i've been taking a look at this page wiki.linuxcnc.org/cgi-bin/wiki.pl?SpindleOrientation. what would i have to change to get this to work with my setup? Obviously, where it says "board" i would have to insert my board, but what other changes would i have to make to it to get to work with my 7i96s with servo spindle? i did notice i needed to change the port numbers in the file to match my board. is there anything specific i need to configure to make this work? Thank you for all your help btw.

WOW  4Kg is a lot of weight for a couple 2213 motors and 10" props to get into the air. That said you definitely
wouldn't be worried about the wind. You would probably need the wind to get off the ground. I will admit my
expertise in such matters is limited. If it were me I would probably go with a delta wing or a flying wing design so
it would cut through the air nicely and still give lots of lift for the weight. The old Avro Vulcan bomber would
give a good starting point. Lots of wing area . At that point though one would need to think about what size
servos and or how many to use per control surface.  For my stuff I am staying in the under 1Kg region.
For now anyway. LOL

There are stand alone modules made by people other than  Beckhoff.
one is the Rtelligent RTEC1616 which has 4 PWM outputs

I agree the waveform is weak.

After some deliberation I decided to replace the encoder and try one of these cheap hall effect chips (AS5040). I chose this one because its 10 bit resolution matches the max I read in the WJ200 manual. 

I 3d scanned the top of the servo drive to get the locations for things. (loving this Einstar scanner)
 

The scan wasnt perfect so I iterated the top diving board twice to dial it in. 
   



Then I soldered up some wires and fed them to the fanuc wiring already in place. 
 

Now I have a good 5v square waveform on A B and Z.
 

I will likely replace the 3d printed parts with metal parts once the machine is up and running. I wouldn't want to have problems because the servo gets warm down the road.


 

i think 5V is better, since the 3.3v regulator is already on the board anyway.

DId you mean 7I92+7I77 as I suggested?

I would make a 7i92+one 7I77 configuration with pncconf
Get the basics working and then add the additional I/O

Do not change the basic 7I92+7I77 hal/ini file set until
everything on the 7I77 works.

As I mentioned, checking the encoders on the 7I77 would
be a good first step to verify your cables

BTW those cables are much easier to make with
IDC (press on) connectors.

Also, as far as I can see from the picture, the HDR26 --> DB25
cables are not correct.

They appear to be

HDR26    DB25
1             1
2             2
3             3
4             4
...

But should be:

HDR26    DB25
1             1
2             14
3             2
4             15
5             3
6             16
7             4
8            17
9             5
10           18
11           6
12           19
13           7
14           20
15           8
16           21
17           9
18           22
19           10
20           23
21           11
22           24
23           12
24           25
25           13
26           NC

That may seem odd but that's the pinout you get with
IDC (Crimp-on) flat cable connectors. Its odd because
HDR26's and DB25's number their pins differently.

Thank you for helping me out
Do I need firmware for my boards in folder /firmware/hm2 (For 7i77, 7i74, 7i70, 7i71) ?
I tried Pncconf with 7i92  and 7i76 and then deleted all the lines with errors for 7i76 and linuxcnc started 


 

I have 6S batteries rated at 32AH and 10C weighing in at 3.7KG, so halving that to 3S would be 1.9KG, elctronics and motors and GPS and stuff another KG, plane due to not being able to find anything useful here would have to be styrofoam or that dense pink styro and would need to be covered in fiberglassed resin so probably at least another KG, totaling close to makes no difference 4KG.
I have 2213 motors with 10" two bladed props that can lift 1.1KG each at 4S, probably 0.6KG at 3S ... and writing this the reality kicks in, this might be to heavy for two of those motors ...
What is the weight to lift ratio for a plane that can handle a bit of wind?

P.S.
Sorry for being absent a bit lately, had flooding on both shops a few days back so cleaning all day every day for now.

Yep I remembered that.
I'll just keep plodding along and see how I go.
I've ordered some new flash chips and another dev board so at least I can go back to square one.
Just out of interest, with the WT32-ETH01 module should it be powered with 3.3v or 5v ?

Let me check that... I could have missed it. I'll create a bogus 2-axis machine and check it to see what lines are changed/added.

Thanks,
Jerry

I have used the Home Offset... it's odd.. and I have not experienced it before... but when I made the first axis (A) have a home offset of 50, it went exactly where I thought it would... but then the (A) axis homed in an opposite direction. I don't know why.

My mills... (Monster Mill), (Frankenlab), and (Laguna) all have home offsets. This is the first time I've wired up a 5 DOF robot arm. I will experiment with that more... been out of town over a week now... just got home.

But I had not thought of linking the motion.is-all-homed to an MDI Command... very clever. I'll probably play with that now. It offers more options than the offsets... running routines to check inputs... probe functions, etc... all at the start.

Not sure exactly what I'll do other than the preset location at this time... but yeah... very cool idea.

Thank you!
Jerry

Update: I could NOT find the signal for all homed... or any variant of it. I can find individual axis... but not "all".

if you change the gateware on the FPGA, you have to recompile the hal-component,
the test gui used the json-config, but the hal-component (rio.c) ist generated and need an

halcompile --install rio.c after changes

beckhoff has some servo control modules, but they literally cost more than buying a delta b3 full kit. So probably not worth while.

Uprights for V1/V2 minimonster. V1 is single drive aluminium base frame, V2 is dual drive, granite base, these uprights can be used for both. As you can see, for this first one I am re-milling out of the old large predator uprights. Not reusing any features, just working around the holes to use it as stock.

I'd already made a Z axis, but I went and changed a few things on it, so I need to make another.
