Welcome to the SeeMeCNC Community

Hello everyone! My name is Mike from Long Island, New York. I'm new here and just built my first 3d printer, the Rostock Max V2. I'm a Computer Science major and IT guy as well as a hobbyist with some experience in the Arduino area.

I gotta say, the Rostock Max V2 was a fun build and definitely the most involved project I've ever worked on. I've worked with plenty of printers before but never to this scale. It was nice having control over almost every aspect of the printer and made the printer a little more...personal so to speak.

Unfortunately, the printer is having problems but that sounds like something I should post in the troubleshooting part of the forums.

It's awesome to be part of a community as involved as this. I can't wait to get my first prints going and share them with you guys.

Thanks again and Happy Holidays,
-Mike

Hello Mike and welcome to the Forum!
It's great that you built your very own Rostock Max V2 and I thank you for purchasing the worlds best printer kit from SeeMeCNC.
You indicate that you have a problem and I hope that you did post the problem. That's one of the reasons we exist, to help other SeeMeCNC users.
Happy Printing and Happy Holidays to you!

Hello Eaglezsoar and thank you for the warm welcome!

I did post my problem in the troubleshooting section of the forums. Actually wondering if there's a guide on remapping the input for the Rambo board? Seems my HEAT 0 port doesn't work and I want to use the HEAT 1 input so I can at least print the fan shroud. I don't plan on using PLA for right now so I may be able to find another port for powering the fan after that print is done.

Thanks,
-Mike

Thank you, Eaglezsoar. The post did help a little. This confirmed my initial idea that I can change the pin layout and that my idea isn't crazy. It did leave me with more questions, though. I think I'm more looking for the proper way to configure the firmware to have the extruder just been seen as HEAT 1 and T0. It seems that my changing simple pin values does change the firmware a little bit, but it doesn't fully do the job. I feel as though I'm missing a big step, something as simple as "did you turn off the parking brake?".

Since no one (so far) is jumping on this to help you, I would ask your question also at the Delta printing forum at https://groups.google.com/forum/#!forum/deltabot
Someone here or the google forum should be able to help with what you want to do.

It's fixed! I re upploaded the firmware and tried HEAT 0 again just to see what would happen. IT WORKS!!!! lol
I will still post my question in the group though. I'm still curious as to how I would go about doing that. Could be a good way to save a board that may be considered broken but still usable.

You have to change pins.h, and remove any direct PIN number references to the pin you pick in configuration.h.
I haven't looked at recent Repetier versions, but fan pins were referenced as numbers in configuration.h in earlier versions, so by messing with pins.h alone you could end up with a single pin mapped to two functions, which didn't work correctly.
You can technically blow the output MOSFET, but I've never seen it done, it's far more likely you destroy e thermistor input, those pins on the arduino are VERY sensitive to any over voltage, and if the thermistor wiring shorts with the heater wiring, they go poof.

Cool thank you for the info, PolygonHell. I'm tempted to try this out on my machine but I think I'll wait a little and enjoy printing with it before I start messing with things.
