Brian when they become available I'll send you one.

The importer here is out in China at that factory now.   So it's only a few weeks, I'll get two when available.

Acetal is just another name for Delrin.  The original part was probably a compression moulding (bakaite)  It's for a 1920's Austin 7.

There is another type I'm running which is similar size but more curvy!

The part was modelled in OneCNC XR2 Mill Expert.

Why do the PID loops and all the other stuff it can be done in the card :) It is all time and I think they have more time to work at that level. Art and I are doing support and adding to the code to make it work better for the users. We look at the hardware and there are only about 1% that will benefit from the work. We like to add code that will help 50 +%

You can mail the doc's to me at brianb ( AT  ) newfangledsolutions.com , looking forward to seeing them


Brian

Just emailed them to you.

Well I guess there are pro's and cons. EMC has to do the PID, read the encoders and set a velocity voltage, not sure what Mach's burden is with the various smart cards.

I shall be trying EMC2 though just to get a feel for what it's like.

Shame about that, they look to be fairly well thought out cards,  I shall be trying one of them with EMC2 sometime.

Funny the EMC2 guys seem to say the oposite, they don't want to support any so called "smart" cards.  Nothing as strange as folk eh!

Where should I sent the docs on the Leadshine motion controller?

More video!

1st op on a vintage car radiator cap.   Material is black Acetal.   Ran 160 of these yesterday.

Rendered pic is the finished part, although black doest render too well so I chose a brassy colour!

Art, Brian

Not sure where to put this or if there's already a thread on the subject.

Particularly interested in what status the work done on the Galil cards and even the Deltatau card is at this time?

I mentioned in one of the threads here the soon to be available Leadshine card from China, I now have the preliminary programming docs for that device if you are interested.

Any interest in the Passive boards now supported by EMC2?   like the

Plus the others.

Hood.

Sounds like a typical encoder signal loss problem

Are you sure your encoders are wired correctly?   What encoders have you used?

Did you get any of the inrush current limiters?   HIf so how well have they worked for you?

Cor lot of "?" there lol..

It probably doesn't matter.   What you running the transformer from?   Is this a 3phase transformer?

Hood.

Maplin do a 18amp one for a couple of quid.    http://www.maplin.co.uk/Media/PDFs/N96BT.pdf

The 18Amps is steady state current so you might be oK.    The inrush current can be many times this though.

I've seen this blow huge bridge rectifiers, so it's not a small problem.

Hood.   The fuses popping may just be the inrush current on the transformer. Well in fact it's almost certainly that.   

Sometimes they will trip sometimes they won't, it all depends on where the AC cycle is on power up.

You can get iinrush current limiters.  These create a resistance in serses with your supply to limit current, but warm up and change to low resistance.
