NordicCNC's build log

[AndyUK]

Yes, price difference seems to be only about 15-20% for either 25mm or 30mm rails. If it is bringing me added value and it isn't overkill, I think I am ready to go for the 30mm rails.

Don't forget to include the carriages in the cost estimate.

You'd be just about okay with a 1200mm 2010 screw @ 1500rpm.

Those of us using steppers rather than servos don't tend to go above 10m/min because the steppers will really lose torque above 1k rpm. My machine can just about handle 15m/min, but I'm leaving it at 10.

You'll have to find build logs for comparable routers using servos - I don't have any experience with them so won't advise.

I quickly compared the 1100mm HGR20 and HGR30 sets offered from BST Motion on Aliexpress (I have seen them recommended a lot here, Fred was the seller) and the prices came down to 210€ vs 265€, if I recall the numbers correctly. Both sets included 2 rails and 4 carriages. Seems like a very good deal to me. Even with VAT added is only like 260-320€.

Sounds good. I will have to see if I go for 2510 or 2010.

What diameter and pitch, ratio and stepper RPM are you running on your machine to achieve the 10m/min?

Good advice, thanks. I have looked around here and I will also browse through CNCZONE to see if I can find something similar.
