Show"N"Tell ( Your Machines) / Re: DC-K40 Laser conversion issue
« on: August 06, 2014, 01:56:52 AM »
Hi Guys,

It sounds to me like you are experiencing a difference in potential between the GND connections between your computer LPT port and the machines PSU GND.

The LPT port’s pins 18-25 are GND and one of these pins must be connected to the laser PSU’s GND point (adjacent to the TTL(L) signal input as shown in my earlier diagram),

This should resolve the problem of the laser firing when it should be off.

Pressing the Tab key brings up the pendant - reduce the Slow Jog Rate %  :)

I will be ordering a new stepper, but this one has 4 leads and the new one of the same model
that Oriential sells now has 6 wires...will it be compatible with the other 4 wire, or do I need
to buy 2 new ones???

Hi Preston,

I don't know if this helps...

even if i disconnect the BOB and use a voltmeter to watch the parallel port pins i see the power turn off when starting mach 3.

Are you trying to power the BOB from your parallel port ??

Hi Golash,

Normally, Distance Mode would be set to Absolute and IJ Mode set to Incremental.
Did changing the IJ Mode to Absolute solve the problem with running your code ??

Hi Mrputz1,

You can download the Mach3 version of your choice, copy this download to a thumb drive then install it on any computer. The Mach3 license can be copied to your thumb drive and then copied to any computer in a similar manner.

Hope this helps.

Share Your GCode / Re: Inkscape with GCode tools
« on: July 31, 2014, 07:48:14 AM »
Hi Frank,

The code you are generating (Inkscape / GCodetools) has the origin offset from the actual job position by the amount you see when you load the code into Mach3.
Go back to your CAD/CAM software and reset the origin / material size etc. so the origin (X zero, Y zero) is adjacent to (or centre of) your actual job then regenerate the GCode toolpath for Mach3.

(sorry if this is not easy to understand but it is one of those things that is easier to do than it is for me to explain).

Hi Mike,

You have my sympathies, I managed to get in a similar situation a year or so back and know that you could easily spend many hours trying to find the problem. Generally when things go wacky it is a corrupt .xml but it could equally be somewhere else.

My best advice would be to copy your entire Mach3 folder to a backup folder (so it can be used for reference if necessary) then hardcopy all your Mach3 settings for your reference.
Uninstall Mach3 and delete any remainder Mach3 folders from your HD.
Perform a fresh install of your chosen Mach3 version and then enter all the settings from your hardcopy (do not copy and paste existing .xml’s or any other info – enter all the required settings manually).

I appreciate that this may take some time but, trust me, in the long run it is far quicker than chasing your tail trying to find the problem.

question should i be getting a different splash screen every time i start mach3

Mike,

The splash screen is selected at random from those available (you can even add your own) so on startup you could easily have different splash screens each time.
