Modified TopsCNC from Germany 🇬🇧

26 oct. 2020 09:18

Hallo

Ich habe eine Version TopsCNC Heavy 23 mit einem linearen Glet-Lager hergestellt. Bessere Steifigkeit, höhere Genauigkeit. Ich benutze eine 1,5 kW Vierkantspindel mit Luftkühlung. Daher ist die Frontplatte etwas anders. Außerdem habe ich eine SFU 1204 Kugelumlaufspindeleinstellung vorgenommen und Nema 23 für die Z-Achse installiert.

Alles auf Thingivese zu finden.

ok, surely in english.

Have you also provided a dust extractor?

It was on the lower part of the old Z-axis.

Thanks for the data.

I also thought about it for a long time with the vacuum cleaner and I found this.

This is what the suction looks like. It's not mine and is really only suitable for wood. I think that's enough in most cases.

Merhaba Kamil Bey beni de fusion 360 grubuna ekleyebilir misiniz? teşekkür erderim.  uzeyirilden@gmail.com

Hi Kamil thanks for your job.

Could you add me please : socorro@free.fr

Thanks

Hi Kamil,

This thread was fascinating to read! I'm curious to see your Fusion 360 project file as I do use that software. I'm definitely considering moving to ball screw on my X axis at the very least to mitigate backlash and deflection on the gantry. 

Would you mind adding me? localizethis @ hotmail.com

Thanks!

You are invited. Please check your mailboxes.

@JR what's bending for you? Have read about it on the forum, but I do not know exactly what really bends there in the X axis?

Hi Kamil,

Thanks for the invite!

On X+ and X- movement, there can be excess vibration and deflection at certain cutting speeds. This tends to happen more on contouring and I end up with jagged edges along the sides of my part. Nothing major, but I'm a bit of a perfectionist. My machine is on 1000mm X 1000mm profiles, which doesn't help either given the length of the 8mm trapezoidal screw which tends to be prone to some wobble and backlash.

The ball screw will help stiffen and stabilize the gantry, but I also have a stretch goal of switching to linear rails on my X axis as well, given that plastic wheels inherently have play in them.

These vibrations, is it only with aluminum or also with wood?

26 mars 2021 20:12

No problems whatsoever with wood. Mostly Acrylic and Aluminum (6061). Don't get me wrong - I still get very good and precise results, but I'm always looking to improve my machine. I've got another post showing some of the stuff I've been able to accomplish so I'm not complaining that much. 😊
