Closed loop stepper motor kit power supply

[the great waldo]

Hi Jazz
I'm always glad to hear of someones own experience of an electronic piece of equipment. My cnc machine is going to be mainly used for carving wood, guitar making etc. Is the improvement in a closed loop system worth the upgrade? I've got the parts Leadshine MX3660 , steppers are https://www.upload.sorotec.de/doku/m...T6018L3008.pdf and an AXBB-e controller. If it's worth it in performance I would upgrade as I haven't put the machine together yet and the time saved as opposed to removing the motors and upgrading later would be worth doing it now rather than later.
Cheers

Hi Jazz
No need to reply on this. I've just checked out some of your previous posts, which lets me think that staying with what I have will be good enough for what I need.

Well youv'e got me thinking after your last reply. I can you the bits I have to upgrade an older machine and don't mind spending a few bob on something that runs better and I will be doing a fair amount of 2.5/3d cutting, and i'm getting old so anything that runs a bit better (quicker smoother ) i'm happy to invest in. Now the killer question is are the stepperonline kits ok (they seem to have great prices and there seems to be a 5% discount for us members) or should I look around a bit.

I've only used this brand on one machine and they worked fine. No better or worse than any of the others I've used and that includes Leadshine.
I did Kill one drive but that was my fault oversizing the PSU which is why I know they don't tolerate Overvoltage.!

Thanks good to know.

Many of the Stepperonline drivers have 'Leadshine' written on them as well and their part numbers generally match. One of the reasons I've used them in the past is that buying a 'Stepperonline' driver from Stepperonline seems like a good way to guarantee I'm not getting a counterfeit Leadshine driver.

Yes, there is a difference compared to a standard stepper, esp when doing 3D type work with lots of fast small movements as the closed-loop system ensures position with fast direction changes.

I've used about 12 sets now of closed-loop systems from different manufacturers and varying sizes from 2Nm nema23 to 12Nm nema 34 and all of them perform better than standard stepper system. Basicly just a little bit stronger, little smoother and in general feel more reliable.


However,Like wise I've built Dozens of machines using standard stepper systems without any problems. So if you have sized the motors/drives/voltage correctly for the size of your machine and left enough power for when running at higher feeds then you won't have issues.
Personaly because you already have the parts, provided they are sized correctly then I wouldn't have any qualms using them at all.

If you were buying from scratch then I'd Say get Closed-loop everytime because the difference is price isn't so great now and the extra cost is worth it.
