Hood,

So the Scorpion works with Mach3? With the Scorpion you are using one network card, what did you need the second one for? Do you have your PC connected to a network?

Where are you getting those panel buttons from?

Hood,

It looks good! And certainly each machine you do gets better Smiley

A few questions:

I know a Smooth Stepper must be in there, but can't see it...?

Also, since you have all those buttons and particularly the FRO and SRO pots, I would assume a Pokeys should be in there, but can't see that one either.

Could you explain what are the buttons on the first raw at the top? SpinEn looks like enabling the spindle drive, but I would expect a On/Off switch and this looks like a momentary switch? And the other two, just curious what are they (Limit and Control)?

Oh... and does Russ sell those relay boards? Where can I acquire one?

Roger,

While making a worm wheel with a tap like some do will transfer the movement, it shouldn't be considered for efficiency critical or, more importantly, for high load transmission applications. The tooth profile is not thick enough to carry high loads and the helix would be probably too small leading to reduced efficiency. There are many other considerations as well to this.

The Arduino does look very capable and flexible indeed, but it's a bit like reinventing the wheel when trying to achieve with it what the Pokeys already does and is specifically designed for.

Ah... OK Hood Smiley Just thought you found a way to somehow incorporate it on your BOB, but looks like you'd still run another (serial?) cable to your PC. So still looks like a Pokeys is a better way to go.

Brett has recently been messing around with the Arduino and we are thinking of incorporating it into a BOB for analogues and maybe a few other things.

Hood,

But you can't establish the communication between the Arduino and Mach over the ESS. So you'd need to connect a cable direct from the Arduino to the PC. Or am I wrong?

What advantages does it give you over a Pokeys?

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!
