His program has a G91.1 in it, also D1 is global as far as I know.

Hi Salty72,

sorry could not get back sooner, I had a busy one yesterday.

Try this new and improved version (sounds like washing powder ad).

I think it rhymes with Clucking Bell.

Its 2:30 am here, I will be back tomorrow, email me all your latest files.

Having looked closer at your code the profile is dodgy, see picture

Hi Salty72,

My theory is this :-

based on the code you posted the longest single move in the file is approx 0.9mm, if your router is running at even 20% of 2600mm/min this is still 520mm/min how on earth can your axis drives possibly get any where near that speed and back to 0 in .9mm moves.

If you add up the total distance to travel its only 250mm so at 200mm/min its only going to take 75 seconds.

So 1min 43 secs at 4600mm/min ain't right.

I have 2 machines on the same job 1 rapids at 40 meters/min the other rapids at 10 meters/min over short moves the 10 metre machine is faster.

Hi Salty,

This may sound daft but drop the feed rate down to 200mm/min and see how that cuts, it should cut sweet.

Chances are it will cut it just as quick.

I would stay away from the guys that made the Hubble one.

You could use a second parallel port or a Mod IO card form Peter Homann,  then its just a case of writing a bit of code to set the outputs and pulse the PLC.

This can be done in the M6Start macro.

The PLC software first reads the inputs and changes the tool. When its finished it can set the output.

Then Machs M6end macro waits for the finish command.
