@sk2 T2Laser follows the sequence that is written in the DXF, if you draw using polylines (connected) then most programs will output in that order but if you have discrete lines unconnected it probably uses the draw order. If you upload or email me an example I can easily check it for you.
Again, although it's a CAD problem and should be fixed in the export T2Laser has an option to fix this. It's called the DXF Optimizer and has several settings, the defaults will do what you want.
@sk2 The dots are from your pen bleeding, ball pens use ink so it will soak in very quickly. It is difficult to improve as these machines use the older Grbl 0.9 firmware, perhaps increasing the acceleration parameter would help (I think this is possible with the older firmware).
You can do this using debug mode. Type these commands in the box and press enter.
@siggidrechsler It sounds like your laser and mouse are using the same USB port, this will cause problems with the laser as well. They may be on separate physical ports but internally your PC probably has a USB hub so both are using the same.
Do you have another USB port to use?
Ja, super genau so war es, vielen Dank für die rasche Hilfe!!
@Piramidowy I would be interested in that firmware if it works. I have only tried to implement CoreXY, Servo and Homing and there was no way to get the size within Nano limitations but for your application that should be possible.
Yes, I can add a servo mode to easily implement the pre and post dwell although I prefer using a post processor than modifying the base G-code (this keeps it standard).
@tgrott If you have home switches the machine will have a constant reference but most machines do not come with them so machine 0,0 is set when the controller boots-up. So if you always move it back to your 0,0 before disconnecting the laser then it will keep the location unless bumped. I recommend home switches especially if you are going to use a grid or jigs.
A grid should be a vector, so you want to save as a DXF. The objects, hatch etc needs to be converted to paths before you export. Click Path / Object to Path. If you need help, email the SVG to me and I can walk you through the steps.
15000mW or 15W is likely the electrical input power and not the output power which is likely 3W or somewhere around there. It should be able to cut 3mm laser ply with 6 or so slow passes using air assist. Powder coated mugs may be a challenge depending on the color and reflectivity of the coating.
