NC Pod / Re: Not returning to zero

Didn't really answer your question did I Dave.   ;D

I was only "air cutting" the roadrunner on my mill, so as the error was only about 0.2mm I didn't notice a physical position error.

Steps away from zero varied from 1 to 80.  on the DRO.

I just tried a "dry run" with only 5v and USB connected and it still does the same thing

Don't know if this is valid without drivers connected. S'pose it would not make a difference but I'll leave that to the experts.   ;D

Dave I have refitted a LPT BOB to my mill.  I need it running.  :) 

So I can't really do any testing in the machine now.

I need to get on with my new half built router and hope the Pod is sorted by the time I'm ready for a controller.

I can dry run it (5v and USB only connected) but that may not be a valid test.

OK I'm a dill  ;D  I should be "dropped from a great height and publicly peed upon" as my uncle used to say   ;D   ;D

Forgot to reinstall my licence dat. Now it does not stop at around 980

The gcode window and counter still jumps and at the end it still does not return to Zero.

Set your servo time to .00087 and you should be good :)

I have been running tests and it is working well for position. you need to have the latest software on everything.

I tried to set servo time to .00087 but it would not stay and reverted to last setting.

So I downloaded latest Plugin and it had a selection in the drop down of .00084 so tried that. Still not returning to zero.

Then I did a clean install of the latest Mach version R2.0.036 set up motors and estop again.

Now the gcode window and line count jump and it stalls around line 980 of the roadrunner.

Tried updating the plugin just in case it changed. Still the same.

Have the latest firmware. Mach version and plugin. Legacy mode turned off for USB

I think to save my frustration I will set this aside for now and watch for updates to come out.

Glad it is not just me.

It always feels better if someone else is having the same problem.  ;D

Disabling legacy mode in bios has made comunication more stable.

However I have a funny problem.

Set all DROs to zero, run the roadrunner, DROs not ending on zero.  Gcode last move is go to zero but DROs not returning to zero.

Watching the Z axis DRO during code execution. Z spends most of the time at -0.1 and goes up for rapids returning to -0.1

Each time (or most) it returns 0.0025 different than the last. So they add up to a cumulative error by the end.

See pic for screen capture at the end of roadrunner execution.

Where did you get the NCPod from and how much was it?

Oemtech is providing units on a beta test basis.  See the site.

Art is not endorsing this product yet.


I got it working. I tried using it without the SD card. I guess I didn't follow the instructions. Works great now.

What instructions? Am I missing something?  :)

Can you give any more detail?  Are you getting an error?

It looks to me like you would need to make a rather complicated cable or a adapter / break out board.

I think you will find the next version will allow for more connection types.

Also I did hear that CandCNC is planning addon boards for it. Others will probably do the same as it becomes popular.

Yeah that's what it looks like.  After all that is the photo from the manufacturers site.   :)

Great to see a forum for the ncPod at last.
