General Mach Discussion / Re: incresing speed on stepper motors

« on: January 23, 2011, 02:54:24 PM »

Ray -
I understand there is no shortcut. I have been focusing on the machine build and take advantage on what electronics I had first etc... I have a really nice build that I am happy with and now I am ready to try and upgrade to better electronics.

And YES I do need to plan it etc. but at the same time I am asking the questions so I can figure that part out now. I am ready to figure out what I need to get the performance I am looking for, but need help on helping me understand on how to do that.

Even though I have been experimenting with CNC for a while does not mean I understand everything or even much at all. I need help understand how to plan for what I want so I can effectively do that. I need to figure out what I need so I can figure out how much will it cost so I can save and eventually get those higher quality items.

Thanks!!!

And I do understand that I need to upgrade some components which is why I was asking. I can now start making a list of what I need compared to what I have and start budgeting for better quality parts.

If you don't really know what speed you want, tell us what your going to be cutting, and the people around here will know what speed will best suit your needs.

I do not understand enough to state what speed I really want. How ever the sign in the link I gave measures approx 10 x 20 inches and it took a few hours to cut. I would like to keep the accuracy and quality I have up till now and maybe improve as I go but also speed it up to where that job might of taken an hour or hour and half instead of 3 - 4 hours.

I am using the machine to cut various woods for guitar bodies or sign making.

here is what I cut out last night

On my current driver board posted above -
What is "Decay Mode Setting"? Not sure what this means or how it effects things.

Thanks

Ian -
What is single coil?

Let's assume I have the money to do all three at once (which I don't it will take a while) -
If I got the Gecko 540 (I want to add a rotary axis so figure this would be a good choice being 4 axis). power supply and new motors. What volt/amp power supply should I get with what motors? I want something that will be good and fast. Just have to budget for it.

When wiring motors -
When do you wire parallel or serial? I just rewired for parallel instead of serial on my Y axis and I can change the velocity and acceleration a bit faster and not have it stall.

Thanks

To change everything to 5 start instead of single start seems to be the most expensive upgrade. I think I am going to start small and work my way up. Gecko 540 & Power supply first and then 5 start and then the motors? Or maybe motors and then 5 start.

Current plan -
Rewire for parallel instead of serial??

Future plan to increase speed
Gecko 540 and what voltage/amp power supply using the motors I am using??

These are my beefiest motors. I don't have motors any bigger than these.

Thanks!!!

I am saving for a Gecko 540 and better power supply.
