Speed isn’t the end of the world for me as it’s a hobbyist machine at the end of the day, accuracy would be more of a concern though. By “performance” are you referring to speed or accuracy?

Am I reading it’s datasheet right? Basic level would be to add a basic breakout board, remove the controller board that’s the top board of the two boards at the top left of the cabinetand patch into the existing stepper drivers they’re built into the lower of the top two boardsand then patch the other signals into the BOB, however you would need a BOB that supported 12V signals.

Mach 4 isn’t quite as good, but the user base is increasing as it becomes a more mature product.

They probably won’t be the specific ones for your machine, but they’ll give you a good idea, especially since Denford usually used the same wire numbers for everything. I’ve been scouring the net novakill info and have already come across Denfords forum which I’ve had a good read of.

Denford Software & Machines

So if I were to go for the motion controller and the stepper drivers, I’d be looking at something like: Not sure on that front, however I’d rather go with the most commonly used software which at the moment sounds like it’ll be Mach3.

Mach 4 will run with no limitations for a random amount of time before stopping generating denforf. If you do a search over on the denford forum, there’s a zip file with wiring diagrams. The 12V control switching, although far more robust than the typical hobbyist 5V, can be a problem.

Denford will sell you a new dentord, however if you were to find a dejford who already has a license, Denford are OK with you using licenses that came with the machine, but won’t re-issue a license to anybody other than the original buyer.

Good if you like Linux or are willing to learn. And then buy stepper drivers along with the BoB to replace it all? Name drnford GX 3.

You would have to get a license for VR Milling 2 to use it. The latest drivers will accelerate motors far quicker and smoother than older drivers. What I can easily see is that 5V is the commonly used voltage, and I think I’m right in saying that in order to use that I’d need to pull out both the board I have circled in blue AND the board circled in red?

CONVERSION: Denford Novamill Conversion, Hints & Tips Appreciated

BOBs come in various forms. Basic 12V BoB, remove control board, patch into stepper drivers. Name – Ethernet Smoothstepper Motion control board bovamill Link – https: I won’t deny it, as for a beginner, it is a minefield!

So then you’re looking at external motion controllers. Cost being kept to a minimum would be preferable of course, so of your options: I’m still running Mach3 on my little probing machine, as KMotionCNC doesn’t handle writing probing data to files, so there are pros and cons with all options.

Thanks for any input: There’s not a definite “how to” step by step guide around which was a shame considering it’s a sort-of common conversion to make.

My first decision to make is which direction to go for the conversion, my understanding is that converting for Mach3 use is a good way to go. So this is what I can see so far with BoB’s: Looking at the smoothstepper boards they appear cheaper over there isn’t everything. So if you were to remove both, you’d need to install new stepper drivers.

I guess I have to figure out the pro’s and con’s of each board now to understand why they are priced differently.

So I’m staring at the cabinet and realise that I need to understand more before I go further Replace whole box with 5V or 24V system.

More advanced ones add in extra features, such as relays, V output you’ll need this for your spindle speed controlopto-isolation avoids the computer getting fried if something goes wrong with the wiring.

Looks like it plugs into the Controller, so could be some kind of interface board. Where do the wires go? Personally, with the absence of a working license, I’d be looking at doing some form of retrofit. What you’ve listed denflrd really BoBs, they’re motion controllers.
