Review on DRO 3 Axis Digital Readout Display +3Pc Glass Linear Scale For CNC Mill Lathe Machine (300+650+800) by Kenny Rossi

I installed this product on my Rockwell 21-100 3-axis milling machine. There are no installation instructions included, but "ToAuto" does offer an install video on YouTube. The guy in the install video made this seem like a "slam, bam, thank you mamm" install process. It's not.Had to make most of my own mounting hardware. The only hardware I used from the kit was the metric screws to mount the read heads, and 4 of the 6 "L" brackets, which all required being corrected to a 90° true angle. All the rest of the mounting hardware was of my own design. The "hardware" (flimsy plastic guides) that are intended to hold the read heads centered and in-place while installing the screws to the brackets leave a lot to be desired. They are flimsy and do not hold the read heads solidly while locking the read head to a bracket.The User Guide requires a fair amount of "WTF are they saying!" scrutiny. You can get a LOT more guidance from watching YouTube (recommend "Blondihacks") on how to use the device.This is NOT a rush install! Take your time. I took nearly 30 days for mine, but I'm retired and I have a LOT of time on my hands.At this point, I'm pleased with the performance and accuracy of the device.
