Thanks Tom The machine was equipped with an old Analam CNC system when I bought it 20 years ago. The X, Y, and Z axes each had a single limit switch that was triggered by adjustable bumpers at each end of travel. When I motorized and encoded the knee, I kept the concept similar. Before reconfiguring...

Tom, I have my (+) and (-) limit switches on each axis wired in series and connected to opto-inputs on KFLOP. The limit switch option selected is 'Stop movement' I am using Mach3 and an iMach pendant to move the axes. When the X axis is driven into the (+) motion limit switch, the axis stops immedia...

Tom, After a little tweaking to customize it to my system, WatchDogStatusRequests works perfectly to disable all drives whenever Mach3 closes. I also brought the 12V that is used to activate the SSR which switches on the drives, in series with a manual switch (which allows me to cut power to the dri...

Hello Tom, Everything now is working as expected. The startup runaway problem was solved by having KFLOP enable the drives - Thanks again! Is there a way to have the KFLOP also disable the drives when KMotion or Mach3 is closed, rather than when the KFLOP board is rebooted or powered down? The way I...

Thank you Tom.

I made some simple wiring changes and now all of the drives can be enabled using SetBit(155);

I looked at the watchenable.c script and can see how it would be very useful.

How is the program called?

Is it added to the initialization program?

Jim

The CW CWW inputs to the drives are wired directly to the KFLOP outputs for each axes. Your thought that they may be 'floating' and picking up interference is a great one. Having the drives enabled by KFLOP is a also a very good idea and I think the hardware/wiring part would be easy, as I have alre...

Here is the link to the motor driver: https://www.applied-motion.com/s/product/stepservo-drive-ethernetipssdc10ip/01t5i000000y0d9AAA?name=SSDC10-IP-StepSERVO-Drive-with-multiple-control-options-10-A-EtherNet-IP-w-Modbus-TCP It can be configured to operate in either step/direction or analog input for...

I am using a KFLOP with the Kanalog expansion board to control 5 Applied Motion Step Servo Drives and motors and a VFD intalled on a SuperMax knee mill. I use the Watchdog FET switch (SWE output) on JP8 to close a contactor that energizes the motor drivers and VFD after the KFLOP boots. I am using a...

Tom, Thank you. I will give it a try. I discovered a good work around (before receiving your reply). I added code in the HomeEncoderMach3 program to also reference the C axis whenever the 'ref A' button is pressed. This allows me to reference each axis separately using buttons on the Diagnostics pag...

Tom, Great information about the Mach3 flags - Thanks! Here's what I found after the testing you recommended: When I press the individual 'Ref axis' buttons on Mach3's Diagnostic screen, Kmotion's console confirms accurate receipt of each signal (i.e. a value of 1 for X, 2 for Y .... 32 for C), and ...
