cnc 3040 and mach3 problems

[JAZZCNC]

Eddy The road runner is not small it's quite large it's just using imperial units and you have tried to cut it with Metric units so appears small.

This will most likely be the problem here.
If you want to use Imperial units then Go to Config menu and Native units and see if it's set to Metric units.?
If so then you'll need to change and restart Mach3.
Then go into Motor tuning and change the steps per. What ever is entered in steps per just multiple by 25.4.

If you just want to see the road runner cut larger but don't want to change the units then just use the Scale Axis feature and type 25.4 in each axis Scale Dro.
You'll find this at the side of the Green DRO box with coordinates in it. Click in it and type 25.4 and push enter, you must push enter or doesn't happen.

WARNING Doing this remember to reset the Scale factor to 1 before cutting other parts or every thing will be sacled 25.4 times.!! . . .Thats why it will flash yellow to warn you.!

To be honest I don't think you have enough room to cut the road runner full size on 3040 so just set the sacle factor to say 5x and that will make it big enough to see cut.
