Tuning problems

Great that did it thanks a bunch! OK. now I have a new problem. When I start the program it runs so slow, and it sounds horrible! I had it running great in stepconf. ???????


Sorry Harry I missed your post I was having limit issues, but those are resolved and I'm off to new problems as stated above.

After getting the limits figured and the scale, it's maddening I'm so close to being done..... When I run a program the axis move slow and vibrate and are quite loud! My setup is an X2 mini mill with ballscrew concversion. Keling 4030 drivers and keling C10 breakout board. Drivers set to half stepping and so is AXIS.

Does the machine go to where it is commanded or does it lose steps?
On the mdi page is the speed override set lower than 100%
Have you checked the power supply is the proper voltage and amps?
Are the drivers set for the proper amps?
On the MDI if you enter...

Does the machine make the proper moves at speed, end up where it started and sound O.K.?
Most steppers can vibrate at certain low rpms.

I know when I ran my system in half stepping with my old software it sounded bad as well
(especially at low speeds), going to quarter stepping does make it sound a lot more pleasant.

But my understanding is as you move from half to quarter
stepping you may loose a little torque on the stepper motors.

Rick Yes it does except at low speed it vibrates a lot. I think I'm gonna try 1/4 stepping n see how that works out. thanks

Harry I think your right
thanks

Thanks to everyone for the help, I'll post an update after I try 1/4 stepping.

OK well, moving to quarter step did quiet things down. However now I seem to be losing steps. Before in half step It was dead on 1" = 1" but now it's obviously losing steps. Sometimes it's right or close to it. Others it's way off. Especially when making rapid movements. I also ran into another problem, it seems I've got some binding in my Y axis due to the ballscrew not being perfectly horizontal. Hopefully fixing that will help alot.

I wanted to ask if anyone new how to properly set up the acceleration, ramping, velocity?

SubMicro

Yes I figured some of it was from binding, I'm addressing that issue today! I'm running @ 36v 2.8a. I've read through the manuals, but they seem to me, to be written for someone with alot more experience with this stuff than me!
I'll go back and re-RTFM......

SubMicro

Get all your mechanical issues solved first ..binding, loose couplers, ways etc.
Then retest.
At first make your adjustment large say reduce acceleration by 25% see if that helps.
Also reduce velocity you can loose steps by setting the velocity and or the acceleration too high.
The gradually bring the velocity up till you find your best speed, same with acceleration.

When you find the best combination back off from both the acceleration and the velocity to give yourself a margin of error for working in the real world with a load on the machine.

Thanks for the tips guys. As soon as this redneck gets the binding issue finnished, I'll do like you suggested. Thanks again Ya'all!
