Title: Changing DRO
Post by: sward on March 15, 2011, 06:22:19 AM

Hi,
  I am new to all this so any help would be appreciated. How do you change the X, Y and Z DRO to show English measurements instead of Metric.  Our company just purchased a Vortech Router that came with the Mach3 software but I haven't found anything in the information or tutorials to help me with this

Under Config/Set native Units, set this to INCH if you primarily use Imperial units.
Then all code that includes G20 at the start will show in INCHES and G21 will show in MM.
Or, MDI G20, G21 to toggle between the two.

You should really go through the Mach3 Install manual section 5.4 especially as ther are other settings associated with this. Motor tuning for one.
The manual is under the Support link at the top of this page.

If you machine is set native units in metric  and you change the native units to Inch you will have to multiply the steps per unit in motor tuning by 25.4 and divide the Velocity and Accel by the same amount.

You can Lock the DRO's to you setup units on the General Config page also.
Then any code you load will show as setup units.
