Re: [Emc-users] hi temp 3d printers, are there any cheap ones?

[Gregg Eshelman via Emc-users]

Look for Kaowool. Blanket or rigid forms as thin as 1/4" Can take the rigid 
type and put aluminum flue tape on it to reflect radiant heat back at the hot 
bed. On my little Monoprice I put flue tape on a piece of cardboard from a Coca 
Cola 12 pack box and slid it under the bed. Helps the bed heat up faster and 
stay a more consistent temp.

For my thermal insulation needs I have been using Bisco Foam RF-120.  It's
a silicone foam with a foil backing one side, very nice to work with and
not carcinogenic.  Good to 200C and is UL94V0.  However, it is an
industrial product, not available to the public and carries a MOQ of
100SF.  However, I can order through my gasket business if I can get to the
100 sq ft: it costs $13.50/sf (pricey), comes on a 36" wide roll and I will
resell it at cost, FOB CA.  Let me know if anyone out there wants some and
I will tally up the requests and see if we can get to the MOQ.

Starting to write some useful G-code I discovered I had to overshoot motion 
then using G42 or G43 tool compensation to approach from the right direction. 
This will produce some extra unneeded motion. Is there any method to get around 
this extra motion approaching from the right direction then using tool

Already done it Art, but I put the fixed OEM hot end back on, I couldn't 
stop the MS hot end from freezeing shut in the middle of a 10 hour 
print.  The fixed one doesn't leak, see previous reply for a blowby blow 
on that.

I'm on glass anyway. With a haze of kids glue stick, adhesion just goes 
away if colder the 260-70. TEPG also warps on the bottom so that temp 
must be held for the prints duration else it comes loose, wrecking 
things loose.

Thanks Art.

I've put the full kit from MicroSwiss on it, but the hot end was a bust, 
so the modified OEM hot end is back on it. The MicroSwiss was plugging 
solid about 2 hours into any print because hot plastic was filling up 
the hot block, migrating up the heat block to the cold sink and locing 
up solid. The OEM hot end has the plastic tubing all the way thru it and 
no hot metal touches the filament until its actually in the nozzle.  But 
due to a lack of any compression against the back of the nozzle, it 
leaks there, running hot plastic down the nozzles threads and filling up 
the cheap sock until it drags on and destroys the print. I took the 
shark bite out of the top of the heat sink, cut that piece of the 
tubeing off about 30 thou longer than the space from the shark bite to 
the nozzle, and used the hot block as a sanding jig to make the tubing 
dead square on both ends so it would seal better against the rear of the 
nozzle. Then I threaded a piece of PLA thru the shark bite, putting 
about a 2-56 sized steel washer over the PLA and against the bottom of 
the shark bite, teflon pipe taped the nozzle and installed it.  Ran the 
PLA into the cold nozzle, and useing it to hold the washer so the PLA 
went thru it ok,  screwed the shark bite back into the top of the heat 
sink, hitting the trapped tubing about 3/4 turn from tight and drove it 
on till tight.  Now my nozzle maintenance consists of warming it up and 
wiping it off with about 4 layers of paper towels to keep from cooking 
my fingers, in betweeb jobs.

So that part is fixed, and all I really need is a hotter nozzle. The 
MicroSwiss ejector drive is sweet. but I wasn't impressed with the hot 
end, its metallic and oversized from the built in shark bite on top, all 
the way to the nozzle.  And when it freezes up, you can drill it out, or 
go heat the whole  maryann on a gas cookstove fire. No amount of 260c 
nozzle heating will telegraph far enough up into the heat sink to thaw 
it out.  So I put the leak fixed EOM hot end back in it, which had the 
side effect of raising the fish mouth on the top of their tube 
connecting the extruder to the hot end, nearly a mm higher, where before 
there was room enough for the TPU to buckle and escape, now it fits 
precisely. TEPG is stiffer so I can put lots of pressure on the nozzle, 
but I can't melt the TEPG fast enough at the 260C limit of the hot block 
to run any faster than 25 to 30 ipm.

That limitation is in the driver cards firmware, so I'd suspect a 
replacement driver card may allow it to run hotter, with the limit being 
how hot the capricorn tubing can be run at.  The OEM white, said to be 
PTFE, tubing is said to outgas noxious funes above 240C, but I'm 
currantly running at 260C for the third flexgear and haven't noted any 
odors. But as of Fridays mail, I have a yard of capricorn to replace it 
as needed. My clue will likely be the leakage.

Thanks Tom.

Long time lurker out here that does some PETG 
(which I think is what you mean?) and my advice 
would be to do two things to your printer.
1. Replace the hot end with a Micro-Swiss all 
metal hot end. This will allow much higher temps, 
but of course you will need to mod the firmware to allow this.
2. Insulate the underside of your bed.  On one of 
my printers, the factory installation would 
struggle to get to 65°C. I insulated with some 
ceramic blanket gotten off our favorite auction 
site and it will verifiably get to 123°C!


This will be a cheaper than buying a new printer. 
There is also talk about loosing magnetism in the 
bed if you elevate the temp much, but I am 
running mine at 85° on an Ender 5 with no problems.

melt the plastic fast enough to make a solid build while moving faster.

Out of the parts for this version of a harmonic drivem I'd like to make
the body cap with the motor mounted to it, and the bearing carrier
because that would allow full current to the motor, and the flexgear out
of TEPG because of its flexing without failure ability.  The rest of it
can be PLA as those parts don't have the motor heat telegraphed into
them.

So I'm now looking for info on an affordable printer that can run the bed
at 80c, and the nozzle at 275 to 280C.  This ender3 pro electronically
limits at 260C, and takes a long time for the bed to hit 70C.  And there
are advisories about not going above 240 with the OEM bowden tube.  And
I have a piece in the hot end that I'll replace with the blue capricorn
between this print and the next, because I am running at the 260C limit,
and 70C bed just to get bed adhesion.

Is there such a beast more suitable for TEPG?

Thanks all.

[Emc-users] hi temp 3d printers, are there any cheap ones?

[Gene Heskett]

Greetings all the 3d printer people hiding in the bushes;

I have found the best material to make flexgears out of, TEPG.

But I've a problem, an ender3 won't go above 260C for nozzle temp, and 
that is restricting the build speed to around 30" max, because it can't 
melt the plastic fast enough to make a solid build while moving faster.

Granted, that's a whole lot of work.

I think first it would be appropriate to not use words like whine or clamor or 
noise.  A comment was made about the people who joined the group thinking about 
LinuxCNC and then left.  It's easy to misconstrue some of these comments or 
words as demeaning or debasing and in general the Linux community has a bit of 
a reputation of replying to posts with statements like:

"This information is on line or has already been answered so do your homework and 
don't bother us with uniformed questions"

Sadly, when someone is starting they don't know what they don't know and don't 
know where to look to find out what they don't know.

Add to that the time line of the internet and postings and the amount of out of 
date material that often shows up far more often because it's been referenced 
often it's really difficult for someone new to get a sense of what to do or how 
things work.

For example, I'm sure there are LinuxCNC users out there who have no idea of 
what a joint is in LinuxCNC.  And there's the crux of the problem with a 
hobbyist who wants to add CNC to his equipment.  They might add a 4th axis.  
Certainly not interested in a 16 joint robot. (Well they might be...)

So that new guy does his research, looks at the web site after googling "LinuxCNC 
Axis" and ends up here:
http://linuxcnc.org/docs/html/gui/axis.html

His friend has MACH3 on WIN-XP but he doesn't and really doesn't want to try 
and get WIN-XP running on the surplus PC he has for the CNC shop.

His friend shows him all the wizards that make simple operations on the mill trivial.  So he reads 
the doc and can't find an equivalent.  It's not an AXIS menu item.  He asks a question like 
"Is there a menu entry or some Wizards like in MACH3?"  and is told: "Learn G-Code.  
You'll need it anyway no matter what".

Notice that isn't an answer to his question.

Another common type of response is "Yes you can add all sorts of screens and things 
like wizards to LinuxCNC."  Nothing more.

Remember, this new user has never written a line of software in his life.  He's 
picked up metal working as a hobby because he likes model trains and would like 
to build a steam engine now that he's close to retirement.  (or some other 
reason that a person buys a mill and a lathe).

So I don't think it's whining or complaining to suggest that a nice feature to add to the 
AXIS interface would be another menu entry for called say "Operations".  And 
fill it in with one item to perform a surfacing operation G-Code program that is then 
loaded.

Then in the manual add a section that shows how to add to that list.  One 
possible approach is to make that list an XML file which can be edited with 
free programs like XMLNotepad.  There's probably something like that in the 
Linux world too.

The main menu entry is "Operations"

Underneath that the name of an operation like "Surfacing" and the file name of 
the program that is run to create the dialog and interact with a user.

The "Operations" dialog on save returns a pointer to the file name and then 
just like opening a G-Code file it's loaded.

Now AXIS has the ability to run Wizards written in any language.  I've used 
this example because I'd like to see something like the MACH3 wizards in the 
Axis interface.

But I haven't a clue where to start and since I don't do development on Linux 
systems (other than Pi or Beagle) I couldn't even rebuild Axis if I wanted to.  
Ie.  I don't have a development PC that has Linux on it.   But I can write 
using Lazarus and test all these types of dialogs on a WIN-7 or WIN-10 PC and 
on a Pi.

And at least I write software for a living.  That hobbyist I've mentioned just 
leaves the list and buys something else.  Doesn't say goodbye.  Just leaves.

And perhaps we shouldn't care.

John Dammeyer


John,

What else would you call it?  They aren't asking for a feature or two or 
three.  All we ever hear is that the "PC is dead, we need a complete new 
way of doing things, and LinuxCNC is not what we want.  Give us want we 
want!"  And this is coming from supposedly accomplished coders.


No problem with new folks coming on board and asking questions, or 
requesting features, or trying to learn.  That's not what we're talking 
about though.

no installation candidate for the pi's buster.

3 out of 4 machines cannot find it to install it.

wheezy apparently got it from the archive, but the other 2 wintel boxes 
probably need that added to the sources.list.

Prefer the CAD program for CAM.

It runs inside LinuxCNC, so of course it doesn't work with Win-7.

That is a great idea!
We know that LinuxCNC has almost endless possibilities, but bringing those
possibilities to work can be cumbersome, and sometimes virtually impossible
for a novice. And it usually takes a lot of time.
So most people would like to try, but eventually prefer something simpler...

Shortly, it would be good to have at least one config where NativeCAM is
enabled.

WBR,
Andrew
