I am then thinking of making a 24v I/O board for ports 2 and 3, probably one will have a couple of analogue ins for FRO and SRO.

How are you going to handle the analogue inputs?

Heres a pic of the one I made for the scorpion, works out fairly expensive getting pcb's done in small numbers

Still cheaper than isolation routing them yourself?

Hood,

You might want to check this line driver out:

http://search.digikey.com/us/en/products/CUI-102E-10/102-1787-ND/1923401

It is designed to be used with AMT encoders, but no reason you can't use it to drive your servos.

Amazing work there on your new mill, Steve!

I have been thinking of using a 4th axis as a tool grinder for some time now. Nice to see you actually doing it and getting good results. Gives good motivation.

You're videos are very professionally made as always and a pleasure to watch. Thanks for showing!

Hi Gerry,

I am only sure I remember Art or Brian mentioning it, but whether it's really the way it works I don't know.

Regarding Sherline mode, I am sure about it, as half the cycle time at 25Khz kernel is 20uSec Wink

Hi Michael,

The values entered in those fields is the amount of time to be added to the standard pulse width (around 3uSec). So if you enter 5 there you will get an 8uSec pulse width. I think it is only true for the step pulse, the direction signal being just a change of state, but am not sure about this as some time ago someone was reporting a different behaviour (although with SmoothStepper) which was never confirmed by other users.

 If you need a wider pulse than that then use Sherline Mode (under Ports and Pins), which will give you around 20uSec pulse width.

Check what your increment step is set to. It may be set to a large value (e.g. 1mm) and your feedrate is set very slow so you're seeing it doing that large increment at a very slow feed.

If you program for the tool centre then you need to compensate for its radius.

I think your problem is in the X start position:

G0 x.12 y0.0

Change that to:

G0 x0 y0

And you should get a 1" hole with:

G3 I-.25 J0

Hi Wes,

Something I had forgotten to mention before I started this run of parts - would you consider adding a parts counter DRO? Should be fairly simple and you already have a macropump anyway so will only have to look at the Cycle button being activated and count it.

Another thing which may not be that simple is a total elapsed time DRO (from the moment Mach loads). It has to be zero-able. Together with the part counter it can be a very valuable tool for high volume runs.
