somethings amiss here.
p2 on the breakout board is a steady 1.58 volts in both directions.
p4 is at 1.54 in both dir
so it seems there might be an issue with p2 and p4?

here you can a test of the 25pol cable to make sure that P2 and P4 are connected here.

and for additional testing i think a oszlisocope is needed to check P2,P4 and P6 that there
a pulse stream is created.

mach3 can not "record" the movements, but what you can do is,
create 3 Buttons.

1.-button1 -> create teachfile

2. enter in MDI Spindlespeed , Start spindle, start coolant and what else you Need

3.-jop to a Position

4.-press button2 witch put's the actual Position with a "G1 Xactpos Zactpos" into the file

5.-repeat 3. and 4. so many times you what

6.-press button3 to end teaching

button1 and button3 allredy exist in 1024 screenset (more or less).

i mean how it was shown in the two Videos

PUL+ to  P2
PUL-  to  GND
DIR+ to  P3
DIR-  to  GND
ENABLE to 5 volt power supply

and so on

i am out for today, it is getting late here.

same thing happens with p2 to ground and p4 to ground so it would appear the controllers are fine?

yes that means all Motor Controllers are working.

i would now Z axis P6/P7 as shown in my Video

step- and dir- to GND
step+ to P6
dir+ to P7

that is one of the last ideas now

don't Forget to Setup p6/p7 in Port's&pin's


1145
yes it appears to be doing just that

means Motor Controller is working

1146
p to ground

and if you test Px to 5V, because this is the way the Motor controllers are connected.one pin is enough

1147
so if you take the wire from p6, witch is the step Signal from z, and put it GND ,away from GND, and back to GND
by Hand the Motor should do one step every time you do this.

somethings amiss here. p2 on the breakout board is a steady 1.58 volts in both directions.
p3 is at 5.14 in the down dir. 1.58 in the up dir
p4 is at 1.54 in both dir
p5 is at 5.14 in the left dir 1.58 in the right dir
p6 is at 5.14 in to down dir 1.58 in the up dir
p7 is at 5.14 in the page down dir. 1.58 in the up dir
so it seems there might be an issue with p2 and p4?
What are your thoughts?

have you connected a Motor to p6/p7 they seam to work

did you measure PX to GND  or PX to 5V?

Motor Controllers connected or not?

1149
my readings were a steady 3.32 volts.

but 3.32v one direction and 0V other direction?

ok, could not find any specifaction of the breackout bord, that it is working with 3,3V PP.

you can do the same test at the Outputs of the breakout board.
