you should be able to connect this with a 5 volt supply and connect it straight to the breakout board.

Or have a look at these, these work even better

Certain DRO's are read only, I think that is one of them.

That reminds me of the lady who loved Robert Redford and adored Burt Reynolds.  To show her love for them she had a big letter R tattooed on her left butt cheek and a big letter B on the right.

When she bent over to show people, they asked, who's RoB ?

Yes, that should not be a problem. Mach3 runs pretty much ISO g-code so will run code from most CAM systems.

If you look in the downloads section at the top of the site you will find a Mach3 Mastercam post processor for version 9.

Hi,

Denford still upgrade these so no public domain data is available, you can get it updated or because it has a DenStep controller, you will have to remove the controller and fit new drives a breakout board and spindle controller.

Its not a big problem, many here can help you.

It depends on the type of controller that is/was fitted as to what needs to be done, it is possible to control the machines, if you can give us more details about what is in the control boxes, post some photos too as that helps.

So if the smallest rad is .25 then the largest cutter must be .4999 or smaller. A .5 cuter with a comp of .25 wont work as its equal to the smallest arc. Very limiting as code with .125 inside arcs almost cant be cut now.

so what is wrong with using a 6mm (.236") cutter

I think Brian is a bit punch drunk with programming code so let me try to clarify this.

Rule 1.

You can not apply or cancel cutter comp on a G02 or a G03 command :-

e.g.

G01 G42 P2.5 X20. is legal code

G02 G42 P2.5 X20. Y0 R10. is NOT

Rule 2.

The lead in and lead out lines must be longer than the rad of the cutter, so if you are using a .5" diameter cutter the lead lines must be longer than .25", the general rule is 1.5 X radius of cutter.

Rule 3.

You can not use a cutter larger than the smallest internal diameter, if your smallest rad is .25" then the largest cutter you can use is .4999" diameter.

Rule 4.

G20, G21, G28, G28.1, G30, G31 and G52 can NOT be used with in a block of comp code, e.g. these g-codes must not be used between G41/42 and the G40

Rule 5.

You can NOT have 50 consecutive lines of code without a movement command, e.g. X,Y

A line is 1 or more blocks terminated by a return

I hope this clears the confusion.
