General Mach Discussion / Tool probe macro
« on: December 12, 2009, 08:44:57 PM »
I'm having problems with my tool probe macro. It's one that I had modified from one that I found posted on this forum. The probe is one with a spring loaded plate that is mounted permantly to the table of my mill.
Sometimes the tool will stop short of the plate and go home, so I usually jog closer to the probe. Sometimes it will feed AWAY from the probe. Pressing ESC will stop the feed and it will rapid home. It usually works fine, I get repeatability of .001" or so, but these actions really have me baffled. 

Thanks in advance

General Mach Discussion / ShuttlePro startup
« on: November 28, 2009, 12:41:52 PM »
Is it possible to set the "startup state" or default state of the ShuttlePro functions?
I'd like it to be locked and have z jog at startup



General Mach Discussion / lathe spindle speed
« on: August 27, 2008, 09:18:44 PM »
Just upgraded to V3.041 cuz I was having some issues with the lockdown.
Using a G95 to calculate feedrate from spindle speed. Have an index to get RPM, but spindle is not controlled by Mach, I turn on and off and set the RPM.
Problem is it sets feedrate to COMMANDED instead of ACTUAL spindle speed. If there is no commanded RPM it gives an error of no RPM in G95 mode and rapids thru cut. If I command a RPM, it sets the FR and won't change it if I vary speed. It worked in the lockdown, usually; sometimes it would rapid thru 2 cuts if I had rapided tool away after setup. That's what I'm trying to get away from.
Using the same XML file as the lockdown. What do I need to change so it will use the actual RPM to set feedrate?

Thanks in advance


General Mach Discussion / upgrade problems
« on: March 09, 2008, 03:37:21 PM »
I realized yesterday that I hadn't upgraded to the lasest release lockdown, so I downloaded it and applied it to my mill; this is where the fun starts. I had I believe V2.40 previously.
Even though I saved my XML file and reapplied it when I started having problems, I'm still having problems. Somehow an index value of 3000 was applied and the RPMs were way off. It took a couple of hours to find this and correct.
Now my problem is with the tool change. I don't have a tool changer so what I do is: Let the program call for a tool change, bring down the Z and touch off the tool and save tool offset. Then I move the Z up 2" or so, then single block as program moves x & y, starts spindle then moves Z down while applying the offset. It's worked for me for a couple of years. Now, I touch off and save offset, then it goes back to the X&Y where I moved it from and the Z goes to where I set the offset. What has changed?
Enclosed is the screen dump of the config page and my XML file

General Mach Discussion / Mach Lathe questions/problems
« on: June 15, 2007, 10:26:45 PM »
Hi guys & girls,
Me again. I'm having problems using lathe. I've worked most of the problems out myself, changing my post, but 3 things I still can't figure out. I'm hoping a lathe guru can help me out. I've learned a lot lately about what to do and not do and I'd like to do a FAQ or other posting where all I've learned is in one place. I've seen that lathe is not near as popular as mill and documentation is spotty
So on to the questions:
1st: when I send the axes home, they do not "zero out". I have set everything I can find to make them do that. I set x & z zero at home and no tool (T0) active when starting Mach
2nd: The offsets do not repeat after homing the axes, so if I have a G28.1 at the end of the program, I will need to touch off again; the amount they are off is different than the # on the screen when homed before I set it to zero.
3rd: Is there a way to just send the axes home without "any other" move taking place? G28.1 X0 takes x to X0 at rapid then home at a slower pace, G28 X0 goes to program X zero. On a Fanuc G91 G28 x0 goes straight to X0. , here it didn't do that, but I don't remember exactly what it did. My brain is frazzled.

I'm using the latest version of Mach3
Any help is appreciated


General Mach Discussion / Lathe offsets
« on: June 11, 2007, 08:38:51 PM »
Is it possible to have the offsets work as a diameter instead of a radius?
I can't find anything except lathe as a whole as rad or dia, and this setting doesn't affect the offset register


General Mach Discussion / Screen 4 for lathe
« on: June 10, 2007, 07:56:56 PM »
Does the command"set next line" not work in lathe (V2.0.040)?
I added a button to my screen and when I press it I get the diologue and menu for"run from here"

Thanks in advance

General Mach Discussion / ShuttlePro problems?
« on: April 12, 2007, 08:44:13 PM »
I'm having problems accessing the tooltable and some of the config screens in Mach3 (V2.04) I reformatted the computer, and still the same; click on the tooltable button and it DOES come up but takes about two minutes to do so. I then started setting up a new config file to narrow it down because it works on my lathe computer, which was the previous mill computer. Everything works as it should until I install the shuttlepro plugin and configure it. I'm using the shuttlepro express. The computer it doesn't work on has XP SP2 and is 1.3 Ghz. It works on an XP SP1 800 Mhz computer.
I'm at my wits end here, I even tried the latest Mach version and still the same result, wait awhile and the tooltable  or other windows come up.
Does anyone have any ideas?

General Mach Discussion / shuttle pro not working
« on: January 25, 2007, 10:29:28 PM »
I got a Shuttle Pro and can't get Mach to recognise it. The Shuttle Pro software is not installed. Nothing works. I checked the "Reset device Selection" and rebooted. I got a "no shuttle detected of type selected" error upon next startup. This on two computers. I selected all choices in the plugin config screen. I then installed the Shuttle Pro software and everything works as it should. What should be my next step? I'm really dying to get this to work; makes my cnc conversion just like the "big guys" at work.


Mach Screens / newbie question
« on: December 28, 2006, 09:56:45 PM »
I'm trying to learn Screen 4 and I have a question that I'm sure has a simple explanation. I want to put a "set tool offset" button on the main (program) page just like on the offset page (page 7). This is in the standard 1024 .set as supplied with Mach3.
I changed the settings for "Jog on off" to those of the button that I want, but get an error "error in line 1 - none". Then I copied the button from the offset page, but can't resize it to fit where the previous button was.
What can I do? There seem to be some differences in the button/image button settings, but I'm getting lost here
Thank you in advance
