RWG-OSD #3 Making Custom Profile Cutter For Slide Wheels - Bearing Selections! OverSized Delta 3D Printer Build.


https://www.youtube.com/watch?v=oorTJ3EH7Kg

~Russ

Quick question on the wire EDM machine: does the cutting generate heat in the material being cut?

The reason I ask is that cutting permalloy or mu metal is difficult to do because heat destroys the magnetic properties of the material. I've been able to do it by cutting slowly with a hack saw or milling bit that cuts slowly and makes chips rather than abrasives which generate heat.

 I understand from your video the wire EDM machine cuts under water so it would carry any heat away rapidly but if it heats the material it would alter the magnetic properties before the heat is carried away.

Have you seen anything about cutting permalloy or mu metal with this machine?

it should not generate heat, however from my understanding the Mu metal needs to be treated because its structure changes?

~Russ

After shaping it can be annealed to obtain the best magnetic properties. But heat generated during the shaping can alter the crystal lattice of the material before annealing which will change how well the annealing works.

ok, yeah this stays very cool so i would say that just the few atoms on the edge would change...

#7 Assembling the Skate Plates / Belts and Wheels!

In this video I finish the plates using the hand drill, Tap and other goodies, then put the belts and wheels on!

#11   Making The Bed Plate And Cutting Glass!

In this video i go over what i went through to get the base plate for the heated bed made as well as cutting the glass for it. more to finish the mounts in the next video!

hi.
where i can find parts ,drawings ,3d files ,software for it ?
it say open source but no files in here
thanks

Hi!

its not finished yet so i haven't uploaded any files. everything is in sketchup, do i dont have any dimensional drawings... yet. but everything in sketch up is to scale. 

since this is a custom build from the ground up i will post more drawings once further along.

 i should post this on reprap wiki!

let me know I'd be happy to send you the current version of what i have in my drawings...

although like i say its not finished... :)

also i haven't updated this page with the rest of the videos,  updated page here:
http://rwgresearch.com/open-projects/3d-printing-research/oversize-delta-3d-printer/

let me know! thanks!!
~Russ

~Russ


 

sure send it ,thanks btw :)
i'm not that bad with sketchup ,i will find way to do 2d from 3d thing
i have some copy of copy 3d printer ,,ctc dual extruder,,
but watching your videos ,i just drool with idea in my mind ,""me want one huuh"" :D
thanks again

 

do you have any of your stuff posted on line?

would love to hear some of your ideas :)

I have plenty of my own and that's why i haven gotten it done yet ! lol

I have attached the current version of the RWG-OSD V1.0!

please do give feed back and changes you make,

~Russ

also attached is the unfinished PCB's i'm making, there incomplete as of yet...  still working on the bottom one.

you will need Express SCH and PCB to read those files.

thanks ! 
question ,can i use one of these kit's for electronics ?

http://www.ebay.co.uk/itm/3D-Printer-Kit-RAMPS-1-4-PCB-Heated-Bed-LCD2004-Controller-Mega2560-R3-A4988-/291822790721?hash=item43f1fe6841:g:AlgAAOSwqfNXjfBG

minus hot bed
how i understand u use only glass in your version so will i .

hey,

yes you can use those electronics,

that's what i use on my other delta, works fine, make sure you use that LCD, the graphical LCD will slow the system down fast...

I'm using glass, but i plan on making different plates for each type of plastic. like ABS, PLA, are will print on a PEI covered plate. nylon and others will each have there own plate. or that's my goal...

~Russ

oh and you will be glad you have a heated bed. at least for some stuff like ABS you MUST use a heated bed. the OSD will be fully enclosed too so a hotter internal chamber temp. this is for large ABS Prints.

if your using only PLA you don't need a heated bed. 

~Russ

It's not commonly found on 3D printers, but a perforated print bed works like a charm and with magnetic mounts makes it easy to deal with (if only they would have used magnetic connectors too).  Almost impossible to have a failed print due to adhesion problems.

Just a thought.

I have seen some of theses, what size is the holes, what materiel is it made of, what can you print on it?
also hows it come off, dose the bottom of the print have theses holes and you have to sand it off?


yeah lots of unknowns about to be answered. 

~Russ

oh and i like the magnetic mount idea, i thought about it for the OSD,  but i don't like the magnets being exposed to such heat for such time, alnico magnets should be fine tho...
