Since your configuration is all messed up, you need to go into machine settings, all the way down to the vendor settings section. There you input the correct ‘Max Travel’ for each of your axes. These are the settings for my machine. I’m sure yours is different.
Seems like you have more or less the same settings as I do, with a few exceptions. I’ll try to find how to calibrate the axis. Thanks!
You can save what you have and maybe @thelmuth can give you a copy from his machine. Might be closer.. if not you can reload the saved version and put you back to where you are. It can be quick.
No problem, I’m still in NY and won’t be home until Monday.
I’ll try that! I also tried to calibrate the machine axis, it got better but still hard to get the exact measurements with the dull tools I’ve got in the shop. I need more precise stuff, which I’ll get 
To have another backup file from a machine similar to the one I have would be amazing. My machine is 700x500 (X/Y) and 80W (if that matters). Many thanks!
Just an update on this, I actually think this is fixed now. Wouldn’t have come anywhere near a result without all your help. So thank you!
Though, issues tend to come in pair. Now my new laser tube is acting all weak. I’ve aligned this as per all instructions but even with 70% on both max- and min power it won’t cut through a piece of thin leather, which it did easily with my previous laser tube.
Any clues where I can read more? I’ve found a million threads but not any luck yet. Thanks!!!
If you have a knob for power on the console, it should be all the way right. This will limit current to the tube.
If you have
They just work.
With new machines, alignment is not something you generally just do. Proper alignment isn’t something that occurs simply. You have to do it many times to get used to how it’s done.
I’m guessing you’re thinking it’s properly aligned.
This is the problem most of the time it’s not really aligned.
If you need to, start at m1 and check the tubes resonance or TEM mode.
No matter which of the three points is faulty, it’s not going to work correctly.
Have you, perhaps inadvertently, switched speed units from mm/s to mm/min or inch/s to inch/min or something along those lines?
If the layer speed is lowers than the controller’s Start Speed, it will reduce the power dramatically. In principle, it should not go below the layer’s Min power setting, but …
The controller also has minimum and maximum power limits for the laser tube. Both of those will interact with the LightBurn laser power level, although it’s not clear if they are hard limits or apply scaling factors. In any event, make sure they’re not set to anything absurd.
Thanks for the reply. I tried to shift form mm/sec to mm/min and that didn’t make it better, but worse and totally out of time from my previous cuts. I actually started a new thread to keep the topics separated.
Many thanks!
