FAQs / Re: Wiring Limit, Home and E-Stop Switches

« on: April 13, 2016, 10:59:04 AM »

Not much help really but the only thing I can think of is that your wiring is incorrect or else you have the Active High / Low set incorrectly.

Way cool guys,
If I only had a laser and the time to work with it. Maybe when the other 40 projects are done.

Mike, how can you possibly live without a laser ?

General Mach Discussion / Re: what program can I use to layout my own text

« on: April 13, 2016, 03:23:09 AM »

Take a look at Vectric software http://www.vectric.com/
It is not free but it is easy to learn / use, has suitable Mach3/Mach4 post processors (which create the Gcode) and has 'try before you buy' demo versions just like Mach.

Excellent work Art, I look forward to seeing more of this.

The 8000 mm/min is particularly impressive, that's galvo performance. 

Are you using a variable PWM (linked to axis speed) to provide the Acceleration / Deceleration changes in laser output power ?

Mach3 and G-Rex / Re: Mach3 Beginner Help

« on: April 12, 2016, 08:32:56 AM »

You are missing one or more of the graphics within the MillBitmaps folder. You could try copying the background…jpg and various .jpg’s from the other bitmaps folders into MillBitmaps and see if that resolves the issue.
Alternately contact the suppliers of the machine who are probably the only people who work with Artivision 2.0 (whatever that is).

Could it be that you are running Mach3 in Demo mode ?  (in which case it will only process the first 500 lines of Gcode).

Try putting the G20 on a separate line


Message( "Auto Zeroing..." )
Code “G20”
While IsMoving()
Wend
If IsSuchSignal (22) Then
code “G31 Z-1 F10”
While IsMoving()
Wend
Call SetDRO( 2, .996 )

General Mach Discussion / Re: Using DIR pin of unused axis for synchronous switching

« on: April 10, 2016, 02:11:55 AM »

One possible solution perhaps ?

By using an external controller (such as a PLC) it would be possible to count your X axis step pulses. You would need to know, in advance, just how many X step pulses had to occur before your phantom axis DIR pin is activated but this method would allow the X axis to make it’s journey without any interruption.

General Mach Discussion / Re: New people welcome !! Come in here and introduce your self!

Thanks Tweakie, but why have the USB socket on the board if its not used, and is the 15 D socket no use if I get a gender bender to connect it to the LPT1 on the board.

Regards Pirate

The USB socket is just to provide the 5Volt power from the PC to the board - the board is driven by the LPT port and should be connected with a 25 way, LPT parallel port cable.
Gender benders will not work in this instance.
Mach3 does not run successfully from a laptop.

Hi Pirate,

Welcome.

Sounds like you need to get an older PC (perhaps second user) which has an LPT parallel port.
Mach3 does not run successfully from a laptop unless you use an External Motion Controller (such as the ESS http://warp9td.com/ or similar)
