Default PC based DRO?

Just something that I've been pondering, but does anybody know of a PC based DRO system, please?

I've found Yadro on the net, but the boards are out of stock, but I keep wondering how feasible it is to build one myself.

The other option would be something Arduino based. I've found one of these that works through an Android phone, but I'd be loathe to leave one of these next to flying swarf.

Any help or pointers gratefully recieved!

Cheers
Dave

Android (or "Smartphones") have indeed become a big fixture of our lives. However, I don't think they are yet up to the task of being a DRO display. Imagine being in the middle of a tight tolerance cut and the phone rings

I like the idea of dedicated devices for certain tasks and your PC Based DRO would fit the bill.

this could be fun... also the source code may help you/someone write a dro application for a pc if you are set on the pc thing. you'll need to know how to read different encoders. also you could probably just use cnc software on a pc if it has support for different encoders.

New Android Tablets can be found for less than $100 now. This makes them suitable for use as dedicated devices.

I built a YARDRO. It needs a really old laptop with a serial connection, but the programming is open source. I'm not sure the hardware is available any more.

You might look at Artsoft's Mach 3 cnc controller software. It is made to be used by almost any hardware and can be configured a 100.000 different ways. You can also make your own custom screen layout. I have used it since I built my CnC machine 13 years ago. It was version Mach 1 and I only paid $100, with a lifetime free upgrade.

What do you plan to use for position senders?

And then there is also Caliper2PC.

John,
That's the old version. The new version is even slicker and easier to build
On a serious note, I've been using Android tablet for a DRO for over a year now and a PC before that. (I built the first version in late 2011 when I first got the mini mill) and it's been pretty stable. I had more trouble with the scales being sensitive to noise and ground loops than with the tablet itself.

Thank you
Yuriy

Hi guys,

Thanks for all your feedback on this

I'd planned on using quadrature scales, and also a rotary encoder on the lathe spindle for angular display for live tooling use, and switchable to rpm for general use.

The Arduino solution looks neat, and i already have one of them, but I do like to get hot swarf pinging around, so I'd like the display to be pretty robust. The Shumtech again looks neat, but it's out of stock at the mo, so I'll give them a chase up.

If I went the Mach3 route, is it likely to confuse it if it has no motors connected?

Sorry for what may be dumb questions, but i'm a lot more comfortable with mechanics than electronics...

Many thanks
Dave
