I am in the process of building a large printer myself, I will be using 16mm rounded bar with support, hardened, it will be a prusa i3 kind of frame, but large large going to use a .8 or .9mm nozzle i cannot wait to print a large object, the gears you print are awesome art! Id happily hang something like that on my wall.. The other day I paid about $100 per large vase that is made from a resinby nechaus - Developers

Quotebobc RAMPS works quite well with external drivers, although some config may be required. Quite a few people are using some variant of the Toshiba driver (TB6560 etc) which can handle 3A and more for about $10 per axis. I am looking at how to support this config with a interface header board on the RAMPS. Thank you!!!, I will certainly look into those ones, 3amps would be ideal! Here areby nechaus - Reprappers
I am quite confident in preventing sag, I have a few ideas to prevent this, I will be using 12mm steel round hardened steel for the linear movement, However it may change... I guess worst case, I build it up and end up having to make it a smaller printer in the end... The size i want does not seem to be difficult to achieve, You are getting me interested in cnc tho, I will take a look at it sooby nechaus - Reprappers
I actually plan on not using a heated build plate but just a heater build environment, Will be predominantly used with PLA. A cost of electricity using such a large heated plate at 100c will be a bugger, So i thought ill try this instead. I would prefer to use ramps, So if I will have to go down the path of cnc stuff, I will need to read and learn more... Trying to avoid this until I build a dby nechaus - Reprappers
check it out, on board camera, Auto stop when filament runs out... some pretty cool features with astronomical prices temp controlled chamberby nechaus - Reprappers
So iv been briefly looking over it, The common stepper drivers can do 2.2 amps with forced air cooling... So it will make sense to use 24 volts with this systemby nechaus - Reprappers
I use borosilicate at home on the printer, and in the lab at work, It is very durable, Can withstand reprap temps easily...iv used normaly glass before and it warped on meby nechaus - General
Hey guys, I am building a large scale printer, it will look similar to the prusa i3, 400mm-x x 700mm-y x 600mm-z So easy to build i love it. been working on ways to stop droop on the print bed, using 12mm smooth rods, may need to go with rails, not to sure yet I just wanted to ask you guys from first hand experience, Whats the most powerful electronics kits? I need beefy stepper drivers, Wasby nechaus - Reprappers
Normally when i get really bad grinding of filament, Its normally a hotend issue for me, junk in the hotend or something..by nechaus - Mechanics
I dont think it will help that much, Why add dual motors when you can just use one and dual hobbed bolts? one nema motor is certainly strong enoughby nechaus - Mechanics
QuoteAntslake Well I did several prints with it, including a 10 hour print. I am sure retraction suffers due to bunching of the filament in the 3mm tube. After more than 15 hours of printing, it finally jammed, I don't know why. But it worked for the most part. Got to get me a 1.75mm hotend..... sounds just like how mine behaved.by nechaus - General
I have done it b4, sometimes it jams, sometimes it does not, It will depend on the hotend, on the buda I just got a leakby nechaus - General
I think you can do it direct drive, You just need to make sure your feed system is tuned, Hotend is in good condition, no junk in the hotend, Fan used on the top part of the hotend if your using PLA.. make sure its all dialed in. I personally prefer the geared setup.. Id rather have my hobbed bolt eating the filament if their is a jam opposed to my motor stalling and generating heaps of heat.by nechaus - Reprappers
So I got some Nylon Filament from Bilbycnc.com.au 1.75mm Stuff under their special filament section on their site. I had it for a number of months opened, Tested it on my bowden system when I first got it, it would find gaps and places to escape, put it aside for sometime... Changed my system to direct-feed.. Worked on the 3mm ptfe liner on my buda, but it was leaking, Changed the liner to 1.8mmby nechaus - Reprappers
Another thing, Make sure all axis movements have smooth movement.. Once i used adhesive spray and some managed to get on my smooth rods on the x axis, It became extremely hard for the motor to move it, only after a few prints, the motor got very hot and started to skip when i noticed it. So i used acetone and cleaned and re-lubricated, smooth as now.by nechaus - General
i use fans on my X axis motor, and Y Axis as they are constantly moving. If your Z gets hot the current needs to be adjusted Mine get quite warm without fans, I used my printer for like a year without cooling, Now i have fans for my motors, Hotend and prints if using pla. some people dont like this but i do it just to get the most performance, It uses slightly more power, and creates more noiseby nechaus - General
its so annoying having a jamming hotend, it was worse for me like 2 years ago and i was just getting into reprap, i thought all sorts of weird stupid things to why i had inconsistent flow Budaschnozzle is great, easy to clean if you get junk inside, I just want an e3d already tho.by nechaus - General
I changed to a cartridge heater and has never fried on me, taken to like 300c at one stage, works perfectly, my last one like yours was 7.5 or 8 ohms cant remember, but google itby nechaus - Reprappers
is there a feature of a host program that logs total hours of printing and filament used?by nechaus - General
filtration on the printer sounds good, I need to get some dehydrators as well, one for food and one for filament.. this is for 3mm setup and it actually about 2.5mm-2.7mm I was setting first layer to 300% layer width under advanced setting in slicer This is the filament Maxpower 333605 Residential Grade Round .105-Inch Trimmer Line 690-Foot Length List Price: $23.99 Price: $23.14 & Fby nechaus - Reprappers
I have finished printing with 1kg of trimmer line, 3mm, dried It heaps, all printed at 250c-260c pushing the hotend to the limits.. still going strong now .. anyway, I wasted lots of plastic but had some fun, I printed many things, extruder gears, vases, higher temp parts, parts, lots and lots of bushings.. No heated bed used adhesive spray to hold the part down to prevent warping 10-15mm brim 2by nechaus - Reprappers

I wonder what the most efficient setup for a heating bed is? im thinking it would be like some kind of bed that takes a long time to heat up and retain the heat? I almost was going to take my printer outside the other day and let it sit in the sun to see how it would go with printing..by nechaus - Reprappers
I use to hate all cordless tools, anything with nimh battery chemistry was so crap in my opinion, all the lithium tools are pretty good these days, even Ryobi is good, can easily hack the battery packs and run higher capacity for really cheap price, print out a battery housing too.. for e.g. a 18 volt Ryobi battery rated at 2.8ah cost me at my local hardware about $70 to $100 I can get a 5s zipby nechaus - General
Im just terrible with the handsaw.. So is the cordless as good as the plug in versoon of the dremel?by nechaus - General
Yep it will do the trick.. set it to hi speed.. Check out thingiverse they have a few handy things you can print... you can turn it into a bench saw to get str8 cuts once you print out the jig.. great for quadcopter arms I foundby nechaus - General

meanwell ones are very good, nice body, i have a couple laying around here but they are more expensive.. honestly hobbyking is not that bad, iv had some dodgy products in the past like portable usb chargers that never actually worked and the warranty process is more annoying so i just took it as a small loss..

another thing i tried the other day was chopping a small piece of nylon, put it in mineral oil at like 150c, if it has lots of moisture you will hear it pop as the moisture leaves the piece. iv been drying this trimmer line heaps lately, its summer in australia, been getting some aluminium foil, getting a small spool and puting it in my oven at 100c every 2 hours or so, id let it cool, you canby nechaus - Reprappers
