No one can argue the fact that Art has a beautiful mind.  He sure is letting his artistic side shine with gearotic.

You need to go  to Config Menu then Config Pkugins and enable it

It will not appear in the plugin control drop down until you enable it, close mach and reopen mach.

I agree Tweakie, seems now if you have or more often had something that worked well they would change it so that it would be more environmentally friendly and ruin the product in the process.  On the other hand we should defiantly do all we can to lessen our impact on the environment.  Lessen in my definition means to actually lessen, not just create the problem and potentially cause more by shipping it half way around the world just so it isn't "in our back ward".  It is crazy the way we live.  We work all the time so we can pay others to raise our kids, grow our food, do our hunting and fishing for us, etc.  How about embalming our dead?  Why do we still do that?  I maintain it is out of shear ignorance.  I'd rest a lot better if they just put me in the dirt.  Why not just have a picture of the deceased to pay your respects to?  Keep the fancy box as well.  I was born to be fertilizer one day and not a further burden on my surroundings.     I think I'm like a lot of others.  Aware that we do some really dumb things and willing to change but how do we go about doing this?  First thing that we can all do is eliminate excess.  I have been working diligently on this for a few years and all my life by many standards.

General Mach Discussion / Re: Accuracy of Homing Devices? Pro's and Con's of Different Sensors

« on: October 15, 2012, 07:12:58 PM »

No matter what type of sensor or switch you use it will not be super accurate all by itself. For really accurate homing it is best to use a combination of a home sensor/switch and an index pulse on the axis motor itself. The home sensor/switch and the index pulse are seen at the same time the controller considers this 'home'. Since the index pulse is based on the angle of the axis motor itself it is very accurate.

I recently stumbled across this powerful statement and was wondering how one accomplishes "an index pulse on the axis motor itself" and if it's possible on a regular stepper motor without a shaft encoder.  I'm intrigued by this concept and would like to learn more.

Anyone have further info on the matter or links?

Thanks!

This thread may help explain that and give an alternate idea on "finer homing" by mechanical means.

Stacking them deep and selling them cheap................. that is an understatement for you Hood.  I'm glad you got my quarters all cleaned out.  My matress will fit just fine in that cabinet.    Maybe you could raise rabbits or water buffalo in the extra space of the cabinet?

I didnt realise the  workshop practice manual I had written was available over your side of the pond

Oh yeah, we got it and you have been learning me some stuff. 

Steve,

You forgot one:  Measure with a micrometer, mark with chalk, cut with an axe.

Can I use this Ray?
