Why didn't I thought of that ! Now I need an extra big lamp to put in there!
Thanks guys you are all so kind!
I am thinking to place the emergency stop at the bottom right ,since there is the right hole for the switch and scrape the e- stop letters from the bottom left hole?
Maybe I can put another switch on the bottom left hole in the future a button that I can not think of now.
For sure I can print new letters or marking on the panel....

Small progress.
I 3D print the lower panel for the motor connectors no big deal but I like how the front panel looks now...

Hi Nick,

Looking good, keep it up!

I am using the uc300eth UB1 with AM882 Leadshine stepper motor drive, as I understand from the Leadshine manual I have to use 2k resistors for the PUL- , DIR-,ENA- and alarm since I use 24volt outputs of UC300 eth ub1 right?
Can someone explain why the resistors are connected to - lines? Is that safe for the drivers? I have seen some diagrams connecting resistors at the + lines for protecting the drivers but this is the first time that I see the opposite.

All the resistor does is limit the current to about 12 to 15mA at 24V going through the led

**Nickhofen** · 11-07-2021

So is it safe to use only one resistor per driver, at EN+ as the diagram above?

The MOTOR OUTPUTS are 5V not 24V, only the general OUTPUTS are 24V, so you don't need the resistors for the drives.

**Nickhofen** · 11-07-2021

So I am going to use 2k resistors as shown on the diagram below, right?
Sorry for keep asking, I want to eliminate the chance to make a critical mistake.

No, see my post below. You don't need resistors because the motor outputs are only 5v NOT 24v

Thanks to @AndyUK who post his UCCNC set up at his building thread and to all the other guys in the forum, I manage to see my steppers move for the very first time last night.
Thanks everyone for the support!

Here is Andy's post:http://www.mycncuk.com/threads/11552...084#post126084
