Thanks Chris for your help with the mdi problem that seems to have done the trick. I'm not sure what happened to cause that- I will have to check the ini file for starting G codes.
Always helps to have someone else lokk at a problem with 'clear eyes'!

Hi All -
This sounds great, I recently purchased a 5i20 and a
7i30 from Mesa and I am currently doing some testing
to get the whole setup working. I can help out with
the testing effort if necessary.
Also, as I understand it should be fairly easy to get
the 5i20 to work as a Stepper driver using

They are essentially voltage mode. Output voltage = DC power supply

Several EMC developers are planning on getting m5i20 boards in the near
future

Hi,
I transfer my files (.ini, ngc, txt, etc...) from windows to linux and from
linux to windows using a USB pen regularly without problems. On windows I
edit them using Notepad++, a useful editor suitable for most of the existing
programming languages.
If windows doesn't read your USB pen mayb

I find that Ubuntu is very happy to access shared folders in a Windows
workgroup so that gives convenient access over a wired network. It should work
on wireless if you can get a wireless adaptor driver going. I tried in the
summer but gave up not having enough Linux expertise.

I'm trying to educate myself on EMC2 while working on retrofitting a lathe and
a future controls upgrade on a mill. The single biggest hinderance seems to be
that all the computers I use, except the EMC2 computer, are windows based. I
plugged my flash drive in my Linux PC and transferred linux
Hi Chris,
this sounds to me like you are in relative mode, not in absolute mode.
Check if you have G91 active instead of the usual G90.
Maybe it's in the ini file as a RS274NGC_STARTUP_CODE.
Regards,
Alex

Peter, would changing to a max 66 kHz PWM frequency on the 5I20 simply
require a new fpga configuration to be compiled and downloaded to the
5I20, or does it require a hardware change ?
