.

As a note the radio is a Graupner/JR MX-12 with a modified R700 receiver.

Additionally when I fire the MG the tank comes an abrupt halt.

Best regards

Neil

PS I will eventually get around to finalizing the code for the homebrew Scout.

Hi Neil, the one thing I see off the bat is that you have both the cannon fire and machine gun fire commands assigned to Aux Channel 2 Position 2.

I'm not able to test right at this moment but I'm assuming there is a conflict when it tries to fire both at the same instant.

I often put cannon and machine gun on the same physical switch, but this really works better with a 3-position switch, rather than a 2 position as you have done it. Your transmitter has some 3-position switches so you may want to use one of those. The setup would then be:

Position 1: Machine gun fire
Position 2: Machine gun stop (this will be the middle position of the switch)
Position 3: Cannon fire

In this way, when the switch is in the middle position nothing happens. When you flip the switch one direction the machine gun fires, when you flip it the other direction the cannon fires. If you don't like the direction that you have to move the switch just flip position 1 and 3 or else reverse the channel.

This may or may not fix your issue but I'd give it a try and see.

Hello Luke,

I should have said more on initial post.

I tried both Aux switches, Input A and Turret to fire the Cannon to no avail.

The final test was to put the second MG on with the Cannon to make sure the TCB was reading correctly.

I should have also said I downloaded/loaded the latest TCB firmware prior to all this testing.

This morning tried again.

Firstly set main MG for Aux 1, 2 and Input A and all worked.

Set up Cannon again for Aux 2, again no function.

So I did a Snoop which revealed something interesting.

I did a couple of MG fire, which were OK followed by Cannon fire which reported
Fire Repair Signal
Disengage Transmission

Then a short time later
VEHICLE REPAIR COMPLETE
Health Level: 100%

Which is not what I would have expected.

I reloaded the firmware with the exact same results.

Is there a Firmware issue?

I believe my Radio is OK as I can function all sticks and switches correctly.

I have a second TCB which I can try but this has the same firmware.

Best Regards

Neil

If it is firing the repair signal then you probably have the Fight/Repair switch on the TCB set to Repair, move it to the Fight position.

Also, note that Input A is for a physical switch attached to the TCB, not a switch on your transmitter. I doubt this is what you want, setup your functions so they are assigned to transmitter triggers.

Hello Luke,

Eureka, many thanks. ;D

Also apologies I should have paid more attention to the wiki.

In my defence, I glanced over the F/R switch as it mentioned IR and I am not going to use IR.

Also I was using I/P A to remove the the radio from the investigation as it is a direct input to the TCB, it will be used to turn the Airsoft on.

Cheers

Neil

I'm glad it works! And don't worry, I have had many head-scratching moments myself when I forgot to check that very switch.

Using one of the external inputs to enable/disable airsoft is a perfectly good use. Just wanted to make sure you knew what you were doing but I see you do! Sometimes you don't need to control something from the transmitter, just a little switch somewhere on the model is fine, and that is exactly the sort of thing those inputs were designed for.
