That's exaclty what dynamic laser mode is supposed to fix, are you sure you are using M4 and not constant power mode M3?

Laser mode is something entirely different.

It's a DXF, just click Import DXF from the File menu or right click the open icon.

Here's a DXF, maybe that will make more sense.

Are you somehow expecting the hand to be the size you enter?

You are entering a size for the entire image, the hand is in the center and about half the height.

When you trace it, the white space to the upper right is ignored so the overall "size" is reduced but the hand is the same size.

Why don't you crop the image to the hand so you can scale it accurately or is there some reason you are doing it like this?

It's going to be faster and easier to support via email.

Is it coming out the size it shows on the simulation "view"?

You have an image that is sized correctly, you trace it and then output the result it will be the same.

It would help if you post the original image so I can see what you are doing wrong, also you don't need 0.1 resolution on an image the size of your machine.

You don't need to set a machine size then, there's no benefit without home switches.

Is the rest of the image blank?

The trace is only for objects, and then view is showing the extents.

Do you have home switches?

If not, then setting the size in the parameters makes no difference as the machine has no reference as to where it is.

These are the Grbl parameters, use debug mode in T2Laser to send them to the machine or create a custom Sketch at these dimensions and then click Machine Size in the advanced settings menu.

$130=600
$131=500

The delete key removes the previous trace, but I am not sure you are using it correctly.

If you want to trace the entire image just use auto-trace (right click the trace icon).

Manual trace (that you are using) is typically used for contour cut out or tracing a couple of entities, clicking the same twice would create an additional vector path.

You are using the trial, it is limited to 10,000 lines of G-code. Once you register there are no restrictions.

It is moving much slower with the old Benbox firmware, but because Grbl 1.1 has improved motor control it is faster but also smoother. You can slow down the acceleration and achieve the same but you should not need to, the default values are not that aggressive. There's an option in the menu for reduced acceleration if you choose, but just like deactivating bi-directional mode these are band aids and not real solutions for a mechanical issue.

The motors are connected to the same driver so if they don't move the same the problem is mechanical. You either need to adjust the axis (gantry) or the belts.

That looks like backlash, tighten the X-axis belt. It is much easier to setup a machine using vector, such as the circle in the Help / Samples menu. If the ends do not meet up you know it's backlash, it the shape is not round (oval or uneven) it is usually a problem with the wheels.

In T2Laser you can also disable bi-directional engraving to test it, if that fixes it then the problem is backlash. You usually leave this turned on for speed but it's a good way to test.

It only happens on the first few pixels when the machine is accelerating to the feed rate, I assume you are using a constant velocity during the scan (and not increasing the feed rate to quickly skip gaps).

Use dynamic laser power.
