Hi, I just bought a Gweike Cloud RF laser, I’m’ learning how to use it with LightBurn, everything works fine, but I just have this problem with the rotary:
I place the laser at the desired position, select the option Star From = Current Position and select Job Origin to center, I play but the red light appears immediately and it doesn’t start.
Whereas if I select Job Origin = Top Right, it works correctly. Is this really a laser problem or am I doing something wrong ?
Can anyone be able to help me ?
If you set your job origin to the top right, the job will engrave down and to the left of where you are. If you select bottom right, it will engrave up and to the left…
You are driving your machine out of bounds is what give you the error. It would be nice if those had a control panel… It would tell you …
Is there a way to set a user origin on that machine?
thank you for your interest in my problem.
I will tell you the problem I need to solve:
I have a can of coke where I need to engrave a name in the center of the can in a certain position.
If I use absolute position, the inscription is printed in the center only the can turns 180° in makes me the name on the opposite side.
If I put current position with job origin = top left the print is correct only I can’t keep it in the center of the point. I should use the job origin = center, but that gives me the machine to go in error. Only the center because the others work correctly.
I looked, but I didn’t find anything that makes me set user origin.
Can you lase this on the table without issue?
I’m not familure with your machine…
What is the setup process to use the rotary?
Do you reset the machine, then switch it to the rotary or ?
What corner does the machine home?
When you press ‘test’ in the Lightburn GUI setup for the rotary, does it make one complete turn and return? Which way does the to be lased surface of the mug rotate, towards you or away from you?
“Can you lase this on the table without issue?”
The machine works properly on the floor.
“What is the setup process to use the rotary?”
I connect the rotaty to the appropriate connector, raise the left switch to rotay and turn on the machine .
“What corner does the machine home?”
The car has homing in the upper right corner
“Do you reset the machine, then switch it to the rotary or ?”
What do you mean by “Do you reset the machine, then switch it to the rotary or ?” once the rotary is mounted with the car off, I turn it on and then I don’t have to do anything else.
“When you press ‘test’ in the Lightburn GUI setup for the rotary, does it make one complete turn and return? Which way does the to be lased surface of the mug rotate, towards you or away from you”
Yes if press ‘test’ in the Lightburn GUI setup for the rotary, it make one complete turn and return.
It rotate toward me, but not enable the rotary in lightburn, this machine working without this option.
My goal is to be able to print a name in the center of the black dot, I have to print several names and they always have to be there in the center.
If you’re in Lightburn, can you go to the move tab in the cut/layer window and get the current location…?
Usually when the machine boots, it will home. Yours apparently works a little different… ?
I’m trying to determine where your machine thinks it is. That might help us figure out what the issue is.
I’m used to having a machine console…
I live in italy and hours are 2 am I can’t turn it on now because it makes a little too much noise, today around 2PM I will turn it on and let you know.
You do realize to test this you only need the controller/motors power on? You don’t need the laser to fire or a chiller running…
1)This is my machine, you can’t turn on only part of it, when you turn it on it starts all together and the fans make a lot of noise, I don’t have coolers or other kinds of external things connected it’s all one.
2)This is the rotary connected, the switches for lightburn must be in this position otherwise it doesn’t work, I placed the X-axis at the point indicated 1 (because I am using rotary number 1)
3)This is the initial position, as you note it marks everything to 0 because I am at Home
4)I insert the lettering in the center of the black point I had marked, place Job origin = center and position the laser in the center of the black point by moving the x-axis
5)I press play, the machine turns on the intake fan as if it had started but the red button immediately appears and does nothing. At this point instead of pressing the stop button I press the pause button, the machine magically starts but only prints half the writing.
I cannot understand all this mystery.
It would seem that lightburn at first sends some command that angers the machine, but then however the rest works. I tried repressing play instead of pause but it does nothing.
Thanks for the extensive setup… I will have to think about it a bit to give you some kind of suggestion. It still sounds like it’s going out of bounds…
Hang in there…
I also sent a video to the manufacturer, so let’s see if he can tell me anything about it.
I will keep you informed.
Yeahhhh IT WORKS !!!
Your off-axis theory was correct. I understood why, when I positioned the laser, the Y axis was set to 0 not accepting the negatives, it could not go back to do the rest of the writing and went off axis causing the machine to go into error. to avoid if the machine has to go back and forth on the y axis, I position the y axis in the middle of its scale y= 145 which is that of the complete rotation of the rotary in my case y=290. This way everything works perfectly.
Thank you very much for your help which has helped me to think about the out of scale.
Great, I’m glad you are up and running…
The concept is simple, but the actual application can be a mind twister…
If it’s all good, mark the post that answered the question solved… your previous post pointed out the solution, so that will work also…
Take care and have fun
OK…many thanks and greetings from italy
