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

« on: February 16, 2011, 12:16:43 PM »

And I tried it and it goes well, I see strange is that when I very low speed (30cm/min) will not turn on the laser. "Should be activated at any speed?

If the laser was activated at any speed then it would burn when stationary which is not what is required. (The stationary thing is a law of physics which applies to the X Axis changing it's direction)

Hi Larry,

There is a reasonable time difference, I am approx 6,000km due east of you so I get to see the sunrise first

Stitos,

I am not at the same location as the machine but I think this profile is correct.

Hi Stitos,

When raster scanning the axis has to accelerate from zero to full speed at the start of each line and then decelerate from full speed to zero at the end of each line (as defined under the motor tuning parameters). If the power level was not reduced proportional to the axis speed then the laser would cut deeper as it slows towards the end of travel.
Getting the power level and / or feed rate just right perhaps requires a bit of practice.

Same way as posting pictures.
The file must have a name that has not been used before on the forum and a file extension must be from the approved list shown.

If you post your GCode I can check it on my machine and this will at least rule out the possibility of a problem with the code.

Hi Larry,

Something I forgot to mention    is that LazyCam (part of Mach) will also convert your HPGL files to GCode. It takes a long while with some of the larger files but usually gets there in the end. LazyCam has the advantage of allowing easy deletion of unwanted vectors and the redefinition of the origin etc. etc. and may be your best option.

Nice work Barry.
You have been threatening to redo the control box for some time now - looks really neat and ought to work well (don't forget to stick a copy of your wiring diagram on the inside of the door).

Hi Larry,

Target2Gcode is a standalone .exe application - Just place it on your desktop and run it. (as mentioned earlier there are certain HPGL codes it doesn't like and these return an error if they are not edited out which is where the SignGo post processor comes into its own).
The input files need .plt or .hpg file extension to open and the program creates a ....wire.din file which is the GCode. You just need to set the safe Z and cutting depth before creating the GCode.
