VB and the development of wizards / Rookie needs some help.

« on: December 07, 2011, 09:25:25 AM »

My VB skills are not so hot but I understand the idea of basic programs. Anyways I need some help with a script.

What I'm trying to do is when a tool change is initiated I want Mach to look at the current tool and the tool being called, and if they are the same, to ignore the tool change and start running the program. If they are different, go to my selected tool change position and then wait for a cycle start. I have the code working like I want except for a little hiccup. If I have the setting to "Stop spindle, wait for cycle start" it won't automatically start the program if the tools are the same value. If I have it set to "AutoTool Changer" it works great except when the tool values are different it goes to the tool change position and then immediately starts running the program, not giving me a chance to actually change the tool and then hit cycle start. Any help will be greatly appreciated.

Here's what I have

Sub Main()
X = GetUserDRO ( 1200 )
Z = GetUserDRO ( 1201 )
NewTool = GetSelectedTool
OldTool = GetCurrentTool
If NewTool = OldTool Then
   Exit Sub
Else
   Code "G53 G0 , Z" & Z
   While IsMoving
   Wend
   Code "G53 G0 , X" & X
End If

End Sub


Thanks

VB and the development of wizards / Need help with a simple macro

« on: September 13, 2011, 06:13:21 AM »

In my M6Start macro I have this code.

X = GetUserDRO ( 1200 )
Z = GetUserDRO ( 1201 )

code "G53G0 , Z" & Z
While IsMoving
Wend
code "G53G0 , X" & X

Basically it just looks at two DRO's I have on the screen and moves the machine to whatever I have in those DRO's. My problem is, I want to move X&Z at the same time. I've tried all different configurations and I can't seem to figure it out.

I have it working right now with this code.

code "G53G0 , X-.125 Z-10.75"

and it works great. However if I want to change the values I have to edit the macro.

Any help is appreciated.

Thanks

I'm having noise issues with false triggers on my input pins. Is there any settings to filter the noise? Kind of like the debounce?

Thanks

Modbus / ModIO Expansion Limit

« on: November 23, 2010, 11:19:54 AM »

I'm getting into the world of PLC's for my current job and was recently turned on to Homann Designs ModIO board for Mach3. I've watched the videos on setting up the ModIO and I have to say I'm really impressed with the amount of versatility you can achieve with this setup.

I'm left with two questions though.

First:
I'm assuming since I haven't seen it mentioned anywhere, you can't use ModIO to send step/dir signals to stepper/servo drives. Is this correct? If so why not?

Second:
What is the limit on expansion ModIO boards?

Thanks

General Mach Discussion / Rapid OverRide

« on: July 22, 2010, 09:48:10 AM »

Why do none of the lathe screen sets available have the ability to change the rapid speed. Only Feed Rate and Jog%, am I missing something here? I'd like to have what the Mill screen has with the slider. I don't really like going at full speed when running a part for the first time. Help?

VB and the development of wizards / Need Macro Help.. G77 MachTurn

« on: May 21, 2010, 10:20:31 AM »

Hello, I've been toying with G77 in MachTurn and I came to find that the one supplied with the download of Mach3 does not work properly. I found an edited Macro  Here (Post #6) I replaced the stock Macro with this one and everything seems good. Except for one small issue. The new Macro doesn't do a spring pass, only when written in a program. If you type in a G77 blah blah blah into MDI then it works properly. Seems odd to me but I'd like to see if it can be fixed. Spring passes are great especially when boring.

SmoothStepper USB / Smooth Stepper Port2

« on: March 10, 2010, 11:12:11 AM »

Hello, I'm using the SS and the C25 from cnc4pc.com

I can't seem to get any I/O's on port2. Is there somewhere you have to enable it?

Port1 works great. Port 2 is dead.

Thanks

General Mach Discussion / Servo Humming

« on: March 05, 2010, 01:03:41 PM »

Hello, I'm finishing up my first Servo based CNC conversion on a Mazak 14x40 lathe. My question is my Z axis servo has a humming coming from it, that almost sounds like a heart monitor. It hums, then, its almost like its beeping, but very quietly. Is this normal for servos?

Specs:
Smooth Stepper with C25 BOB
Gecko G320x Drives
Mach3Lathe
Keling 850oz motors
72v 20A PSU

Thanks, Scott

PoKeys / Pokeys with Mach Turn

« on: February 10, 2010, 07:56:36 AM »

Hello, I have the pokeys plugin and software installed on my computer and I'm looking to use it with Mach Turn.

When I open turn, there is no plugin under the drop down menu for pokeys.

Now in the mach loader there is a profile for pokeys, but it comes up for the mill control.

Are these not compatible?

Thanks, Scott
