Hi, hope this does not sound like a rant, and if anyone has any suggestions, tips I would be grateful to hear them I currently have an A350 with the 10W laser upgrade and have been using it very successfully for the past year, engraving coasters, chopping boards etc. I thought I would treat myself to an “upgraded” machine so hence I ordered a 40W Ray with and enclosure. Machine and enclosure arrived and were duly assembled. Everything went well and both the quality of the equipment and instructions were what I had come to expect from Snapmaker. Connected up the machine to my computer and loaded the latest version of Luban I then went on to run some tests, this is when things went seriously downhill, I stupidly expected things to be similar to the A350 with a dot indicating the centre of the beam. I was presented with the red cross-hairs, assuming that the intersection of the cross-hairs was the centre on the beam. I positioned the centre of the supplied test board on the intersection of the cross-hairs and started the job only to discover that this is not the case; the intersection of the cross-hairs is offset from the beam by approximately 22mm in the X Axis and 2mm in the Y Axis. WHAT IS THE POINT OF THE CROSS-HAIRS?. This resulted in the test piece being cut partially off the test board. It is nearly impossible to engrave things in a tight space, making the main reason for buying the “upgraded” unit pointless. As mentioned previously I do engraving on wooden (Bamboo, Acadia wood, Pine, Beech etc.) boards and use 40 – 50 % of the laser power with a speed of 600mm/min, this gives me the depth and colour of image I need. I have tried numerous samples and test grids and have yet to get anything comparable in colour or depth. If I could send this unit back I would, but the returns policy makes it impossible. I cannot and will not recommend this unit to anyone until these issues have been resolved I am at my wits end and feel I have wasted nearly £1600 on something I can’t use. Any help would be much appreciated. If not up for sale she goes !!! ---

Place the 40W laser on the 350 and you have the same problem. The crosshair isn’t the exact 0 point. You can turn on the laser to place it on the right place. On the touch screen in control mode, you have on the bottom 3 buttons. The most right is Laser power. Use these, turn the laser on at 1% or less and you can place exact. Works only with the doors closed. ---

It should be relatively easy, if it does not work like this you should reach out to support: ![Screenshot_20240420_100508](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/4/b/4b0b8a9c8a81cd9cd0fea1bf64dbfcfdd7527ba0.jpeg) [https://wiki.snapmaker.com/en/snapmaker\_ray/manual/set\_xy\_work\_origin](https://wiki.snapmaker.com/en/snapmaker_ray/manual/set_xy_work_origin) [https://snapmaker.formcrafts.com/support-ticket](https://snapmaker.formcrafts.com/support-ticket) ---

Maybe in Luban. Not in all the other programs like Lightburn. ---

You have 1000%. I have Lu **ban** used 1 times and I have ban it. Not intuitive at all. Octopi with Prusaslicer for 3D printing Lightburn to laser and Deskproto to mill. Only Octopi was new for me. ---

deskproto is better than fusion? ---

[Deskproto](https://www.deskproto.com/products/language-en.php) is cam software. Fusion is a 3D cad program. ---

Hi Thanks for your response Using the Ray, how do you turn the laser dot on as there is no touch screen ? I can only get the dot when I run a boundary check, using this method it is very difficult, nearly impossible, to position the workpiece accurately. ---

Can you send codes to the Ray? The laser power is set by the S parameter. From 0 (off) to 255 (full on). Try x0 y0 S10 to place the laser at the x and Y origin with a power from 10/255. For a 40W is that 1,57W. S7 is approx 1W. ---

I think you have to calibrate the offcet directly in Merlin. Ther is an g code for programing offcet of the tools compered to pointer i just don remember wher , ---

My offset is perfect. For 40W, 10W, 1,6W and rotary. I need nothing to do to calibrate. ---
