Yepp, no lubricant. On shown settings is tool lifetime somewhere between 50-100 cutting hours. I have cut over years tens of tons alu sheets so. Maybe with emulsion it is longer, but i try avoid lubricants. Too messy

Made some rope driven blast gates. I think they are better than regular push-pull type gates.

I have here some kind of strange problem here with my new MM.
X axis gear is totally worn and gear rack looks worse than my 9 year old #38 gear racks. A and Y axis gear/racks are looking as new. All of them are from same source. Nothing does not seem to be misaligned .... Does anyone have idea what may cause it?? 2018-10-03 13.04.15.jpg 2018-10-03 13.04.31.jpg |

Wooow....can't confirm & no "metal" guru.....
But....say, in my case it was a question of how "tight" or say, how strong is the spring tension "up pulling" the motor to rack ?! Surly you have check this & fully aware of this, but, sometimes I too tend to oversee the most "obvious"... ![]() Best of luck... ![]() |

I would contact the original manufacturer, the alignment and count look good and that makes me think the gear was not properly hardened.
|

All three axis have same spring and tensioned equally. And weared is only one gear, so reason cant be over tensioned spring.
I will ask what is answers have gear/rack seller. |

|

If I had to guess and this is only speculation I think your gear did not go through a hardening process after it was machined. It became the weakest link and wore out first. You can run a file over it and see how much metal it removes compared to your other gears.
|

Ok i will try how much it is softer. But all gears what i have used on both mechmates arent hardened. On #38 is gear lifetime 2-3 years hard work.
