hi all, not really done much recently, finished some prototype boards that im gona use before designing/building the mother board, found all the components for them too. cant do any building yet...

thanks pierke
still not finished the motherboard though, i need to find parts i can use
since its based on the arduino mega board would it be a good idea to make a prototype in small sections so i...

this is what i have so far

i liked the price of it, much better than the thermocouple i originally found.
ill start uploading some of the wiring diagrams and board layouts i have.
anyone know anyone that can tell me if the...

found a new thermistor to use, its one used in reprap printers so i know it should work
i just need to change the schematic to take them then thats them all done, i think

thanks pierke, hopefully i can get the electronics finished soon so i can start buying stuff
i think most of the diagrams should be right, found some on internet which ive been able to copy alot of...

im guessing you mean pcb.
i cant make them myself, ill probably use oshpark to get them made
ill get the diagrams and layouts checked before i get anything made though

well i was going to but the arduino and boards ide need, but when i was making a layout for the navigation and lcd panel i got a bit carried away and changed my mind and decided to make layouts for...

not done much on the design ive got recently, but i hav made some progress with electronics.

ive decided im going to use the arduino electronics. this way i can personalise it to my design and...

at the minute ive got some custom sized ones, id'e have to get them machined, just brass tube i think i put it. so ill try it with 2 short ones in either end of the block and just one long one. if i...

hi all, thanks for all the feedback, not been able to do anything on the design recently
had to get cracking on with some revision for uni, want to try and get a little bit done on it this weekend...

just had a look at moving the motor for the x axis too, decided that its current position is the best position i can get for the most range
i couldnt think of a suitable way to mount the motor easily

did some work on the z axis today.
again using sheet metal, ive changed to 2mm throughout the design. not sure if it will be able to take the weight of the models though
uses a nema 17 linear motor...

ill make sure to get them bored slightly bigger than the shafts. i looked at them, when i modelled them they were too big for the size of some of the sliders, and the bushes were easier to mount. ill...

i thought if i used bronze bearings it would be cheaper and ide be able to make the design more compact

ive tried adding the photos again:

hi
so i was looking at the makerbot replicator 2 and fancied having a go at designing my own printer. ive pretty much finished a solidworks model. dont want to do anymore until ive had some feedback...

i couldn't find anywhere that sold the aluminum extrusion in the UK so im using box section for the rails.
ive designed most of it. im then going to have some round rails and a lead screw for the z...

do i use 11 or 12mm bolts?

got the link working, just removed the / from it, thanks

vcooney, thanks for the help, i wanted to open the link you added but its not working.

thanks for he heads up rodder, it definitely wouldn't have been something ide check. would i be best buying...

hi, im wanting to build a plasm cutter but im going to design the whole thing instead of buying the mounts from nosleep studio. i was wondering how the aluminum extrusion is bolted to the metal...

does that include the one i just did?

i decided not to bother with my first idea.
used the other easier idea.

i made a 3D model of it. but in still having problems finding a long lead nut.
with what the parts ive been able to find...

yeh that was my other design. i can get a pulley and machine the diameter bigger.
but with the size of nut i have found i cant get a bearing onto the nut and be in the MDF.
is it possible to get a...

i started to think of that just before. tbh i dont really know.

another design i had was a round nut and a pully fit over it, with a cap head or grub screw to tighten it onto the screw. with...

right im designing a machine out of MDF.
instead of having a rotating lead screw, im wanting to have a rotating lead nut
ive made a design, but im not sure if it will work. or if its too much.
...

hi all
i started designing a CNC router, im gona make it out of 18mm MDF. ive got the 3 axis designed. but i could do with a router to finish parts of the design off.

i was hoping to be able to...
