Fer mayrl,

Send me an email, I contacted them and you seem to have better pricing than I can get locally

if you get me your price data and source maybe I can beat them up some

Hey,

Those guys aren't too far from me!  If you think its tough trying to source components in the states imagine how difficult it is when you don't speak the language!

I'll have someone contact them to see if I can get my hands on a few to try out and report back...It'll be a couple of weeks though.

Thanks for the tip

Newfangled Solutions Mach3 Wizards / Tool List and NFS Conversational

« on: January 20, 2006, 02:42:15 AM »

Brian,

Is there a way to link the tool table in Mach3 to the NFS wizards?  I still think you need to be able to override in the wizards, but it would be nice if the default went by tool #

As I am thinking about it, rather than just Triangular pocketing, could you do polygonal pocketing, where the user can specify the several points (in order) and cut multisided or irregular shapes?

Newfangled Solutions Mach3 Wizards / NFS Addins for Mach3Mill Questions

« on: January 16, 2006, 01:14:58 AM »

I had a couple of questions on the Addins:


I am currently on Mach3 release version R1.83.038

On "Cut Rectangle" 1/8' dia mill, cut outside, 2.00 length and 1.625 width, part came out 1.75 x 1.375, I tried it a couple of times, let me know if you want the posted code.

also on "Cut Rectangle", is there any way to suppress the leadins?

Would it be difficult to add a Triangular pocketing wizard in conversational?  Maybe specify the 3 vertices and choose inside or outside?

And finally, as you improve the addins, what is the process for updating? is it to download the newer version of Mach3?  The current version is 1.83.046 are there already changes in the newer release?

Thanks, the support you guys give your products is spectacular to say the least

General Mach Discussion / Re: Limit/Index Wiring

Brian,

Thanks, that worked, the schematic now looks like this:

To LPT Pin
        l
        l               NPN
        l------------\_/----------Gnd

Am I correct in assuming that now the transistor is now simply sinking the current  from the port, whereas before it was trying to sink the port and the power coming through the resistor?

BTW here is the link to the sensor:  http://catalog.sensing.honeywell.com/datasheet.asp?FAM=infrared&PN=HOA1887%2D012

Thanks for your help

General Mach Discussion / Limit/Index Wiring

« on: January 08, 2006, 07:24:29 AM »

I am attempting to wire up limit and spindle index sensors using some small honeywell opticals.  I have a 10K pull up in the circuit. My issue is that it does not seem that the circuit will draw the port pins low consistently.  It will draw the port down to ~1.4V when bread boarded and 1.8V when soldered to a piece of PCB.

When first connected it work fine, when I block the sensor, it drive the output high (~4.5v) when I unblock the sensor, the voltage does not go low enough to reset the LED on the Mach 3 Diagnostics screen.

Basic schematic

                            to LPT Pin
                                l
              10K             l               NPN
+5v-----^^^^^-------l------------\_/-------- Gnd



I have tried using larger pullups , up to 1M, it doesn't seem to make a significant difference.

Any thoughts?
Randy

I have some Honeywell HOA1887-12 photo sensors I would like to use as limits, homes etc. 

Link to datasheet: http://catalog.sensing.honeywell.com/datasheet.asp?FAM=infrared&PN=HOA1887%2D012
Link to Schematic: http://catalog.sensing.honeywell.com/Author/Images/honeywell/ir/sch_027.gif   

It is the non-Darlington Schematic

Does the collector or the emitter go to the signal pin? do I need a resistor of any sort?

Thanks
