GCS900-2D DRO change mode ?

(1/3) > >>

Hi
I cannot seem to change mode from a MILL-3 to a LATHE-2. It might have helped if I had the manual, though not necessarily so.
This is a cheapo DRO which I ordered with 1u resolution on AlieExpress. When it came 5u was supplied. I think they sent the wrong scales. Went to dispute and I got ~ 30% off. This all happened some time ago.

However I figure I can use it on my lathe, but its set to MILL-3 and I can find no way of changing it. I can get into the setup routine and change the axis resolution and other params (by holding the '.' button on power up) but it does not give the option to change the mode. The manual has disappeared into the nearest black hole, doubtless it will turn up when I no longer need it.

An earlier version had an s key on the left hand side of the display, but although the panel has the 's' key marked there is no button.

Any assistance greatly appreciated.

Best Regards

Not sure if this is applicable but I seem to recall an old thread where something similar was discussed.

 I think there is a hidden button somewhere., maybe just a little hole that needs a pin.

No holes or hidden switches. I took it apart to see if there was anything like that and failed  :scratch:. Just a single pcb and 5v psu, only wiring was to 9 pin D connectors on rear panel.

@ John Rudd
Thanks for your interest. I have a copy of that, but sadly these instructions seem to assume that you can get to the setting during the setup routine (p7) , which isn't the case, as it never appears.

The membrane switch panel does not have a switch at the s position and is flat in that area, despite being printed with an s for one. My other two DRO's are the JCS900 flavour and they both have switches in that position, as indicated by 'clickable' bumps. When I ordered it I thought it was just a clone pf the others, but the axis and zero switches are in different positions also. Likewise the alternate reader head wiring scheme is used , pins 2-gnd +6-9 for supply and signals, vs pin2-gnd and pins 1-5 for supply and signals.

Many thanks for your help.

Best Regards

So there is space for a switch at the position you stated? What if you fitted one temporarily wired in?
