AMMEND Needing help with WIRING some steppers to arduino.

[Brian Lawrence]

Your talking to an electronic idiot who barely can operate his remote control.

The trim pot is next th the chip on the driver board. It’s the round metal thing about ⅛” in diameter. You can adjust it with a Phillips screwdriver. To check for continuity you’ll need an ohm meter and measure the ohms between the red motor lead and which ever one is next to it on the connector. Same thing with the other pair. You should get a very low reading, a few ohms at most.

What part of the city are you in?

 

[Brian Lawrence]

I live in Huntington Hills, and You?

 

[Brian Lawrence]

Ok I see them now I was looking on the control board

 

[Johnwa]

I’m in Oakridge, south of the Glenmore reservoir.
Do you have Grbl on the Arduino and what software are you using on the computer?
I’ll set up a the same configuration and see what happens

 

[Brian Lawrence]

I can always bring a box of parts to where ever you are as well.

 

[Brian Lawrence]

I have grbl controller on the XP, as well as Mach3, EFL CNCH as for being on the board not sure. It could very well be the software issue, again I'm not overly familiar with.

 

[Brian Lawrence]

We might be able to do this over a phone call if its just a software issue

 

[Johnwa]

I’ll set up eflcnc/Grbl. Might not get it done today tho. If I get it going then we can talk/meet up.

 

[Brian Lawrence]

I thank you for your continuing help.

 

[Johnwa]

Brian
How did you flash Grbl onto the Arduino board? Can you get EFL to connect to it?

 

[Brian Lawrence]

I don't know if I have flashed anything as of yet

 

[Brian Lawrence]

EFL will not connect

 

[Johnwa]

Ok. Download this file
http://cdn1.inventables.com/hexfiles/grbl/inventables_grbl_09j_2015_07_17.hex

Then open it EFL. You will have to tell it to open all files, otherwise it only shows .nc files.
Then with your arduino connected to the computer click the upload grbl button. You might have to select a different comm port from the list just below the browse button.

You should now be able to connect to the arduino and connected button will light up.

The hex file is not the latest version of grbl. There is a different method to upload the last version but lets give this a try first.

 

[Brian Lawrence]

it comes back with a Read COM port error

 

[Johnwa]

You will have to change the comm port in the box just below the browse button in EFL. You’ll likely have to open up device manager to identify the port.

 

[Brian Lawrence]

Well it seems I am as stupid as I look.
John had things figured out pretty quickly. Apparently Grbl had not downloaded properly, amongst other trivial things.
Well I'm happy to report that John got me running well at least until to the next problem, but I'm pretty sure I have a lot to learn now.

Give John a little (and I mean a little) nudge on the arm, or an Atta a boy, Job well done.

Thanks for helping me John.
Oh and Alex as well for helping me as well.
