need help! with drivers

[lamicron]

I have installed some nema 34 1160 oz motors from keling,(X and Y) I can jog them a little and then the stop in the DRO (MACH) start to blink. I have set them bipolar and set the current to 6.4 .
For the Z axis I have a nema 24 595 oz motor, it doesn´t start but gets warm.
>Dont know what to do, I have changed acceleration and velocity , but nothing changes.

Does it say soft limit activated? Is your soft limit buttom turned off?

[lamicron]

It says: external stop requested when it starts to blink.

Do you have the estop connected? If no, then change the settings in Config (top left corner) then Port and Pins then Input Signals tab and scroll to Estop and disable it for now.

[lamicron]

Yes I have it in low, then i´ll disable tomorrow and tell what happens.
Thanks for help

I ´ve disbled the estop, had to put a 0 in the port, now the machine works, but have no Estop. I have checked the stopsbut everything is ok, tomorrow i´ll change the pin in the board, any other idea???

I have some noise and vibration problem with the 1160 oz motors. I set the steps per at 60 as result of the fine tunning to get the same travel as the dro. My resolution is 1/8, gear and rack 20 pitch , 20 teeth, pulleys 3:1and have set the motors at 6.4 v parallel con. Am, I rigth?

[DennisCNC]

You have a power supply of 6.4v to the motor drives? or do you mean Amps?
Do yo have micro-stepping drives? What brand drives?

[lamicron]

I get it from Keling , he already told me 6.4 v is ok in the driver (current settings)
what I´m not really sure is about the steps per.
Scott from MACH told me to use the setting for steps in the mach dro- settings.
I have changed the velocity and accel but noise continues..

[DennisCNC]

What do you have the micro step setting on the drive?
What drive model do you have:?

driver 8078, set at 1/8 (1600 steps)

This will be your steps per inch:

1527.88745368219522338128


1,600 x 3 / pi= 1527.8874536821952233812841283761

your 20 tooth gear has a pitch diameter of 1 so it will go (pi) distance in one revolution.

Sorry I missed the 1/8 in your last post.
