Testing with 3 axis

The machine itself isn't yet finished, there is missing few parts of z-axis.

I made my first test's with SS and I'm very impressed! The setup was easy and motors are running very fast and smoothly.

Thanks for replying so quickly! System is now working, I started to look closer enable pins and found out that each axis had wrong enable pin number 
Motor runs now great! I had also oppoturnity to test my new microstepping stepmotor drives.

Thanks!

SmoothStepper USB / SS: Motors won't turn yet

« on: January 02, 2009, 11:12:09 AM »

Hi everyone. I just connected my SS and tried to make first trials with motors. BUT I can't get motors run. I have done everything by following the instructions of manual. Where to start troubleshooting? The setup is new but I double checked the motor wires etc. everything is fine. Only thing what I noticed was that when I try to turn motor by hand, there is normal holding torque. But when I command mach to turn motor, holding torque decreases (normal?).
Plugins and SS are installed.

When Mach3 is running and SS powered up, blue and green LED's are lit and red is blinking, does this mean that there is error with configuration?

BR, Mikko

I got this BOB pcb for free when I bought three professional stepperdrivers. Usually you should be able to trust the designer that he has done precice job.. That pin order-thing should be self-evident. But thanks anyway for replys!

Hi! I'll send xml later, I'm at work at this moment. I started to look closer LPT connector and noticed that connector's pins are mirrored on pcb! So pin #1 is actually #13 and #14 is #25 etc.  I don't know is this done by purpose but pins would be ok if connector is soldered from bottom of pcb. I think that BOB designer has done mistake here.
Can I change Mach pin order so I can use this BOB anyway?

There is no difference is Reset on or off. Enable shows very low voltage, <0,01V. I also checked other axes, results are strange:

Y step: 4,78V
Y dir: 0,07V
Enable: ~0V

Z step: 0,07V
Y dir: 0,07V
Enable: ~0V

EDIT:

I checked the A axis as well, enable shows 4,7V, Step and Dir = 0,4V. I connected motor here, now motor have normal holding torque but still I don't have a movement on motor. How the difference between these pins can be so big?

EDIT2:

Motor is turning when I checked the Max CL mode enabled? Motor turns only one direction. And the only working axis is the A ax

I checked the pins with voltmeter, results are these:

Step = 4,78V
Dir = 4,78V
+5 = 5V
Enable = 0V

Enable stays in 0V no matter is the g-code running etc. Here's the schematic of the BOB: http://www.netikka.net/mikko.kuivamaki/bobv2.pdf (currently I don't have that 1K resistor net in BOB, still looking fo it)

For x-axis: Step pin 2, Dir pin 3, enable pin 14

Hi everybody!

I bought new motor drivers & simple BOB. I have used 3d-step almost 1,5 years. I tried to test new driver today but motor won't turn. I doubt that there is problems with enabling the driver. I have configured Mach3 and motor should be enabled on Output tab (Enable1= port 1, pin 14 and enable is checked) Step and Dir have been also configured. The only thing what is missing of BOB, is pull-up resistor-net for limits (I looked BOB schematic and noticed that it's not required for enable pin, enable pin 14 comes straight to the driver from LPT). Motor doesn't have holding torque when driver is powered. What to do next?
