Jim Phelps replied to Jeremy 's discussion Lidar Lite not working
"Jeremy,

I assume from your last reply that you have not gotten your unit working yet. I DO have the unit working standalone, and have been able to getting some readings from Mission Planner.  However, I am still having some issues.

"Paul,
If the vehicle is moved before the initialization process is complete the yellow flashing light will never stop.

Jim Phelps replied to Clay Cranor's discussion 3d printed props in IRIS
"Clay,
I have been using a QIDI Tech printer that has a heated platform.  The platform has thick layer of blue color polymer material.  Everything seems to stick to it.  As a matter of fact, most often we have to put some real craftiness and elbow…"

Jim Phelps replied to Clay Cranor's discussion 3d printed props in IRIS
"Clay,

What do you mean when you say the plastic needs a different build platform? Are you saying that it is not sticking to the build surface?

What 3D printer are you using?

Jim Phelps replied to Clay Cranor's discussion 3d printed props in IRIS
"Hobbyking sells a thrust stand.  I bought one, and it is quite handy, and inexpensive.  With a thrust stand you could baseline test the readily available props (unless mfg data is available), and then test your 3D printed props against that data. …"

"Chris,

I have some experience with 3-D printing propellers (for ducted fans).   I have not been successful yet, but I have not been very active with it lately.  Right off the bat, you are going to need to find a suitable plastic material.  The…"

"Matt,
I am aware of these interface modules.  The information about why these are necessary is sketchy.  Do you know why these are necessary?

"Dale,
Your post is not easy to follow, but I understand that you had some mixed results with the NEO M8N you bought from GoodLuckSell and ucenter.  I want to reply to your post because we also have two NEO M8N units from GoodLuckSell.
We have no…"

Jim Phelps replied to Daniel Domit's discussion Iris+ Dropping suddenly. ("Too high above sea level" 3DR answer???) in IRIS
"Daniel,
I'd say they were correct.  The IRIS+ ThrOut is typically over 50% throttle when in it's most basic configuration; short legs, not gimbal.  When the longer legs, gimbal and camera are added, the ThOut increases proportionally.  Additionally…"

Good Luck. They are very helpful on the phone, but it may take a while to get what you need from them.  Patience!
What did you order?
