Stepper motor speeds
Guys,
I have a pretty good handle on sizing stepper motors with respect
to required torque, but I haven't heard any discussions about speed
ranges and how they're controlled. I'm in the

Re: emc pinout
On TurboCNC you can change the pinouts easily - in the setup which is saved
in the ini file.
EMC and DANCAD don't have that feature, as near as I can tell. You would
have to get a 'breakout box'

Re: emc pinout
You can not change the pinout without modifying the source code and
recompiling. Not for the Linux beginner. The backlash works as well as
backlash can. No EMC does not read a tach (just wonder what

Re: Polar Coordinate based CNC
As it happens, my SHARNOA CNC Vmill uses Polar coords for
rapids (G10), linear feeds (G11), and circular
interpolation (G12 & G13). The Polar mode allows
geometrically pure ellipses, too. Also, makes

Frank,
I am the web guy and the code is not going to change as it is the way I

Re: Polar Coordinate based CNC
Since Y=rsin(theta) and X=rcos(theta) it is a very simple conversion. If
you want to go the other way it becomes: r=sqrt(x^2+y^2) and
theta=arctan(y/x).
Should be a simple conversion. The problem

Hi Lee,
Sounds like this would be similar to a Rho-Theta arm. Yes, the
controller would have to know how to convert rectangular to polar
coordinates. I'm wondering if EMC can already do this? That
