Review on DRO 3 Axis Digital Readout Display +3Pc Glass Linear Scale For CNC Mill Lathe Machine (250+350+400) by Christopher Holker

As a self-proclaimed hobby machinist, I did a lot of research to determine A) what DRO system I wanted B) respective scale sizes that will fit my mill. This was my first DRO install which resulted in 10 working hours, but trust the process & enjoy a couple cold ones and you'll be okay. Hopefully the pictures & information below will serve as an aid in making your DRO purchase/install.SPECS USED - ENCO Model 100-1599 (49" x 9")-Longitudinal Travel (X): 35" - 37" Scale-Transverse Travel (Y): 12" - 14" Scale-Vertical Travel (Z): 16" - 18" ScalePROS:-Overall good quality scales/encoders/box-Numbers appear to accurate, but I will conduct further testing to verify-Quick shipping & good packaging-Great communication from sellerCONS:-Hardware (socket cap screws, washer, brackets) is generic and could probably be disregarded-Manual is quite poor, rely on YouTube as a better reference-Shield covers are thin and don't allow for much room for mounting holes, but it's better than nothingTIPS:-Start with X, then Y, and finish with Z axis - Easiest -> Hardest-Use a digital level to estimate positioning before dialing in with indicator-Make sure you have plenty of hardware on hand! This includes nuts, bolts, taps, and various sized washers-Slightly & carefully ream ends of mounted hole to accept 1/4-20 bots (common & cheap to acquire)-I recommend custom brackets for Y & Z axis install, and baseplate for Z (depending on machine model)-Wait till the end to perform cable management. Use oversized P-clamps where slack is needed (Y & Z)
