      Hi folks,

      Once again I am asking for the help I know you can provide. The 2 Axis Sino SDS6 2V DRO on my Chester Super Mill has thrown a wobbler, half of the keys no longer work and I cannot get it to do a PCD function. There is no hard reset on it as I understand, so it would appear that a new one is probably going to be on the cards.

      I would really like to upgrade while I’m at it to a 3 +1 axis LCD DRO, so that I can also have a readout of the main Z axis on the raise and lower plus a readout of the quill as well. Might as well eat my cake as have it.

      The question is does anyone have one that they can comment on regards accuracy, reliability etc. I have glass scales currently.

      Thanks all,

      Daedalus.

        Most china DRO use the same logic signals.

        The pin outs of the 9way D-types vary as do the wire colour codes. Adverts in Ebay for DRO have details of which pin does what – compare etc etc.

          I am installing a 4 axis LCD DRO on my mill at the moment.

          It’s from BMR measurement but I think that it’s a Aikron unit.  Seems good, a metal cased unit, it also has a spindle speed input which as I have a VFD will be useful. They are on the web and Sino also make a 4 axis unit. There are lots of others on the web. I did not want to buy direct from China as I did not want the shipping/customs hassle and BMR have been very good to deal with.

          Accuracy? I would suggest that any unit is only as good as the scales, I am using 5 micron glass scales. The problem with testing at home is am I checking the DRO or  just testing how good my test gear is? It’s also too cold (10c) in the workshop ATM for things to be that accurate. In what testing I have done it does seem good.

          Edit: Mounting the scales parallel to the machine axis is also important for accuracy.

          Getting the correct length scale for the quill is a challange and may involve cutting the scale, not so easy with glass? I have also found that the flexibility of the lead for the quill may be a problem? I’ve yet to complete the quill axis.

          Cheers

          John

            There is probably a connector from the main board to the display. I would power down and take the back off and see if wiggling the wires and connector of such a plug changed things. It may be a single poor connection if half the keys  are not working.
