The UC400ETh requires a 12V-24V supply, not a 5V supply.

Looks sensible to me.



This is just setting the microstepping factor - it doesn't really matter which you select, they'll all fundamentally work, but the higher the setting the smoother your...

Hi There,

Nice looking box and work - Some ideas

1.) Fans - Try not have the fans on the same surface as the air will just go in and out across that surface you would want the air to go across...

I was talking to a guy who does control electronics for a living and he suggested twisted pair on all data cables inside an enclosure as a better option to shielded.
Logical when you think about it...

assuming you are using mach 3

I expect in ports and pins you have

X axis step = pin 2 , direction= pin 3

Y axis step = pin 4, direction = pin 5

Z axis step= pin 6 , direction= pin 7

To some, this comment may seem little condescending coming from a bunch of electrical geeks just trying to show off.!! However, A_Camera is making a very valid point because Terminology is very...

Yes, it does. Any voltage, from 12V through 24V DC, according to the manual, and with a current rating between 500mA and 250mA (Multiply the voltage and the current to get the power requirement, e.g....

Looking at the UC400ETH manual, and having examined my UC300ETH/5LPT closely, I'm going to suggest the following:-

Background info: The UC400ETH has a small DC-DC convertor to take the incoming...

If your BoB is POWERED by USB (caps, to emphasise that the BoB is only powered by USB, but signalling is still by parallel)...

Keep it simple. Use the power switch to power the stepper drivers. If...

1) EMC filter. Helps stop noise escaping from the control box into the mains supply, and also stops noise coming into the control box from the mains.
2) It's a bit tight, but I've see far tighter....

Good. At least we know that the mechanics are OK. Now change the pulse width to 10. If that doesn't help KEEP it there and change speed to something really low, like 500. If that is still an issue...

Just checked, and I should of said get TB6600 drivers if you do replace them.
TB6560 is the older chip, whereas the TB6600 is newer, far more resilient, and has better performance.

Which has also...

Going by the picture, K1 and K2 set the microsteps.
K3 and K4 set standby current.
And the SW set motor current.

If the new computer has made no difference, then that should rule that out.
...

Ok, so you have 5mm ball screws.

Now the Sw1 SW2 SW3 set the current range for the drives which must match or be just less than the motors rating. This setting can be set above the motors rating...

Suggest you take step back from messing and changing settings etc until you know 100% what you have. Just because the box looks the same doesn't mean whats inside is the same. These chinese things...

~It looks like that board has the facilities to control the spindle with Mach3, but they are not wired in. at the bottom right on pic 4, the board is marked C (Com) NO, which is a spindle relay...

One of the key fountains is right here in a sticky thread on stepper motors. Don't try and understand the maths, just use the spreadsheet. In particular note the corner speed at which the motors...

Hi have you tried my mach 3 set-up here

The high pitched noise is the motor stalling.

Stepper motors rely on their windings being energised in order. If you overload the motor mechanically, rather than the motor spinning smoothly, it...

Try a Google search for "mach3 settings explained". There are plenty of sources of info there, and different people prefer different ways of explaining things, so take a browse through what's on...

I'm guessing from the Mach3 settings that you have 5mm lead ballscrews with 8x microstepping in the stepper drivers. That explains the "320 steps per unit" in the motor tuning page. That's about...

If it's a serial port on the PC it will have visible pins (male), parallel ports on the PC have holes (female) ;-)

As Magicniner says - and the plugin needed for Mach3 is probably the "USB connector software" you mention. Can you list what is on the CD/memory stick/whatever? It's very likely that you have...
