wow those filament are about USD100++ per kg? mmmm self customization of wood color !!by redreprap - General
hee hee print a large band saw? i wonder, does printed ABS / PLA have similar youngs modulus like pine wood?by redreprap - General
hmmm r the guys from reprappro related to this site? they do look like similar logos though?by redreprap - Reprappers
not sure if theres a section on wood, but i thought id share the work this guy does here. take a look. its amazing and check out his marble maze stuff :pby redreprap - General
yea i wont know how good those china made stuff are. some were good. i bought 8 sample qty of cutters/endmills, i want to try them on the PCB mill i am making.by redreprap - Reprappers
errmm i just cant help wanting to mention .... you sit the machine before 5 yr olds? and they learn about 3d printing? seriously ... ow come one lol ! but you sure beat the replicator in price !by redreprap - General
hmmm interesting instead of wiring series or parrallel you could slightly mod it, draw out the logic pins DIR + EN + STEP, and "copy" this setup to another stepstick (out of ramps). so now using the same set of signals, use 2 stepstick to power 2 steppers. (i have not mod this myself yet, to do this you will need to prolly make it happen on a temp board outside the RAMPs PCB, like an external bby redreprap - RAMPS Electronics
speaking of lathes and such, there is chatter in yahoo groups about ceramic tool bits that last beyond metal ones. i wonder if anyone tried those?by redreprap - Reprappers
looking back at this post, it seems i have to "re-contribute" back for those interested in raster image to gcode [3roomlabs.blogspot.sg] or direct, if using kicad [3roomlabs.blogspot.sg] direct, if using EAGLE [3roomlabs.blogspot.sg] and misc notes on scaling if you do screen grab method [3roomlabs.blogspot.sg] and the PCB mill making is works in progress , with some stuff arriving from Chinby redreprap - CNC Routers, Mills, and Hybrid RepRapping

yes indeed, humidity is bad here around the equator regions. so i have kinda "sealed" off the room. the outside temperature is crazy these few days, i think air temperature is about 38-40 if you are to just stand there and "try" it lol ... madness! i also made a air blower, so that the inside of the entire room is always positive pressure. so far so good, it is also cleaner in the house now thatby redreprap - Reprappers
indeed, this "analogue" character of wood is quite a challenge. so i have kind of revamped my entire work space into a constant humidity workspace, it is almost always around 60-65% and a temp of about 27-28 degrees. im not much of a wood working person, its just something that i can use easily, transport home on 2 wheels, have enough tools to work on (just power saws, drills, etc. i dont haveby redreprap - Reprappers
the end product is gcode. i was trying to find an optimal way to get to gcode. i was too noob then LOL ! anyway i found a few ways, the manual ways from raster to vector to gcode, and then there was also the direct tool which now seems to work well. [3roomlabs.blogspot.sg] and the PCB2Gcode for EAGLE so now i have 4 ways to get to a somewhat final gcode using 2 types of schematic start point tby redreprap - CNC Routers, Mills, and Hybrid RepRapping
NICE !!! this is my incomplete machine, its made mostly from wood. ive only done up to 1x X-axis gantry, 1x Z-axis frame (1 out of 2).

ha !!! i have no idea what part are you stuck at, but this should give you some idea what i did to get things moving this is just 2D, some of what i did to get to gcode stage by using a picture (raster) --> DXF (vector) --> gcode.

viktor is evil, do not listen to him ... he prints stuff at subnanometer range .... no im joking, im blown away by his subnanometer printing in his basement. i think, accuracy of printing, secondary to that is the nozzle. cos primarily, your XYZ has to be able to move at at least 2x that resolution. cos print heads at the very least is about 0.3mm (300microns?) ... so you at least will need to mby redreprap - CNC Routers, Mills, and Hybrid RepRapping

O___O . . . would you be able to share a summary of your idea? hmmm i have a strange idea to swap a chunk of things but then again, i saw this ... its the actual tool change errr i think they call it a collet or something but because they make it for actual larger CNC, i dont think it will fit. it is going to be huge and heavy.by redreprap - CNC Routers, Mills, and Hybrid RepRapping
aarrgh .. i was reading something halfway ... got distracted and forgot where the original thread was ... has to do with the above, does anyone know about what bits they use for wood milling? is this the bit? they call this a flute right?by redreprap - Developers
