In kmotionCNC when gcode executed it looks like G0 commands respect acceleration and jerk limits set in Kflop but G1 - does not. Or may be G1 respect just acceeration but not jerk.

And then what...

Hi,
Yes, the MaxLimit did the trick. Now was able to reach +/-50um error which is +/-22 encoder counts. Could that be considered normal/typical? To me it looks reasonable and I tended to accept...

Thanks for tip. Tried "CL Step" output but it does limit pulse frequency to preset kflop max velocity and this solutin has not helped as seen in new screens. The input/output is scaled to real world...

Hello,

I'm using kflop with servo drives which takes STEP/DIR position input. The Kflop is set for STEP/DIR output but this seems to invalidate any PID loop parameters.
Whatever is set in P,I,D...

what is the right way to feed ("software connect") output of one PID loop to the position input of another loop?
I'm trying to improve response of plasma Volt/Zaxis control. Suspicion is that due to...

Hi,

quick question, what is a right way to abort motion of MoveExp() ? Should we use Jog(ch,0)?

In my situation here is 2 axes - one following another with second loop which represent...

Hi,
Is it possible to see the result of what trajectroy planner does on KMotionCNC simulator?
I'm trying to simutate 1x1 square corner roundings with 0.3 corner tolerance and 1deg facet angle.
But...

Hi,

I'm faced limitation of Kmotion Gcode interpreter which is inherited from NIST RS274NGC when using toll radius compensation - it does not allow conacave corners.
Is there any solution how to...

Hi all,

Planning to use XP45 with FineCut ohmic kit and somebody told that tip is isolated from electrode and sensing can be used also when arc is On. Is that true?
My cirtcuit has relay which...

Hi all,

Looking in to Neuron THC controller and its description confuses me at one place:



Can someone explain what is that? How can ohmic sensor be switched on and measure something while...

Hi,

The system has X,A and Z axes. That is a 3D tube cutter simlar to this: https://www.youtube.com/watch?v=mDO9sx8NiPA
X,A axes are part of coord motion while Z is not. Control software is...

Hi Tom,

Thanks. Can you suggest how is better to implement plasma Torch Height control of the Z axis vs Voltage:
I have voltage signal as quadrature encoder to one spare axis Input(~700kHz) and...

Hi,

Somewhere in example code have seen comment that MoveExp() function includes WaitNexTimeSlice(). Is that true?
And if so - which other functions include WaitNexTimeSlice()?
Would need to...

Hi Tom,

Yes, verified - removing filter fixes overshoot problem.
Solved, thanks.

Hi Tom,

Thanks for input.

I dont know why but all the mess when using "false" in Interpreter->Interpret() was caused by the altering single motion param after InitializeInterp(). Possibly...

Hi Tom,

the InitializeInterp() is called as startup. If I use false in Interpreter->Interpret() the motion instead of commanded position (i.e. A30) goes to (current position+dest_pos)*25.4 ...

then executing G code:
(CMD,EnableAxis0)
(CMD,EnableAxis1)
G0 X800 A60
(BUF,WaitBitBuf53)
(BUF,SetBitBuf52)
(BUF,WaitBitBuf54)
G1 X900
X100
X900

hi all,

I'm trying to programically set fixture offsets in C++ before G code execution.
In the KMotionCNC it is done by issuing pure g text command line aka "G54" which invovles createing/saving...

that is same as was suggested in initial header post. "chan[CHNO_X].Position" type syntax allows to put some definition in to [] braces. And later "EnableAxis" seems to reset destination to current...

That does not work. It alters destination but not current position. Verified this on console. "Pos" reads the same value before and after EnableAxisDest:

392523

quick Q:

how do we set arbitrary encoder position when homing in C file instead of Zero(ch)?

is that right:
DisableAxis(CHNO_X);
chan[CHNO_X].Position =...

ok, clear. And (-1) seems to be a way to disbale this feature when not required. Thanks.

It looks like before executing preset user button action to execute C programm the ActionIndex is writtent the persistVariable[VAR]. Why and what for is that?
Strangelly the offset is user defined...

Hello TomKerekes & islander261,

Is there any update on this project? I also need to make a fast PID THC, integrated with KFLOP for cutting 0.6mm (24ga) stainless sheet. Does the approach described...
