Hi , watched your video of setting up z axis , i have a major problem of when i ask to cut any mm laser head makes a horrible noise, it frames fine and works well in other commands except for cutting and engraving , any advice would be greatly appreciated Cheers Nicole
If you are putting in a thickness that is normally for a different type of laser. One that as the height set to the bed. You should focus the laser on your material. If you want to lower for cutting, you have about 6mm you can lower before hitting the material.
Hi I have recently bought a TwoTrees TS2 and was having difficulty in understanding how to set the z axis untill see your video. Great video, very well presented and thank you for sharing.
I'm finding that when I use autofocus for cutting, it leaves the probe right on top of the material. Which then drags along.. if there's any imperfections, it sticks into the material. Almost feels like thee should be an extra height offset. In your example (2mm cut), the probe comes quite a way back up.. I don't know why mine is different... I'm using the official settings. (TS2 20W)
There is something wrong with your setting. If the probe is dragging it is to low. I believe the offset for engraving is 7mm. You can then change the micros to a max of -6mm. If you you set it any more than that the probe will drag.
Just found this video. I have the same problem with my TS2 - I also have the 20W laser which is slightly different than the 10W in this video.... I also (think) I'm using official settings. I'm wondering if it's mounted correctly. It seems like focus is right for cutting/engraving; it works as long as the probe doesn't bind too much. I may have to go get my calipers and measure carefully...
Ok - here are my results in case it helps the next person who finds this. With the "official" settings this machine with the 20W module homes the Z-axis with slightly less that 3mm between laser housing and surface. My ramp test says this is too close - should be more like 5mm minimum (which is also what is printed on the 20W laser as a focal length). The laser is quite good and also will cut at a greater length as well. The probe itself (which is mounted directly on the Z axis and not on the laser housing) hangs between 1-2 mm below the housing and has a bit more than 1 mm of play before it hits the homing switch. So given all this it is not at all surprising that the homing probe hits the surface - especially when cutting. I think I'm going to ditch the probe (so it doesn't hit and interrupt my cuts with "hard limit reached" errors), manually home Z at about 5-6mm and move on. Sorry TwoTrees.... good idea but not well executed; a well designed probe would need to "get out of the way" like many of the 3D FDM printer autolevelers do. Another option I considered is shimming the probe so it has less play in it but that only gets a 1mm more of safety and seems fiddly.
The Z axis does not move very far or often. I have never needed to adjust its speed. Most likely, the speed is controlled in the firmware. If you are using Lightburn, you should be able to adjust it under device settings. Scroll down and click on the header. Once you do, you will get a warning, and then the firmware settings will open. I would take a screenshot, so if you start having issues, you can undo the changes you made.
Is it moving slowly while engraving or when homing? $112 should give you your firmware max speed. What speed do you want to run? I have given away this machine, so I can't pull the factory settings. Typically, you set the max speed under machine settings. If you want to speed it up while manually moving, the speed can be changed in the "move" window.

I am glad it helped.

Hi man, my z axis moves so slow . How can i speed it up ?

@@ShopRamblings ok but, do you know exactly what change should i do in the software settings?
