[Clive S]

Hi iv'e been looking at that video link you sent me and it is very informative and helpfull so thank you for that. As far as the DRO is concerned if i set the depth of say 1mm on the DRO screen yes it doe's show the -1mm. Here is an image of the GCS in use with a Coke sign which i'm working on.
G-CODE CNC BACKUP.txt This on is the setting of my cnc as followed per instructions of that tutorial video you showed me.
I hope this helps , i'm not sure on all the termanoligybut ill get there.
Thaqnk you freind Colin

Colin as I have said there is no point in trying to cut anything until the parameters are set correctly.

Now concentrate on the Z axis only .

Find a block of wood about 50mm thick put this on the table and Zero the Z on the top of it.

Then move the block out of the way and command the Z to go down 1mm the DRO should read -1

Then measure arcuately how far the Z travelled down from the top of the block and report back.

This is the line in your text file you posted that we will alter to get it right $102 = 1900.000 (Z-axis travel resolution, step/mm)
