o.o ... so you guys make alot of stuff using reps?by redreprap - Singapore RUG
tnx, i will sure dig for more help from pros in this forum ! yea i did though of just grabbing the original reprap kit from UK, and prolly make a bigger 1 from using it. then i though i had tons of time on my hand and the size of that unit was not quite what i like in the end build and it will just cost me extra, so i go the way of a build from "scratch" by looking at tested models. i think iby redreprap - Reprappers
i did some paper planning for a bed about ur size. its a huge huge thermal engineering thing !by redreprap - General New Machines Topics
ok now that makes sense, tnx nophead so a heated chamber to reduce warp? or add in "legs" below to model to absorb the warp? if the model is heated to 50c, will it mean better adhesion for the build as the extruder do its deposition? if this is better, sounds like a mini "hairdryer" connected to some air temp sensor could workby redreprap - General New Machines Topics
this is what i am planning to make. it was suppose to be 1x1x1m but i cant fit that in my bedroom LOL ... i think actual should have a small X (800mm?) but higher Z (1200mm?). it is based loosely on cartesian, and some inspiration from ultimaker, bits here and there. i have yet to start, still gathering proper parts . i have dumped some money in getting 20 steppers to test even LOL !by redreprap - Developers
you should consider cartesian. you can have option to mill wood with proxxon. i know my balsa wood planes use wood "D i m going to make 1 like a cartesian ... i think it will take me 3-6 monthsby redreprap - Developers
this is the plan on PAPER ...by redreprap - General New Machines Topics
wow nice effort there ! im about doing something similar to yours from scratch as well. i initially got very excited seeing how well the ultimaker prints, then i realised what i really wanted to try was something big, so i intended to mix and match several ideas. i am currently moving more in the direction of the cartesian. and yes i order most of the precision parts online like bearings, timingby redreprap - General New Machines Topics
wow nice, i am another crazy guy going to try to make a large printer. due to my bedroom limitations, i am in the process of building a RR machine that is under 1m tall, x-axis just under 1m, and Y-axis at about 580mm. i based my starting idea from cartesian. and yes i could be using a 4 tower method. frame rigidity could be a concern at this stage, and i have yet to commit to parts. except theby redreprap - General New Machines Topics
any 1 alive ? rep rapper in SG? happy post N-day !!!by redreprap - Singapore RUG

sooooo ..... there are reprappers in SG !!!by redreprap - Singapore RUG
i am kinda confused re the color of the wiring, but electrically when you guys say series, you mean as in --> motor A coil A start --> end --> motor B coil A start --> end .... and so on for coil B ... am i right ?by redreprap - General Mendel Topics
tnx for the link ! hmmm this photo-active resin certainly is amazing. very nice resolution esp for miniatures. but ima keep my hands on PLA food safe stuff for a startby redreprap - Reprappers
is there a wiki on B9? or it has another root name?by redreprap - Reprappers
i am half way around the globe, and i am planning my first reprap. i dont think there is any reprapper in south east asia LOL !!! i have been studying the cartesian model with much excitement. i received my RAMP 1.4 board yesterday. arduino is somewhere lost in the mail system plus a couple of other stuff LOL !!! i have spoken with some filament suppliers down at new zealand. and i cant sleepby redreprap - Reprappers
i see, cost of material is higher. but i am guessing the finish must be very smooth? how does material deposition work on those?by redreprap - Reprappers
ah ... something like UV cured .... i cant find any info on the material cost ... like 3mm filaments are about 40/kg +/- ...by redreprap - Reprappers
i see ... so irregardless of what the tool is (extruder, milling, laser, etc) if i can make the XYZ mechanisms to be able to resolve higher resolution, the more "useful" it will be ... so it will be safe to say, by adding a ratio to the generic stepper motor (hopefully no backlash), a 3 to 1 reduction would definately improve resolution in sacrifice for speed. so after this to increase speedby redreprap - Reprappers
am i right to say the smaller the extruder hole the more fluid you need your filament to be and thus the higher the temp?by redreprap - Reprappers
i am new to reprap ... i think you mean a software to read gcode and spit it out to the arduino, which needs a firmware? try search reprap wiki and look for the 2 things : software and arduinoby redreprap - Reprappers
im new to repraps. when you say steps per mm, it is a theoretical calculation based on the knowledge of your equipment or you physically measure? or a mix of both? so say if my Z axis is based on 200 steps/rev and it does 1.5mm on a machined thread, i should program the firmware to read 133.333 steps per mm right? i have yet to recieve my arduino, but my ramps board is already here. looking atby redreprap - Reprappers
ok ima noob question this ... all reprap have this thing call layer resolution, like 0.3mm? or how is this parameter realised? i know many users play with thier machine to fine tune heating and stepper performances to come to a certain speed adjustment and resolution refinement. i am wondering how can a slicer software put its weight behind this part of the process.by redreprap - Reprappers

hmmm yum yum ... digital calipers ... *scurries off to ebay again* yes the first few hundred listed in ebay seems all from the same factory LOLby redreprap - Reprappers
well i've been reading from what users seem to imply, netfabb has a good algorithm going in terms of control software and print "behavior". i am inclined to think that they did some research on how should a additive print head behave in an active print or something like that from their larger pro applications and from their algorithms that kind of re-analyzes the printed shape in a different mannby redreprap - Reprappers
wow, wad an episode, to me ive been fiddling in electronics for many years, anything that goes above 12V 1A (12watts) in small packages can burn stuff pretty quick ... the 12watts have to go somewhere when i was looking at the PCB heater beds, i was quite prohibitive about the way it should be run ... too high a wattage me thinks in many ways.by redreprap - RAMPS Electronics
i have also been to the alltronics site, they no longer have the higher torque rating NEMA17s.by redreprap - Stepper Motors, Servo Motors, DC Motors
