Z axis travel and asse

Mostly Printed CNC - MPCNC Troubleshooting
1

I got everything put together and was testing out movement. My Z axis would only go down a little and I saw that the tool mount for my router was hitting the bearings on the core. So I thought I just needed to remove the mount and lower the Z till the mount would be below the bearings but that only gives me about 5cm of travel on the Z axis. I don’t know if I’ve assembled it wrong or what the deal is.

Here you can see that if the top mount is installed, it will run into the bearings going any further down.

With it all the way up, but that only gives me about 5cm travel. And if I position the mount below the bearings, it will be the same, only about 5cm travel.

That doesn’t look like the correct tool mount for the Primo. Which router are you trying to mount?

The Kobalt one. It was the only Kobalt mount I could find on Thingverse.

Make sure you have the 2 plates that go behind the mount as well

Thanks, I’m sure that’ll do the trick.

Sorry to jump in on this post is there a mount for the kobalt on the Primo when ordering the kit? I don’t have a 3D printer and the options are for the makita, dewalt, 52mm and 55mm.

I would think so. That’s a Ryan question lol

@vicious1 do you offer a Kobalt mount in the printed parts kit for a Primo?

If you can’t get one, I have the files for it and could print one and ship it to you.

I’m willing to bet @vicious1 doesn’t even realize that its not an option in the shop. He is super busy so just try and be patient. He will see this and respond!

@Mahola419 are you sure you are looking at the right size printed parts? If you have a Kobalt I assume you are in the US and most of us use 3/4 EMT so that would be the 23.5mm parts

I was pretty sure that’s the one I was looking at. It’s 3/4 US Right? I completely missed the kobalt option. Thank again everyone. You guys have been extremely helpful to a newb

One thing that I have found is that it would have been easier had I known what cable management I was going to use before I assembled everything. Also, there are a lot of things out there for the MPCNC that are for the burly version and don’t properly fit the primo, so that’s something to be careful of.

18

What did you do for cable management? This is all brand new to me? I ordered the entire primo kit and printed parts and everything I thought I needed

19

Oh, that’s the part where I link to my Primo:

You can see the cables being bundled on the sides with the tape measure trick, in the middle with an aluminium extrusion and a drag chain (which could also be tape measure).

20

I downloaded the files to make this cable drag chain. It has different sizes for the X, Y, and Z axes. The chain itself is great but it’s one of the things that I made that was not made for the Primo and I had a hard time figuring out how to adapt mounts for it.
