Re: Min Max Spindle Settings in KmotionCNC

Tom, I already have my spindle C keeping the min and max. However, the slider would be limited in functionality if a drastically poor S value was used. The reality is this should not be an issue with normal use where my C is keeping it within usable range and my CAM's post is limiting gcode. For me ...

Min Max Spindle Settings in KmotionCNC

Is there anywhere to set minimum and maximum valid spindle RPM in KMotionCNC?

The application would be to prevent S values from improper gcode or slider action not to go beyond acceptable. Similar to the feed rate except a minimum would also be used.

Thanks.

Re: Spindle Override Displayed Value Updating

I do not plan on spindle feedback for now. The DRO solution worked well. Thanks. Interesting that the bar graphs do not show in the screen editor while a Kflop is not connected. They also do not function with the KStep where no encoders are present. I can see the usefulness where functionality, or l...

Re: Linear Scales and Backlash

Thanks, Guys. Moray, what scales did you use on your CMM? Tom, Moray is correct in that there is an additional channel "R." The functionality is similar to what he noted. The distance between the R's vary so you can determine where on the scale you are. That is what I was referring to as pseudo abso...

Linear Scales and Backlash

I wasn't sure which forum board to post this. Miscellaneous? I have this older little Sherline Mill I am nearly finished retrofitting. It needs encoders of some flavor to close the KStep stepper loop. As a bit of a science experiment before I invest in the process on my larger machines, I am plannin...

Spindle Override Displayed Value Updating

I am now using the KStep to control my spindle via the 10v analog output. My new C programs seem to be working for all of the spindle control buttons on my new screens as well. What I am missing is any output on the S speed override at anytime. Whether running at 1, under, or over. I do not have any...

Re: Kstep and Minarik Spindle Drive

I made a basic follower circuit with a 2222a NPN transistor and a 4.7k resistor. Maybe I need some other components, but this worked. Here is the schematic I followed (image from wikipedia): follower.png The circuit seems to work well. If it should have further components please advise. Turns out my...

Re: Kstep and Minarik Spindle Drive

I did disconnect it from the drive and the voltage output from Kstep was correctly at 10v. Kstep and my code seem to be functioning properly (using your example code with my spindle settings and also have output 255 directly to pwm for confirmation). When I have the drive wired, the voltage output i...

Kstep and Minarik Spindle Drive

I am trying to use Kstep to control an older Minarik DC motor drive to control my spindle on an older Sherline mill. I attached the manual for the drive. See pages 11 and 12 for reference. The drive needs 0-10vDC signal. After a lot of head scratching, I discovered the drive seems to suck a lot of p...

Re: Safe Z Spindle off Restart error

Thanks, Tom. I get following errors when I use the Move command over longer distances. I tried it over a shorter distance and everything does perform correctly. When I figure out what I have set wrong and get my tune better, I am sure this will work perfectly well.
