Third party software and hardware support forums. / Motor tuning moving 2 axis's

« on: May 21, 2018, 06:41:39 PM »

I am in the process of converting a Lagun Mill to Mach3. I have installed DMM Dyn4 servos and drives controlled by a UC400ETH controller coupled to a SainSmart 5 axis breakout board.
Everything seems to work fine when I am jogging the axis's using either the keyboard or the pendant.
However, when I go into motor tuning, the Y axis sets fine, the X axis has different results each time and when I try to set the Z axis and tell it to move, the Y axis will move several steps just as the Z begins its initial move. This movement is not just a mechanical shift due to play, it is obviously being powered for second when it should not be.
Not sure if the issue is with Mach3, the controller or the breakout board.
Any ideas would be appreciated.

General Mach Discussion / Mach3 "Run form here" quit working

« on: September 23, 2014, 06:15:06 PM »

Hello all,

I am hoping one of you has experienced this problem and can help me find a solution.

I am running a CNC Plasma table using Mach3. I am creating my g-code using Sheetcam. Everything has been working fine including the run from here function in Mach3. That is until I installed a Proma THC and a floating z axis last weekend. The THC and the floating z work as expected (although I will likely up-grade to a better THC in the future).

However since the installation, I have discovered that I am no longer able to stop the machine and then restart using the "run from here function". Whenever I try, the Mach3 software resets to the  line immediately following the first line of g-code containing a g31 code instead of the line requested. It also does not give me the usual reposition request. So, I am forced to reload the code and run from line 1 anytime I stop the code.

Any help would be greatly appreciated.
