"Hi Lloyd,
Thanks for testing. Yesterday I rebuild the controller stack of my quadcopter. Installed the external magnetometer again. Did a manual calibration in the Mission Planner and everything is working as it should.
I guess I began to doubt…"

Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"Hi Jan,
Well, I disconnected my external compass and got the same results you did.
First, in CLI, it reported "Not healthy" as expected.
But like you observed, in the HUD, the HUD's compass still…"
Henk de Groot replied to Frank giglio's discussion External Magetometer"Hi Lloyd,
I did what you asked. I pointed my APM board North, started the CLI and tested my compass. The CLI returns the message 'not healthy'. I repeated this a couple of times.
Then I checked the Flight Data screen. There the yaw and…"
Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"Jan,
I do not understand what you mean by putting the APM board along two sides of a book.
If you point the APM board (input pins forward) toward North, do you see 0 (or thereabouts) on the CLI? If you then point the APM west, do you see…"
Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"ummm. I would NOT cut the trace deeper - who knows what damage you could do. Especially if the ohmmeter shows lots more than 0 ohms. Let me think about it and get back to you.
Perhaps someone else has an Idea.…"
Henk de Groot replied to Frank giglio's discussion External Magetometer"Hi Lloyd,
The test result is somewhat unexpected.
First I checked with my multimeter. There is an infinite resistance over the pads. So in theory that means the trace is cut.
Second I checked in CLI with the on-board compass. This gave back a nice…"
Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"Hi Jan,
I know of three tests.
First - take an ohmmeter reading between the two pads that you cut the trace between. If you cut the trace, you will see an ohm reading of much more than 0 ohms - like…"
Henk de Groot replied to Frank giglio's discussion External Magetometer"Hi Lloyd,
I've installed an external magnetometer on my quadcopter using your manual, but I'm not entirely sure if it's working like it should.
The manual states that it's required to cut a small jumper trace on my APM 2.5 main…"
Bill Bonney replied to Frank giglio's discussion External Magetometer"I grab a screenshot of the connection from the pcb layout program and you can see the link. The solder pads each side are you can change your mind later and put a blob back."
Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"Chris - I see that you edited my text a bit. Nice job. And nice job loading it onto the wiki. You must be a wiki editing animal. I'll PM you. You know, its much easier to describe things in forum threads. In…"
Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"Frank - you have to cut the trace. I received the picture and hint at what do from 3DR customer service."
Frank giglio replied to Frank giglio's discussion External Magetometer"Thank you Lloyd, You have been very helpfull. I have done most of what you explained but the cutting of the jumper trace. This jumper trace already comes cut as default or are my eyes getting weaker? I actually thought that this trace would have to…"

"Lloyd: That was a brilliant tutorial! I've added it to the manual here.
You're great at explanations. Would you like to join the Documentation Team? I'd be happy to give you wiki edit access. Please just PM me and we can…"
Lloyd DeForrest replied to Frank giglio's discussion External Magetometer"I figured it out and wrote up a brief how-to in the last post in this thread:

Let me know i you have any questions."

Hello I am new to this game so any advice would be appreciated.We are trying to program the APM 2.5 to fly parallel flight paths 40 meters apart. We are getting inconsistent turns.Some times they are perfect but other times the they are all over the place.Looking at my graph and looking at the mag_field and ch3 throttle together, we found that they are consistence.Could this mag interference caused by the motor play a part in our results? I have uploaded the tlog file and would like any…See More
