Updating To Latest Version

Tom,
Iam updating my mill to the latest version 4.34 and was wondering if there is a simple way to update KmotionCNC? Or do i need to launch KMCNC from the new install and reconfigure it? This is how i have done it in the past.

Thanks,
Troy

Re: DMM-TECH Analog Tunning

Hay Tom, So i tried to use Quadrature mode and just got growling. Then i switch back to Step/Dir mode and got very rough movement in one direction and would continue in that direction when axis should be returning back to start with much more growling of motor. So after chasing my tail and checking ...

Re: DMM-TECH Analog Tunning

Just to compare things. I tried step,dir signal. But have a issue. in closed loop step, the green output line in plot stays flat. I show encoder counts.
Any idea?

Re: DMM-TECH Analog Tunning

When servo is not moving i can rotate ballscrew by hand and move table about .007" before i can feel any holding of servo. What parameter setting am i missing?

Re: DMM-TECH Analog Tunning

Hay Tom, A couple of times I did try adding some "I" value of .001 and got runaway conditions. Also tried a value of .0001 which cause some oscillation. But, am going to start over with tuning and follow the steps in link. For some reason i always forget where that tuning info is. :roll: In step 4 i...

Distance to Go DROs

Hello Tom, 1st, nice to see a Dynomotion forum :) Even tho iam a little late. Was there ever added to KMCNC a DRO that would show how much further an axis has to move before that line of gcode is finished? BTW, iam starting on my lathe now. What would you prefer? Post here about it with progress,pic...
