Measurement issue

Noticed my measurements weren’t correct after cutting.

Tried using the calibrate axis form multiple times but nothing would change.

Looked in machine settings and noticed the rotary was green “true” so I turned it off. Which did nothing other than make my laser head super slow and make the y axis even smaller when I framed it.

Not sure what the heck is going on. Any help would be greatly appreciated!

I attached a picture of my machine setting screen before I turned it off.

Are you having this issue on a rotary?

What type of chuck are you using?

:smile_cat:

I’m not trying to use my rotary right now. I’m trying to do flat work. For some reason the rotary keeps getting turned on somehow. Both in the machine settings menu and under tools where the rotary set up is. The rotary I have is from HM laser accessories.

Turn the rotary off… that’s probably your problem…

Use Laser Tools → Rotary Setup and turn it off there…

:smile_cat:

I tried that. It is supposed to be a 3x2 rectangle and with the rotary on it cuts out as 3 x 2.51. When rotary is turned off it is 3 x .18 and the laser head goes extremely slow.

Did you change anything when you used the rotary? Is there some type of configuration file that you use when the rotary is enabled?

Nothing should change, configuration wise between the two, unless you change something.

@berainlb can probably assist on this… I’m not a real grbl master and especially not with the xTool.

Hang in there…

Not that I’m aware of. I don’t laser very often. I have an Omtech.

The only thing I remember having issues with during the rotary was a frame slop error.

Sorry, for some reason I thought you had an xTool… hope I didn’t answer them thinking it was you… :exploding_head:

You calibrated the axes… what did it change? If nothing changed, something is wrong…

:smile_cat:

Nothing changed at all🤦🏼‍♀️

Here is a Thunder laser video that’s <3 minutes… see if the procedure you followed is the same…

I picked the shortest one I could find.

:smile_cat:

Yeah I watched that one and a few others before I tried it. I followed the same steps and nothing changed.

Excuse me while I pull my hair out :woman_facepalming:t3:

I’ve never had these issues, so I’m not the best source…


When you go through the procedure, does all the steps work as stated?

Where does it go astray?


Getting close to my bedtime… so don’t know how long I’ll be around…


Don’t get frustrated… it’s a machine and we’ll help you figure it out…

A word of warning… don’t work on it when frustrated… it never ends well…

:smile_cat:

I don’t get any error messages or anything. It acts like it works but I try to cut something out and nothing had changed so I’m not sure what I could be doing wrong as far as that goes.

I appreciate you taking the time to comment back.

We’d all like you to be up and having fun, not frustrated…

So… I got frustrated and restored my LightBurn to factory settings and had to re-add my machine. X axis works perfectly from controller and y axis is making all kinds of noise. When machine gets turned on, it’s also making the noise and not homing correctly. I will try to post videos for reference.

Trying to move y axis with controller

I assume this did work OK on the Y axes? So it would have to be a Ruida setting.

That is usually the fields moving faster than the mechanics can respond…

Keep a version of this somewhere and check to see what the stepper motors are set in the Ruida…

You’ll probably find a difference between the working X axes and the noisy Y axes…

In all likelihood they are probably the same motors and drivers. Probably the same diameter of the pulley also… So I’d expect them to be the same or very close to it.

I uploaded new lightburn settings and I tried moving the laser head to see if it changed anything aaaaaaand now I have 0 power to my controller :joy::woman_facepalming:t3::cry: the power switches light up and I can hear the fan but can’t do anything with laser

Fixed the power issue, had a lose wire that came apart when the laser head pulled too far forward when I turned the machine on and it’s improperly trying to home.
