Hello,
Iam building a DIY CNC embroidery machine, and where are jump stitches
(bigger than 10mm x example) I need to activate a command
to release thread tension, preventing needle bending, thread breakage
or fabric deformation.
This command will activate a 12 volts solenoid (from car door)
who pull a pin in thread tensioner and release thread.
I neet to set a 5vd input relay / out put 12vdc, Any sugestion?
How can I configure Mach and controller connection for this?
Thanks in advance
Rene

please see schematic.
use TIP122 for transistor.

I made my own Solid state relay for high current devices (a big solenoid coincidentally);

but for run-of-the-mill stuff I have several of these little guys:

Solid state. Fast, silent, work great with MACH. For 8 bucks, it's not worth getting out the soldering iron . .
Just watch your current draw and make sure you use something that can handle it.
They have a nice selection of BOBs as well. I use their C1G . . . love the status LEDs on each pin!

Hello Simpson, thanks

Hello
Im planning to move a 24DC motor in a new CNC Project.
I have a Hobby CNC pro controller and a C9 DC Solid State Relay from CNC4PC capable to drive from 6-60dcvolts motor and 10 A.
My plan is connect Relay to Pin 1 in CNC Controller, and activate in this way,
My question is.
Is necessary to connect some device between Pin 1 and 5VDC Relay connector?
Thanks in advance.
