MK1 Steel router build log 1500x800x200

So i ordered this simple 5 axis bob.

Leadshine manual says put 2k resistors in series.

Anyway, 4 axis pulse and dir 8 resistors
Maybe order 2 more for 5th axis.


Did you guys use a resistorbank for this ?

You bought a UC300eth for the controller?, the supply, and outputs from this are 5V and you do not require the use of resistors. Okay, you're connecting this to the 5-axis BoB - that will also require a 5V supply, and the motor outputs from that will be 5V level (the BoB may have a 12-24V input to supply the PWM 0-10V spindle speed controller (though I can't see any evidence of the circuitry for this on the image linked) - but will also require a 5V supply for the on board logic devices). Again - no need for resistors.

My words of caution on that BoB - there's no evidence of opto-isolated inputs on that BoB - which leads me to believe that all inputs (from switchgear, limits, e-stops etc) must also be referenced to a 5V supply.
