[Noisebridge-discuss] lasercutter jam

[Phil Spitler]

Great, so you think think it's just a speed issue? That is EXCELLENT news.

I'll try tomorrow evening if I can get to NoiseBridge.

I hope tomorrow I don't have the connection issue and therefore be able to get cutting.

Much appreciated.

Phil
