Tom, My mill is working very well now. It's not perfect, but for a 40+ year old machine with steppers and belt driven axes, operated by a man with limited knowledge and experience, I think it's as good as it can be. Thank you again for your help through the process. In answer to some of the question...

Tom, I have the plus plan. The free version does not allow access to ChatGPT 4o, which is the most advanced version at this time. Nor does it allow for file uploads, which is the thing that really made the difference for me. I had a great deal of difficulty identifying changes (positive or negative)...

Tom, I just wanted to follow up and 'close the loop' on the issue I was having machining small circles. The problem, as you suspected, was with improper acceleration and PID values. I had experimented for countless hours, unrewardingly, until deciding to ask ChatGPT for help. After gathering basic i...

Tom, Thank you VERY much for this information. Unfortunately, I have not been able to get back into the shop to test anything yet. When I do, I will report back. Before emailing you, I experimented quite a bit with acceleration, reducing it considerably without noticable effect. I have the Max follo...

Thanks for your willingness to help. My mill uses closed loop steppers controlled only by KFLOP, not by the stepper drivers. I am using the Mach3 plug in, not KmotionCNC, however, I experience the same issues using KmotionCNC. This is the GCodeConfigCNC.txt file from the Kmotion data folder: m_Setup...

Tom, I’ve been using my SuperMax knee mill with KFLOP and closed-loop steppers to CNC mill printed circuit boards. I’m running the spindle at 2500 RPM with carbide end mills and drills. At a feed rate of 1 inch per minute, the results are very acceptable (photo attached). 1 ipm.JPG However, as I inc...

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...
