General Mach Discussion / Re: A couple of questions re servo's

well my thinking is that rpm and volta\ge are linked and ive checked this ie at 2800 rpm on a gecko the motor is drawing 24 volt

General Mach Discussion / A couple of questions re servo's
« on: December 28, 2011, 11:06:02 AM »
Hi and Merry Christmas/happy new year!
firstly I'm doing a bf20 conversion using gecko 320x drives. my x an y are 24 volt and my z is 36 volt.
I have a 36v powersupply and I'm thinking as long as i don't try and run the 24volt servos past there rated rpm at 24 volt I should be OK powering them from the 36 volt power supply?
  Also fat32 or ntfs whats the best for mach? I know audio recording software works better with fat32 because it writes in realtime rather than blocks ala NTFS,would this be an advantage ?
Finally (for now) how have you guys got around the limeted space on the y axis when fitting ballscrews?
   regards

forgot to mention its an ecopy touchscreen monitor and i think you can only run the screen with the appropriate pci/agp card,apparantly.Wether it can be hacked or not i dont know. it would be absolutly perfect for the application if it could.

General Mach Discussion / sharp 10.4 screen
« on: November 21, 2011, 09:04:45 AM »
Hi I have just aquired a sharp LQ104s1dg21   10.4" colour  screen.
I would like to use it in my mill enclosure.the problem is im not sure on how to wire it up,there are plenty of pdf's with the pin outs on one of which i have attached, and i am assuming its vga or svga?
could some one please have a look into this and point me in the right direction?
  Thanks in advance

so any drawbacks or contenders to the smooth stepper? is the backlash comp a software or hardware upgrade?

Cheers,
   the reason I asked is because the smooth stepper seems a bit short of pins ie if you want to run an encoder wheel?
plus I believe there is no backlash compensation?

General Mach Discussion / multiple handwhees
« on: February 14, 2010, 10:31:29 AM »
Hi,
  I have built a pendant for my mill with an encoder. it all works fine.
Is it possible to put two encoder's/handwheels on so that it is more natural to use manually?

Hi,
 I need to operate some relays to opreate work clamps etc.
I know I can use spare coolant g code, but how do you do it without
using g04 Is there spare g or m numbers that can be used?
