Hi Mikee,

I think we are at crossed purposes here. It is the ceramic tile which needs sealing (to keep Sam's bleach out  ) not the laser lens. 

Does the waterfront property come expensive ?

If you post the xml it can be checked. (rename a copy of your xml to MrWilson.xml : use additional options : choose file ).

General Mach Discussion / Re: What have I got and what do I need

stevet.machine,

Take a look at Gearotic Motion http://www.gearotic.com/

Art is very into wooden clocks and he is continually developing this product which just keeps getting better and better.
I purchased this last year and it is just brilliant for all sorts of gears and most important of all, it is not expensive.

General Mach Discussion / Re: 24 volt proximity switches

« on: July 14, 2011, 07:16:48 AM »

Hi Will,

If you take a look at this document (Section 7) it gives details of proximity switch connections for 12 & 24 Volt / NPN and PNP versions. http://cnc4pc.com/Tech_Docs/C10R10_USER_MANUAL_V2.pdf

Hope this helps,

Thanks Mikee I didn't know that.

My main problem with this as a process seems that it is extremely difficult to get enough dye to penetrate through the micro-fractures and into the substrate. The final image is just not bold enough (compared to screen printing).
Perhaps I should Autoclave a couple of tiles to make them "thirsty" prior to applying the dye 

Anybody have any ideas on this please.

I am pleased you got it sorted.

I can see I'm going to have a very long learning curve.

Iv'e been here 4 years now and I am just starting to scratch the surface - Mach is vast, devious and cunning.

The info in Chris's PDF here http://www.machsupport.com/forum/index.php/topic,15457.msg103687.html#msg103687 may be useful to you as it covers the Mach settings for the PWM output etc.

Hope this helps,

General Mach Discussion / Re: Mach 3 Scaling Problem

« on: July 13, 2011, 09:38:35 AM »

Hi Ukie,

Your Steps Per unit are probably set wrongly in Motor Tuning (perhaps you are using a reduction gearing on your motors or perhaps you are using Microsteps and  have not allowed for this ?)

As far as scale is concerned;
You can see the size of a loaded GCode program in the Toolpath page under Program Limits.
On the main page you can adjust the Scale DRO's (currently set to +1.000) and for example +2.000 (press return key after entry) for X Axis and Y Axis will produce double size and you can check this in the Toolpath page under Program Limits (you need to click the Regen.Toolpath button).

Hope this helps.

LameIII,

Try replacing the second G4 with a While...Wend as follows.

(these macro/scripts run at different speeds to Mach and under some circumstances everything gets screwed up but different PC's and different versions of Mach can all respond differently). 


CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later
PlateThickness = GetOemDRO(1151)

If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P2" ' this delay gives me time to get from computer to hold probe in place
Code "G31Z-1 F4" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness
While IsMoving() 'wait while it happens
Wend
Code "G0 Z.5" 'put the Z retract height you want here
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Code "F" &CurrentFeed 'Returns to prior feed rate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
Exit Sub
End If
