Tweak: I don't see any G2 or G3 in your tap file. So I have to think that is your first attempt at your bike cutout.

If you download either of the DXFs in the above two posts, you will see the lines have been cleaned up.  They have arcs, so they should cut nicely.

Thanks for that Andrey

Does that mean that the  ShuttleRU_LCD is no longer available?

Thanks Tweakie

Converted it to DXF.

I have been playing with the engraving plugin.   Slowly making progress.

Had a big leap forward when I resized the picture to the engraving size before brining it into the plugin.

Thanks Tweakie

I will continue to play around with different power and speed settings.

And I will cut rectangles rather than circles.

I had read that plastic film should be removed before cutting and paper should be left on.

Do you have that bicycle file?

Your website does not have any pricing.  And the pricing in this thread is from December 2010

Can you tell us the cost.

I don't believe that is my problem.  I am cutting test circles using G2 and G3 commands.  So movement, in theory, should be as good as it gets.

I would love to have a go at those bicycles.  Do you have a DXF or similar?

I have tried to take a picture but it is poor.

By the way I am not referring to the one large mark.  That is where the cut starts and stops.  I can use strategies to minimise that.

Cutting acrylic, it cuts great but I am getting lines on the cut.  I think you call them striations.

Can you suggest a strategy to eliminate them?

Tried a combination of power and speed settings, but to no avail.

Just got in from the shed. (its getting late)   Been cutting and engraving.    Woo Hoo!!! 

I worked it out before seeing your post.  I am using Output1, not Digital Trigger, for both vector cutting and engraving (with the plugin).  Only one profile.  I hope this is right.  It works anyway.

Using M10P1 / M11P1 for vector cutting.  Had them around the wrong way at first.  Doh!   

The Vectric PP worked fine so far.

"............Output #1 is mapped to the LPT parallel port pin that is used to fire the laser (the P# relates to the Output Pin#)"

Output Pin# is confusing.  Don't you mean Output#, which can be mapped to any output pin on the LPT?


"............. buffer and to ensure a proper 5 Volt logic switching, for the laser PSU, from the parallel port output which could possibly be 3.3 Volts)."

I am using one of Peter Homman's BoBs which buffers the outputs, so no worries there.

Anyway I am very happy.   Engraving results are not great yet.  Lots to learn.  But at least it works.

Thanks for the help,

Greolt

How do I set up for M10P1 / M11P1 and or E1P0 / E1P1?

"Output 1" or "Digital Trigger" or something else?

And is it different for vector cutting and the engraving plugin?

I have the laser firing manually and got the mirror alignment fairly good.  So I am dead keen to try it out.

I would be grateful of a copy of your Vectric PP if it is to be shared.

Yeah no problem.   But you better wait until I get a chance to test it.

And besides, I just realised I made a mistake and was fixing it when you posted.
