Re: Craftgizmos Rostok MAX

You obtain the remainder of the wires from the other connectors on the power supply - typically the four pin molex plugs will have one red, one yellow and two black. As to where they go, it's pretty clear. You place the "triple" bundles on the far right terminals as shown in the photo in t...

Re: Rostock MAX Assembly Manual

Glad to hear it Tony! You need to post pics of your test cube. :)

I updated the manual again today with a clarification on the heated bed wiring. Yesterday got an update as well. :)

Re: Phebe I Power Wiring

I strongly suspect their choice of fuse was more due to real estate savings than worrying about the optimal part choice.

They could have deleted the fuses entirely and made it a very visible requirement that the end-user fuse all the power output lines.

Yeah, the clarification to step 22.4 got lost when Word decided to go smell the flowers and contemplate its navel. The bit didn't get added back in after I restarted Word. New version is up that should clear it up. If not, yell and I'll tweak 'er again! Yeah, you need to be careful with the sanding ...

Re: Phebe I Power Wiring

With regard to those annoyingly tiny fuses - I blew the one right under the 20A resettable and ended up soldering 24ga wires to the "top" so I could use it to attach a tiny automotive fuse of the same rating. Looks like hell but it works very well. :)

Re: Rostock Max Door orientation with LCD?

fredini, if it was me, I'd install the LCD door where the solid face door went. When I get the LCD for mine, I may design a partial enclosure for it that is open to the back and just attach it to the electronics door using a few neodymium magnets.

Re: Split Flex Tubing - Rostock MAX - and a few other questi

You don't want to use heat-shrink tubing on the hot end anywhere unless it's rated for at least 260C. The wiring was damaged because the knurled nut at the top came loose over a number of heating & cooling cycles. I've added a note in the manual to take special care to monitor that nut. You migh...

Re: Rostock Max Limit switch wiring issue

The end-stop wire for the X axis should enter the electronics bay through the same slot as the power supply wiring does. If it's too short, how does it compare in length to the other "Short" cable?

Hehe. I'm glad you like it! Those connectors are called Molex. "Molex" is a commercial brand that covers a wide range of connector sizes and styles, but they're typically the larger white nylon connectors commonly found in applications that consume a lot of power (appliances, etc). I doubt...

Re: connecting the heated bed

fredini, you're soldering the thermistor wires to the back of the board after you pass them through from the top side. The RTV (or Kapton if you have some) does two things - it affixes the thermistor tip to the board and it prevents the thermistor leads from shorting together from being bumped into,...

Six feet is more than enough. I use 3/8" as that's what I had handy. There's plenty of room in there for the wiring. It sounds like you've got the bracket mounted properly. If you are still concerned about it, post a picture and I'll take a look. You can use RTV to insulate the leads. However, ...

Re: Split Flex Tubing - Rostock MAX - and a few other questi

Craftgizmos, the length of split tubing depends on how your route your wiring from the hot end. What I did was tape one end of the tubing to the hot end and then walked it along the wire path until I reached the point where the wires would enter the base. That's the point I cut it. You may have a bi...
