Welcome to the SeeMeCNC Community

After lurking for weeks, comparing the Rostock Max to every cartesion & delta 3d printer out there in the US, I decided to pull the trigger and join all of you with a Rostock Max build. Thanks to all of you on for this fantastic user forum. It has given me the confidence that I can build the kit and overcome any problem that may arise. Your time, posts, images & links are greatly appreciated.

I have also purchased (based on your advice):
- Noctua 40X10 replacement for the Rambo fan
- Coolerguys Dual 80mm Cooling Fans ( the Max will reside in an upstairs bedroom - my office- that has no air conditioning in the summer)
- Rostock damper kit
- the permatex ultra copper & kapton tape spec'd out in the manual

My question is what have you guys done for the uninsulated cable crimps (would be nice to have a quick change option), & connectors? Have you followed the manual verbatim with all the hansen stuff, or are there any alternate suggestions?

Thanks in advance.

I assume you are looking at the Heating Resistor installation. I actual went with a single 40W heater cartridge from the get go. To connect it to the wiring harness I used an XT60 (BT60) connector set. It is secure, insulated and easy to disconnect. Gene has a VERY good video on YouTube showing this modification.

If you go this way, you might also consider using the Screw In Thermistor in addition.

Works well for me but your mileage may vary.

Good Luck!

I went with Hansen like the manual suggested. I do have to give them a shout because they noticed I missed something on my order. I bought everything I thought I needed but they emailed me later asking if I'd meant to order some female terminals to go with my housings - yes I meant to! So I was very glad they caught it. I'd happily do business with them again.

Now that is a great suggestion. Found these on amazon.Thanks very much. Still trying to find the video you mention though...

Probably this one? https://www.youtube.com/watch?v=xvXKt3xDt4E

Thanks for the link!

Also should have mention I am trying to get away from crimping (and having to purchase a crimping tool). What do you think of these? https://www.adafruit.com/products/1664

4-pin type here https://www.adafruit.com/products/578

Why is everybody afraid of crimping? It is a) easier than soldering b) cleaner than soldering c) quicker and d) better than soldering and e) a crimp tool costs less than a soldering iron.

What gives?

Those of us who are senior citizens have a problem seeing the small contacts, shake too much, etc.
Others are just inexperienced and ruin a lot of contacts, that's why they do not like crimping.

Ah I see. A ratcheting crimp tool resolves a lot of those issues. Holds the pin in place for you, you just have to jam it in with some certainty and squeeze!

I have the ratcheting type of crimping tool and I have mounted a 4" magnifier so that I can look through it to be able to see that the pin is properly inserted.
Sounds dumb but as your eyesight has a hard time focusing on something small this setup is the cat's meow.

There are several reasons I prefer to stay away from crimps.
1) $34.95 for the Pololu crimp tool is a bit steep when I already have mad soldering skills and the tools to support them.
2) Having worked on military battery packs, I understand and have lived with what works in a shock, vibe, constant use situation and so have my preferences.
3) I might qualify as a senior citizen.

I'll just throw my 2 cents in here too...

I bought a ratcheting crimp tool off amazon. I thought they were all the same. Well, mine didn't have notches in the teeth for crimping down the tiny little connector pin thingys. It was designed only for butte connectors / o-rings / other big things. So that was a waste of money, and it's hard for me to justify buying a second one.

Moral of the story: make sure if you're buying a crimp tool, there are notches in the teeth.
