The problem I am experiencing at the moment is that the image I’m trying to engrave on to a steel bottle is stretched.
I have attempted to change the steps per rotation on the setup menu. However, whenever I attempt to use the test in the setup menu. The machine uses both the x and y directions to move the laser head in a rectangle. And the bottle does not move at all.
The job is not urgent.
This is the rotary fixture I use
any help is greatly appreciated
Thanks
The setup process for that rotary is you need to input the roller diameter and the steps per rotation. Piburn should tell you the proper steps for your machine. Then the test button will cause the roller to make one full turn and return to the starting point. Once you have that correct you can move forward.
That reduced neck bottle will cause issues the way you have it set up. The neck is the contact point for the drive rollers and that is where movement happens. You need to turn the bottle around so the bottom is on the drive rollers for any chance of accurate sizing.
Not PiBurn or anyone else will be able to give you the correct steps/rotation. With most co2 machines of this size you need to read what the steps/rotation are on the motor driver and multiply it by the motor/drive wheel ratio.
I think it’s explained in this link.
These are digital devices and they stay digital up to the motor. If it’s not direct drive, like yours, then you induce a very minor analog change to the machines. I’m trying to say if you set it up, then the only thing that should change is the ratio of the motor to driving wheel.
The photo is very helpful, but a link to the device itself or the device make/model so we can google it is very helpful as we can see what they suggest.
The stepper motor driver has the basic settings to make the motor rotate 1 complete turn. I wouldn’t change this, just the software values. Don’t want to make it where you have to change the innards of the hardware to use the rotary.
I have two rotaries, a chuck and a PiBurn, both use different values depending on which machine I’m using, fiber or co2 both are setup using information from the motor driver.
I hope this makes sense?
If you have issues, sing out.
