Not so Ron. Lead screws and ball screws have problems, expensive and above a certain length suffer whiplash. Top commercial stops use rack and pin...

Anti backlash is easy. Speed( fast ); Stepto( target + 10 ); Speed( slow ); Stepto( target );

The other way round, because Python is interpreted and object based you run the risk of it being too slow for some things. But if you wanted a slick...

Big smile time ! A long time ago I wrote a package for a big machine tool in Turbo Pascal. Basically a big database to create machining lists for timb...

Tell me about it ! It's frightening. I am continually looking up C syntax these days, thank goodness for search engines. 3 months away, I hope whate...

I will, within reason, I'm not here to offend, rather to put something back in. If I'm offering free advice it's on my terms in as much as here is wha...

I must point the finger at you. The marking on an LED is so that you insert them correctly. There is no light if connected in reverse. But you wil...

You are hard to please. I highlighted the code. Copy. Open Arduino 2 - new. Paste over empty sketch. Compile. Perfect. I have found, usi...

Sorry, it's perfectly readable here, what goes wrong at your end ?

The problem being that the inbuilt LED is not consistent across Arduino boards. So telling him to use an external LED makes it easier. Reverse biass...

Another Olde Farte. I'm 79. I wonder if Bill could do an electric Zimmer Frame with GPS so we can get out a bit and always return home.

Damned impressive though when you see them climbing onto a box and down the other side. Of course I/we see only what they want us to see, they never...

You have no mountain to climb, you've already climbed it. The Arduino environment a stroll in the park. // find the on board led pin Take a ch...

We can also screw up badly especially in the cell phone era. I watched a YouTube video a while ago. USA. The amateur video set a challenge, his ...
