M-DRO MDC 700L set up

I have a stupid question about the DRO on my lathe. It's likely to be basic set up but I don't have the instructions!

It is a M-DRO MDC700L

I'm re-fitting the X axis components but this time doing it properly so that the bracket holding the X axis sensor doesn't interfere with other moving parts.

I think I worked out how to do it without drilling anymore holes, then mocked it up prior to machining a new bracket but the readout is in reverse, that is, as cross slide moves towards the work piece, the readout on the DRO goes up rather than down.

What am I doing wrong?

Thanks, Gavin.

Hi Gavin

I have the mill version of this DRO but the setup looks to be universal. When you switch it on you'll see the linear resolution on the display, I think mine says "LIN-5" or similar. Press Enter to get into the setup (you only get a few seconds). You can then scroll through the various options using the arrow buttons and should find DIRECT and there'll be a 0 or 1 in the X and Y values (and Z if you're lucky). The book does describe the conventional setting quite well but doesn't say which is 1 and which is 0. Rather oddly, you press X and Y to toggle the values rather than 0 or 1.

I just had to change the settings on my mill to get things to work as per the book.

If you drop me a PM I'll try to scan the manual to PDF for you

Hope this helps, Chris

Thanks Chris, that worked a treat!. I don't think I'd have found that by trail and error in a month of Sundays, though I've no idea how I managed to reverse the settings in the first place!

I have messaged you with my email.

Just a quick public thanks to Chris who, as well as the advice above, has sent me a scanned copy of the manual this morning
