Hey Everyone, I haven't been having much success with my Sanguino 1.3b as I am unable to upload any firmware. I was told that the problem may have something to do with the bootloader and a possible solution would be to burn a new one to the board. I was also told the the most simple way of doing that would be to use a USBasp. My problem is that I'm not sure how to connect it correctly to the boby Leo94 - Sanguino(lolu)
Well for It complacently freezes I don't actually get a time out message. But I don't think your solution would work for me as I'm not using an adaptor with the Sanguino 1.3b board. But I'm going to try and burn a new boot loader when I get the USBasp to see if that fixes it.by Leo94 - Firmware - mainstream and related support
Oh good I'm glad it might me a fixable problem then. Thanks for the help. Oh and is the process of burning the bootloader (I'm planning on using USBasp) the same with 1.3b as 1.3a? It's just I cant find much information about 1.3b on the wiki. Again Thanks, Leo.by Leo94 - Firmware - mainstream and related support
Yeah, It does. Well at least I think it does. It has Marlin on it right now and it does boot, I assume for that to happen means it has a bootboader. Or am I wrong in thinking that. Thanks.by Leo94 - Firmware - mainstream and related support
Hey Everyone, For some unknown reason whenever I try to upload the firmware (Teacup or Marlin) to my Sanguino 1.3b board, Arduino just gets stuck at the upload. Everything seems to be functioning normally with Arduino but when it gets to the upload stage it just fezzes on that. The board came with Marlin pre-installed but I have been unable to connect to it using Pronterface so I trying to uploaby Leo94 - Firmware - mainstream and related support
Quick update, I tried to uploading the firmware with another computer but that didn't change anything, I still have the same problem.by Leo94 - General
Ok, I attempted uploading it a go without success. It compiled fine but when it got to the upload it nothing happened the progress bar just freezes at upload . I gave resetting the board just before the upload to but that didn't change anything. Oh and thanks for your help Andrew.by Leo94 - General
Oh yeah I edited the post because I using the wrong version of Teacup, sorry for any confusion. But back to what you said, I do have the gen 7 support package but it seems that I had the wrong board selected. I was able to compile the firmware with Gen7 with ATmega644P selected. But I thought that I would have to use ATmega1284P with the Sanguinololu 1.3b? Have I just configured Teacup wrong? Orby Leo94 - General

Hey Everyone, I'm obviously doing something wrong. I trying to upload the firmware to my Sanguinololu 1.3b board. I have tried using Teacup, Marlin and Sprinter as well as different version of Arduino but I keep getting errors when verifying the firmware before uploading. I'm pretty sure I have followed all of the steps correctly but maybe I'm missing something. Does anyone know what might beby Leo94 - General
Awesome, that did it. It all seems to be working fine now. Thanks a ton for your help Ben! I really appreciate it. Jack.by Leo94 - Sanguino(lolu)
Really cool. Very Interesting. Looking forward to Issue #2!by Leo94 - General
Thanks for the information logical_fallacy. I'm going add the ATX connector today, I'm glad its that simple or it may have been a costly mistake.

Hey Everyone, Just a few questions regrading the Sanguino 1.3b board. I recently received my fully assembled board and realised that I got screw terminal version by mistake (my fault), I want to be able to use a standard PC power supply. I'm just wondering if can simply add the connectors myself. Would I just need to de-solder the screw terminal and solder a Molex or ATX connector in its place?by Leo94 - Sanguino(lolu)
Hey everyone, I’m having some problems with my electronics, basically when I connect a Stepstick to my gen 7 1.4.1 board running the Teacup firmware it won’t boot. When I remove them it starts fine and Printrun detects the printer. It’s kind of strange because everything else seems to work fine. Anyone got any ideas what the problem could be? Is it the Board, Stepsticks or Firmware? I don't knowby Leo94 - Controllers
Hey Everybody, I have a question about power supply's. Basically I'm trying to get my ATX24 PSU which I salvaged from a old computer (I have tested it in my PC and everything work fine) but I cant get it to activate when it's connected to my Gen 7 1.4 board, the PSU is on I just need to activate it. I have tried adding a load to it by connecting 12v light bulbs and a disk drive but it wont actiby Leo94 - Controllers

Oh good because that would have been a pain. Anyway I have never even put it in because I can't complete the testing, I don't want to break it.by Leo94 - Next Wave Electronics Working Group
Do you mean reomve the whole socket for the ATmega??by Leo94 - Next Wave Electronics Working Group
Yeah that makes sense now I think about it. Well I did what you said and followed the track and I removed C19 and the problem was still present so I then removed the wire bridge which is further up the track and the problem is still present. I have checked all my soldering and I cant find any problems especially around the area between C19 and the bridge. So from what I can tell there short is sby Leo94 - Next Wave Electronics Working Group
I desoldered L1 and the problem seems to have been fixed So what do I have to do now? Do I juat need to replace L1? Thanks for your help by the way.by Leo94 - Next Wave Electronics Working Group
I think I may have found the problem! But I could be wrong. From what I can tell some of the pins of the jumper headers are connected to ground. I'm assuming that's the problem. If so how can I go about fixing it? Because I just cant see how they are connected to ground. The pins in question.by Leo94 - Next Wave Electronics Working Group
Oh okay then, don't worry about it i'm just going to have to do what Traumflug said then. Thanks anyway.by Leo94 - Next Wave Electronics Working Group

Thanks for your reply. So I measured the resistance between the stand by LED and ground and I couldn't find any evidence of a short. It just shows 980 ohms which I think right . Everything else also seems to be ok to. Leo.by Leo94 - Next Wave Electronics Working Group
Hey everyone, I have been having some problems getting my electronics working. Okay, so I have just finished soldering the main board today, everything looks fine but when I connect it to the power supply all that happens is the standby LED faintly flashes. The PSU also makes a very faint clicking sound and the power LED on that also flashes. It seems the problem is not with the PSU because itby Leo94 - Next Wave Electronics Working Group
