Under normal jogging commands the two servos control the ends of this gantry

hit the bridge forward or backward it will flex and wobble enough to displace 
the dial indicator +/-0.03 and it takes nearly a dozen wobbles to dampen it.  
But on the ends the servo's only have a few thousandths of give.

I'm less concerned about the actual stiffness and more worried about dampening 
the wobble.

Re: [Emc-users] Semi OT: Variable speed DC drive for Fanuc brushed DC spindle drive

Thank you for your reply.
If you get the Machdrives please let us know if they are easy to tune.The Tuna 
software looks easy to use and appears to be full featured but you can never 
tell till you use it.If you do order, order soon. International shipping takes 
several weeks.I asked if they wanted me to be a stocking US dealer. They said 
no.

I went with the 160 volt drives as that gives me some voltage head room to 
prevent shutdown on a voltage surge.

Be safeDale

We just purchased a Mori Seiki SL3 lathe that's going to be
retrofitted with LCNC because it has no control.

The machine has a brushed DC spindle motor and from what they told me the
DC drive was not working (I would like to check this but I couldn't find
any info or manuals for this drive, the model number of the drive is
A20B-0008-0372/02). I would like to keep this motor because I like the idea
of having high torque at low speeds because I plan to use a milling and
hobbing attachment with this lathe.

I'm trying to find DC speed controllers of 15 kW or so, just to take a look
at what it's available but it seems difficult to find something that big.
Do you guys recommend any particular brand or source to find such a speed
controller?

Thanks as always.

Re: [Emc-users] linuxcnc openlung ventilators

[Dale Ertley via Emc-users]

  What is the chance that a BIPAP (twopressure system) machine could be used as 
a “first line” for a ventilator?  
A CPAP (single pressure system) may also work.
It might even work with an O2concentrator.

Pressures could be raised andlowered if necessary.
I don’t think it could be used with patientintubation.  
There are millions of them outthere.

Thoughts that come to mind:

Outback products are top drawer

This seems to be a 24 Volt battetry system, my cheapish solar charger 
has set battery parameters: flooded LA, Gel LA,  but also a user 
selection that can be set for whatever such as LiFePO4 or any other 
chemistry if the user knows what they want. I would assume the Outback 
has a similar feature but I haven't found it yet. I am collecting 
LiFePO4 Headway 38120 cells when good deals come along. AlarmHookUp 
seems to be a good source of batteries, but not totally risk free.

Direct thermal refrigeration may make sense.  Sun heats a 
water loop, drives off the ammonia, and then it is 
reabsorbed to cool the cold side.  You could do the same 
with lithium bromide, although that is a salt that could end 
up clogging things.

When confined to a building, it can cause MASSIVE 
explosions.  The fire marshalls just LOVE ammonia systems!
