I'm pretty sure its not noise.

Hi Bob,

If your inputs wiring (by this I mean all your inputs to Mach3, not just the E-Stop) are as I described previously then I would be inclined to agree with you.

No...its not a wiring or power supply issue.

Sounds like electrical noise Bob.
I recommend that your inputs wiring should be good quality, twin core, shielded / screened, cable with the shield connected to Earth at the controller end only.

Hi Vogavt,

Thanks for reporting back on you progress with this. Interesting about the -2.7 volts output from the C10 - I have absolutely no idea what is going on there.

I think it is just fine to continue using this thread for the discussion.



Just some basic notes regarding driving an electromagnet from a stepper driver which may help others that follow to grasp the principle being discussed here...

1) If an appropriate a.c. voltage is applied to an electromagnet it will be energized.

2) If the frequency of that a.c. voltage is progressively increased there will come a point when the magnet is no longer energized - it will drop-out or stall (in exactly the  same manner as a stepper motor stalls). This principle was used by Andrea to drive his magnet and initially paved the way for us all to follow.

3) The set-up is arranged so that the work is only impacted when the magnet stalls.

4) In operation the plugin scans an image and outputs a series of short (40mS) pulses, the repetition rate or frequency of these pulses varies in proportion with the individual pixel value of the image being processed. The greater the repetition rate the more often the magnet stalls and the more it impacts the work.


Hope this helps,

Tweakie.

I think everybody each has their own preference.

If it's any help, I use R3.043.056

Where might I be able to get a copy of the older version? I found some links in old threads, but they don't work anymore.

If you look in FTP Downloads / FTP Server - Main Menu / Mach3  you can find all the available versions.    http://www.machsupport.com/software/downloads-updates/

Mach SDK plugin questions and answers. / Re: Impact engraving plugin

I was wondering since I'd purchased the driver board listed earlier if I could simply connect a laser like this one from jtechphotonics up to the board and simply use a toggle switch to control either the laser or the impact engraver.

You could use either a magnet or a laser with the plugin but the device drive requirements would be different for each. For example, the diode laser would require it's own, dedicated, current controlled power supply.
