Machinist in X-50

Hey Bill, hey all,

@Machinist

Your line of thinking is spot-on in questioning why the router is inserted all the way down into the holder. If it could be held closer to the bottom, that would help tremendously in making things more rigid. But as you also commented, it would reduce Z travel by the amount you raise it up.

But there are at least some attempts of solutions for this. The one would be the 80 mm mount which lets the milling motor clear the stepper, and the other would be moving the stepper coupler cage upwards as I remembered myself here, using these taller stepper mounting blocks and extending stepper axle with another coupler. Either of the two solutions would remove the restriction on Z travel and on vertical motor positioning in the mount.

I don’t exactly know what your needs are when you work with the machine, but you are very familiar with what the limits of the construction are the way it is at the moment. Did you ever consider one of these solutions for you?

@Machinist

Ball screws & linear bearings are great for accuracy, but they aren’t the first choice for a vibration-induced load like you would see when machining steel.

Would you say that when it comes to withstanding vibrations, toothed belt drives are better positioned?
