The "amps" setting is simply the limit on the maximum current and is intended to protect the motor from overcurrent during overload. More important is to get the speed and voltage correct. Usually...

Long a problem with vinyl records. Google for Zerostat guns.

Interesting problem. I assume you are machining plastic? Not something I do much of but perhaps there are known / effective countermeasures. At the machine level, I expect they would amount to adding...

Not particularly I think. Half-horsepower (375W) dc motor running at spindle speed.

The toothed belts on my Novamill have no signs of wear-induced backlash after 20 odd years. Timing belts are much easier to fit than gears too. But I agree that finer pitch ballscrew and direct...

Good gear selection would minimise the backlash and a few months of use will quite likely introduce some wear to a toothed belt system. My choice would be a finer pitch leadscrew with direct drive...

Do you mean gears? Using ballscrews the last thing you want is backlash in gears. But reduction using toothed belt would be fine. For precision better to use a bit more mechanical reduction than...

I would suggest that the first two questions are asking the same thing in a roundabout way.It comes down to how many steps per mm and a finer pitch with no gears will move the same distance as a...

do you still have theis ?

Here's section of THK's literature with a good reference of Bearing block models and bearing part numbers.

There is nothing wrong with the BK-type housing, it's the correct component for the job, it's just that the cheap ones come with crappy bearings. So just replace the bearings with angular contact...

You have a machine that's running so why not make some custom parts and beef it up!?.
Make some bearing carriers that are 1 inch thick to house 2 AC bearings back to back to replace those...

This is not all due to poor alignment.?
Because your rear plate and front plate are so long and so thin you are always going to struggle with screw alignment because has your front plate extends...

I personally would go with the pulley and htd belt as that can help stop resonance.

I also noted that you don't have all the bolts in the bearing blocks and as BeagleBrainz has pointed out the...

First off, is the undriven end of the ball screw constrained, from your photos I can not tell.

There does seem to be a large portion of the Z axis is unsupported, is there any flex/for & aft...

That looks like it's a bit more than just a NVR switch. The circuit board looks like it's got some kind of speed controller and/or soft start built in.

It doesn't matter what way the new capacitor...

Those terminals look like just two terminals with two tags on each. Look carefully at where they are rivetted into the top cap - they are probably a single piece of metal folded.

You didn't...

I'm with Clive - my first port of call would be the starting capacitor. It's not that unusual for one of these to fail and you've pretty much described the symptoms. If you can keep your fingers away...

Does the motor hum if so it could be the capacitor

G53 is working in MACHINE coordinates so it will send it to the HOME position if set to Z0. Don't confuse it with Z0 in work coordinates.

Edit: Didn't see Neale beat me to it.!..:thumsup:

The important bit I think you've missed is the G53 which switches to machine, not work, coordinates for the G00 Z0 move. So the machine should go up to highest Z, irrespective of work coordinates....

Try this for the start/end code. But just know that the first move will send the Z-axis to Z0 (or whatever value you enter for Z) for every program.

You could use the same line further down in one...

Easy if you just want to change this code just swap the lines to this.

G00 Z143.4785
A-45. F10160.

But if you want this to happen all the time then you may need to alter the post-processor,...

Is this what you are looking for https://www.youtube.com/watch?v=uMTb7uy1HfU

Yes, the VFD should be directly wired to the motor.

To switch to delta, all you need to do is spin the link bars from horizontally across the bottom three terminals, to linking pairs of terminals...
