Englewood, Make sure that you have set the correct property for your comms. In the property window, set the com port to COM4 instead of /dev/ttyS0 (which is the *nix name of a com port) Also, you mentioned this error you have in a prwvious post # An unexpected error has been detected by HotSpot Virtual Machine: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6930b83b, pid=1504, tid=2448 .by Joost - RepRap Host
I have had some trouble finding a place where they sell JB weld and was wondering if this exhaust repair product could fulfill the same function (i.e. fixing the nichrome/thermistor to the extruder parts. AFAIK, a car exhaust is quite hot, so this could be OK, but I can't find much info on the product (max temperature). I asked the manufacturer, but figured I might as well ask here.

Hey Jonathan, I did some searching on the j3d site, and found that the j3d-org-java3d-all.jar can be found on this page I do not recall which version was used, but for example this zip contain the jar. Would it maybe be possible to distribute this jar *inside* the reprap-host-0.X.zip package, since it only is a jar (and no .DLL/.SO files are needed) and is under a LGPL license?

Hi, I have started on the documentation for repstrapping "Richard". Basically, Richard is a clone of Darwin, but with the RP parts replaced by (hard) wood, aluminum and plywood. The advantage is, that you can gradually replace them with RP parts as you print them out. In the attached PDF file there is currently only documentation for the Corner Brackets and Y Bearing Housing, and the rest willby Joost - Reprappers
I think that I have the same problem as Eric. I can actually get the motors to run, but only a bit of friction and they stop. Also, running multiple motors (yay, I've got all the boards finally done now :-) does not improve on performance ... Joostby Joost - RepRap Host
Flashed a PIC today with the firmware Luis posted. At first I placed the PIC on my breadboard to do some more tests. For whatever reason, it heated up, smoke came out, and I figured this was *not* what was supposed to happen. Strangely enough, the PIC actually survived this torture and still worked. I then stuck in my stripboard, did some additional wiring and turned on the power ... the LED flby Joost - RepRap Host

Yes, and you need to add some additional through-vias, so basically solder a vertical connection using a small piece of (discarded) clipping form another component on both sides. That way you connect the two layers (Luis Freeman has got some nice images about this on his site) Joostby Joost - General
I talked to Simon McAuliffe a bit on IRC and explained my problem with the breadboard/electronics. He suggested some voltages to measure on the PIC, and it came down to the following: I've used the hex firmware files on Sourceforge (SF), but they seem to be for an older version of the Universal board (i.e not V1.1/1.2). The firmware version on SF uses different pins to send signals to the L298N (by Joost - RepRap Host

I have now spend more time with my universal stripboard/breadboard then I planned, and still with very limited results. So in order to be able to track down what goes wrong and where (PIC? firmware? board?), I was wondering if there is (existing) documentation describing what the PIC is supposed to do under given circumstances. For example, I noticed the voltage on pin 9 goes up when the Stepperby Joost - Controllers
I have - based on Jonathan's advice - flashed the PIC with the binaries on Sourceforge. Instead of PikDEV I used ic-prog and my JDM programmer (had to install Windows, but that was a minor issue). The PIC seems to be flashed and verification is successful. This should mean that the firmware now is OK and in the PIC. I tried to rebuild the universal board on a breadboard, and did some additionalby Joost - Controllers
Hey Jonathan, Thanks for this. I thought the binaries were in SVN, but couldn't find them. The ones on SF are different from mine, so I will try them. First attempts give some errors when flashing; hopefully I can solve that. Joostby Joost - Controllers
As a follow-up on this, I have been wondering if it could be the hex files that I use. I have attached the files that SDCC compiled (followed to the Wiki instructions), and hope that someone can either conform that they are correct, or maybe post the correct ones ... ? Joostby Joost - Controllers
Hi all, I have tried to test my universal board - as in connect it to the comms, attach a motor and see if it works, but it doesn't do much. What I know that works is the following. I have successfully flashed a PIC 16F628A with a hex file - did this multiple times, seems that it works correctly (although I am not sure of the hex file has compiled correctly). Things can be written to the PIC, veby Joost - Controllers
Hey Jonathan, That looks pretty interesting. I am currently trying to get my boards to work with the original software - and have some issues with that - but when that works, I will try the rxtx library as well using your patch. Keep up the good work! Joostby Joost - RepRap Host
Hi all, Today I embarked on the complete unknown - PIC programming. I was rather surprised to actually find out it was a successful venture ;-) The following is a short overview of the things that were done, configuration etc. Since I really am not sure *what* it is I'm doing, no guarantee it will work for someone else...

Hi all, I have been trying to grasp the Java code that has been developed so far by Adrian, Simon and others. While doing this, some things popped up and I wil try to put them here in order to see if these can be solved, handled or answered. Currently, Swing is used for the GUI. Would it be an idea to use the SWT library instead? This gives the app (1) a more native look-and-feel (on various pby Joost - Reprappers

Hey, When using windows, you might want to try to install only one Java version/SDK. Also install the additional packages needed (Java 3D), and then it should work. The mentioned copy command is for *nix flavours - in windows you could use drag 'n drop, but the installer should actually take care of most, I think.

Hi all, I have been experimenting on making the extruder parts, and since I do not have a lathe, I tried several things to make the drive screw And I found that when putting the screw in a drill (which has been fixated to my "workbench") and using a dremel like tool with either a cutting disk or grinding bit, this can actually also be done rather well.

Hey Bruce, The table bracket is made out of 19mm plywood and there are 2 types (as in the Darwin design).
