High speed spindle for Sieg X1

[John S]

Anyway, enough dick play! We all want to see your list of 6040 improvements, costs and test results:clap:

Can't really answer that question as I have never seen one in the flesh, from all the Ebay pictures i have seen the build looks OK provided they have fastened everything up square and free.
What they don't show you is the control box internals but I reckon that if you cost out for a complete new box, transformer, cap, bridge rectifier, 3 drives and possibly a new breakout board you will have a bomb proof system.

I'm a big believer in having spare capacity and have found out that on the smaller motors that need 3 or 4 amps if you get the bigger 80 volt 7.8 amp drives and run them de-rated, they never get hot, never break down and fly.

Ok more expense but how much does a ruined job or having to mess with a machine when you are supposed to be earning really cost ?

If you know this figure needs to be costed in whether or not you go for it on day 1 is another point.

Agreed 100%, this applies to most things and not just steppers.

The problem is convincing the customer that the additional money is well spent, especially in a consumer product which is essentially what these Chinese routers are. Eg. Build a router with good electronics, it costs an extra 10% and some will gladly pay for the additional robustness, reliability and utility. My router design costs less and word gets around the internet that the controller is a bit dodgy but if it causes a problem then the cost of replacement is not so high and phrases like 'learning experience' are used to justify the gamble. I sell a shit load. Next thing you know, the manufacturer of the 'good' router has a cost reduced 'light' version for sale - they need it to stay in business. The sad part is that now the world + dog believe that this is the way routers should be. The up side is that many more people at least have the chance of getting their feet wet in the world of routers.

I'm lucky enough to have a full controller set-up, it will be fascinating to hear how the mechanics of these routers hold up.
