Welcome to the SeeMeCNC Community

I have been using TC for several years. Started with V8 and now on V19.
It's okay. Kinda like Autocad, so not the easiest to learn.

That said, I find that when designing parts to be printed, less is more. Clipped corners instead of radii and no rounding of edges provides a much smaller file size and thus prints faster.
I posted this on my log at the CNC Zone, so this is basically a repeat.


The image in the first picture has an STL file size of 345 KB.
Second is about 2500 KB. Nearly identical parts. Little variation, but nothing major. Big difference in part processing and printing. Second one would have taken over 7 hours. I haven't yet printed the first one. Still tweaking it.

New X carriage with belt clamps? Very nice!

Keep us posted on this. What type of bearings are you planning on using?

Those were taken from Thingyverse and then I modified the design some.
I like to use threaded inserts for plastic rather than just nuts. The nuts often want to fall out, but inserts stay put. A little easier to print just holes rather than nut reliefs as well.
Cost a little more, but ease of use is cool.
These are for LM8UU bearings I think.
Mine are the SAE 5/16" type.
They work great.

Nice!

What extruder is this for?

Ah. I m not sure what all will fit this, but I know both a Wade's style and a Greg's open style will work. Both common ones with Mendels.
