TriCopter - QuadCopter - Project

CNC is not going anywhere… :frowning:
I will try to take some time the comming weekend to make a cut.

Do you have a sample cut i can try ?

The Flight control board will be arduino Mini Pro 5v 16mhz, with a Wii Motion Plus gyro (3axis) and the Nunchuck accelerometer.

I have receive the arduino yesterday, plug and programmed it.
I am waiting for the PCB board i have ordered.
myrcbuild.com/FLYHIGH300-Flight-board_p_45.html

I’m running on my laptop machine on vacation, so not much here in the way of samples. Let’s get you started with a simple bracket or two.

Boards look good.

Is there WiFi control, from say, an iPhone? Things are starting to become available!

If you are talking about my two copters, no, they havent got the cube sensors. The cube consists of 3 MEMS Sensors and an accelerometer sensor. The two other copters are based on original KK Hardware, so no Accelerometer or MEMS sensor.

Ok and was it working good with thoses board ?

I have finish the design of my quad.
The only thing i want to add is a landing gear. Maybe i will just tiewrap a t-rex one.

Here are some pictures:

Someone will cut it for me. Since my CNC is not done yet… lol

There is a Y6 config that can be done with the same parts. So in fact it has 3 config “Quad” “Y4” “Y6”.

enough for now… LOL

Very cute designs.
I can only tell you, go on and finish your CNC. For somebody with your ideas it is the perfect tool to work with.
What do you need to finish it?

I agree with 17b there. finish your CNC!
i would certainly be placing orders for parts to be cut. oh i might also have a few design for you do “CAD” up for me. but this may come another time. ill PM you if the project comes up. :wink:

… CNC.

I will take some time tomorrow to try that. I will also try to switch back to EMC2 and setup it …

No there is no control wireless … :frowning:

There is an Android app to configure

Don’t have much time this morning… but i have try to cut a “Spiral” sample in EMC2.

The round is not perfecly round… but that way better than what it was looking at my first atempt…

I don’t think the setup is done right. I need to setup it so 1mm is 1mm in reality…

Did you adjust the backlash and do you know how to do this?

Alan, i ain’t try your code since it doesn’t open in EMC2.
I have try ACE converter too and the file is not loading in EMC2… ;(

There is backlash, no i ain’t done anything to adjust it. (Don’t know how in EMC2. In Mach3 there is a parameter i have see)
I still don’t know wich software i will use to control. Any advice ?

I have try both EMC2 and Mach3

Would prefer EMC2 since it’s a free open source.

I use EMC and EMC2 on a second mill. I have no experience with Mach3. Like you i prefer open source and i have some skills in Linux so i have only minor problems to get most things up and running (but not all).
There is an ini file where you can edit the backlash. I can send mine to you as an example if you like.
Just send me an Email with the adress.

Change the file extension to whatever you need. I use “.CNC”. I added “.txt” so I could upload it. Try “.NC”.

Also, there is an end char “%” I think, that EMC might want.

Alan KM6VV

Yes i have try .NC
it’s more about the end char probably. Is it something at the end of all line?

There are two blank lines, EMC may not like them.

I have a few “//” prefacing drill cycles, They are block deletes. EMC may only want a single “/” (slash). See if that helps. Or just remove them. I go through the program first with the // in and block delete enabled, which then just does a move to 0.00" (surface of stock). with a small center drill set to just below the surface of the stock at 0.0", the “drill” lines (N10060 - N10310 for example) thus center drill first. Then I turn off the block delete enable, switch to the appropriate drill bit, and run the section again. The M01 statements pause the program for me. The three sections of drilling are arranged biggest first. I first center drill all three, then drill all three with the smallest bit .089" (labeled as endmill), then just two sections with a .0935" drill, then just one section with a .125" drill bit. sounds complicated, but it’s not. I just restart the program and run the drill sections multiple time to get them center drilled first, and then progressively drilled until all are drilled. No tool comp.

I haven’t ran EMC for a long time, as I run STEP4, the CNC controller program that I wrote.

On mechanical alignment, you will want to adjust the tensioning nuts on the drive screws (leadscrews) that tension the bearings. Also for the follower nut, if it has any. Otherwise, you’ll get backlash. Don’t assume that the software will “take all the backlash out”.

Ask questions on the CCED or my SherlineCNC list. Many more “ears” there…

Alan KM6VV

Alan:
I will check for that tonight… :slight_smile:

Quick update on the frame…

flickr.com/photos/dialfonzo/ … 232345098/

That version is being cut right now…!

Very cool frame! Are the landing gear on a pivot? Do you plan to do some sort of shock absorbance?

Tanks a lot Marcham to say that. I try hard to do something nice… :wink:

No i ain’t think about having it on “Absorbance”, but it’s a good idea. For the next version maybe… :astonished:

The parts are cut and will be shipped today:

I can’t express my exitation … I am so happy to see the result of my CAD drawing… :stuck_out_tongue: :stuck_out_tongue: :stuck_out_tongue: :stuck_out_tongue: :stuck_out_tongue:

More to come.

BTW: the flight board is all assembled now

Those look great! Can’t wait to see it all put together.

Yes me too…!!!
