Hi

I have just recieved a new Kflop Ver 1.3.
I am using vb.net interface to run stepper motors but not having any luck, i was originally testing machine on a vers 1.2 board and
motors moved fine by just running software in vb.net folder of Kmotion434. I am trying to move 1 motor at the moment vers 1.3 board, i get a postion change on screen for axis but no stepper motor movement.

I am supplying 5v to step+ and direction+ from kflop, step- pin 16 and direction- pin 18 to stepper driver .

I have tried jogging motors in KMotionCNC same postions change on screen but no movement of stepper motor
In KMotion I/O screen I/O10 and I/O11 are showing state selected and output not selected, on ver1.2 board it showed output selected

I did intially wire stepper drivers incorrectly could this have damaged new Kflop board?

Or am i missing something in setup of board?

Hi Gary,

KFLOP Version 1.3 is fully hardware/software compatible with Version 1.2. Version 1.3 is just less noise sensitive to resets on the reset input.

I suspect you are not configuring the KFLOP Axis Channels. When a KFLOP Axis Channel is configured to use Step/Dir pins and Enabled then those IOs should be configured as Outputs.

Maybe you flashed the configuration into the old board? We don't recommend Flashing anything into KFLOP for exactly this reason. Better to simply have your App configure the board as needed each time.

HTH

Hi Tom

Got stepper motor running using config & flash and step response in KMotion.exe, but when i change the velocity parameter to speed up jogging of motor in .net app main function (Public Class DynoMotionVBnetProvider) the motor runs at only 1 speed regardless of value i use for velocity
If i use step & response screen in Kmotion.exe and change velocity the motor does run faster or slower depending on values entered.


Thanks for your help
Gary

Hi Gary,

You would need to tell us how things are configured and what methods you are calling to cause motion.

Hi Tom

I made a stupid error in not adjusting jog speed variable.
feel a bit stupid about post, hey well you live and learn.

Thanks
Gary
