General Mach Discussion / Re: If I don't have a none integrated graphics board what happens?

Ray,

Try it an see.
If it doesn't work well then install a PCI or AGP graphics card and see what happen then.
The problem here is that some PC's work OK with onboard graphics and some don't and you never know which sort you have until you try it.

Hi Mike,

Glad you got it sorted and working OK.

The Vectric online help / manual / tutorials are pretty good and should answer any questions you have using VCarvePro. Alternately the Vectric forum is an excellent source of info for all their products.

(it has taken me some 18 months of savings to buy VCarve Pro and I don't have enough left for the manual   )

Hi larry,

There are probably run time files which were installed on my PC which are not on yours thus the error.

Try LazyCam and see how you get on with that.

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.
