Hi. all. Just got a 6040 Chinese machine. Set up the mach 3 software. Input all settings from online manufacturer. Machine runs great. But the size of the job was miniscule. so small it was tiny on the screen. Checked Func 6 and did calc re travel. specified a figure and machine moved that distance. Have no idea how it happened but at some point the image on the screen changed to the proper size and the job cut out perfectly. Saved the settings and turned Mach 3 off and reloaded the program. Back to the original Tiny image and the machine doing the tiny movements again. I have no clue what is going wrong!!! Anybody know please.? It's doing my head in!!! Regards to all ....Ronnie.

Have you got the native units set to Inch or MM

Hi. They are set to MM.

Just thought I may have changed them to inch. Can not check now because i'm away from the machine. I'll check when I get home.

Hi. Graham. Yes just checked. Native units set to MM. Tried changing to INCH and restarted the computer just to see what happens. Loaded the file and same result. Tiny. One thing also. When it is like this the XYZ movement figures are large increments for a small movement of the travel.

 you will most likely have to recalibrate the axis. also how did you go about changing the units? there is a right way and a wrong way.

Hi.Charlie. I just went to the native units page and clicked either the Inch or MM. I did try rebooting the computer and reloading Mach 3. What I can't understand is how suddenly the size of the file transformed into the correct size and I'm pretty sure i did not do anything at that moment to make it happen. I then ran the job and the machine cut it out perfectly. I then hit save in Mach 3 and rebooted the computer. When Mach 3 loaded the problem was back!!!

It might be mach3. What version are you running?

Hi. Charlie. Well. On the disk supplied with the machine by the Chinese seller when opening the file it reads Version R3.041. But when Mach 3 opens the opening briefly showing page.{top R/H corner} says 2.0 so who knows. Also I noticed it also shows XP and 2000. I'm running the machine in windows 7 and it is a usb connection. The machine was sold as XP or Windows 7 capable.. But the program as I said did display my image and ran perfectly that one time so I'm assuming it is a parameter that I have incorrectly done causing the problem. Regards...Ronnie

Hi Ronnie,
 I also have a 6040. It came with that same version. .062 was the last best version. I would update to this version.
