I decided to make my 'home built' 4th Axis portable between machines so constructed a 'stand alone' controller which connects to the LPT3 port. Drilling a few more holes into the table of my router has enabled it to be fitted quite easily (fitting holes have also been drilled for the mating tail-stock but this is not required for eggs  ).
I made another Jacko egg and thought you might like to see the setup.

Perhaps a daft suggestion but could you not PM Darek http://www.machsupport.com/forum/index.php?action=pm;sa=send;u=257 and seek his advice.

Great work Dave, building up the Brownie points eh.

Good point Derek.
Perhaps we should have a competition ?.

This little chappie (code courtesy of Kent) runs into more than 342,000 lines.

This is the official line.

'Mach3 has a limit of 10,000,000 lines of Gcode even after licensing'.

No worries. 

Glad you got the problem sorted. Looking forward to seeing some pics of the things you make with your new machine.

General Mach Discussion / Re: Combining grounds of 12VDC logic and linear unregulated HV

« on: May 18, 2010, 06:01:33 AM »

It is indeed that simple.

If you connect the minus end(-) of your HV supply to ground then the other wire will be +72 Volts with respect to ground.

If you were to connect the plus end(+) of your HV supply to ground then the other wire will be -72 Volts with respect to ground.

Typically, PS schematics show DC+ and DC- output. So my assumption is that with a linear unregulated PS, the DC is split into half positive and half negative? i.e. with a 72V output, is it +36 and -36?

Do you have a center tap on the psu output then ?. (3 wires)

If it is just a 2 wire output - then connecting the minus end to ground will make it 0 Volts and the other end will be +72 Volts. There will be no negative voltage levels.
