Hi
Im new to this so be gentle with me.
I upgraded to the 1.3.01 and started my job but half way through on the start of the line cut it went of point and started cutting across the same area so I stopped the job and there was an awful grinding sound on my Y-axis and it wouldn’t work anymore it was grinding and the control panel read the home instead of 0.00 on each it said 10000.0 on all axis points on the control panel.
After a few days of trying to restart and shut down my laser its an omtech 80w laser using Mac O.S. it was just grinding all the time I went everywhere trying to figure out what happened I had not changed any settings in the software all I did was upgrade.
So I downgraded to 1.2.04 software and its been working fine for the last 6 days no issues and the home where they should be 0.00.
I have just started a new job on it after finishing one and its at it again in the start of the new job it was just going over and over the same area and this time its the X-axis that is grinding. Again I haven’t changed any settings and the control panel reads my home as 10000.0 across the X,Y and U
Is anyone else having issue since upgrading ? or downgrading ?
Hi
Thanks for the reply. I moved the laser to the centre of the bed then powered it up. It is trying to hone to the top right but I have to stop it because the y-axis is grinding and won’t move up.
Using the control panel on the Rudia I can move it left and right on the x-axis no problem. But if I get to move it up and down it’s making an awful grinding noise and barely moves.
I’m worried about snapping my belts so I have to press the stop button if it attempts to home.
Thanks
The motors don’t have anywhere near that much torque! Steppers make a horrible sound when they can’t produce enough torque, but it’s harmless.
With the power off, move the gantry by hand from front to back a few times while noticing what happens:
It should move smoothly without much effort and no abrupt sticky spots.
There should be no odd sounds at any point, particularly when reversing directions.
If it doesn’t move smoothly or you hear (or feel) anything odd, figure out what’s causing the problem. It could be an accumulation of crud in the linear slide rails, a chunk of debris caught in the belt, or a loose fitting in all the shafts & pulleys between the motor and the belt.
With the power on, use LightBurn to examine the speed and acceleration for the Y axis. There is no reason for those values to change without notice, but it’s worth checking. They should be close to these:
I disagree with @ednisley here, don’t mess with the configuration until there is good reason to suspect it, which we have none… this may introduce other issues. If it’s changing on it’s own the controller is broken.
It is a good time to save it, if you haven’t already.
Your having issues with the Y axes and the diagnostic panel shows that home switch to be active.
Can you ensure that Y limit switch is working or ? Most of the times this is not active … wondering if you have a home switch issue.
Hi,
Yes with the power off I can move the gantry back and forth and up and down without any issues. When the machine is powered on and it starts in the middle of the bed it attempts to go to the home position. But because the Y-axis is not working and it’s grinding it is like the laser is saying it has no more bed space left and it has no where to go so it grinds.
This laser is about 6 weeks old and I do fully maintain it and clean it too.
Ive placed a metal object over the Y-axis and it is lighting up fine, I have also checked the side panel too and that is in good working order with the lights.
Is there a way to reset the control panel on the laser to its original settings when it was shipped out to me ?
It was all working fine yesterday and previous days before that. I had problems with the X-axis when using the newer LightBurn software 1.3.01 after I installed that a few weeks ago. So I downgraded to 1.2.04 and I got my x-axis working again.
Now after doing half a dozen jobs in the last 6 or 7 days I now have the Y-axis grinding and refusing to go home.
I powered off and moved the gantry to the top right where it would normally home. The controller reads the image I uploaded before that the X,Y and Z are at 10000.0 when they should all be reading 0.00 that is the only significant change that I see has happened. But I haven’t been in or changed a single thing on it.
It is a little bewildering why it would be working fine and then it just decides to start grinding!
But thank you for trying to help me, I really appreciate it.
If you save your machine setting, you can do a factor reset and restore the saved machine configuration. I doubt this will buy you much.
You can reset it, via a power up or the panel ‘reset’ button, but it will retain it’s vendor configuration information.
The Ruida is a general cnc controller and the factory settings don’t include those set by your vendor.
Generally a factory reset makes the machine unusable as it’s missing the actual vendor information.
I think you need to look at what’s happening as it boots and what kind of control you have when you have to ‘esc’ out of it. Until it will ‘home’ properly, it will not be of much use, so I’d start there… as I’ve mentioned before.
Actually it should still work, but the coordinate system will be skewed to elsewhere. You should have x and y controls.
Did you check the motor drivers for errors (red led is hardware)?
If you want to modify the controller, have at it… It hasn’t been show to be an issue and I don’t want you to possibly add another problem to the one you already have.
Was the Y axes on it’s ‘home’ switch (active) when you photographed the diagnostic panel? When you trigger the Y home, does it show up on the controller AND on the Ruida controllers console as active. Does it show ‘inactive’ when the switch isn’t being triggered?
However, in recent days we’ve seen enough weird cases to at least want to know those settings remain valid. From what I can see, they’re just fine, so there’s no need to mess with the controller.
It looks like the directional control to that axes is not changing.
If you move the gantry to the front or middle of the machine, does it only move towards the rear?
I’m trying to figure out if towards the rear is the only way it will move with the console.
If it only moves towards the rear, there is a signal to your motor controllers that specify the direction of travel.
A picture of the Y motor driver would be good… nice photo of the X driver, but that’s not the issue… Been nice to see them both.
I’d suggest you ‘gently’ tug on the wires where the ‘dir’ input is and also on the Ruida, the source of the direction signal. Sometimes these are held only by glue, didn’t get screwed down… Make sure the connectors are seated…
Don’t change anything, just check… your motor driver may have a different pinout… they have a placard on one side, like this…
Have I missed mention of making sure the belts are not too tight? And yes, if the Y axis belt(s) were too tight that could wear the motor bearings to the point of being too much to move the axis.
You can try to loosen the Y axis belt and see what happens when you try to move in Y or even remove the Y axis belt and see if the motor moves smoothly without dragging the X axis along.
I suppose the Y axis driver could have failed also…
