@NVJims You can upload my default parameters from the machine menu, my firmware is already pre-configured for these machines and includes homing and other features ready to go.

@hami 0.6V should not cause any overheating, even on a long job but it's higher than typical which would indicate higher mechanical friction.

@michael2019 Yes. You can set a Z-Safe height.

It will retract to the Z-Safe plane before moving from one path to another, you can use this to avoid clamps etc.

Posso usare t2laser per laser ço2 cinese 40w ?

I'm not sure what this has to do with EleksMill, but yes it's possible.

T2Laser outputs G-code (Grbl based is recommended) so any controller that supports this standard will work. The Chinese K40 machines use proprietary cards but you can swap them with an Eleks or other controller that supports G-code.

@icejoker The power switch?

No, The mechanics are smooth. I have already found a replacement, and that works fine. Thanks.

@swarfmaker T2Laser will generate 2.5D or 3D G-code and run the machine (no other software required).

You can use any image, as a quick example I loaded a jpg and inverted to make it a positive.

Note: The 3D simulation was done using ncviewer (the viewer in T2Laser is 2.5D only)

@bug You need to use X, Y1 and Z. Y2 is a reversed output of Y used for machines with dual Y motors.

@Zax Thank, I will try and out and let you know if I get it working.

@amirazimi.y The absolute accuracy of the machine is 2.5um but due to the use of a pinion gear and belt on the X-axis it's positional accuracy is significantly lower, around +/-12.5um or 25um total. This will depend on bit loading and other factors, so for PCB drilling (no side loads) you could well achieve 5um accuracy.

In any case those 50um spaced holes would have a 10% tolerance (best case) which should be acceptable.

Thank you!!!

@MicMods There are several ways to see the image size, so you should make sure it is correct.

On the design screen you can press the 'i' key to turn on the information overlay. On the laser controller you can check the simulation "view" to see the size You can run the trace frame feature to have the machine show you the perimeter

If the output size doesn't match what T2Laser shows then your laser needs to be calibrated, you can do this from the menu.

I understand the concept of a Z-axis table, just not why you can't do as I suggested and use a stepper driver and run it from the Z outputs or better yet just replace your 2-axis Mana SE with the 3-axis Mana CNC board or similar. Then you would be able to raise and lower using the Z jog controls or even from the G-code.

T2Laser supports this already, so you can cut thicker materials by moving the Z-axis for each pass. Say in 0.25mm steps until you cut all the way through the material.

@Wayne-K It's a test board, usually to check a laser is working. It puts 5VDC on the TTL signal to enable the output.

@yippiez Sorry I don't know this software, I only support T2Laser and other general machine questions if I can help. It sounds like the G-code is not optimized.
