Hey guys,

I need some advice on how you guys connected the 8 stepper wires to the 4 wire shielded cable.

Did you guys just solder and heatshrink it to the cable?


I also feel like i need to connect the cable shield to the body of the stepper motor.

Some photos would do the trick :-)


Any advice is welcome.

I just soldered with heatshrink. Not pretty but it works :D

My stepper motors are grounded through the machine frame.
If connecting the wire shield aswell it might create a loop?

Is this any help? I wire up the Z steppers towards the end of the video.

I started by trimming the motor wires as short as I dared as this last part is not shielded. I’ve not seen anyone run the shield right to the motor. May get a ground loop if the machine is also grounded ? Not sure.

And again your skills humbled me.

You make it look so easy.

Yes heatshrinking like you did was what i intended.



For what i know about shielding..
Shield grounded to 1 side , or go all out and create a full shield EMC protection style.

Pigtaling the shield to the motor is not going to work and yes will probably create a loop if not done right.

So yes i think heatshrinking soldering is the only way forward.

Anyone working in their shop these days?
Man it is hot under a tarpaper roof

Be carful for what you say,I said that there was too much heat in my workshop and we had temperature drop here and was raining for almost one week! ;-)

Yes it is still hot :-)

Ok some pictures.

Ok have not decided yet if ill run the stepper cables directly to the drives.

I have a 1.5kW spindle and used an 18mm 2 flute router bit to skim a wooden bed without a problems. You could probably go larger - there is a larger bottom cutting type bit which others have used.

Re the CY cable screen just ground it at one end only. ie to the star point in the control box

Ok thanks for the anwsers.

+/- 50mm it is..


I started buying some bits and pieces for when the machine is finally ready.

Thanks again, will post some pictures soon.

Hi Cive S,


That bit ia a very good find actually.

I cant find any other reasonably priced multi winged bits yet.


Looks like Ebay and ali xpres only like dual winged types.

Is more cutting edges better when it comes to planing a surface?

Oh man i ve got a steep learning curve ahead of me.
