ESC/Motor calibration on CC3D via Cleanflight

[PropsToYou]

I';ve noticed I have one motor firing up significantly earlier than the others so went to calibrate/sync my motors using the cleanflight software.
However, following the standard protocol for using Cleanflight with the Naze doesn';t seem to work for the CC3D:
- Plug into computer
- Put throttle to max (using on-screen slider)
- Plug in lipo
- Bring throttle to zero (using on-screen slider).

I get some beeps but when I try bringing them up together again I still get that delay.
Any tips?

Were you in acro/rate mode when you did the calibration?

That shouldn';t make any difference

When you run the motors via the slider it bypasses all that stuff and just sends the values to the ESC.

Any tips?

What are you running on the ESC? BlHeli?

No need to calibrate them just set the min/max motor values in the Cleanflight to match those in the ESC Well just beyond so that they do max out.

[bazzerh]

this sounds like your min throttle is too low. try adding 10 or 20 to your value

They';re running SimonK (It';s these ones here

How do you mean match them to my ESCs? They';re 12A ESC';s but how does that equate?

Thanks buddy, I tried this and it helped a teeny bit. Now two motors start together and the other two a little later. This change happened after increasing min-throttle by just 10. However, even if I popped it up a further 50 it made no further change.

I';m not even sure why I said what I said.  I shouldn';t post at 4:30 in the morning.

If you had BlHeli you could have set all the ESCs to the same min/max values through the blheli suite and matched them in CF this would have done the same calibrating them.

But as you have simonK stuff you will have to stick to the normal calibration.

How are you connecting the FC to the PC  USB/serial  do yopuo have the ESC power line removed

These effect how htre ESC powers up and may not get into programmingmode.


sorry if not making much as I';m on the sherry.

Damn wish I could be on the sherry. Got a spot of the winter man flu.

Ah yeah. Well hopefully in the new year I';ll be swapping out both motors and ESCs anyhow but wanted to get current setup working nicely for now :)
Can connect FC to PC via USB or BT, both yield the same results. ESC';s are fully wired up.

i calibrate directly. i have a home brewed 6 way splitter lead. plug all ESCs into it, then do the manual calibration via TX.

How would you go about calibrating directly via TX?

[quadfather]

Plug the ESC into the throttle channel.  Throttle up, power ESC, throttle down, done.

If you use a splitter like Ynot6 mentioned you can do all ESCs at the same time.

Ah I see, so completely bypass the FC and plug the ESC';s straight into the RX? Is the adaptor to allow them to be powered at the same time?

[quadfather]

Typically the splitter is just for the signal wires.  If you have your ESCs soldered to a PDB you can just connect a LiPo to it to give them power.  Remove the signal wires from the FC and connect them to the RX directly.  Of course, if your signal wires are soldered then it';s a bit of a pain.

Gotcha.
As my ESCs are just connected with the standard 3pin servo connectors, then presumably I can literally just plug all 4 directly into my RX? Will this in turn also power my RX?

[atomiclama]

Don';t

It will work bu then you will have calivbrated to the TX range not the FC range which may or probably notbe the same.

Connecting via USB will not power up the ESC untill you connect the lipo so should be ok. This should work and is how I did it untill I got some BlHeli ESCs.

If you power up via the serial port from say a usb -> serial converted then the power will feed into the esc, as you have them fully wired and the ESC will power up at the same time as the FC, this will probably not work.



MAn flu pah good sjhot of whisky will help that.  ::)

[atomiclama]

Just thought of another reason not to calibrate from the TX, don';t knoew about your setup but mine is jittery +/- 5us not a good idea to calibrate from that.

From the FC it is rock steady not measurablel jitter.

[PropsToYou]

So other than the method I';ve already tried, what ways are there to do it via the FC?

[atomiclama]

If you start the motors fromm the configurator motor tabs, what is the difference betwenn the first motor starting and the last?

Is it alot?

I would just set the min throttle to the value that gst sall the motors starting at the same time.

I have found that mine do not start at the same time but once spinning I can drop the throttle down lower than that required to start them. I just give it a blip at start up to get them all going.

Ah sounds the same as me then. First two spin up at 1171, the other two at ~1185. However, even if I bring min-throttle up to 1200 there is still the same sort of gap. As you said though, once they are spun up I can drop back below that level and they all keep going.

[atomiclama]

Strange though as setting min throttle to 1200 that should all start up at that value,..


I don';t think yo uhave a problem.

Just fly and enjoy  ::)

the way I calibrate escs on the motor page is click the warning tick box thing, slide the master to max, plug in battery, wait for the tune to stop, untick the warning box thing which instantly sends your min command to escs to calibrate the low end. ive had more success doing it this way rather than moving the slider down.

also a way to do it via the cli which is

set min_command= 2000, save and exit
go back in cli - set min_command = 1000, type save but don';t hit enter
plug in battery, wait for calibration tune
hit enter

See this is the way I';ve been trying. However, when I plug in my LiPo, instead of getting a tune, I just get a looping one tone beep with a 1 or two second gap in between. It doesn';t stop and seems to only come from one motor. Then I bring the slider down to the bottom and it plays the standard startup tune but this seems different to what other people show on YouTube

That';s neat

has anyone found a solution to this im having the same problem with the motors spinning. will it fly normally? pretty new to this dont want to start a thread or crash the quad...

The problem was with the tones on calibration, not the spin up. What do your motors spin up at?

[bobbysbite]

Sorry I should have put a bit more info.. I have the problem with calibration method I move up slider connect battery and the beeping doesn';t stop, so I drip the master and it beeps a bit more  2 spin at 1169, 1 at 1174 and one 1066 I think off top of my head I can confirm this later when I get back home.

So you don';t drop the slider until the beeping stops.
What beeping does it make when you plug in the flight battery, does it play a tune or just a constant series of beeps

[bobbysbite]

That';s the thing it doesn';t stop beeping its constant with a break in between. So I just drop the slider to see what happens plays a little tune then

[Cheredanine]

Yeah trying to understand what beeping it makes when you plug the battery in, it should play a tune, not just a constant series of beeps of the same tone and duration.

What is your ins command,  min and max throttle set to?
