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.
@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.
@nickolas you can flash OptiBoot onto your Mana SE Nano with another Arduino using the process shown here https://youtu.be/oce7D72Mdwo . . . this doesnt need the ICSP pins to be available on the Nano, but uses standard pins.
Once you have done this (and gained the extra 1.5k of memory) you can flash GRBL 1.1f, with coreXY capability (activated using config.h), with no problem and have the full capability of the latest GRBL version (i.e. Laser Mode and PWM output for controlling your laser or Pen Servo) . . . there is also a version adapted specifically for Pen Plotting/Servo output available here https://github.com/bdring/Grbl_Pen_Servo
@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.
@nottingham82 I have the problem where the 4 wheels for the z axis are too tight, this makes the rotar stuck when it has to laser small objects because there is not enough speed to get over the miniscule bumps on the metal bar in which the wheels are rolling. Are there any known fixes for this? Or should I just use a file to make the screw holes a bit bigger, so the wheels are less tight to each other?
