Maybe if you just posted the flash slider that you use..... Then I could insert it and see if the problem is resolved.

Hey John, That was just a standard slider. I modified my set in Screen 4.

Brett

That is what I just did as well, this is not a flash screen that I modded-

John,

I just tried something for you. Just make the slider bar a little wider, and that seems to make the number a bit larger and then it's fixed!

lol! I'm already there, my friend. I have a weekly backup system that includes all my files for that "just in case" moment!

Yes very nicely doccumented, I think it will be great help and inspiration for others 

Indeed it will, thanks for the link as I'm hoping to build a nice cnc router at one point and yours is a very nice example.

I completely understand the reasons for upgrading, I just hate to bork up my system when things are running well.

I guess the best thing to do is set it up on a PC that I don't have my machine on and go through to be sure.

Thanks fellas-

Just a quick question, why do you guys upgrade to a version that is not a lockdown yet?

I'm just curious as I'm always a wuss when it comes to changing versions-

No sweat, my friend, thank you for the future help on this when I need it

This is the closest I could see on the US site.

The switch doesn't do anything particularly clever it's a light source (often infrared LED) and a photodetector often a photo transistor either mounted in an IR transparent package or has small lenses to stop cross talk etc. As long as it will run on the voltage you need and will provide a sink for the data pin (usual to put a pull up resistor on the output) you may also need to put a current limiter resistor on the feed to the LED depending on what one you get. Oh and ensure it will run at the max frequency you intend but this is unlikely to be a problem.
The thing I worried about is would the parallel port read it quick enough to get an accurate reading or would there need to be some electronic scaling but Hood has answered this one and fortunately it'll bolt straight on. I'll be trying to connect mine to the smoothstepper board (on order) which has a dedicated input for spindle speed (I think).

Thanks for that, no wonder I couldn't find anything on it, Hood speelled it ending with a "C", not a "K", lol!

Thanks again-

I just connect through the breakout, although on my first mill I connected directly into a second parallel port. Only thing you need is the optical switch and resistor and a 5v supply.

Hood, I can not seem to find the data sheet on that switch, any chance you have one? I'd like to give this a try in the future but can't find that particular switch in the USA so I thought I'd try to cross reference it with something else.

Thanks,
Dave
