Hi Guys,

LazyCam is provided free with Mach3 and although this is essentially an unsupported beta product it is still very useful for working with HPGL and .dxf files ( for example - changing the scale / origin or editing the tool paths etc.) then to create the necessary GCode.

For laser profile cutting and engraving I have written a very basic Post Processor for use with LazyCam which utilises the undocumented M11P1 / M10P1 command set.
The laser trigger is connected to a suitable LPT output pin ( I use pin 16 ) then in Mach / Config /  Ports & Pins / Output Signals, Output #1 is mapped to pin 16 ( or whichever pin has been chosen ) and the active Hi / Lo set accordingly. These M commands will then turn the laser on and off coincident with axis movement ( M11P1 = laser ON and M10P1 = laser OFF ).

The feed-rate, in the post processor generated GCode ( currently set to F300 ), needs to be adjusted to suit the application / material and this can either be edited within Mach3 using Windows Notepad or adjusted with the FRO slider on the Mach screen.

For any that are interested the Post Processor can be downloaded from here; http://hobbymaro.puhasoft.hu/Tweakie/Laser.zip. To use, unzip and copy the file ‘Laser.pst’ into the Mach3 folder then from within LazyCam  select Setup / Posting Options and select ‘Laser.pst’ from the ‘Set Post Processor’ options.

Hi otpco,

It could be that your Mach configuration is incorrectly set up in Ports and Pins (port address : motor output pin numbers : active hi / low etc) also have you been through the Troubleshooting guide in the C1 documentation ??  http://cnc4pc.com/Tech_Docs/C1R10_1_USER_MANUAL.pdf

Sorry Dan - nice job you are doing with the lathe. 

Here is a short video clip with the sound of the electromagnet. http://hobbymaro.puhasoft.hu/Tweakie/Impact1.wmv

Hi Dan,

For the purposes of the frequency calculation, I ignored the axis movement time and divided the number of dots by the total time taken.
I have already been asked to make a short video – I will post the link when it is done then the sound can be heard.

btw. Nice job you are doing on that milling machine – very professional.

This was just a test run but I am really quite excited by the results.
The DotG generated code consists of 467,517 lines and with 4 lines of code to produce each dot, the image consists of 116,879 dots which took just 1.5 hours to complete. With a stroke length of 1mm the little electromagnet has now shown that it is capable of producing at least 21.644 dots per second (axis movement time has been ignored in the calculations), which is about double my previously achieved speed.
Instead of sounding like an ASR33 Teletype my CNC now sounds like a Gatling Gun and although not quite as quick as the Roland Metaza it is getting closer.

Hi gtonini,

How does it behave when jogging from the keyboard - do all the axis move in both directions OK ??

Hi Tony,

You would need to check with the makers of the switch mode power supply to be certain but it is my understanding that it is not recommended to do this.
