Enable soft limits $20=1.

You need to enable debug mode, that will provide a window to type commands.

It looks like you already enabled the switches, what is it you need to change?

Use ballscrews for a laser, you need the speed rather than the torque.

T2Laser does have a calibration feature which updates the firmware automatically. You can also calculate the steps yourself and enter them using the $ commands, but in this case I don't think 0.2% is an error due to the motors but as Ralph said it's probably mechanical.

0.2%  ???

So on a 100mm shape it's 100.2, that's probably just the width of the laser beam.

T2 Engraving / Re: Multipass on DXF file?

The default laser power for green is 20% of laser max, you could use Red for 80% or you can change these in the menu and get 100%

You could enable Absolute DXF Colors and set it to 0, then every color would be 100% or alternatively if you use a color that isn't in the T2Laser palette it will display as black but will engrave only, the problem with Inkscape is how it translates colors.

T2 Engraving / Re: PCB engraving from SVG

I think he was using Gerber format which is similar to SVG in that it's a vector format with some vectors being raster filled. I convert the file to raster as that's the best way to get a filled result.

I'm not sure why you had a problem setting the color but otherwise everything looks fine.

You need to remove all fill and set the stroke color as that's the vector path. It loads correctly.

If you want to raster the clipart and then cut you could either add a pseudo fill (hatch) in Inkscape or use a raster and trace the cuts using Sketch Plus.

If you export the PNG at the required size and resolution it will import correctly, and engrave in raster. If it were an SVG it would still need to be either pseudo hatched or converted to raster so there's no advantage.

As long as the software is open source which of course T2Laser is not.

You are on the right path, Inkscape can easily convert the SVG to DXF.

Is the problem that you are expecting it to be filled like a raster image?

If that's what you want you can use PNG as a vector format would only export the paths (remove the fill and set stroke to 0.1 and you'll see what it really looks like), the same as what T2Laser loads. You could also add hatching in Inkscape to pseudo fill the vector if you prefer, the same can be done by using the raster format and tracing with hatch fill enabled in T2Laser.

Adding SVG support requires a plug-in and for a commercial license the cost would be excessive.

I'm not sure what you mean, as in change the color of the DXF paths? No. You would do that in the CAD before exporting the DXF.

That's why I prefer the 2500mW for engraving, the spot is round and 1/4 the size so power density is actually higher than you would expect although the 5500mW still has the advantage for cutting.

You can't trace a DXF as it's already vector, tracing is the process of converting raster (image) to vector (path).

The feature you want is called Engrave and Cut in the DXF menu.

o   Used with multi-pass. The first pass is engraved (all colors) and subsequent passes are cut (Black only, other colors are ignored)

You can also duplicate the paths in the DXF (with engrave and cut disabled) so you can engrave 2 passes and cut 6 or whatever you want. In my CAD program there's a copy in place feature which duplicates the selected path.

There are replacement lenses but a few years ago I tested several and found the difference was negligible, it's been a while but I think it was the G2 that performed slightly better. I tested with a 2.5W for engraving so the 5.5W may perform differently.
