@amacin T2Laser will output the size shown, you can check the information overlay or the G-code simulation "view" to see the size it should output. If it is not correct the problem is your controller and you need to calibrate the firmware parameters, there's a feature in T2Laser to do that automatically.

Test a shape from the Help / Samples menu to see if the problem is operator error or the machine.

Good luck

This is the best ever for all of us and there is all product differ from windows to mac but there is also enviornment difference in the product with which we can run and get all excited offers for us for more click

@Alexandros81 Yes. It works well, just keep the speed low.

@Alexandros81 I have used a fountain pen on the EleksDraw, it works but isn't ideal. The results are much better with a roller ball pen or other types.

@earlfurman If you want you can send me a few examples of the turtle files. My understanding is it's very similar to a HPGL PLT file which T2Laser already loads so it would be easy to support this format.

@spareroom What software are you using? Have you tried T2Laser? (you need to reboot after using other software to free up the COM port but then it should work)

@christianlp If it isn't binding elsewhere then the problem must be the linear bearing, you can remove it from the way and see if it's repairable but don't lose the ball bearings.

@spareroom You need to configure the firmware for EleksDraw which is CoreXY and Servo mode and set the max value to 55 or less (in T2Laser this is a single click in the menu), if you didn't do these before connecting the servo it is probably damaged (cheap plastic gears get shredded almost immediately as it will over travel).

@ryan7373 T2Laser does both, drawing would be vector and engraving is raster or vector.

If you are switching between laser and servo (pen) you need to change the firmware parameters as the same output is used for both but the type of PWM signal is different. If you connect the servo while in laser mode it will over travel and can strip the gears (unless you replace the cheap servo with a metal gear version). Changing the firmware is accomplished in the Configure EleksMana menu, and setting the laser max to 55 will ensure if doesn't over travel.

I saw this many months ago, as I had the same question. Now I know. It is the mounting plate for the optional laser module. I was trying to mount the 2.5w laser module to the bearing housing for the pen module, but the holes did not line up. I am glad I did not throw this out. The aluminum laser module 'plate' mounts across this and the final assembly has a similar cross-like profile as the pen module. Now I have separate pen and laser assemblies I can trade out when needed.

@andylau

After thinking about it for a bit, I just mounted it onto the board. Although it wouldn't be the same as in the picture, its still functional (even if there is going to be more weight on the servo without the standoff screw, potentially shortening its lifespan).

Initially I thought the standoff screws acted as something more than just stoppers, but I realised that I was wrong.
