Welcome to the SeeMeCNC Community

Thx Eric I didn't see that diagram before but I was sure I had clicked on all the links. :oops: I am trying to put a diamond head with magnetic ball mount onto a V2 with the HE280 level sense. So I have a Rumba board not a Rambo because of the need for 3 extruders. Thats mainly why all the colors an...

There are full V1/V2 upgrade instruction here: http://seemecnc.dozuki.com/Guide/Rostock+Max+v1-v2+HE280+Hotend+Upgrade/49#s402 No wiring diagram but there is a detailed description of what wires to splice to the new whip as well as how to re-wire connections on the RAMBO board. There's also this di...

I believe that in general, an M3 grub screw is sufficient. Assuming a class 12.9 grub screw (The ones I source are 14.9, so stronger yet), the proof yield is 970 Mpa, or 828 pounds of force (Assuming an area of 3.8, which is below what the specifications allow for minor diameter). The minimum yield...

I did discover that I could loosen the M3 screw in the Titan by using a 1/16" Allen wrench. Go figure.

g.

Since the M3 screw didn't get tight, "perfectly adequate" sounds pretty silly to say.

I still have no confidence in this M3 grub screw that came with the EZR extruder. It just not tight. I finally decided to use the M4 drill bit and tap and use new grub screw. I was surprised the metal it not hard at all. The drill bit sliced thorough the existing hole with little resistance. I didn'...

Any further progress on this Probe?
What pins are used to connect to the controller for this?

Looks like the best option is removing the M3 grub screw and drilling a new hole and replacing with a stainless steel M4 grub screw that will not strip "so easy".

@Gene, So of your 30+ EZR struders, none of your allen wrenches that came them spin when you try to tighten the grub screw? I have 5 and they all did. Something strange. They act like they are english and the screw is metric or vis verse. Did you use the allen wrench that came with the kits or use y...

I disagree. Its too small for this purpose. The provided allen wrench can't tighten the grub screw without stripping. I tried it on more than one. Same result. The lock tight would be potentially useful if the screw got tight. As I said if it was like the pulleys it would be OK. Maybe you use a diff...

I got some EZR Struders to replace the old EZ ones but the tiny allen wrench included does not tighten well and comes loose quickly. I put lock tight on the belt drive pulleys but the HOBB drive does not lend itself to this. (to small) Seems strange to have a 12mm diameter hobbed drive with a tiny M...

Geneb, Step 22 says "Insert some wisdom here" ;) Without receiving my V3 and no pictures of a working machine it seemed like a good question. What is the height of the spool center from the desktop? How long is the bowden tube on this unit? The V2 had a very short bowden tube since it was ...

What temperature does that thermal fuse "pop"? The web site and manual says nothing I could find. That new hot end is a major good move. I hate RTV and it takes forever to assemble. The new hot end looks like a drone with 3 motors. Anybody independent reviewed the autoleveling feature yet?...

Moved to Rostock Max V3,

Interesting feedback. Thx, I think. That's the problem with 3D printers, it's hard to find any information about what to do. There is plenty of advice what not to do. Tons of Chinese crap out there with labels of E3D on it. Amazon makes it easy to get stuff but not good feedback on what does not wor...

I installed the ezgroove mount from SEEMECNC for the ROSTOCK MAX V2 because I wanted to use some higher temperature material. Poly-carbonate. SEEMECNC does not support the ezgroove even though they sell the mount, so I need help making it work. I attached a j-head hot end I bought on Amazon. I used ...

Does anybody have a working link to these 2 parts?

Did you ever get your Diamond extruder to work well?
