Re: Constant Surface Speed Application for 300 mm lathe #CSS

In my experience with the blu tooth TouchDRO when used on my mill, they give me an accurate coordinate display but manual?milling.(hand cranking).only. Provided you have calibrated first yury?s display. Not difficult as there is a settings in Yury?s "app" to do this.?? I just use the normal Al Basset?s box and an Android Samsung tablet, and I must say this kit works OK. But under my mill rapid power feed the coordinates can lose accuracy, I now this as making comparisons with my 4 axis CNC controller? displays and these are accurate as they are not relying?on Igaging?scales, but pulses off the stepper motor drivers. Not being an electronic wizard, I think the Blue tooth box possibly needs time to play catch up to the rapid movements and also I don?t think it?s an Igaging scale issue. I am suspecting this could be the case with attaching this type of display to a CSS ,if the Bluetooth was somehow connected to display lathe spindle RPM. but I do not know. I don?t see me in the future going down this route. The standard optical RPM display built into the lathe control box works OK.and I also? have a seperate digital RPM display connected to the Arduino on the ELS system which reads the encoder movements. Now this is really accurate and gives on time (no delay) RPM counts. John On Sat, 14 Sep 2019 at 17:37, Ralph Hulslander <rhulslander@...> wrote:
