In other words, it's fine as is?  Thanks.

ps. I see the wiki now, but it doesn't appear to be for people getting started.

General Mach Discussion / NOOB Question concerning the red boundary line in the display area

« on: October 17, 2010, 07:32:48 AM »

Hello everyone,
I've built a 2'x4' kit with dual X R&P drives and lead screw Y and Z, and have it put together, and have been working at getting Mach3 up and running.  I mostly have been following the pdf instructions, but have recently found the training videos.  In all of the training videos, the table's boundaries are represented by a red line.  I have both limit switches (I have just one set of switches on my X, as opposed to having both X and A wired) and soft limits configured so that they seem to be working properly, but instead of a red boundary line, I see a gray 3D box (it's only 3D when you rotate the display off axis, otherwise it's a 2D box!) made up of dashed gray lines.  I can't help but feel I have the limits screwed up somehow.

Any advice? I'm completely new to this, so there may be some basic concepts I'm missing that would be obvious to someone with more experience.
Thanks!

ps. this site needs a wiki

General Mach Discussion / Re: Hot stepper motor

« on: September 26, 2010, 10:05:56 PM »

I'm also new to this, and I fired mine up last week for the first time, and thought my steppers were hot, also, and contacted two well respected individuals on the subject, and they both said it's normal.  Yes, you need the right resistor, and the one guy, Ahren from CNCrouterparts.com--he's the guy who sold me the steppers--said he could send me different resistors that would resist more, and keep the motors cooler, if I'd like them to be, but that it would be fine if I just didn't worry about it.
