Thanks for clearing that up. It makes sense now. I thought it was odd that they would leave drivers out of the graphic.

Yes, you would bypass the NM200's BOB. The wiring from the drives, and the other input and output wiring going to and from the BOB would be connected to the Acorn board.
There is at least one...
The graphic on the Acorn page at the Centroid website doesn't show the drivers between the board and the stepper/servo motors. This could lead one to infer that the board replaces the drivers. It...
Though it may not be completely accurate, I think of the Acorn board as a combination ESS and BOB. The Acorn has an on board CPU which handles motion control. Like the ESS it takes a load off of the...
Thanks for posting your setup. I’m considering something similar for my machine.

Here is why I’m going the Centroid Acorn route and a few of the draw backs I see:
My experience with Mach3 was mixed at best. I thought adding in an ESS would help. It didn’t. I’ve been following...
Just a heads up for anyone considering the Centroid Acorn controller and software. Their introductory pricing ends Jan. 3rd 2018. Here is a link with more information. End to Acorn Introductory...
Thanks for the input. I'm having similar random e-stop problems.

brianbonedoc, did you finally get the random E-stop problem resolved? If so which fix or combination of fixes worked for you?
CJ
Thanks Eric. Glad the board worked for you.

I've retrofitted my NM 145 mill. You are welcome to the boards and spindle motor for that matter if you can use them. PM me.

hjl4,
Thanks for your help, I appreciate it.

Thanks for the reply. I would consider the wires from BOB to drivers, BOB to VFD (analog input), and the proximity sensors to BOB as signal wires. I already have shielded Ethernet cable between the...
Hi All,
I'm rebuilding my Novakon NM145 mill, swapping out the original motor and VFD for an AC induction motor and appropriate VFD. I'm moving the electronics cabinet from the back of the mill to...
Ray,
Thanks for your input. Interesting idea adding in the missing components on the board. Any idea what the three pins labeled PCI, PCO, GND are for? They are located just to the right and below...
T300,
It is a late model NM-145. One of the closeout machines purchased in the late winter of 2012.
Ray,
Thanks for your input. That's an interesting possibility, adding the missing pieces to...
Looks like the Homann DC-05 DigiSpeed MC board would do the trick. Thanks for pointing me in that direction Ray.
I'm still interested in obtaining the information indicated in my original post....
Thanks for the input Ray. That hadn't occurred to me.

I'm in the process of converting my NM-145 from the factory VFD and spindle motor to a three phase AC induction motor and appropriate VFD using the Shadowspawn LLC retrofit kit. My NM-145 came with a...
Thanks for the responses to my queries. I appreciate the information.
Curtis
I've read a lot about the Ethernet Smooth Stepper and in general it gets high marks. For those of you who have been using the ESS are there any persistent bugs or negative aspects that you've...
Zero_divide,
I installed the latest version over the previous with no problems. Running 64 bit version of Windows 7 . Thanks so much for all the work you've done putting this useful tool together...
Which motor and VFD did you purchase Charlie?
Please keep the photos coming. It helps me greatly to understand the procedures involved and the relationship of the various parts to each other. Being a new owner of an NM-145 your hard work is...
toddp and t300,
I've attached two zipped .xml files. The NM-145 file is the one Khai sent me for my machine. It is titled "New Circuit Board Test 2012 Jan". the NM-145B file is the one overrev...

overrev,
I sent you a PM
Thanks Bob! I didn't notice how old your original post was. Nothing like ressurecting the dead.
Curtis
I emailed Khai last night, 8:30 my time 10:30 his time, and got a reply back almost immediately. I'd recommended contacting him via email. He has always been very prompt in responding.
