  2. Re: double rack on single pinion to remove backlash?

    Thanks ! I had a brain fart.....it was late here in Germany when I posted this question. The DamenCNC double pinion solution while interesting is not as robust as I would like. The belt inside...
  3. double rack on single pinion to remove backlash?

    Imagine having two pinions riding on two side by side racks. You tighten down the inside rack and leave the outside rack slightly loose. Push the gantry on one side (with the power to the motor on...

    Re: Servo motors upgrade

    If you are using a HyperTherm plasma on a commercial table have you contacted HyperTherm and talked to them about a control? Would not be the cheapest route but for sure would be the best route.

    Re: Gantry design?

    Gantry design?

    I am building a 3x2.5 meter router. I am curious as to what you all think the merits of either a Mechmate style gantry versus a vertical type gantry would be. The machine will be used mostly with...
  11. Re: Best belt drive ever! (If I do say so myself)

    I personally think that would not be an improvement. If the lower belt wears enough that you need to change it out that would take 20 minutes. If the aluminum wears out how long will it take to...

    Are you aware that Centroid actually dropped the price of the Acorn recently? Not because it wasn't/isn't selling. It is selling extremely well. I look at it this way. If someone is starting out...
