SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT

[TomKerekes]

Hi Noel,

i am trying to find out how to set the machine to make smooth transitions from one segment to an other, lets say it start cutting a straight line at 400 ipm, then slow down almost stop at the corner make the turn and accelerate again to the next point, like driving a car.
it is all this controlled by the parameters facet angle, corner tolerance, collinear tolerance, break angle?

The main thing that will affect "smoothness" is the Acceleration setting in the Trajectory Planner. The acceleration will determine how fast the motion slows down and speeds up.

The Break Angle determines if the machine will stop at the corner or not. If the change in direction between the two lines is more than the Break Angle then the motion will come to a complete stop at the corner.

If the change in direction is less than the break angle then the corner will be rounded and the motion will not come to a complete stop. The Corner Tolerance will determine how much the corner is rounded. The larger the corner tolerance the less the motion will need to be slowed down to make the Corner (curve).

You might see here and here.

thank you Tom

other issue i have is, sometimes the owner machine call me to tell me the software just lost it's configuration, when he turn the machine on, it open at the original screen like when you download the software the first time, so i have to run to his shop and load the config again, i know sometimes when the computer lost power happen this situation but is there any way to avoid this?

Hi Noel,

KMotionCNC automatically keeps a backup of GCodeConfigCNC.txt as GCodeConfigCNC.txt.bak and should use it if GCodeConfigCNC.txt becomes missing or corrupted. When the problem occurs do any of these exist int the \KMotion\Data folder when the problem occurs?

I'm not aware of anyone else with this problem.

What Version are you using?

Is the Operator commonly turning off power to the PC without shutting down?

If the problem persists you might make a Windows batch file that the Operator can click to restore GCodeConfigCNC.txt from some backup location so you don't have to always run over there.

the operator is turning the pc off normally, then turn off the kflop power supply from the ups, i don't know if the ups is causing any noise that can cause the lost of configuration, it happen sometimes not always, this is the 3rd time that it happen, the version is Kmotion435f.



thanks

I assume you mean the Operator is doing a Windows Shut Down and not turning off the PC.

Version 4.35f has the backup file.

Hello Mr. Tom

I have a challenge with the design of a cnc router machine for a custom application, the thing is that it need to have two independent router heads running on the same gantry, and two rotary axis lathe, each spindle has to have it's own ATC, they are going to work with the same Gcode program but sometimes running on the same direction and sometimes opposite direction like a mirror to get one right and one left machined part, i would like to have a button just to tell the software work on mirror or work in the same direction, or maybe an M code to give the instruction, the Y axis always will be the same, since the gantry is the same and also the Z axis will work together, is there any C program example to make an axis follow an other axis, for example, A axis follow X axis and sometimes plus rotation and sometimes negative rotation? can it be slaved?

Hi Noel,

It seems like slaving would work. You could slave the 2nd Z Axis. You could slave the 2nd X axis with +1 gain to follow or -1 gain to mirror.

Hi Tom

Can be used a field bus device to communicate I/O functions between kflop and machine actuators, sensors etc.

Thanks

[TomKerekes]

Hi Noel,

I'm not sure I understand.

Could you explain what you are trying to achieve.

[NOELNOG]

Hi Tom

What I try to ask is about fieldbus systems, i have a cnc router that i have to retrofit with kflop, i found that it uses this fieldbus for comunicate I/O from the controller to the machine devices like sensors, valves, etc, so there is one electronic card in the control cabinet and there are two more cards in the machine's gantry, they comunicate with only two wires shielded cable, so i assume they send signals back and forward, but uses some protocols to control all different devices, this is to avoid lot of wiring and noise i guess, so maybe the easiest way for me is remove all that and wire up all from kflop to machine devices.

this is the kind of system i talking about
