Digital display settings changed and not sure how to get it back!

Hi,

I have an M-DRO BC10-3M

Recently I inadvertently pressed a button (don't know which!) that has make it practically unusable.

Previously if I moved my mill bed say 50 mm, the screen would show that I had moved 50.000mm

Now it seems as if the decimal point has changed and I cannot make any sense of it.

I have recorded what I am seeing in the attached video.

The video is showing the BC10 setup in mm; I move my mill bed 25.4mm (1inch) and the screen shows it move from 0 through to 9999 twice and then ends up at 4877 on the third 'loop'.

Here is a link to the video: UXvDp3VT1LvZWFPS8 >**LINK**

Previously it would have just shown, 25.400 as the end value.

I cannot find manuals on the web for this or any support. Does anyone have any ideas!? Anything might help point me in the right direction. I am completely stumped! I spent 1.5 hours trying to decipher what we are seeing with a friend.... but we are non the wiser!

Thanks!

Wayne.

Sounds like the resolution of the scale has been altered but don't have that model to confirm. Had that on another forum a few weeks ago but their decimal point only moved one place.

Also in the video you say you are going to move the table one inch but you say you are going to turn the handwheel once? I would expect 10 turns on an imperial machine and 12.7 turns on a metric machine.

Hi All, gosh, thanks for the various rapid responses!

@JasonB - you are absolutely right - sorry being a novice, I didn't think that one through when making the statement! I haven't checked - but I am sure you are right.

@Dennis - thank you - if I can't get it right with Geoff's kind offer of a manual - I will definitely reach out to the Allendale group. Great to know they are good on customer service.

@Geoff - thank you - very kind offer. I will PM you details.

Like Jason, I think the resolution has been set wrong, ie a mismatch between the scale and the display. Wayne's unit may be showing actual scale counts rather than converting them to inches or mm.

The DRO has to be told what the resolution of the connected scale is. To do this it has a hidden set-up function and the problem is finding out how to activate it. I hope Geoff's manual will explain! Various methods: button on the back, or a computer connected via a USB port, but more likely a particular button on the front panel is pressed at the right moment whilst the unit is powering up.

This video is for a different unit, but it shows a typical set-up approach used by many electronic displays, not just DROs.

M-DRO seem to be one of those pesky vendors who fail to publish manuals on the web. They do have a nice line in videos (see above), but Wayne's question is hard to answer without the proper documentation.
