General Mach Discussion / Re: Restart issue + jogging question
« on: March 02, 2007, 08:28:28 AM »
Well, that explains a lot. Now I see what the table is for in the config. setup menu. I was wondering what that was used for but never asked. Truth be told, I've been using a screen that I designed for myself. I've tried to make the screen so that I didn't have to use the mouse (at least keep it to a minimum), just keystrokes where possible. Now, I've added the Jog mode and Step increment buttons. That'll work just fine. Thanks very much Hood.

Thanks to you, too Brian.
I try to stop the machine with the space bar and let the machine stop normally as in a pause. Occasionally, like when I try to restart and the thing starts somewhere other than expected I hit the "esc" key to slam it to a stop. When that happens I usually need to go back and reset my machine zero's cause it really stops fast and loses position.

Hey Brett:
Thanks for the reply.
I am familiar with the jog settings and I've got the slow jog set to 10%. However, it still seems "touchy". I've really got to tap the key quickly to get a small movement and even then it jumps about .003-.004. Takes a number of tries to get the machine where I want it. Makes it a bit tough to find an edge with a disc type edge finder.
Just thinking about this, I have the debounce count set at 100. Wonder if that may make a difference? I'm not at the machine right now but I'll have to give it a try reducing the value to something less than what I have now.

General Mach Discussion / Restart issue + jogging question
« on: March 01, 2007, 07:54:11 PM »
Hi All:
I've got a problem with restarting a program.
I've included a similar program with the same type of subroutines below.
The problem is that I've had to stop the program in the middle of a drilling operation.
When I try to restart, the software starts at a place higher in the program and trys to do that operation.
Any clues?
Also, is there a way to make the jog keys be less touchy? When I want to jog to a particular location, I find myself going back and forth and tapping the arrow keys just the right amount. It's like the machine moves a lot quite quickly with just a small tap on the key. I don't really want to increment just one step for each key stroke but I would like it not to jump like it does.
Thanks
LEW

General Mach Discussion / Variables
« on: March 01, 2007, 05:12:52 PM »
I'll post this here since I didn't get a reply on the Gcode section.
Any help would be appreciated.
Thanks in advance.

Hi:
I recently got Mach3 running. Finding that I need to tweak old programs from AhHa system.
Have a question on variable programming. In the AhHa system I could use a variable name to represent numbers.
i.e. %down=-2.312
I would then call this variable in several places in the Gcode file.
i.e. G01 Z%down
It made it easy to change the Z value without having to find it in the lines of Gcode.
I usually place the variable at the top of the program.
Now, the question. Can I use a variable to represent a decimal number in Mach3?
I know about the pound character (#) but it can only represent an integer. Not a decimal.
Thanks
Lew

General Mach Discussion / Two more questions
« on: February 11, 2007, 10:55:20 AM »
Is there a setting that would stop the spindle after pressing the esc key?
Right now, If something goes wrong I hit the esc key. But, the spindle does not stop. I've got a breakout board with relays on it. I use one of these relays to control the spindle power with M04/03 start and M05 stop.
Also, when I power the system down for the day and then come back and power it up all the axis' are set to zero. If I didn't home the machine on power down, I have to reset the absolute zero's for all the axis'. Is there any setting I can adjust that will cause the system to remember the position just before shut down?
Thanks
LEW

General Mach Discussion / Voice question
« on: January 30, 2007, 09:29:49 PM »
I've been going through the pdf manual for Mach 3 and ran across the voice function. If I'm reading it right, a person can initiate a wav file to audibly draw attention to a trigger. Perhaps a machine pause or reset needed or limit switch triggered. Can anyone tell me the details of calling a wav file? Can it be done from within a gcode program. Specifically, I'd like to call an M01 (program pause) and give an audible command like "change the part" or "change the tool". Can this be done? and, if so, how?
Thanks
LEW

« on: January 26, 2007, 06:48:35 PM »
Thanks, Sid.
I found the setting under ports and pins in the spindle section.
It was set at one and I changed it to zero and it worked just fine.
