Re: [Emc-users] Learning LinuxCNC Youtube Channel

[Chris Albertson]

It's good that you are doing this.

It you want to improve the audio the #1 rule is to place the
microphone as close as possible.   It sounds to me like it is far
enough away to pick up so room echo.   I'd invest in a good cavalier
microphone.

Better method is to do the audio as a voice over after you have edited
the video.  Then you can use a studio microphone in a quiet
environment.  Doing the voice over later also allows you to edit out
mistakes and those little things you don't really mean to say like
"ah" "awe" and "you know" and so on.   Studio microphones can be
really close up.  I set it up about 6 to 8 inches and use a pop filter

Thanks Danny.  I'll have to investigate the little booklet manual that 
came with it to see what sort of a braking R is needed, and a wild guess 
at what its wattage would need to be to survive a 50 peck g33.1 hole 
tapping session.  I think it mentioned it, but it wasn't something I was 
concerned about at the time I was verifying that it would at least run.

I haven't used a braking R per sei with Jons amplifier, but I do know it 
will dump back into the supply, blasting it from 125 volts to enough to 
clear a 7 watt 127 volt night light style of a C7 lamp in just a few 
cycles of that.

I hadn't even considered the need for the braking resistor, so that will 
obviously need to be arranged for.  Glad you brought it up, thanks.

Re: [Emc-users] Using a vfd vs G33.1

[Danny Miller]

Without an external braking resistor, the deceleration is much more 
limited.  What happens is the back EMF charges the main bus capacitor, 
and it will go into an overvolt error and simply freewheel to avoid 
charging it further to a point where it will damage the cap.

I have a 3KW air-cooled milling spindle.  It had no problem with a 2 sec 
spinup time to 18K RPM.  However, it went to an overvolt condition with 
a 3 sec spindown time, I had to bump it to 5 sec.

The X200/WJ200 manual shows braking torque is as low as, I believe, 
20%-40% of spinup torque without a resistor.  With a resistor, it can be 
as high as 150%.

 From my experience with the Hitachi X200 VFD, I didn't see any 
visibility to current RPM.  The acceleration period I had as a 
controllable parameter was a fixed time, i.e. 2 sec to 18K RPM but if 
you only specified 5K RPM target, it'd still take 2 sec.  I presume that 
also meant if you were at 5K RPM and specified 6K it would take 2 sec to 
accelerate which is unnecessarily slow.  And keep in mind the 
acceleration isn't a parameter provided with the RPM set.  It would be 
set separately and is part of the configuration.  I don't even know how 
to program those config parameters from Modbus.

I think the manual described a 2-stage option, X seconds to RPM1 then Y 
seconds to RPM2.  Doesn't really change things though.  I didn't see an 
"seconds per K RPM of speed difference", as in, an ACTUAL acceleration.

[Emc-users] Using a vfd vs G33.1

[Gene Heskett]

Greetings everybody;

Given that I note the vfd's seem to have an adjustable accelleration 
control, and that my couple of hours playing with it from its own front 
panel, I am led at ask the question of just how fast can one of these 
things be reversed from say 1000 rpm at the motor spindle?

I ask because my present setup, using the OEM PM DC motor which is all 
gear drive to the spindle, one of Jons pwm servo amplifiers and a 125 
volt dc supply, reversals at the turn around depth of this cycle of a 
peck tapping operation, with the spindle doing 300 rpms, is a very small 
fraction of a second, far less than 30 degrees of rotation.  Based on 
its reversal performance at 2500 rpms being a slim second, I am 
concerned that the vfd may not be able to reverse so quickly, and will 
impact my use of G33.1 because of the turnaround over shoots.  On my 
lathe, with its fragile drive train and a 5" chuck, this overshoot is 
between 2 and 3 turns at 250 running rpms.  Usable, but if I don't stop 
it soon enough, the tap may bottom out and break.

What has been the experience of others using smaller vfd's and motors? 

Can you still do rigid tapping safely?

Thanks all.

I just found some notes in the wiki indicating that stuff was supposed to

[Emc-users] Getting rid of useless Z motions.

[Gene Heskett]

Greetings everyone;

I noted that at the bottom in the (sim) axis.ini, three entries for some 
tool changer presets, like TOOL_CHANGE_POSITION etc.  So I copied them 
to the 2.8.0pre2-yadda on the GO704's axis.ini.

WHat I want to do is to have it use that data IF its going to cgange the 
tool, or ignore it if the tool is already loaded.  So I expected it to 
work, and put a comment () around the G0 Z5 that I normally preceed an 
upcoming tool change.  It was ignored, and I wound up looking at the 
please load tool 2 requestor, with the tool sitting at Z0.1.  So I hit 
the esc key and put that G0 Z5 line active again.  Since my Z can't go 
any faster than 40 IPM, that, if the tool is already loaded, is about 20 
seconds of time wasted running up the post and back down again.

Is there some other magic incantation to make that work that I got stoned 
(high sugar) on a bowl of ice cream and missed the memo about it?

Thanks for any hints.

Since thats also tied to a huge gantry machine they likely want north of 
7.5G's for, thats way out of my pay grade AND occupies too much of what 
I have under a roof.

But the video's did give me an idea for a small ATC I could mount on the 
table end opposite the X motor, perhaps with a 5 position wheel, and 
whose weight would at least balance out the weight of the motor on the 
other end of the tale.  Since the tool carrier wheel would need to not 
interfere with the tables use, the whole thing would have to swing off 
the end of the table & to the rear, and swing in to get under the 
spindle when in use. I like, and since I do have room there, might 
investigate that with some plywood mockups when I am done with these 
blanket chests. I tend not to change horses mid-stream.

Well, this has got me intrigued.

What are the ATC spindle options nowdays that would work for a wood router?

http://www.blurrycustoms.com/#!store/cu2p/!/AVX3/p/35336572/category=9308353 


Cheapest I see is a $3600 one.  Which is expensive in my book, but less

Not the same make, but they look identical. I still have 2 empty's to 
fill up, and I see I can buy those in onsies & twosies. I need to make a 
rack since my tool changer idea petered out for lack of room.
The rack, at least a 2 shelfer might be something I can make out of the 
leftovers of this totally shitty Mahogany.  One shelf for the full inch 
set of R8's, another for 20 or so eventually, of these tts er20 things.

And I'm not awake yet, leg cramp got me up fast about an hour ago.  Ate a 
bannana and it seems to have relaxed now.

I should have typed "these" below, since I was referring to the collets.  
So I bought a 10 pack of 1/8" and all the 1/4" (8) another seller had at 
$2.29 a copy, and a full set of 1-13mm metrics.
