Re: DMM-TECH Analog Tunning

Hi Tom, Did some more tuning now that i know i was looking at the error plots wrong. Added the Feed Forward and replaced filter with 2nd order. This filter made motors quieter ,idle and running. Feed Forward helped a lot. Now i figure it is within .0005". This is what i was expecting out of this mac...

Re: DMM-TECH Analog Tunning

Hay Tom, Forgot to mention that after increasing P and I that the servo holding stiffened up nicely. I can no longer rotate ball screw by hand when ad idle. When reading the error plot which should i focus as the overall error, the height of tallest spikes or the difference between the 2 lines on th...

Re: DMM-TECH Analog Tunning

Hi Tom, So i made some changes as you said and checked voltages. The voltages looks like the highest is 5V and average around3.5-4v on the Analog screen with DAC highest at 1100 and average about 550-650. This was done running a test move of 5" or 203200 counts. I have also made some other changes. ...

Re: DMM-TECH Analog Tunning

I can still easily rotate ballscrew and show about 5 counts in the Axis Position window. When in Step/Dir i could not move it at all. What settings affect this? I...

Re: DMM-TECH Analog Tunning

Hi Tom, The Velocity setting is what i was able to achieve in CL Step/Direction mode. It was very fast. :) But in Analog it wants to runaway real easy. Thats why i only did a 1" (20320) move. m_murray gave me his settings from his 4th axis(Analog mode), just got done trying them and info in your lin...

Re: DMM-TECH Analog Tunning

Hi Tom, Ok, now that i have the Z axis mount reworked and filters on drives, as i mentioned on the CNCzone post, iam ready to try Analog mode again. Attached is just a base movement so far on X axis under Analog Closed Loop. This is a test move of 1.0" (20320 counts). I didnt move further as i was w...

Re: G73 Quick Peck Drill

Some controls allow a certain amount to retract by another letter designation while retaining the normal 'R' plane of return. And other controls (Fanuc) are hard coded so when a G73 (also know as Chip Breaker) is issued they will retract say .010-.015" at the end of each peck. Which is normally enou...

Re: Updating To Latest Version

Hi Tom,
Work great.
Just a note, i have custom screens and buttons so had to copy folders 'res' and 'Screens' from directory ...PC VC Examples\KMotionCNC.
Is there any other files that i should copy over for my custom screens? So far all appears ok.

Thanks,
Troy
