Buget Warco Major 5 axis conversion

Tweaky, Drop the speed down a load, it's not a race and reliability is worth more than speed over such a short bed length,
If you know it does 5250mm min, halving it will give you a 100% safety factor.
Set the velocity in Mach to 2500.

Hi John, thanks for your coments.
Should I increase the resolution, which will also decrease the top speed?

[Tweaky]

I should add that whilst setting up, I set Mach3 to 45Khz, turned up the PSU to 40v and it ran hapily at 6000mm/min, so I thought I had some margin already.

If you are happy at that then fine but 6 metres a minute over a bed length of this size doesn't give you much time to hit the E-stop.
Another point is that Mach is more happy at lower kernel speeds less chance of errors and the base 25K is plenty for mills etc.

The high speeds were brought in for routers and such with servo motors that require 2,000 to 4,000 steps per rev against steppers at 200 steps [ in full steps ] these were running out of steam.

You don't really achieve much on stepper driven machines as the stepper drivers are the choke point and get egg bound way before the set maximum.

[Tweaky]

You are quite right, it leaves no time to hit the Estop, in fact whilst playing I found that the limit switch had to be set to be nearly 25mm inside the EOT to enable it to stop before *!?
Cheers

Here is my box for the electonics (ex alarm box from a skip). It is not tidy yet because I am still sorting it out.

and here is the Y axis limit switch.
