Switching From Inch to MM

Greetings,

Recently fixing my JOG concern, I now discover that when I apply G21 via MDI, the JOG values still move in inch increments.

That is, clicking on 0.1 moves X 2.54mm.

Do I need a separate Axis configuration to put the machine in MM mode?

In summary, how do I JOG 10.0mm, 1.0mm, 0.1mm, 0.01mm, 0.001mm?

With kind regards,

David

Greetings,

I may have it sorted. I modified the INCREMENTS line...

INCREMENTS = .1in .05in .01in .005in .001in .0005in .0001in 1mm 0.1mm 0.01mm 0.001mm

The machine now JOGS in either inch or mm as selected from the drop down menu.

However, the Rotary Axis moves better with the INCH increments. That is, 0.1in selected will move A-axis 0.1 degree. If you select 1mm increment, A-axis moves 0.0394 degrees. 0.1mm=0.0039, 0.01mm=0.0004. Ten clicks of 0.001mm and A shows 0.0004.

From the manual...

INCREMENTS = 1 mm, .5 in, … - Defines the increments available for incremental jogs. The INCREMENTS can be used to override the default. The values can be decimal numbers (e.g., 0.1000) or fractional numbers (e.g., 1/16), optionally followed by a unit (cm, mm, um, inch, in or mil). If a unit is not specified the machine unit is assumed. Metric and imperial distances may be mixed: INCREMENTS = 1 inch, 1 mil, 1 cm, 1 mm, 1 um is a valid entry.

Makes me wonder if angular values can be used. It would make the drop down box rather busy, however.

Again, many thanks to all that have come to my aid. I am actually machining parts now and very pleased with the results.

Sincerely,

I think you could add in unit less entry's in the increment to get you pure degrees for the A axis. So you could have 0.1in, 0.1mm, 0.1, etc.

Greetings Nitro,

I tried removing all the "in" "mm" suffixes and the machine moves based on what the default system, Inch or Metric, is.

Cheers,

Dave

Yes that is the way it works without units. But what that means is that if you select a unit less jog when jogging the "A "axis it will move in the default unit system of degrees for the "A" axis.

You would still need to select 0.1in to jog in inches or 0.1mm to jog in mm for the X,Y,Z axis.
