I
am planning to build a cnc router, i have mirostepping drives & motors nema 34 of parker compumotor, needing a step+, step-, dir-,dir+, enable-, enable+ on 5 volts ttl level input , and powered from 110v external power supply. How does you connect this to a grbl with arduino uno, or a tinyg cnc controller. Controlling x & y axis with ballscrews
2 i will need to procure also a z axis + router. + vacuum system
Can you plse inform me
Regards

That's outside our range of experience.
You might want to check with someone like http://pololu.com/ who specialize in robotics. They're more familiar with high-power motors than we are.

Can you not inform me of the pinout of your tinygcodecnc & or motorshiel 3 axis, where/ how i can & may connect the step+ & step-, dir- & dir+ on 5v ttl level. Any positive answer would oblige.
Regards

Our tutorial showing how to work with the Motor Shield is here: https://learn.adafruit.com/adafruit-mot ... or-arduino
The TinyG controller is made by Syntheos, and their wiki is here: Home · synthetos/TinyG Wiki · GitHub
I don't know anything about the motors linked above, but they seem to have control modules built into them. If that's true, you wouldn't need the drive power from either a Motor Shield or the TinyG to run them.. only control signals from a microcontroller.

The drives,I mentionned, need an step- ,step+, a dir-, a dir+,ena- , ena+ input coming from the arduino uno , or tinygcnc, through or not through a motor shield. This on a 5volts ttl input voltage.
I see on what i have read that all motor shields have included low power stepperdrives, with the power output direct to the windings of direct connect stepping motor drives.(i see only 1 step 1 dir , 1 ena input per axis without sign -/ or + sign coming from the arduino uno , or tinygcnc,
I do need only to know if i can obtain a step- ,step+, a dir-, a dir+,ena- , ena+ input coming from the arduino uno , or tinygcnc, or other cheaper cnc controller. How ,and through what connection can i obtain a bidirectional +- input on 5 volts ttl level from the control into my microstepping drives (the power of the drives is coming from 110v socket).
Some positive help is appreciated. I am wondering how it is soo dificult to pick up the signals (only 1 step, 1dir, 1ena, whitout sign you are using into your shields or tinygcnc to drive steppingmotor drives connected onto your motor shields.
