Re: [Emc-users] Modbus RS-485 Connection with Mesa?
Mark, Not sure if this helps or not. But for various control systems I use Moxa device servers for Ethernet to RS232/422/485. I talk to them over TCP/IP, but it can give you a simple telnet port to the device on the other end. http://www.moxa.com/Serial_Connectivity/Index.aspx Wesley - Original Message - From: Mark Johnsen m...@ijohnsen.com To: Enhanced Machine Controller emc-users@lists.sourceforge.net Sent: Wednesday, April 1, 2015 12:05:54 PM Subject: [Emc-users] Modbus RS-485 Connection with Mesa? I'm looking at controlling a X-Z gantry system w/ LinuxCNC (well really HAL and some code). Operator pushes a button and the gantry moves between two baths, waiting for pre-set seconds per bath. The positions are set and do not change. I was thinking of using a Mesa 5i25-7i76 combo and maybe a 7i32 1.5/3Amp or another off-the-shelf stepper driver. There's no-magic needed for this. I need some I/O for limits, home, inputs, outputs, etc. I realize the 7i76 is overkill for axis count, but I might want to expand to 4 axes later. I would take one of the GUI interfaces (touchy or axis, etc) and make my own suitable interface (easier said than done, possibly). The bath has a Love temp controller (16A2133-996) that can communicate Modbus RS-485. The 7i76 has RS-422 serial and the PC would have a RS-232 port. What's the best way to get to RS-485? I could use a RS-232 to RS-485 converter like this one from advantech: http://www.mouser.com/ProductDetail/Advantech/ADAM-4561-CE/?qs=%2fha2pyFaduhMyuR96x%252bdp4DnBDFhtESzKcpNyIUxvYPu1PngEfDtkA%3d%3d I thought maybe someone would have a suggestion? Might the mesa smart serial RS-422 be able to work someway? Regards, Mark PS. Considering my monitor turning off issues (previous posts), I'm second guessing using LinuxCNC/hal for this, but I'm a glutton for punishment..

Re: [Emc-users] Rigging Company?
Please note that I don't come from a machining background, but from a laboratory. Wrapping could be a good idea. We had a shipment travel cross-country that was covered and tarped. Looked like it went through the Mississippi River instead of over it...not fun to see on a device worth $700,000. A better question could be which rigging/shipping companies to avoid. my $0.02, Wesley - Original Message - From: Dave Cole linuxcncro...@gmail.com To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Wednesday, September 18, 2013 10:55:31 AM Subject: Re: [Emc-users] Rigging Company? 19,000 lbs is not a very heavy machine for most riggers. 30-40,000 lbs gets more interesting. :-) You should be able to find a rigger local to the machine to load it, a trucker to move it, and a rigger at the other end to unload and install/position it. Chances are they will all be different companies due to the distance. A reasonable price would be $750 to load, $750 to unload, and a few bucks per mile to move it if they can get another load on the trailer. That would include 2-3 people doing the loading and unloading. If they have to move the machine a distance on skates or via forklift.. that adds to the cost.Time costs money.. Step deck trailers are cheaper than double drops (with a well), they are more common, and can usually carry a second machine cutting transportation costs. The trucker should be responsible for tie downs on the trailer and tarping (if desired).Sometimes it is a good idea to be present to advise on tie down locations so they don't tweak the machine via the tie downs. You might want to shrink wrap the machine. Flapping tarps can tear up machines. I'm in Indiana and can give you some Indiana company names if you would like..

[Emc-users] general questions
I'm trying to answer a couple of general questions that don't seem like an easy find on the wiki, etc. Yes I know there are many contributing factors involved on accurate answers, so a rough ballpark is all I'm looking for. Without additional hardware: How many encoder counts per second can be handled? What is the PWM frequency range available? Same questions with additional hardware (Mesa, etc) and the estimated add-on cost? Help on any/all of these would be very helpful to me.

Re: [Emc-users] c/c++ interface
Wesley, For those basic functions, could you just use linuxcncrsh (emcrsh prior to version 2.5), see: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Linuxcncrsh Regards, Eric Thanks Eric. I actually just started looking into that as an option. In general, telnet is frowned upon for security reasons. But I have other systems that use it and we tuck them behind firewalls, etc. With this setup, the PC doesn't have to act as the server, only a remote device. I'm gonna follow-up and test this out.
