[Emc-users] First test run on 3D printed CNC conversion

[Chris Albertson]

I shot an iPhone video of the first test with all three axes assembled.
Again, this CNC build is purposely the simplest and lowest cost build I
could do.  I'm still using two 3D printed timing belts and all printed
parts. and the z-axis is held together with clamps.   But as you can see it
can now "cut" the "LinuxCNC" splash screen.

It will eventually have home and limit switches, Mesa card, and glass
linear encoders but I want to characterize and document a low-budget build
first.

This is working out about as I wanted. The budget is still holding about
$350.  It seems to perform well enough to be useful.  My computer has
37,000 ns of jitter so I've limited step rate to 8 kHz on all axes.  Even
so, I get a very reliable 30 mm/second movement on both X and Y.   I should
be able to be better because I have the drivers set to limit current to 2.0
amps with 4.2 amp motors. I think I can improve the 35,000 number.

I'm working on setting up a gamepad  ( target.com/p/logitech-f310-gamepad
 )  as a
pendant.  It is looking like I will be able to do jogs, toutch-offs, and
some manual milling operations with this $20 "pendant".

Re: [Emc-users] OT: Question about Bergerda servo motors and drives

[Leonardo Marsaglia]

Thank you John for your quick response. Indeed I'm talking with Donald too
and it seems really nice and responsive.

About your spindle whining a little bit. Could this be solved offsetting
the 0 speed reference until it really hits 0 volts? I remember I did this
with the yaskawa VFD to really "align" the 0 volts reference with 0 hz or
motion stopped on the VFD.

I think I'm going to order one kit as soon as possible to test it and use
it as a spindle for a live tool on the lathe (with a proper planetary
reducer). But, from your experience I guess it's a sure bet to give them a
try.

Re: [Emc-users] OT: Question about Bergerda servo motors and drives

[John Dammeyer]

I think I paid with credit card.  My initial contact was through Alibaba.  
Later I've had many discussions with Donald Chen.  His English is good enough 
to get by although he might be using Google Translate.  He can ask the 
engineers or pass on questions to them.

I've used the 400W model in step/dir mode.  The spindle 1.8kW is currently used 
in 0-10V with direction input.  One I finish a few things I'll switch it over 
to the second port of the MESA 7i92H and change it to step/dir mode too.I 
find when the spindle stops with 0-10V mode that it sometimes whines a bit.  If 
I twist on the spindle I can make it stop.  I think it's just at some 
indefinite position based on when the voltage input went below the motion 
cut-off.

I had similar noise from the STMBL drive on DC Servos but never with the STMBL 
on the AC servo.  And I don't recall the 400W AC servo making that noise.

Also, I think when the spindle has stopped I may want to add a time delay and a 
specific Spindle Motor Enable so that when it's stopped it's also not being 
held in position.  Not really needed in 0-10V mode.  That might even be a 
parameter.  I should check.

The motor encoder output can be divided down.  The step/dir can also be scaled 
from the 2500 lines to whatever you want.  I ran as if it were a 250 line 
encoder (1000PPR) to match the US Digital (and later CUI) encoder.  The CUI was 
programmed with the AMT ViewPoint software to also produce 250 lines on the DC 
servo.

[Emc-users] OT: Question about Bergerda servo motors and drives

[Leonardo Marsaglia]

Hello guys,

I'm planning to buy some servo motors for a router I'm slowly building and
I remember a few months ago John Dammeyer told me about these Bergerda
servo motors and how good they are.

I would like to know a little bit more about anyone having experience with
these servos. I motsly interested in the E series since they have a 17 bits
absolute encoder and I assume they can be scaled to whatever value you
want. I plan to use them in position mode with pulse + dir steps.

Also, they told me the best way to place the payment is via Western Union,
and I wanted to know how the purchase went for John or any other in the
list. Just to have a little bit more of confidence before trying to place
an order.

As always thank you for your time and help!

Leonardo

OK will do.

If all else fails I can just do what I did on the last one with Chinese
servos.

Let us know how it goes.  We passed on a nearly identical machine here locally 
who's control wouldn't power up.  If the servos had not been so tightly 
integrated into the control we probably would have bought it.

Re: [Emc-users] max motor size that a 8i20 can control

[andrew beck]

Hey Andy.

Heidenhain is not very well supported here in NZ.

I went down that path already on my last machine and won't do that twice
lol.

They are actually moving and just want it gone now.

And the 25k nzd was over 10 years with all the problems it had.  It's
almost as if it has a dodgy ground or something

But I really like linuxcnc.  So I'll put that on it.  And my whole workshop
will be running linuxcnc.  I have used fagor and semiens controls a lot and
still really like linuxcnc.  You guys all do a great job.

Linuxcnc has a some issues of course but it is very capable.  I mainly miss
the conversational stuff.

Regards

Andrew

More likely, they hired some tech to work on it at $300/hr, he worked on it for 
a week +parts and he couldn't figure it out, then they got fed up hired another 
guy, same story and then wrote the machine off.

Did you offer to take 25k off them to retrofit it?

(Though if Heidenhain couldn't fix it, I would be wondering what might be 
wrong. 25k would be a whole new controller, wouldn't it? )

ROTFLMAO!

But even that is informational Andy, I was wondering what the conveyer 
looking thing was for.  Now I know. ;-)  In my travels thru the 
broadcast industry over the last 60 years, I have never been in the same 
building as a big, production oriented machine like that.

Looks like you might get 20 years before the chip conveyor can't reach out
of the hole. :-)

I'm jealous.  But I'd have to put up another building with foundations 
20'+ down to solid stuff, my whole place is sitting on yellow clay fill.  
Which it would ink into about 2-4" a year.

Congrates Andrew. And we look forward to a blow by blow as you bring it 
to life in its new digs at your place.

I think that only lists the small range of tools used by Haas?

Not all pull-studs are 45 degrees, for example. There are 90 degree and 60
degree variants. (plus DIN2080 )

Wow: that's a beauty.
Did you give it a wax and polish to get that shine?
