Show"N"Tell ( Your Machines) / Re: The Laser Project.

Hi Obal,

My current DotG post processor is attached. This is for ‘dot mode’ operation of both laser and impact magnet and will produce three lines of GCode for each ‘dot’ (the laser / magnet is only fired when the X axis is stationary).

If it is of interest, there is some more information (in English) relating to the use of DotG here http://hobbycncart.com/forum/61-146-1

Hi Graham,

Building or Buying a Wood routing table.. Beginnners guide.. / Re: Hardware problems

It depends if you are to use GCode to drive the laser - the laser thread has most of the details (you will have to skip through the boring parts because the thread has got a bit long now). http://www.machsupport.com/forum/index.php/topic,12444.0.html

If it is a laser machine (which use a form of HPGL) this forum may be of interest to you http://oplaser.co.uk/opsupport/

I would be most interested to hear how you get on with the laser.

Pretty bad luck, I would have to say    but perhaps that's the way luck goes sometimes.

I know it's no help to you but you would not be the first to get bad stuff from China.

When setting everything up you must ensure that the driver's motor current settings do not exceed the motor's rated current otherwise you will fry the driver or perhaps damage the motor - the stuff from China rarely has any tolerance for errors. Having said that I have been using a Chinese driver board for some years now without any problems (perhaps luck is involved here).
Also - perhaps a better quality BOB may be a good investment.

LazyCam (Beta) / Re: Text workflow advice for instructor

Hi bradallen,

Another, relatively new, free, software you may wish to consider is F-Engrave http://home.comcast.net/~sskroch/Fengrave/fengrave.html
This can import any / all of the Windows TTF fonts and is excellent, not just for engraving and V-Carving but also profile cutting etc.

Hi Dminnery,

Thinking more about this.....

As the Romaxx is a pretty robust machine and 0.1" step-over is not an unrealistic figure it may be worth checking your machine for tightness of all parts and perhaps also the front bearings of the Bosch Colt.

Hi Dminnery,

My fist action would be to reduce the step-over size associated with the selected tool in the VCarve tool table and see if that improved the situation (obviously you would need to create a new tool-path at the new settings).

Just a thought.

Hi Mads,

There are quite a few free PCB routing programs about and this may be of interest to you http://www.pcbgcode.org/

Hi Mads,

The machine supplier says it runs from GCode and LazyCam outputs GCode so there should be no problem using this machine with Mach3 for routing PCB's.
