Hi Craig,

The train image was taken from the thread mentioned in the last post but if you PM Jeff directly (JJWMACHINECO) he could, I am sure, provide you with a better resolution image for your palm engraving.

Hi Bartabac,

I am pleased that you are making progress with your laser control. Perhaps you could post some pictures of your work, setup etc.

I am following with great interest the work being produced and shown by the guys in the Diode Laser thread here http://hobbycncart.com/forum/63-151-11  Really excellent work.

A couple of images I just had to try with the CO2 laser – Jeff’s train engraving was produced using GCode generated by John’s PicLaser software using the Sierra algorithm and Amator’s craftsman engraving was reproduced using the Mach3 plugin.

Hi Bartabac,

Some while back I did try using the Mach3 PWM output for laser control but it was not very successful. Perhaps it depends on the type / specification of PC used but I found that the small, periodic, frequency variations of the PWM produced quite large changes in laser output power. This is not noticeable when cutting but it can spoil engraving work etc. so I abandoned the idea in favour of manual control for maximum laser current.

Hi Art,

Sorry but I can't tell much just by 3 lines of code.

Zip your GCode file.
Click the Reply box below.
Select Additional Options.
Choose File (your zipped GCode)

That should do it.

It would help if you could zip and attach your GCode file that is causing the problem.

General Mach Discussion / Re: z axis deep problem

Your pocket.tap file cuts 0.5mm deep here when setting Z zero at the top surface of the work.

The only thing I can suggest is that you check the calibration of your Z axis (steps per unit).
Move your Z axis near to the bottom of its travel and zero the Z axis DRO, mount a steel rule vertically next to your axis, note the reading and in the MDI line type G0 Z100 (or whatever) and check that your Z axis does indeed move up 100mm.

Hi Dani,

As Terry said previously - If you program lead-in / lead-out (in the case of holes with the same radius as the hole) at the CAD/CAM stage then there is no problem with tool rotation within the work.
