I've noticed something rather odd with my X carriage (the thing that you attach a laser to), and I could use some advice.
Long story short, the X carriage requires a very significant amount of force to glide along the X-axis rail.
It's so tight that it tends to stall the stepper motor when I start engraving. Only stalls briefly, but I'm sure that's not supposed to happen.
I've actually had the laser for about a year and haven't been using it due to the ventillation issues,
this problem and a really bad experience with EleksCAM (constant errors and crashing), but I'd like to change that.
I've attached 2 videos that should hopefully illustrate the problem, the Y-axis movement seems to be just fine, but X-axis
definitely struggles. Force required to move the carriage also seems to vary depending on the location on the rail.
In the first video, I've used a cheap, portable scale as a way of measuring the resistance. I figured it can give some insight.
In the second video, you'll notice how the carriage seems to snap in place. At the places where it snaps, the resistance is greater.

Upon visual inspection, I didn't notice any visible abnormalities such as burrs and alike. I've also tried to put a rail against
a flat board and shine the light behind it, then seeing if I can see the light under the rail (to measure if it's straight).
The rail seems to be within acceptable ranges, visible light was next to none, telling me the rail is pretty straight.
Next thing that comes in mind would be the belt tension, but the belt is actually very loose. Too loose
in-fact, but that's not important right now. Point being, the belt isn't causing the carriage issue.
I've also tried to tinker with the wheels, but the issue seems to remain even when they're loosened.
This makes me think that the screw holes on the acrylic plate aren't well positioned / are too close to the rail.
I don't know if anyone experienced a similar issue, but I could really use some help.
1.Spacers on the axle shafts are the same length.
2.Bearings are spinning freely.
3.All wheels have the same diameter.
