I think he is talking a full IDE debug enviorment, with the ability to set break points, interrupt a running program and examine variables in context etc. With the primative IDE for the Ardunio you end up with verbose output statements to prove chunks of code are running, etc.by freds - Controllers
Hey Chuck Since we solved your problem, how about re-editing your orginal post title, adding the word fixed or no longer disgruntled? Given your mixed enviorment and being a beginner at this it easy to understand the communication problems.by freds - Controllers
Here you go, looks like they also finally got around to updating the instructions for the structure change that happened in the Arduino 17 release.by freds - Reprappers
Hi Spacexula I have thought about responding to this thread for a couple of days. Thank you for the contributions to our join project! Enabling other people to contribute is very positive.by freds - General
Wow I never expected this thread to reach it's second page. I hope I do not get banned here. Ok I have to say this thread is not very productive, what is the point to come to some conclusion and shut down RepRap development all over the world? No creative effort is ever wasted as some portion of it will be reused for something of value, at some point in time. So splitting hairs about whether itby freds - General
Hi Charles On the 1.2 boards the enable signal is tied high, on the 2.3 boards it is an active low signal. Which actually makes sense, I.E. Broken wire brings everything to a stop.by freds - Controllers
Using pin 0 for direction step makes sense as the boot strap firmware blinks the led when the processor is reset or during power up. So since the firmware is also not exercising the step line no physical movements take place, essentially a functional no operation.by freds - General
Yes rather then taking a 15 degree cut, take a five degree cut. I have read the problem with high fractional micro stepping is sometimes its an average in that the motor is not guarteed to move.

I was wondering about that, reduce the angle so you have more steps per movement? Arvin Wrote: ------------------------------------------------------- > The wood dowel has been canned.

Hi Lond From the picture it looks like you have a USB driver board between the PC and stepper board; I assume you have by passed that and wired the stepper motor driver board to the sanguino motherboard? If so it should be a simple matter of adjusting the firmware skectch for your configuration. Things that will come into play are step and end stop polarity.by freds - CNC Routers, Mills, and Hybrid RepRapping
The 2.x boards have the enable signal the opposite of the 1.2 boards so if the firmware is setup up the newer board then when it enables the steppers it is actually disabling. There's a define statement that controls the polarity.by freds - Reprappers
They totally changed the structure of Arduino in release 17. Since the Sanguino is not officially supported by the Arduino team the layout and libraries for Sanguino need to be revised. Something the makerbot team hasn't gotten to yet. So until they do release 16 is the latest that you can use.by freds - Controllers

Hi Brian Depends on how badly it is "coked" up. Soaking overnight in acetone somethings works. Though if off on the chance you created your own nozzel, just run the drill bit though it again.by freds - Mechanics

By over-temping you are probably clogging your nozzle and may have destroyed or malformed your thermal barrier. It's a common beginners mistake to keep upping the temperature. I kept doing the samething on mine, by not starting to extrude until it reached 240 and since my setup might have been off it was probally at a higher temperature so it kept jamming. When I started trying temps around 220by freds - Mechanics

I don't have the post, but one makerbot user redesigned the biggest part to be printed into two sections and then glued together.by freds - General
I was wondering why we don't stick with the NEAM 23 we used for the darwin and use shaft couples. That way you could move the three axis motors to another machine, mendel for reprap, McWrite for light milling PCB routing, etc.by freds - General
Hi Rather then try to cordinate firmware on two seperate computers. Use the serial chip in bit banging mode.by freds - Controllers
Interesting layout, but you have to confine the fiber so that it will not spill off to the side.by freds - Mechanics
Hi Matthew I am curious about the heat sink that you are using on the stepper chip, is this a industry standard part?by freds - Denmark RepRap User Group
Not yet there's a video to using version 17 on the mac. They changed the layout after version 16. I had to switch back to sixteen as I in the process of creating libraries and didn't want to deal with the differences.by freds - Sanguino(lolu)
I was thinking that the build could be in two phases, outer shell which you do in .5mm fiber and inside sparse fill with a second extruder at 1.5mm. Thoughts?by freds - General
The 5v cable can also be used via bit banging to program raw AVR chips to get them ready for use with the Arduino IDE.by freds - Controllers
Triffid_Hunter How about a picture of your heat sinks?by freds - Controllers
Ahh don't send any money unless they can show pictures of orginal parts, heck taking quality pictures is a heck of lot less effort then actually producing the parts.by freds - For Sale
Hi Steve There are always a number of people looking for a european source of the semi standard PCB's for generation II and III boards. It's all open source so maybe you could be a supplier, run our boards in odd left over spaces of other runs. Have your "Challange Dave" contibute a re-design of the layouts?by freds - Controllers
Dang a six dollar chip on a board with replaceable chip, verse hours to try and shoehorn code growth into a tight area, seems to be a win/win solution if you can double the flash and ram. If you are international and can't order from Adafruit. Since you have this board and that you can bitbang the appropiate bootstrap into it.by freds - RepRap Host
