Hey CNC forum
I have a large (1500x2000mm) belt driven CNC router inspired from Shapeoko 3.
It uses Megarail80 a linear aluminum profile similar to the ones on a shapeoko 3 in a combination with Openbuilds v-wheels.
This cnc build aimed to build a large format cnc on a budget. The cnc is now done and its performing okay. But now I would like to upgrade it a bit to make it able to do more “agressive” cuts. At the moment im able to cut plywood with a 6mm carbide cutter at 2200 mm/min with a DOC of 4mm. Although the cuts are fine it produces a lot of chatter!
As I see it the most weakest link in this build, is the long GT2 9mm belts (Correct me if im wrong)
So my main question is:
Would replacing the GT2 9mm wide belt with HTD5 15 or 20mm wide belt make an improvement?
This would be the cheapest fix due to an easy replacement of pulleys and belt and not to mention the price.
Or is there a different type of belt that would be better?
The other thing would be using a rack and pinion system but this would be far more expensive and I would have to also redesign and build my plates.
Best Regards
Morten
