Sudden Misbehaving
« on: April 15, 2008, 12:19:35 PM »
Hey everyone.

I just recently got my first machine built and working. I had everything configured and set up with the machine moving and taking commands well from mach3 all that was left was a little tuning to get the acceleration and velocity dialed in. I could get good speeds up to about 30in/min and attributed that to needing to tweak and tune the machine.

Yesterday when I tried using the machine and getting some adjustment done, I fired it up and went to jog the machine and nothing...I thought I broke something so I tried again and noticed that it did actually do something, but it was sending only 1 pulse every 4-5 seconds and it was gradually getting a little faster as I held it longer and the acceleration caught up to full speed. I haven't adjusted anything from the last working configuration before it started doing this.

I can rule out defects with the router, my driver board, and the power supply because the router works well and has good speeds while using EMC under linux on the same computer. Any suggestions, I am new to mach and don't know if there is any other pertinent information i left out.

Thank you  ???

Sounds like you turned the accel. waaaaaay down in motor tuning to me. Check all of your motor tuning settings.
