no Zax, my machine is too young. That cabinet if for ME!

I was going at 1800 horizontal. theoretically, slowing the speed down should help. I will try that and diagonal.
should I go back to 0.9 then instead of 1.1?

soo yeah 1800 could be the culprit along with a loose belt. 

I like my engravings to actually remove about a mm of wood.  So I go slow.  Usually 750 with air assist so it wont catch fire and tape so the smoke doesnt burn the edges.  But that's just me.  I like it to look almost like I routered it.

The belts don't feel loose. I just tightened them. Outside of some tensioning instrument, what is the best belt tension guage method do use?

Sorry, no scientific method. It's more of a feel thing, light finger pressure with around 1/4" deflection.

Are you sure the axis are tight, no side to side play or twisting?

You can slow down to see if it improves (it should) and also drop the acceleration / deceleration values which helps too, but all these are "workarounds" for an underlying mechanical problem.

If nothing else, get into that cabinet and the lines may look straight!

ok. so here is my second version. I think it turned out a lot better. You know how it is a good idea to make one change at a time? Well, here is what I did (all at once):

  • changed to diagonal engraving
  • changed speed from 1800/2000 to 600/1000
  • burned on cardboard instead of the waste board/masonite?
  • reduced the size by 1/3

I think it turned out good. I plan to make a sign that will max out my A5 machine, but that won't be until next week. It is still -5* and a heat wave is coming. It will get up to 20-30*F (yay) so I should actually be able to stand it in my garage.

It still looks a bit drunk, try reducing the accel/decel.

Enable debug mode so you can send manual commands, then type:

$120=200.000 [press enter]
$121=200.000 [press enter]

If it's a belt tension issue you should expect improvements, if not then it's something to do with the axis or the laser is loose etc.

you might consider doing the sign in slate.  I did one for my gf's sewing room door.  I think it turns out cool.  Wood is a good medium too.

@Zax I agree. It still is a bit drunk. I will look into it a bit more and see what happens. It may have to wait until later this week. What "wheels" do you use for your axis? The ones I have are the basic white wheels that came with the machine. I wonder if that could be part of the problem.

@nottingham82   That sounds like a great idea! now if I could just get my laser engrave to stop getting into my liquor cabinet!!!

only thing with slate is that its dark so make sure its in a well lit area.  In a dark hallway its not very noticeable.

I stated etching the plant leaves. Nice aroma and it keeps them in their pot.

Mechanically my machine is stock, so the same white wheels.

@ggallant571, I think you're confused. The leaves were pot!

I will have to add them to "what can be cut" list.

I am going to do this today. What are the default values?

I use 800 as defaults, but 200 was the default in previous versions (Grbl 0.9).
