well - If I can get it running - I now have a 5.2kw generator.
clean or dirty power?
inverter or alternator
ok, so dirty power =)
what powers the inverter?
not good for electronics
Jymmm: please. It is ac generated pretty close to the same way the power company does.
skunkworks: example: http://www.hondapowerequipment.com/products/modeldetail.aspx?page=modeldetail§ion=P2GG&modelname=EU2000i&modelid=EU2000IAN
That one ues inverter so it's a nice sinewave
skunkworks: This one does not http://www.hondapowerequipment.com/products/modeldetail.aspx?page=modeldetail§ion=P2GG&modelname=EG3500&modelid=EG3500XK1A
But it's good for power tools and such
this is a normal 3600 rpm generator that makes a sin wave like your grandfather used to make.
Bet you it's probably a modified saw tooth wave
heh - a picture of a similar one
[02:14:47] <skunkworks> http://www.laptop-junction.com/toast/sites/default/files/Generac-NP-52G-rv-generator-4.3Kw.jpg
inverters will generally give a poorer output than a decent generator/altenator
its expensive to give a good sinewave in silicon
until you start overloading the thing

have you added manpage to git?
i got "RTAI:ERROR: unexpected realtime delay on task1 this message will nonly display once persesion" what i do wong?
when i click play button ...but g-code was running
im using gecko stepper

hello Duckie, you have a question?
how config a sensor in the hal file (detect true or false)
you need to ask a more specific question
i got a sensor that must detect if the cylindre is there or not (true or false).
how configure this in a hall file from emc. (then it show on the right on the panel a led -> on or off)
look at one of the example pyVCP (python virtual control panel) examples
where ? link?
you mean this http://linuxcnc.org/docs/html/hal_pyvcp_examples.html?
yeah, that's one of them. there are a few others on the website
i create the pyVCP for my pin01 (Magneto sensor), but it detect nothing
cradek_ is now known as cradek
watch the pin in hal configuration first to make sure you have the right input
anyone in here have the Super-PID
i want it
what's a super-PID?
simple way to intrigate whole channel :)
I want a small mill, and a rEvo
and world peace, maybe.
atmega: but first - small mill? :)
Speed controller for routers..
that's easy, just buy one
I just trying to figure out the components on the AC side.
Need part #'s of the optos
btw what's cost of parts for small simple mill?
dunno about parts, but assembled and shipped is $950us :)
heh, it's 3 of mine month salaries :)
hmm... I'd say you are vastly underpaid :(
heh, working in science here is equivalent to have extra small salary
i got: RTAI:ERROR: unexpected realtime delay task 1
f iuse LPT1 with gecko stepper, what setting should i choose on configurator selector?
the one with step-dir
is it stepper-mm ?
never mind.. ill look again.
JT-D510: anything I can do wrt documentation?
[19:46:38] <skunkworks> http://www.youtube.com/watch?v=0I025iSr5jU
That's quicker than ost I have seen
[19:49:22] <skunkworks> http://www.youtube.com/watch?v=VmjhUvA3YLE
that's pretty neat, did you make the nozzle?
good evening.the limit2 and limit3 and mux2 component not can load on base-thread ?
motioncontrol: in the man page for a component, if it says "uses floating point", you cannot load it in the base thread. the base thread does not provide floating point.
ahh ok i load it on servo-therad because have error limi2 no fp on base-thread
I posted a bit-mode mux2 (well, actually a mutli-pole crossover switch, but functionally similar) to the mailing list last week which works with bits and runs in the base thread.
cradek, yes i have modified a mux2 float in mux2bit and compile it, fuction good
for base call how can modified ?
motioncontrol: This might do what you want: http://thread.gmane.org/gmane.linux.distributions.emc.devel/3744/focus=3757
motioncontrol: You might need to add the "nofp" switch to your comp (and to mine too, I suspect)
[20:27:35] <andypugh> http://linuxcnc.org/docs/html/hal_comp.html
andypugh, the float not can add at base-therad
andypugh, how can dowload the mux in base-therad ?
What signals do you want to mux?
As long as all your variables and pins are integer or bit, and you have the "nofp" option in the comp file (before the ;;) then it should be base-thread compatible
You just can't do anything with floats in the base thread
Can you rework things to use ints instead?
no bacause on mux have analog out
the question is:
if i have motion control on servo-thread, the mux component switch the analog on servo-thread have the some velocity refresh is good or the mux will more fast for a fast refresh ?
What do you have in the base thread?
only jog-wheel base count
If it's a PWM then I suspect that the PWM would not even work if it's input value was changing every base-thread.
what do you want to read the output of the mux?
i want pass : axis.0.motor-pos-cmd
that is an output of the motion controller, so it only changes when the servo thread runs
i have pwm on servo-therad
motor.-pos-cmd only changes every servo thread too...
now if pass it on mux2 componet
You need the PWM make-pulses in the base thread, and do-calcs in the servo thread. (I might have guessed those function names wrongly)
mux2 componenet is on servo-therad is good ?
no i have pwm on servo, canghe it on base ?
i use mesa card on analog no stepper
The make-pulses function needs to be in the base thread. the update function needs to be in the servo thread.
you probably have no use for base thread at all then
Ah, in that case, yes, that's fine. The Mesa card has its own implicit base thread.
i have :addf hm2_5i20.0.read servo-thread
addf hm2_5i20.1.read servo-thread
addf motion-command-handler servo-thread
addf motion-controller servo-thread
addf pid.0.do-pid-calcs servo-thread
addf pid.1.do-pid-calcs servo-thread
addf pid.2.do-pid-calcs servo-thread
addf pid.3.do-pid-calcs servo-thread
addf hm2_5i20.0.write servo-thread
addf hm2_5i20.1.write servo-thread
addf hm2_5i20.0.pet_watchdog servo-thread #enable if fw supported
addf hm2_5i20.1.pet_watchdog servo-thread
i change all in base ?
Yes, that's fine. With a Mesa card you can actually delete the base thread.
one moment , is correct on servo or base ?
ignore the base thread, expunge it from your mind, cast it aside and ponder it no more.
i have on base only jog wheel encoder component
Why not have the encoder on a Mesa encoder component?
because the channel are full
Ah, good enough reason.
Then put "update-counters" in the base thread and "capture-position" in the servo thread.
now if i use a mux on servo and update analog on it is good , because all component , all system refresh the some frequency ?
good thanks andypugh and cradek
how configure a sensor (for detect cylinder) in stepsconfig and hal
You can't really do it in stepconf
for the steps wizard must i use "amplifier enable" for the sensor or digital output...
how then, my sensor use pin01
stepconf is just to get people with simple setups going, really. Once you get onto more advanced stuff you will need to edit the hal file directly.
Should make the HAL file clearer to you
Then all the HAL functions are listed under "Realtime components and kernel modules" here: http://www.linuxcnc.org/docview/html/
ah, i place this in my hal file net sensorcyl => parport.0.pin-01-out
but it give me "false" always
some 3d printing tests today
[21:54:44] <awallin> http://www.youtube.com/watch?v=0I025iSr5jU
and this: http://www.youtube.com/watch?v=VmjhUvA3YLE
those massive gears are mesmerizing
Very pretty, if a little ostentatious.
gear sizes were probably from some reprap build-guide.
andypugh: nice work
well - you too!
awallin: nice work!
Is that bed plate the size of the machine? It looks like you could 3D-print canoes.
the xyz table is an old Isel table. I think the xy area is A3 paper size (600x400mm or similar)
only 90mm z-travel
Canoes for hamsters then.
awallin: are you happy with it so far?
awallin: nice. That all EMC?
with the extruder we are still just learning how to print things nicely
What do you have controlling the extruder Axis ?
Connor: yes, temp-control and extruder control were added to the standard parport/stepper config
there is a stepper drive which takes step/dir signals that drives the extruder stepper motor
andypugh: here's that same Isel xyz router table in 2006: http://www.anderswallin.net/2006/04/the-new-deck-takes-shape/
You doing 5D with it? or just turning the extruder on/off at a set RPM ?
it is configured as the A-axis in emc, so to emc I guess it looks like a 4D machine
the temp-control is not an axis/joint, it's just a separate PID loop in HAL
Not in that regard.. 5D means XYZ + Extruder + acceleration
to me 5D is a camera made by canon, but OK...
yes there is acceleration control on the A-axis
Yea.. strange crap coming from the printer community.
cool so the A axis Ramps up down as does XYZ
What STL-->Gcode program you using? Skeinforge, ReppSanpper etc??
yes, now the accelerations are set quite high so it's not visible/hearable
these tests were hand-programmed, I haven't had time to look at STL->gcode
If I get inspired I might do something with opencamlib, but it will have to wait until January or later
AHH. Okay. That was my roadblock.. Their is something called Ooze Bane in one of them (SF I think) that reverses the Extruder stepper for a 2nd then stops it so you can move to print a different area so it doesn't leave a stray thread.. that's really nice to have
Be sure you post up you hal setup for the axis and pid stuff.. I'll be getting mine up and printing pretty soon.
BTW, Nice gears on the extruder.
the gears are courtesy of our in-house workshop, I can't take credit for them :)
You using ABS or PLA ?
still, really nice looking.
this is ABS
3 or 1.75mm?
I've got both in ABS and 3mm in PLA.
along with a geared stepper extruder from makergear.
I think the extruder head is 0.5mm, not sure, the head was bought from a shop selling reprap stuff
you in UK ?
land of nokia and linux, finland...
Ah. okay. still, on the other side of the pond from me.
Heating build platform for ABS...
when doing larger parts..
we have a Veller heat-plate for soldering smd-parts. I think we are going to try that.
you only need around 40-50c
similar to this: http://www.soldertechnic.com/weller_accessory/image005.jpg
ok, I just heard 100c from somewhere
Maybe the Heat platform needs to be hotter.. dunno.. people saying 40-50c for enclosed unit..
high tall was each layer?
we moved 0.5mm up for each layer
I think the extruder nozzle is 0.5mm but the plastic gets plattened to something wider (0.7mm?) in these tests
you can play with different heights for that.
should be around .58mm.
