@foxylad@Zax Thank you for clarifying! I have bought an EleksMaker A3 5500 mW from GearBest, but they have not confirmed that they ship the new laser. I see that BangGood does. Do you recommend cancelling from GearBest before they ship and just buy from BangGood to be sure to get the latest version?
@joelrsails personally T2 is versatile enough for everything I can think to do with a laser. You can also try bencut laser which is made for cutting. The only advantage is you can give each cut its own speed/power so you can do slower against the grain. This means you are limited to dxf files and it cant engrave.
FYI. BenCutLaser does now do image engraving (with version 2 out). I know nottingham82 knows this, but figure all you should know too.
@JürgenH. If you are happy there is no friction, everything runs smooth then adjust the belts and test it. If you see the same problem I would suggest to check the motor current (you will need a volt meter).
@mutton44 Most embarrassingly, I confess to having this problem, after playing with the X-axis tension for three days, turning off bi-directional cutting, I bumped the laser mount with my wrist while aligning a small board and it wiggled; the thumb screws holding the laser module onto the carriage mount had worked loose, and the module would lean slightly on right to left movement. I tightened them, reset the tension on the belt, and now works great.
