Hi,
With PPR i mean Pulse Per Revolution, I set mm as main unit, I'm still tring with stepper and I set it to 8 microstep without gear reduction

4500mm/min in my case is 900rpm so 15 rates per scond, so 15 rates per second at 1600 pulse per rate = 24khz per axle and so 48khz for 2 axis....

then i can't run mach at 25khz.

Anyway it's not a driver problem because it happen also with only 1 drived hooked

it is a new set up, because I want to change the steppers with servos so I need to set an higher value of ppr

It's working fine from 2 years and 1.200 hours of 3d works, but usually it is sets to 400 ppr, rapid speed at 315 IPM and working speed at 200 IPM.

I think it is not a hardware problem because, as i told, if I connect only 1 driver to the pc and I manually move 2 axis, the only one that is moving and connected, immediately slow down

I have some problem with high number of pulse
Setting my stepper driver to 1600 ppr and setting mach to 60khz, at 4300 mm/min (about 169 ipm) per axle.
When I manual move 1 axis it's ok, but when move 2 axis  together they showily slow down or lose steps, 3 axis together... Disaster!!
I tried to use 2 axis but only 1 driver connected, well the only one connected slow down anyway

My pc is a pentium 4 3Ghz with 1 Gb of ram.
I installed mach on a clean version of windows as artsoft recommend.

I tried to install the latest version 2.01 and set the kernel from 45 to 100khz but nothing change.

Why it happen

Thanks

Anyone has tryed this brushless servo + driver?

http://www.omron-ap.com/product_info/SMARTSTEP/index.asp

Thay say that it is simple to makes work as a stepper motor.
What do you think about it pretty cheap too.

Anyway, I'm looking for a servo system that doesn't need adjustment, there's something like that on the web?

Thanks for all

General Mach Discussion / Turn off toopath diplay

« on: March 09, 2007, 04:28:54 AM »

Hi there,

How can I turn off the toolpath diplay?
I need to do it because I have to load a huge file, when load it, it makes mach go slow... I read something about this in an old post, but i can't find it.

Thanks for all

I have to try some changes and then I let you know if it works...

I have no time at all... so I never work on it.
