Ok at the risk of people laughing at my programing skills, here is a simple program I used to machine the cab side of my steam loco. Its in imperial so have a look. Put it in your machine and see if it cuts in imperial. If it does its something to do with the link from Vcarve'
I'm in the UK so way past my bed time will look in the morning to see your reply. Good luck.
PS you might need to change the tool number to make it work round the corners, say 6mm and please note its over 16" long

Hi Mark, OK I'm a basic CNC man and all my programs start by defining the measurements, cancelling any offset to clear the machines and Mach memory from previous jobs. Not sure about your V carve but its probably doing it in metric so 8% full size. I would have thought the machine wants to know somewhere at the start what units its cutting in G20 is imperial and G21 metric. If you try putting in a G20 be careful as it might go sailing of over the stops. Keep one hand on the emergency stop.

Have a look at the code for the metric/imperial. If it hasen't got a code at the start of the program file it might do it in metric so your 1" cut might only move 1mm? I had the same so if there is no code for the G20 or G21 it does the component in the scale the machine was set up in. just a thought

Sorry forgot to say look in config tab at the top of the MACH page, then its the forth command down. Be prepared for it to not solve your problem, it didn't solve mine it was a problem with the electronics. If it doesn't work put them back on.

General config page on the right, about a third down, untick the box

Hi Gary, time to throw in my four peneth in. Why cant you use the axis setting option on the setting page of Mach. Its in the bottom left hand corner of the page and providing you can measure the distance your axis have moved it will set the steps for you. I did this and it gave me my setting which I rounded up. I think mine gave me 799.9 so I set it to 800. Jim

H Gary glad to hear your nearly there. Not sure what your 4 axis is trying to do, mine is for a rotary table so has its own settings and output pins. I can unplug it and take it off the table. What are you trying to do with yours. Jim

Thank God for that, half an hour before series 10 episode 11 is to be viewed on British TV for the first time. Keep us posted on your progression and don't hesitate to ask (about your machine set up not what happened in NCIS). Jim

No, one the end of the line where you assigned your pins for the x,y and z axis. It asks something like port dir and something else, you should have 1 in them for each axis. Jim
