What Tom means when he mentions using a C program with a few lines of code to control the PWM, is each servo loop/channel within the KFlop outputs a value. With normal servo/stepper use, the channel configuration will handle that value internally. However if you want to do something 'non-standard', ...

I'm just getting back into this, and I'm looking for thoughts on the tool/speeds/feed selection. As it stands, everything has to be selected/set for each operation. Things like speed/feed are really set per tool. What I'm thinking, is have an extra page/screen for creating speed/feed profiles i.e. s...

I've just realised you posted in the User PC Apps forum. You'll need to do the actual homing routine using a C program, as the lag between PC and KFlop is to slow to detect bit changes quickly (IIRC it's around 10Hz), unless you run homing at a very slow speed. Easiest option is to create a couple b...

If you just want to correct the maximum speed, then simply change the 255s to whatever relates to your maximum speed.

If you want to measure and correct the speed over the speed range, then look at the KStepPWMCorrected.c example in the KStep folder.

Can you post what code you've already written?

I'm going to guess that during use, those parameters are stored within the KFlop? My initial thought was a custom screen that allows you to view/edit those parameters, then have the KFlop push them out a text file, although I'm not sure if the KFlop would be able to read the values back in, plus it ...

You are correct in that you need to use an alternative method, as KFlop only works in axis counts and has no idea regarding the XYZ positions. The simplest method I can think of, is to use KflopToKMotionCNCFunctions.c, and the MDI function. Here's a quick example from a C program I've been working o...

I'll second the ethernet interface request :-) Regarding the differential outputs, if you're interested, I've got a batch of PCBs for outputting the JP5 step/dir outputs to differential outputs. They have two RJ connectors for input/output, with jumpers to select if signals are passed straight throu...

Tom, so I've got enough code to reverse until the probe clears, however as you've mentioned using SetFROTemp is less than ideal (moving at 5IPM it pushes my test box about 10thou before reversing). I've switched to using SetFROwRateTemp(), and set a randomly selected time of 0.1, which appears to wo...

Hi Moray, motion is reversed for a calculated time (I suspect this may need a bit additional calculation to reliably clear the trigger event the set distance to allow for acceleration/deceleration) Any reason not to reverse until the probe active goes away? That could be an option, but personally I...
