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

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'

Before I lost a hard drive, I had a dxf or vector or ?? drawing of a heron in a circular cutout, with bullrushes etc. in the water where the heron is standing on one leg (how else do they

I know you said "off list", but I think a lot of folks would be interested in the general price range for systems like this. Can you give us an approximate idea of what something like this would

Hi: Just a note that Mach1 Alpha 11.0 is online. It includes subroutines of the fanuk variety and Macro capability along with Visual Basic scriptlets which can be exectuted with M-Codes of your

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

can you change the pinout the board i use has diffrent pinouts (step and direction for x y z axis)also does the backlash comp work good and also does it read a tach i use turbocnc now but as a

That was one of the prime reasons for me to get a subscription. I was interested in the "Heavy Metal" milling machine project. I even bought a few back copies to get all the articles, a few months

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 want to do it for my reasons. If you don't like it don't go there. You are more than welcome to use any style of code

This it a common thing,.. The programmer is using a redirect which keep sending you back to the same page. It is BS !! I am using Netscape. With Netscape just place your mouse pointer on the "back"

As I said, Im new to all of this. So using Surfcam is a bit confusing considering they give you very vague documentation of all processes. But Im learning. And what I cant figure out.........Ive

Hi, I build custom drive units in both servo and stepper models. Voltages from 24 to 80 and currents up to 40A. I can supply a system with or without motors. Motors can be new or surplus. Here are

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

Al, Not sure if I am following the problem completely. Tell me if this is the situation. You go to the FAQ page at: http://www.ktmarketing.com/faq.html And the FAQ site loads properly. You then try

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

Tim, When I click on your link, it works fine, BUT it won't let me back out. Have to go to my favorites menu and start over. Is this something easy to fix? Thanks, al you access instead you
