Still unsure if my current motors are good enough. I have the 286's currently mounted but I also own from a previous build the 276's.
Have you looked at and understood the torque curves I posted yet? BTW- Hint - there's info missing - what don't they tell you?

I am not 100% sure what those charts mean.

Then I'd have to say your nowhere near deciding on a PS or drivers or anything else yet.

I'm not trying to be difficult here - believe it or not I'm trying to save you wasted money and another disappointing system. Why not read the whole thread again - there's a lot of good stuff in it about where you should start.

I understand speed of the motors are controlled by velocity and acceleration. How do I make my motors go faster without them stalling on me? I see other machines cut really fast and mine seems slow in comparison when I see machines in videos.

If you don't have resonance dampeners installed you might want to look here and here.

I made and installed them for each axis and the difference is night and day.

I read through that first link - a lot of great info. Will have to try the other later, can't pull up cnczome.com at the moment.



THANKS!!!

Thanks for all the help folks....

I have learned a lot and now realize I have a lot more to learn. Before posting this I did order a 37v 10 power supply and that did arrive today. So that will be nice.

Everytime I learn something I always find there is something else I still need to learn.

Thanks
