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

Hello Rob,
yes i've seen Oshpark, there price is not expensive.
Its a good opinion to double check the diagrams.
I wish you verry mutch succes, it looks all verry good!!
Pierke
P.s.:i'm looking forward to your next post!
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 the stuf off, just taking things i dont need/want off so theres fewer components
tiny bit left in the main diagram is the thermocouple or thermistor part.
i cant decided if i should have a thermistor or thermocouple. i was going to use a thermistor, but i havent been able to find one suitable for the temperatures or thats easy to mount to the heating block.
i think ive found a type k thermocouple with may do the job, link should be below, any suggestions on whats best?

Hello Rob,
i think that the thermocouple is the way (as Farnel) is to big, the mass is to big for a fast interaction with your platine. I you wish , i can send you a few meters of k thermocouple,so you can try it out. (for free!!)
I try tommorow take a picture of a usebal thermistor from...take a look: MBE Extruder v9 - Single - QU-BD 3D Printer CNC Mill Store

Hello Rob,
take a look at your mail.
Pierke
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

Hello Rob,
i think that it is a good choice, its the same as Electrical Components - QU-BD 3D Printer CNC Mill Store, only this price is cheaper.
Pierke
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 schematics are correct?
rob
this is what i have so far
rob
I'v read elsewhere that some guys use a temp. controller from Velleman Kits.
Nice work Rob,
i can't tell you that all of these are correct. Maybe is there someone that make pcb board with an engraver (for the fist test)
I have an engraver, but i dont now how this work with Gerber data.
Pierke
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 can test it easily before making the final thing?
rob
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 though since ive not got any money to buy anything, still job hunting, so probably not gona be able to do anything for a bit. may have a look at the cad model and see if theres anything i can improve, apart from that i think im just waiting on a job.
thanks
rob
