Re: Changing the Fuse settings to a 1284p using an Arduino Uno as ISP - 12 years ago
Just found out thatvit gives the same exact reading, even if my 1284p isnt powered.by theruss007 - Controllers
Re: Changing the Fuse settings to a 1284p using an Arduino Uno as ISP - 12 years ago
Well ive given it a try. Id give a more detailed description but im on my phone right now. But basically, idk if im gettimg results back, all the fuses say they read as 0. Iand itsays the the device signature is expected as 1E 97 05, yet it shows 0x1e950f. Does that mean it reading from the chip at all? The command im putting in to read the fuses is avrdude -P com 8 -c arduino -p m1284p -U lfuse:by theruss007 - Controllers

Thanks guys for the replies. I'll give this a try later tonight and let you all know how it goes.by theruss007 - Controllers
Changing the Fuse settings to a 1284p using an Arduino Uno as ISP - 12 years ago
HI All, I have a Sanguinololu that uses the Atmega1284p, and am having some trouble with. The endstops will not register and the motors will only spin in one direction no matter what settings are changed in firmware(I'm using Marlin, btw). After some searching I believe the problem is that the JTAG fuse settings for the chip are wrong, and that it must be disabled. I never uploaded the bootloadeby theruss007 - Controllers
USB/Pronterface Connection issues. - 12 years ago
Hello, I am using the 1.3a version. I am having connectivity problems with my board. Sometimes with the USB and sometimes with pronterface, but I do not know if the to are related. I built the board a few months ago, and did limited testing, and then set it up for a while. After trying to reconnect it a week ago I kept getting a flag from Windows saying the USB device was not recognized. I upby theruss007 - Sanguino(lolu)
Re: Cheapest Electronics - 12 years ago
I'd recommend a Sanguinololu. That's what I'm going to use. Putting it together wasn't all that hard(just make sure you check and recheck your soldering for the FTDI chip, it will save you alota time trying to figure out what;s wrong), but I haven't actually tested it's performance when printing yet. It is relatively cheap. So my vote is on that one.by theruss007 - General
Re: Can't connect ot Sanguinololu - 12 years ago
I tried that and still nothing. I eventually decided to re-check my soldering on the FTDI, and turns out I had pins 1 and 2 soldered together... I fixed that, did the echo test and it worked. I then uploaded Marlin with no problems. Even connected it to Ponterface. Turns out it was something stupid on my part. But thank you guys anyways for the help.by theruss007 - General
Re: Can't connect ot Sanguinololu - 12 years ago
After no luck and deciding to go over things in more detail, I took out the Atmega 1284p from the board to see if the error changed. It didn't, which led me to think maybe it was the FTDI. I checked it by connecting the RX and TX oins and when I sent characters from my keyboard I got nothing. Not only that when ever I had the jumper connecting them, I would get random characters. It looked like pby theruss007 - General
Re: Can't connect ot Sanguinololu - 12 years ago
I also just downloaded the Ardion 1.0.1 IDE and after I get a chance, I'll try it out.by theruss007 - General
Re: Can't connect ot Sanguinololu - 12 years ago
Glad to know the chip isn't fried. I'll try messing with the Baud rate some. I've already don what the Marlin firmware said to do. Originally the Sanguino didn't show up in the Boards selection, but after I followed the README instructions, it showed up.by theruss007 - General
Can't connect ot Sanguinololu - 12 years ago
I'm trying to upload the Marlin firmware to my Atmega 1284p which had the bootloader already installed on it, on my Sanguinololu. At first I was getting an error. I can't remember what the error code was. But it changed to the: avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51. I tried changed the avr.config file in the arduino-0by theruss007 - General
Re: Sanguinololu Programming Help - 12 years ago
The 1284p already came with the bootloader on it, so I have no need for the ISP. After reading all your comments, I guess I'll give the FTDI soldering a go. Worse case scenario I mess up and have to hack something together, like I'm trying to do now. XD I'll check out that tutorial and others. Thanks everyone for the replies. I'll let ya know how I do.by theruss007 - General
Sanguinololu Programming Help - 12 years ago
I recently ordered a Sanguinololu to be the brains of my 3D printer. Unfortunately I am unable to solder the FTDI (surface mount) chip that comes with it. So I have been looking for an alternative solution to programming the firmware, in my case Marlin, onto the Atmega 1284p. I don't want to buy a FTDI chip if I don't have to. I might even get around to soldering the one that came with it eventuaby theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago
So basically, if I connect the Step, DIr, and Enable pins to the corresponding pins on my Easydrivers, everything should work the same, correct? Btw, that's the Sanguinololu schematic above.by theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago
It is, indeed my first go. And seeing as how it's a low price on ebay, I think I'll go the Sanguinololu kit route. But I think I'll still try and use the Easydrivers with it, if I can. I just don't won't them to go to waste. XDby theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago
Now that sounds tempting. I could use the Easydrivers I already have, and use the Sanguinololu. I'll look into that as well. Thanks for the idea!by theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago
Well, if the perfboard was the choice I was going with, so that's great that you think it'd be the cheapest. XD And I know there is some risk, but I'm confident I can do it if I take my time...hopefully. Besides I think I'll like the challenge. Granted the RAMPS board does make it easier, but it looks to me as if you'd have to pay for the drivers anyway, and the board with components. All seemiby theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago
Honestly all it looks like when ever you buy a board is the Stepper Driver boards, various pin connections, and resistors. (I'm oversimplifying of course.) That being said, I already have the Easydriver boards, and resistors are certainly cheap. lol I'm most likely missing something???, but it just seems cheaper to build your own electronics.by theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago
I checked the amperage ratings, and all and they were good. BUT, i notice you said it would be cheaper to go with a RAMPS board...I was under the impression that it would cost more to buy it than to go the homebrew way?by theruss007 - General
Re: Marlin Board Selection for Homemade Electronics. - 12 years ago

Marlin Board Selection for Homemade Electronics. - 12 years ago
I'm building my own 3D printer form scratch. I'm going to use the Easydriver boards for the steppers, and hook up the various electronics to the Arduino pins. The Marlin firmware allows you to choose the board you are using, and I noticed in the Config file there was a selection for a board "99." Is this the "board" you would use if you are using homebrew electronics? and if not, is there suchby theruss007 - General
