'Need Source for Mach 3 Based Sherline CNC System'

GerryV from Canada (Contact Member) -

Hello, This is my first post to this forum.

I am looking to source a Sherline 6200-10 CNC Ready Ultimate Machine Shop Package plus some additional accessories. My decision is to go with Mach3 plus its upgraded wizards and possibly related hardware/plugins such as the SmoothStepper or NCPod. My goal is to have a very dependable and accurate setup, not necessarily the most leading (bleeding) edge. I have a few questions.

1. Can anyone recommend a reputable, established system supplier(s) who can sell me a complete, turn-key system without trying to switch me to their own or some other control software?

2. I'm considering switching the lead screws to Kerk lead screws (not ball screws) and anti-backlash nuts. Has anyone actually done this? Was it worth it and in what ways?

3. I'm considering bolting the mill and lathe onto marble flat surfaces to maximize rigidity and accuracy. Again, has anyone done this and was it worth it?

4. I'm wondering what the most suitable size of stepper motor is. I'm looking for good (but not crazy) speed and want to minimize the possibility of lost steps. Also, good quality. Vexta seem to be the best. Does anyone have experience with these on a Sherline setup? Are there other highly rated ones, perhaps Rex?

5. Can a BIG controller be used to safely drive these small systems? If I can't find a supplier for a complete, turn-key setup, I'm impressed with the Novakon SmartDrive which comes with the computer built into the box and the full, licensed version of Mach 3 preloaded. It comes with four Gecko 203's and (here's the key question) provides up to 75 volts to each motor. I simply don't know enough about electricity and electronics to know whether this would turn Sherline machines into spaghetti or not. Can someone with expertise in this field provide some guidance in lay terms on this question?

6. While I do want to be careful about spending, I'm not looking to save a few bucks here and there by cutting corners, building the system myself, going with the lowest cost steppers, drivers, connectors, etc. but, that said, I also want to get quotes because I'm aware that a number of suppliers offer sizable discounts, especially if they are providing complete, turn-key packages.

Thanks kindly in advance for your advise,

GerryV

Is this actually a forum or just a fraudulent means of gathering email addresses?
