--- Quote from: diogoc on October 16, 2014, 10:18:20 am ---I get the firmware for the Weller WD2 (with PIC18f6622), so if anyone need it ask me. With this and adding some components you can convert a WD1 into a WD2. --- End quote --- Hi, I have both a WD1 and a WD1M I would be very interested in converting 1 of them into a WD2(M). Preferably the M ;) They do seem to have different PIC chips though: the WD1 has a PIC18f6622 while the WD1M has a Pic18f4620 Is it the difference between the normal and the 'M' or just a newer revision? Also the 'power' boards are quite different. Could anyone please provide the binary file for the WD2(M)? --- Quote from: Smith on April 01, 2017, 05:17:52 pm ---The Microchip ICD can be soldered to the USB breakout PCB without any problems. Could you please tell us how to connect it? --- End quote --- |

The WMRP pencil does use a K-type thermocouple, and not a NTC like in all the other stations. I have a WD1M station, that I have taken apart to see how it works, similarly, i've taken an WD1 station apart to see, what the differences is. There is no thermocouple-amplifier in the WD1/2 station, so it cannot read a thermocouple iron (e.g. WMRP) So, it's not all up to software differences. // Per. --- End quote --- --- Quote ---Could anyone please provide the binary file for the WD2(M)? --- End quote --- It's also posted a few posts back. |

I kinda figured out that it's not possible by just looking at the boards, but I don't want to convert a regular one into an M. I want to convert a 1 into a 2. --- Quote ---It's also posted a few posts back. --- End quote --- As you pointed out yourself: --- Quote ---Thanks for the effort, but the fw file you've posted is just a bunch of zeros. Maybe the PIC was protected? --- End quote --- So thanks for the comments, but not really helpful... :-// |

You could duplicate the driver for the second channel, that doesn't look that bad. You'd still need the firmware, the handset connector and possibly a new transformer. If your goal is to not to swap handsets that often, you could keep the existing transformer, but it would still have a lower power output than a real WD2. I'm not sure if you can get an original connector. There's a possible workaround, though it requires some mechanical work (the notch in the Amphenol connector is at a different position) , check this for the part number. As for the firmware, the M version can be updated, there's a Weller program for that. Maybe the firmware can be extracted from it. |

I don't mind the limited power output, I would only be using 1 iron at a time. Getting the right firmware seems to be the biggest obstacle. I have the software for programming the WD1M, but it doesn't seem obvious to extract the firmware. I guess all in all it will be more trouble than it's worth, so I'm putting it on hold for now. Maybe I'll look into it again later... |
