HI, I have an atomstack S10 pro (X7) that has been working fine for some time now. but recently I had a batch of lasering that isnt as expected. I have changed nothing in the settings (makes me think its the laser) but its like its not outputting at 100% all the time.
I ran a test peice at 85% power, just a black square, worked fine one side, the other looks like 50% of it is at half power or somthing…?
has anyone else expericed this?
One thing worth considering may be excessive speed and a low acceleration setting for the size of the square.
Are you working in Inches per minute, Inches per second) or one of the metric speed units? What is your speed setting?
Have you previously lowered the Acceleration settings to work with a rotary table?
If you’ve turned off overscan and If the engraver is set to engrave quickly and accelerate slowly the laser isn’t allowed to over-shoot the edge of the square while engraving. These settings cause the laser to start engraving and acclereating (from zero). With overscan turned on, all the engraving happens at a consistent speed in the Square and the Deceleration / Acceleration happens outside the square.
If the acceleration is too low for the small square it could be spending half the pass speeding up and the other half slowing down as it engraves line-by line.
The quick way to prove this out is to redraw the square as a long thin rectangle - if the sharp transition in the middle of the engraving becomes wider that would be a pretty clear test result.
Thanks for the reply but no, I doubt its any of those things.
I’ve never used a rotary table.
The speed is very slow 180mm/min and overscanning is switched on.
Also, as noted in the OP, the front and back squares are both from the same file, no changes made in-between.
No ideas anyone…?
Some questions:
Without additional context I tend to think this is a hardware issue. Make sure the cable from controller to laser module is not loose or damaged in any way. If this occurs readily enough you may want to measure PWM voltages at the controller to make sure the signal to the laser module is correct.
If you’re absolutely certain you made no changes to the settings (*), then the problem is in the hardware or the material.
If the problem appears on the same material, then it’s in the hardware.
Which is about as much idea as I’m good for …
(*) Everyone is certain, at first, although some folks eventually admit to inadvertently changing an option they never use and, thus, never look at, only after dozens of back-and-forth messages eliminating all other possible causes.
Thanks for the reply, I use the machine for daily production runs, I’m the only person that uses it and im certain I haven’t changed aything. I kinda think its the machine, its been doing a lot of work and its only a cheap thing, maybe time for an upgrade!
I’ll keep testing a see if I find anything.
