Thanks, Mountaindew. Are you using F360 for CAM? Does the 15L post processor work? Got any feed/speed advice? I plan to build tool libraries for aluminum, brass, and steel and CAM templates for...

I just got the final pieces of mine and put it together this past weekend. Tidy little package. Haven't spent enough time on it to offer much in the way of a review, but it seems like a good machine...

Any progress to report? My interest in a CNC lathe for hobby work took me down the exact same path re: gang tooling. Most of the effort is already undertaken in CNC'ing the cross slide. I'm surprised...

Devil's advocate question: What is the benefit of the bottom belt? Seems to me it would all work with just the belt that's wrapped around the pinion via the idlers.

What sort of reduction are you using? I'm surprised you're only getting 100IPM if you're at 1:1.

1425 RPM / 5 TPI ballscrews = 285 IPM. So you're probably using some sort of reduction, or are...

Mariss:

Another vote for you to continue sharing your servo sizing wisdom.

Very interesting product. I'm fixing a broken Bridgeport clone retrofit that has a 115VDC power supply. The old drives are shot, so I was thinking of trashing everything and setting up a 80V...

Two questions:

1) Why did you go with the E winding on the Magmotor? Looks like for 81V, the C winding may have been more efficient (albeit at increased RPM).

2) Which US Digital encoder is...

I've just taken delivery of a full sized knee-mill (a Sharp bridgeport clone with 3hp/4500 max RPM vari-speed head). It was converted to 2-axis CNC over a decade ago, but the controls are dead. So,...

I plan on using NEMA 34 850 oz-in servos factory rated at 72V.


I was hoping to run the G320s off of a 5V from the G100. Is this not possible?


Was hoping to power the limit switches from the...

One quick question on the current schematic: you have a few ovals drawn around groups of wires. Is this meant to represent the grounding of shielding? I couldn't really figure it out. Did you find a...

Yeah, what Bob said! This thread is actually the only place I've found useful information on wiring up a G100 (I'm several months behind you guys, but plan to retrofit a knee mill with G340s & a G100...

Hi there:

I've got my eye on a 1.5KVA transformer at 52Vac and 12Vac. Rectified to DC, I should get 72V @ 20A on one secondary and 17V @ 4A on the other.

The larger secondary is getting close...
