Hi

Further to my CNC quest this board has been so helpful with so far, I have seen some old posts here as well as the Model Engineer article about converting the WM18 to CNC.

The 4-axis + high speed motor job Roger has done looks amazing, but there are no plans or drawings as such. Not a criticism by any means and as he points out, setups vary and he figured it out on the fly.

However being slightly time-poor, I was wondering if anyone knows of a source of plans / CAD models etc for converting the current WM18 model, or very close equivalent, assuming changes have been made over the years?

One older post here mentions needing to machine something for clearance, I am hopeful that is not still the case as I also have a concern that extensive modification will void warranty. I know some drilling will be needed for limit switches and such but I would like to avoid major surgery!

Thanks for reading

There is a company in America that produce a Kit of the mechanical parts for a similar milling machine (The GRIZZLY G0704), that might be worth a look as they have instuctions on the fittting of the kit, on this page:- **LINK**

Also a lot of information on converting the G0704 around and so probably best serching for this machine, as well as the Warco WM 18.

I would have thought that any warranty would be void if you converted to CNC. Surely a warranty only has any value with the electrics and motor and presumably you would be replacing those anyway.

Hi Nick, thanks for the reply. I have looked into that machine and numerous videos of the conversion, and whilst it is similar, it appears to be the equivalent of the WM16, one model smaller than mine. Though the general idea will be the same, obviously the kit parts would not match. Thank you for the suggestion though.

Thanks Andrew,

When I spoke with Warco, they said it would void the warranty only if I made extensive material changes to the machine. That is why I am asking about the potential need to mill off metal for clearance (I am not sure on which part) which was apparently needed in the old versions of the WM18.

Cheers

From what I can understand there's a clearance issue to fit the table new lead screw.

There is an Amadeal milling machine just advertised on the homeworkshop site for £400.

It's worth noting that it is possible to get smaller ballscrews if you look around. I believe that the Myford lathe conversion kit from "cncyourmyford.com" for example uses an 8mm dia screw on the cross slide because the standard bore in the Xslide casting won't accommodate anything bigger. They are harder to find and more expensive but may save a lot of grief modifying castings. You will also need to make sure the screw is under tension to avoid it bowing.
