Hi Graham, This sounds a good idea - I'd recommend adding a small amount of ammonia instead of detergent. From what I remember, even as little as 1% reduces ...
Hi Folks, Well, just got my ORAC lathe working (in the basic most ways - spindle and motor axis all work), but now I'm a bit stuck on what is essentially a...
... The easiest method is a constantly overflowing container and a z-stage to lower the component into the container incrementally. This idea was mentioned in...

As long as you know how much fluid you are adding each time, you (meaning the program, not you personally) can calculate how thick each "slice" is. As long as...
Sam..., I believe that this is only the case, if you don't meet the minimum loading requirements on the various output lines, which includes avoiding...
... each >"slice" is. As long as there are no sudden changed in cross-section >(i.e. no surfaces parallel to the surface of the milk) An interesting idea, I've...
Graham, You're spot on about the difficulty of relating the incremental volume of milk to the incremental milk surface height that results. Philosophically,...
... Lathe CAD/CAM is bit of an oddity in some respects. All that's needed in CAD usually is a half profile of the part, CAM then uses that to produce the...
The milk digitizer would have problems with convex objects. For example the inside of a coffee cup digitized from the top. Depending on your feed direction it...
Hi All, I'm assembling a PSU for my servo setup. It's a simple design: - AC input, fuse, 2-pole switch, inrush-current limiter - 1.8 kVA toroidal transformer...
When you buy quality transformers you get a load regulation figure or graph, sadly most normal transformers don’t provide this data, and the cheaper the ...
... .7 Volt/amp seems too high. That means at 20A you drop 14V!!!! There will be some IR losses in the transformer core. Do you have the inrush current...
Hi all, I have been tunning my G320 servo drive for a big Fanuc motor every thing went perfect , I can jog smoothly accelerating and decelerating to full...
... What line count encoder are you using? By dropping to a lower line count you will fault at a greater following error. It will cost you resolution but with...
One other thing you might try is to lower the acceleration rate. Dan Mauch economical 3D scanner software and kits low cost stepper and servo motors. cases for...
... Hmm, this seems strange. Now, the DC may droop a bit from no load to small load, and then level off. Leakage inductance may cause the no-load voltage to...
Hi all, I'am using 400 line count encoder lowering might help. But Dan lowering acceleration rate won't help when sudden stop from full speed. Shadi ... ...
Shadi, If any system does a sudden stop from high speed, it will lose position. Motor size is irrelevant. It's inertia. The motor must ramp down as commanded...
I have done the same as u. Controlling big fanuc servo with G320. Try this, it might help: 1. reduce the acceleration. 2. reduce the max speed. 3. Try to...

Jon, Oh sure I understand that. The encoder board I sell tracks the encoder at the control software as well. Although, it ONLY tracks position and Estops if a...
