I added a post to this thread (third page) asking for recommendations for steppers, but I thought that subject might warrant its own thread for others to read too.
So disregarding my specific machine, what stepper motors work well with Mach3 and a Gecko driver. I think those of you with experience in this sort of thing (John, Evan, Weston, etc.) would have good advice to offer. OF course there are other good drivers and softwares out there and the same motors ought to work as well with any of them, I just mention Gecko and Mach3 because they are very common/popular and it's what I have too. I figured maybe some recommendations could be made for a range of machines from small like mine to larger ones so others could read this and apply the advice to their own project.
So I guess the question is, for CNC motion control, are there recommended stepper motors to use in terms of brand, specs. etc.? Are they all really about the same and should work if you have the right stuff driving them? Seems like the ones I see on eBay are about the same as the ones Kelling sells but I don't know - maybe they are different and it's just hard to tell. They appear to be generic "no-name" steppers but have similar specs to the name brands for less money, etc.
The reason I ask is my little CNC machine has pretty awful performance from the little steppers I'm using. Maybe they are just too small? They are Nema23 and a little less then 40mm long. They have the standard 200SPR and are 4-wire bipolar motors. With Mach3 and Gecko drive, they have very rough and noisy motion at slow speeds which doesn't seem like it ought to do at all. My Y-axis was working OK at first when tuning motors via Mach3, but after setting a few things differently, that axis got to where it doesn't even turn, though it makes the noises as if it's receiving the driven signal from Mach3. Just not turning. And I can't make it go at all now for some reason. Just thinking maybe I need to upgrade my motors a notch or two and want to get something decent this time so I can get past it and move on. Seems like every move I've made so far has netted zero or backwards progress and I'm getting frustrated.
Well thanks for any help.
