Motors stalling /growling
« on: May 01, 2019, 09:34:34 PM »
I am very new at this, I have 34 stepper motors and on the Y & A axis I get stalling /growling when in the jog mode and also when trying to run the demo in mach 3. Mostly when I stop and start.  I have check settings, wiring, looks right. My x and z seems to do find. I have changed settings in motor tuning and I have to go back to my original setting. Can anyone help?

You have FIRST to make sure that the microstep settings at the Stepper drivers are set correctly first.
Check that it is set to 1600 steps per rev. (NOT ANY SETTINGS HIGHER than that)

Check motor tuning. It seems tat your acceleration is too high.
Make no mistake between my personality and my attitude.
My personality is who I am.
My attitude depends on who you are.

when you say micro step settings at the stepper drivers are set correctly first, you mean the switches? if so i have done that and did change them and had to go back with the original settings. but not sure how to set the 1600 steps per rev. can you explain how?
ill also check the motor tuning again.

Yes the switches.
What is the model of your driver?

For example, if the driver is DM860T then its SW5 SW6 SW7 SW8 should be ON OFF ON ON
(see attached)
YOUR driver should have it's own chart.

Please see attached to set SW1 SW2 SW3.
I am guessing that your motors are rated 3.5A max current.
Are your motors running better now?

Yes they are 3.5 A.
I have not be able to get back to the shop yet to reset things as of yet, hoping to today, for sure tomorrow. 
My settings was my problem i guess, i was told to set my steps per to 4000 so i'm hoping that was my problem.
I'll post my results when change them.
Thanks
