SINO SDS2L DRO Problem?

Hi All,

I am in the process of fitting a SINO SDS2l DRO to my ML7 and have so far installed the long scale and read head at the back where the taper attachemnt would go. I have clocked the installation and bracketry and all seems good.

When I connected the scale to the display and fired it up it went through its startup and seemed to work OK....

Until I pressed the X button to zero the scale when all I got was a decimal point.

No matter what I do I cannot get a row of zeros to come up.

I have swithced the axies and taken a couple of pics, first an arbitrary position then after hitting Z/Zo, just the decimal point.

Have tried all sorts of scrolling throught the ABS & INC modes but no go.

Any thoughts please or have I bought a pup?

I'm not an expert at this but i have had errors with my DRO before that were scale related rather than the readout itself (dirty contact/poor contact). To rule this out, could you try switching the leads for scales for each axis over just to make sure it's not an error with the scale?

P.s having re-read this i can see you've already tried that, It could well be a problem with the setup or maybe a duff lead?

Have you tried pressing the "ZERO" key on the top row?

Also try "0" then "ENTER"

Last resort Read the Intruction Manual?

P.S. Just did some digging and found "Select Axis then press CLS"

I have the 3 axis, mill, version but zeroing should be the same.

Key sequence to zero is :- X ... 0 .... Ent. If you want to put an offset in same sequence but insert the offset number.

Yup! That did the trick, many thanks indeed.

Couple of other queries please,

Can you confirm that the Z axis is the left right of the carriage and the X axis is cross slide travel?

How do I use the radius/diameter control please?

Regards,

Martin

Btw, I do not have a manual and cannot find one for this specific model

Martin

I have the same DRO as you. Someone here kindly sent me a PDF version of the manual so if you PM me your email address I will forward it to you.

Ian, PM sent, many thanks

... 'Can you confirm that the Z axis is the left right of the carriage and the X axis is cross slide travel?'

'X' axis is table travel left to right... 'Y' is front to back... 'Z' is up & down

Hi that is for a milling machine. On a lathe the carriage is Z and the cross slide X.

The Z axis is always in line with the spindle. (OK there may be exceptions).

Hi George , I understand that to be the nomal convention, but this DRO for a lathe only has X & Z Axes and I have been told that X mustbe the cross slide in order for the Radius/Diamter button to work but I cannot confirm this in the manual?

Sorry David C , my post crossed with yours, thanks for the ereply.

Martin

X has always been longitudinal whether mill, grinder or lathe.
Some drawings even refer to longitude being X and Y width.

On my Sino DRO, X has to be for the cross slide for the radius / diameter to work. If you look at your first picture there is 'RAD' under the X display - a decimal point appears here when in radius mode. The taper calculation function also requires that X is the cross slide.

FWIW for clarification re axes...

George.
