General Mach Discussion / Re: Auto Tool Zero for XY&Z?

« on: June 24, 2010, 03:25:17 AM »

Hi,

Very interesting question - I just tried this and it seems to work OK.
I presume GetVar(2000) would return the X and GetVar(2001) the Y positions.

General Mach Discussion / Re: QUESTION ABOUT FEED HOLD and spindle stop

« on: June 24, 2010, 02:12:28 AM »

Hi Rene,

I have to admit this is above my head - as much as I would really like to understand Mach / Sewing / Embroidery machine control, as yet, I have no practical experience of this usage. (I do read all related posts here and on the zone in an attempt to get an understanding but I think there is no substitute for practical experience - I have just got to build one of these machines and try to get Khalid to share his software).

I do favor the usage of VB screen buttons to make the Mach screens more suited to an actual machine and because these buttons are so easy to re-program 'trial and error' can be used for the operation sequences entered into the buttons to find / establish the perfect combination.

VB and the development of wizards / Re: Y, U, V Change X DRO

Hi Csaba,

Perhaps someone else can figure this one out but I really can't understand exactly what you are doing or just why you would use multi-axis software / GCode just to control one machine axis.

I know it's not resolving your problem but I would like to understand (assuming it's not totally beyond me) exactly what you are doing with this machine.

Hi Rene,

I think you have answered your own question here. The usual sequence is :-

Feed Hold - to stop program
Stop - to stop spindle
Start Cycle - to resume (but you have to restart the spindle manually)

If you feel inclined you could create two extra VB screen buttons to perform these tasks, perhaps in a better way (Pause / Resume).

Hi Csaba,

Not quite sure what you are saying here.

Y300 will move the Y axis and DRO
U300 will move the A axis and DRO

Could you perhaps explain in more detail please ?

Dave has an excellent memory - Auto Calculator is under the 'Operator' menu tab.

Show"N"Tell ( Your Machines) / Re: The Laser Project.

« on: June 23, 2010, 05:06:09 AM »

Thank you guys, you are most kind.

This project still has a way to run so, with your permission, I will continue to bore you with pictures of my progress - The adventures of Tweakie.

The next part of the project is to add some form of temperature control / monitoring and provide for an automatic shut down in the event of tube over temperature. I am currently only running the laser for relatively short periods of time and at low power settings whilst monitoring the temp rise with a handheld surface contact probe. I perhaps should admit that the forced air radiator I am using is a bit overkill and so far I have not yet recorded a temp rise above ambient. However an automatic system will enable longer operational periods of the tube without causing any anxiety and it just has to be done.

General Mach Discussion / Re: Enternal E-STOP Leds

Hi Johnv,

As Ian said Mach deactivates all outputs in reset. So when Mach is running your output #2 is used to keep the LEDs off - when Mach is in reset the output #2 is deactivated and the LEDs come on. Simple.

Hey Guys,

More stuff - latest picture, taken this week.
Shows the new laser air assist pump and spindle VFD, stowage for spindle motor (when not in use) and change to laser current display - the rotary axis is only fitted occasionally and can't really be classed as 'bolted on'.

               

You guys must be getting fed up with this thread by now - I must think of something new

Hi Johnv,

I think PeterF is correct you need to do a little reading but to get you started......

I haven't actually tried this but the following code placed in the macropump should do it.

If GetOemLED(800)=True      'reads the reset LED
ActivateSignal(OUTPUT1)      'turns on output #1 (or whatever output you choose)
Else
DeActivateSignal(OUTPUT1)    'turns off output #1
EndIf
