Hi Craig,
Got power supply up and running, tried all you suggest still no movement, DIR voltage toggles from 0v to 5v when "X" axis is changed direction on output of TB6600, my scope is only basic but there is a pules and the pulses ramp from 5v downwards on output of BoB to TB6600
I have tried my motors ("X" and "A" cloned with an Arduino and these motors work fine albeit had a bit of a problem with skipping using at first, but trial and error using CNC Shioeld and DRV8825 drivers at least got it running reasonably smoothly albeit frying a Uno board and a couple of DRV8825's, I used Universal G-Code Sender and I am using Nema 17 motors think on my first impression my setup is underpowered, But, will upgrade once get working
My other thought was Stepper Driver switches on the TB6600 SW1 - SW6 I have set OFF/ON/OFF/ON/ON/OFF i.e 8 micro step/1600 pulse per rev..Current 1.5amp PK 1.7 Amp.
When I tried running with Arduino, the Nema 17 motors would only run with CNC Shield set to no jumpers to M01 jumper i.e Full step and half step higher wouldn't run not sure if that is relevant but if I increased by putting MO2 and MO3 jumpers in motor would not run.
The other thing I was going to try was using an Arduino to drive the TB6600 that could confirm if SW1 to 6 are correct, there are lots of YouTube ideas but my end goal is to use Mach3.
I would be most grateful for any help from the results I have so far.
I also enc a pic of pulses on scope.
Regards John
