Picloc 3x setting experience etc.

Did my FW upgrade today, from *.72 to *.76 and must saw what a difference. Running now on pro X3 with high P gain. Whole CS gimbal is so calm now and the testflight went very well.
Good job George!

Thanks for the update, Zellevision.

Does anyone know what servo refresh rate a Spektrum H6040 can be used on? I've had it at 333hz for a long time and just changed it to 400hz. Seems ok, but I don't want to burn it out.
 


Latest firmware works great for me too.

I tried one of the adapters from kopterworx to keep the picloc as far away from the servos as possible
but stil the magnetometer is drifting.

@Tahoelight - would like to help - please send me an email with the following in the subject "TAHOELIGHT-PICLOC" ..

@meme - Unit must not be moved on startup until the servos become active. If there is movement, the gyro's startup calibration will get busted, and that effect you mention is then happening. if not resolved like this ( Please use latest firmware v56_76 ) let me know so that we make a skype call and I watch your setup so that I can identify what's the culprit.

@yeehaanow - Most digitals update the motor at a fixed rate regardless of the input pulse rate.... They either work or don't work at high frequency.
Only Analogs can be damaged if using too high frequency. That's why I've made a nice selection of servo refresh rate outputs from 50Hz up to 400Hz.

@redridinghood - Is the wolf around ?? The Mag is afraid of it ;)
Sorry for the stupid joke.... I feel a bit strange talking to redridinghood.
I am working on the magnetometer hard iron calibration... it should be much better in next weeks.
The Mombasa would then perhaps upgrade my vote for president....

Hi George,

New Firmware indeed works better. However with (Pro *.76 X1) i do not have manuel Pan. It works ok with the 3X version and the previous *.72 & *.75.
The new version have a very fast pan and it's a bit difficult to set it to a slower rate.
Roll drift issue is different with the older 86.* versions while panning the mount 360. older version roll to right side. With *.76 picloc powered on to east it drifts to the right when panning to north and to the left when facing south. Still cannot disable the Acc.

Hardware = CS360, Futuba 9352, Dx8 & 2slipo

@Remoteworks... OK.. I will check again the Pan code... no change was done to the Pan firmware. Will report back in evening.
Perhaps it would be best if we met on skype for you to demonstrate the issue and let me find a solution.
You should be able to disable the ACC... what's happening when you select 'NONE' in 'Calibration Tab' -> 'Mems Calibration' -> 'Accelerometer Correction Influence'

Would be interesting to have the Artificial horizon enabled, and you pan the Picloc box 'only' on a table ( ie taken off from the mount ).
When you pan, the horizon should not move.

Hi George,

With firmware *.70/72/75 i can select "NONE" in the calibration tab and it works ok with the Artificial horizon and no drift, But it does not save. As soon as i power it Off and On, the setting is set to default again. Using Firmware *.76 X3 and selecting "NONE" has no affect (default setting). only Low, high etc settings save when powered on/off.
Artificial horizon moves from left to right when turning the picloc (stationary on the table)

Let me know when you are available on Skype

before i forget, with *.76 X1 manual pan works if i select ch3 from input matrix

Definitely something wrong.
Please send me an email confirming your address, so that I can swap your unit... ASAP.
in email title write "REMOTEWORKS - SWAP UNIT"

Tested the Std *.76-X1 version. This has the same pan problem problem as the Pro *.76-X1 (ok with Std *.76-X3)
Also the std version has the same horizon problem when turning the picloc (stationary on the table). after recalibrating it in the software the horizon is ok, but after re-powering the picloc the horizon is cooked again. The only settings i can save in the 'Accelerometer Correction Influence' > Low, default, high. selecting 'None' has no affect
The picloc's with *.72-X1 firmware worked ok when selecting 'Accelerometer Correction Influence' set to NONE if it would safe that setting!
This does not look like a hardware issue.

Ok.. Thanks for your feedback. I will look into this ASAP. As you describe it, it sounds like a firmware bug, but, I can only ascertain after this evening.

Thanks ! George

Hi George, a bit more info regarding the pan difference *.76 X1 >< X3. Deselecting the 360 servo option gives a working pan. No difference in Stick power. 1>< 60
Reflashed to hd55 gives a good working horizon.

A new wrinkle with v56.75 Manual Pan is that it does not entirely disable stabilisation. Yesterday (with the big heli) the Pan stabilisation was working pretty well during hover with fishtailing and stopping & starting, but going for a run with Pan on manual the Pan axis still tried to stabilise through the second 90° of the 180° left turn so that the camera was facing to starboard on the way back.

I had wondered whether the magnetometer was having a hard time with the large stainless steel bed upon which the big heli sits in the truck. So one of the tests yesterday was to enable the magnetometer in the field. No difference! The mount still rotates steadily clockwise.

Therefore, with the Manual Pan issue and the ongoing magnetometer problem I have now downgraded my vote to Governor of California. The presidential vote is reserved for when not only these are sorted, but when saving setups to file is introduced. :)

Manual Pan-Question:
When i switch from Pan-stabilization to manual Pan, the mount turns around 180° (now looking back) and is shaking. switching back to stabilization, shaking stops and is working well. turning on manual pan again, mount turns again 180° (now looking forward) and is shaking. turning on stabilization: shaking stops

What is wrong? i thought, the manual pan is just stopping the stabilization by switching the switch and thats it?

Whoops! Seems like it is the Pan axis that has been accidentally corrupted this time.

I used to have that problem with the magnetometer. When activated it would sweep around and face South - regardless of the heading when the system was powered up. It is now different. When the mag. is enabled the pan axis steadily and endlessly spins clockwise. I don't use it at all.

The manual switch used to disable pan completely but something has changed in v56.75.

Come on Governor, sort it out.

well, my mag is off.
when i try it on my big mount, something different happens: manual pan on > no turning around, no shacking. but also no more movement, when i use the sticks. only a little little one i see.

What firmware are you running? HD55 displays those symptoms for proportional servos unless SLEW is selected. If you are not already there move to v56.75 OR go back to v.055 or vE055.

I'm using 56.75 :(
I saw this symptoms to - on roll. but there i turned slew on to get a movement. with non-slew, i had also these little movements. but now, slew is not on and on the display i see a movement from 0° to 0,25° in only one direction total. thats all. so, no movement to -0,25° or 0,25° to 0,5°...
