Hi Zak,

I took the machine apart yesterday and the left hand extrusion was a bit rough along the rails. So I went over with a bit of wire wool. I also put the belt fastnersI found on thingiverse at https://www.thingiverse.com/thing:2564431
These helped me tighten the belts again with the same tension each side.
All is now working great and I am getting some really good engraving results.
Thanks for the help.

Thanks Zak,

I intend to take it apart and ensure the rails are clear of any pits or divits. I also have another belt from my 3D printer so I will also change the belt as well as use the 3d printed belt tensions to see if that works. I will report back.

Hi, sorry if noob question, but I have just got into Laser etching.

I have put the machine together easily enough but the Y Axis isn't moving in parallel. The left hand side moves a little more than the right. So I was hoping someone could help me sort this out.

Thanks in anticipation.
Mark.

Hi Dave,

I had the same question myself. The extra circuit board allows you to plug in the power supply directly to the laser. Not sure why you would want to but that's whats it's for.
