My rabbit is the same model with a different name, My machine skips on anything over 2, and 8.
Figured those were the max settings anyway...?????

Actually that was an old post, but yes I have the same machine and 2 for cut / 8 for scan are about the max numbers - I can push 10 for scan ok and 12 just works but sometimes skips a few steps depending where on the machine.

I live in Ecuador. I bougth this macine in internet.
I don´t know how to calibrate the laser for diferents materials. Some times the cut line is very thick.
Sometimes the laser is moving too that the drawings are distorted.

Please help me
Thanks

If you are cutting, the speed should be set at 1 or 2 max.

For engraving (scan) you can use 1 to 12, with 8-12 being usual.

Of course you must also adjust the power for different materials also.

What materials are you using, and for cut or engraving?

I use leather, rubber, glass, cork for engraving.
For cutting I use paper, raft, cork, acrylic.

Where can I adjust the power? because only can adjust the scan speed and cut spped .

Which means Cut delay , scan delay and gap delay????

[zax15uk]

Power is adjusted on the machine, using the 'Current Regulator' knob. If you turn it fully counter-clockwise the power will be 0, each turn clockwise would be 10% of the power.

The delay settings allow time for the beam to turn on before the machine moves. Defaults of 1ms should be ok.

Line gap is used when engraving to set the DPI. A setting of 0.05mm is 508dpi (25.4 / scan gap = DPI).

Cork is very difficult to cut, it absorbs heat too well and burns. You can burn an image onto it but it will smudge unless you seal it.
