That board should still work, you just need to use the right firmware.

@dave_nh I will mention, if you ignore the errors (as a lot of software seems to do, including Eleks own) you run the risk that Grbl crashes and leaves the laser on while the motors are stopped = fire risk!

@inhousespy

you need to elevate the piece and then run multiple passes

@alius2010 It is a mechanical issue called backlash. T2Laser defaults are more aggressive (although still very reasonable), if you disable bi-directional or enable reduced acceleration you will see it goes away. These are band-aids for the real problem, your belts and/or gantry wheels need adjustment.

With smaller jobs and higher detail the carriage (laser head) doesn't have time to catch up with the motors as the belts stretch.

Thank you.

@MrMG Have you tried a different cable and/or USB port?

If that fails the boot loader may have been corrupted, you would need to use the Arduino IDE and another device (or programmer) to flash it.

@bobselektrabus I highly doubt there is an actual manual. The software gets updated so often that any manual you would find would be out of date.
Best way is to post here with your questions and let the community help you out.

If this is supposed to be an official after sales service area why is no one from Eleksmaker responding. I'm starting to regret buying the plotter. Banggood havent replied to my email either. I paid with Paypal so it looks like I'm going to have to ask Paypal for a refund. Will return the plotter but I will refuse to pay the postage cost because this is not my mistake. Returning the plotter can still be avoided if Banggood or Eleksmaker agree to send me the metal parts I need. But I'm not going to wait much longer for someone to reply to me.
