Bit of a long story - go get a coffee and also bit of a history lesson but it get to the point of the post.
My involvement with CNC came in 1994 when I went to an auction just to see how much large [ 50" + tables ] were going for and came away with a mint Beaver NC5 for absolute peanuts because like a lot of early machines it had broken rubbish electronics.
With some help we did actually get it running on the original Posidata controller. I had looked at doing a manual conversion so knew the marketplace as regards controllers etc of which where wasn't the choice we had today. First couple of jobs paid for an upgrade and we chose an American company with a very good UK agent called Ahha, I know silly name but so is Apple. Old Dos program, needed a dedicated card in the machine and the card and breakout board which was made to plug into the Posidata was £1,800.
Absolute brilliant bit of gear, in fact it's still on this today and a Bridgeport MDI BOSS is also on one. I could convert to Mach but to be honest it wouldn't give me anything I don't already have except perhaps wizards.
This lead to buying up cheap machines, converting them and selling them, there was a market and I had access to heavy lifting gear with Hiab trucks etc, this slowly fizzled out as companies got rid of older equipment and upgraded to VMC's.
About this time the small hobby market was developing and starting to convert to CNC. There was a range made by SimplyCNC up in Scotland based on the X3 and articles like Dick Stevens in MEW helped this but I felt I could do a better job and so approached Ketan at Arc Euro to do a kit for the X3.
First problem we got was cost, Dicks was cheap because he's done all the work himself, something a lot of people seem to miss. SimplyCNC was more expensive but he'd cut corners that much to get the price down that it was unreliable and caused him to stop doing these with a bit of bad press as well.
I was ready to throw the towel in because we couldn't get an affordable conversion using good components but Ketan said carry on and we will review final figures and ask round. It soon became clear that there was a market for a decent conversion and we went ahead. You got everything to bolt on and all the electronics to built the rest, you had to do all the fitting but it had a very good book to explain everything.
That book was the secret.
The first book was written and given to a guy who had no experience of CNC but was a decent engineer. Two pages in he was stumped because I'd missed an obvious move out, obvious to me but not a beginner. It took 10 re-writes to get the book done, by this time we were onto a third guys as numbers 1 and 2 now had some knowledge and we didn't want that.
It was a total success and we sold just under 40 kits, even sold one to an 82 year old guy and he got it running.
Then the Chinese came on the scene directly and asked, would we help them develop a turnkey CNC WTF, no way that's our bowl of rice.
Then on second thoughts if we don't someone else will and we will be out the loop.
So flew to China, thrashed out a deal, came back and built the KX1 CNC here in the UK, bits and plans went back to China and the KX1, KX3 range was developed which then got ripped off by Novacon, Syil and the rest.
Part of the deal was we would write to operating manual here in the UK, no Chinglish, given our previous experience with the X3 manual and we would support world wide sales of these machines via a web based site.
World wide covers everything except some Asian countries which are handled by Sieg and Russia who have their own arrangements. There are many of these machines in schools in Russia.
So today we are supporting many countries with these machines. Majority go to absolute beginners who have never used a CNC or even a milling machine and there is a lot of hand holding.
The ONLY way this model works is that it uses Mach on the Windows operating system, 90% + of our web based problems are computer / program related, the machines are very reliable given the number of them out there.
Most users with problems can sort there own out with a bit of help once given a start because they are familiar with windows, note I said familiar and not experienced.
Given our user base, beginners, if we had made the move to Linux and EMC this model would not have worked for the sole reason they are not familiar with it.
EMC has a place, no one is saying it's better or worse but it's not for the great unwashed out there.
Thank you for letting me explain our model.John S -
