NordicCNC's build log

For users of LiunuxCNC with the option to auto-square the gantry it is essential that the switches cannot overshoot their targets during deceleration and reset themselves before the whole sequence is finished. In this case you may need a larger target, especially with a large and heavy gantry.

I see, I didn't know that! Luckily I will be using Mach3! If I still need a bigger target for some reason then I can lathe a new target.

The devil is always in the detail.

Can I ask you a couple of questions regarding your CAD drawings that you're posting here...

1. Were they done using Fusion360?

2. Have you modeled all the elements yourself, like the carriages and rails etc, or have you just found existing DXF files and imported them?

3. If imports then could you share the source?

I'm asking because I'm using F360 and am having real problems with the dimensions of my imported DXFs. I've been using DXFs from the HiWin website, but whenever I import them into a design the dimensions are all out. The imported DXF are never the same dimensions as they are on the 2D drawings, so aren't really useful.

All I'm doing at the present is just using solid shapes to represent the items I want. So a HGH20CA carriage for example is a block 77.5 x 44 x 25.4 with a channel running through it to represent where the rail goes.

Looking at your design drawings, you seem to have everything fine?

Cheers

I don't use F360 but would imagine it works just like Solid works where it will allow you to import Step or Stl models which if Hi-win don't supply a direct F360 format like they do for SW you could use. DXF is mostly a 2D format and you want a 3D model.

Also for Component models I use Traceparts

Thanks for that tip. Looks like an interesting site.

I use Siemens NX which I am lucky enough to have a work related license for. If I wouldn't have that I would probably be using Fusion 360.

The linear rails and blocks are downloaded as STEP files from the hiwin configurator: https://motioncontrolsystems.hiwin.c...near-guideways

The ballscrews I have modeled myself without any threads. This is because I want to model the ballscrew F-lengths myself, and I have no need for the thread visualization anyway

I also use traceparts and grabcad for other models like servo motors. I like the STEP format best, no issues so far!
