Hi, this is raj from mumbai.I made mine six months ago.however I am not able to get the raw material for printing,ie.ABS /PLA in 3mm wire form at normal cost(Amptronics is offering Rs 2500/Kg which is too high).Can you tell me where you are based in India and from where did you get raw material?by colourz - India RUG
Hello, I've already made Gen7v1.2 successfully. just waiting for ATmega644 and pololus from Traumflug.Then snap and roll.its very easy and simple board to make by toner transfer method.thanks to Markus Traumflug for so simple design. best of luck. Rajby colourz - Next Wave Electronics Working Group
Yes ,it must be the heat from the regulator because the power led now glows and I've been long enough with general electronics to know what happens when the polarity reversed to the electrolytics.pop goes the weasel. Anyway thanks guys.now I am making monotronics from the scratch.no more will to make gen3 work.this time no more mistakes as I learnt a lot from you really,really helpful guys.will kby colourz - Reprappers
Hi Victor I checked everything as you said.now what I observed is the 5v regulator is getting near red hot as soon as applied with external supply(only 6v 800mA) as well as both the 100uf electrolytic capacitors on either side of the regulator. any guess why? I checked circuit for shorts.clear.made the pcb as per wiki instructions. RAJby colourz - Reprappers
Thanx guys After some forum searching found out that Victor is right. AVRISP does'nt power up the board.you have to use external +5v .though it didnt solve my problem. even when i connect ttl-to-usb cable ,nothing happens.no power led! nada zip.by colourz - Reprappers
Ok,I'll explain it again. I am trying to upload bootloader in to the self made EC v2.2 . I connected avrisp to the ISCP of the Ec. Plugged in the usb to the pc. Now there is a little flicker of power led on the avrisp thats all.there is absolutely nothing on the EC board,no power,no debugging leds lit. I've checked the orientation of the leds which is fine. Can anyone shed light on what mistake aby colourz - Reprappers
thanks brnrd, sorry I forgot to mention that there is not even the power led on the EC board is coming up.I checked the orientation of the led and it is correct.and I was trying to burn the bootloader.by colourz - Reprappers
yes you are absolutely right on that Markus. May be I didnt think in right levels.got carried away by the frustration of not being able to make my electronics work whereas the things are so simple for others.sorry to bother you people by wasting your time answering me when you could have been helping some sorry a** like me. anyways thanx RAJby colourz - Administration, Announcements, Policy
I am sorry.I thought that reprap is all about helping people make their own 3d printer which otherwise would be the stuff for geniuses.yes you are right ,why would any smart fellow stay with the old set of stuff once he got the whiff of doing things?(albiet may be its from the help of reprap people )by colourz - Administration, Announcements, Policy
Hello everyone, As I can understand and very much appreciate the hard work you people are doing,what I dont understand is why there is not a single perfect working set of cartesian bot with electronics and all the required software/firmware? How can people like me make a reprap without getting stuck at somewhere? I understand it is imperative to develop newer versions for the sake of advancemenby colourz - Administration, Announcements, Policy
HI Again when I connect the serial cable to the EC board,nothing seems to happen.no debug light on the board,nothing on the ftdi modulu or the pc. the EC2.2 gen 3 board was mae by me. from where should I burn the bootloader on the atmega168? Nothing happens even when I connect the programmer to the ICSP on the EC. Help will be much appreciated. thanks Raj.by colourz - Reprappers
If so,from where do i upload the firmware?from the mobo's 6 pin serial headers or sanguino's? whose reset button is to be used? did anyone tried this before? as the mobo was made by me ,I dont want to solder the 644p qfpn before checking whether the mobo works or not.by colourz - Controllers
Ok another question can I run the gen3 mobo without the atmega644p qfpn soldered onto it but the sanguino breakout board plugged into the mobo headers?by colourz - Controllers
righto! that makes everything clear to me. thanks Nopehead,you seem to be the one with all the answers.by colourz - Controllers
Hi everyone, On gen3 mobo1.2,the centre track of the spdt switch goes to the 20 pin molex connector's bottom line 4th pin.and it is not connected to anything(atleast as per mendal wiring on diy wiki).Then how will the switch work as it should be?pardon me if Iam being stupid.by colourz - Controllers
Hi Markus, they are gen3 electronics,sanguino mobo v1.2, EC 2.2 ,STM 2.3,windows7,reprap build 20110509,arduino 022,fdti-usb to rs232ttl board some chinese programmer(proisp7),(as no other programmer was available within my range). when tried to programme the sanguino with firmware,the arduino ide says'uploaded sucessfully but verification error' thats all nothin specific. And I became smart andby colourz - Controllers
Hi Traumflug, I am really surprised.however thanks for the answer.in first place i sought someone from India as i was afraid of the postal charges. it surprises me how helpful u people are. I made every bit of the mendel with only home tools including electronics but now i am not able to program them.thatswhy i am asking for whole preloaded electronics. thanks once again .i'll search for the peopby colourz - Controllers
Thanks Traumflug but what about the postage charges? how much would it cost me Rajby colourz - Controllers
IS There anybody in india who can provide fully laoded Gen 3 electronics? so that they can be used off the shelf?by colourz - Controllers
Hi, Do not want to repeat the same question,but have no choice.I too stuck with the same problem of stk500_getsync(): not in sync: resp=0x00 stk500_disable(): protocol error, expect=0x14, resp=0x51 And tried all the combinations with reset switch .Using the same cable and board which was sucessfully used to load bootloader.please help me,I m using win7,and a prebought sanguino (only)breakout bby colourz - Reprappers
hi everybody,please help me regarding this... I've made my own mobo v1.2 but did not solder only the atmega644, instead i plan to use a sanguino board I bought premade,now the question is -can I pin the sanguino onto the mobo in the female serial connectors without the atmega644p 20au on the mobo? If so ,to what should I connect the ttl to burn the boot loader,to the mobo serial or the sanguino sby colourz - Sanguino(lolu)
