Thanks Stef, I was wondering if you had designed them around your intended use ( or safety factor ). Keep up the posts, really enjoy them!

Thanks for the link Pete.

Stef,

Can't say enough about your build. I've done a few and this one is beautiful and inspiring, especially the creative methods to avoid shipping parts our for 3rd party finishing. I've read...

Hi Tom, further details:

I went into the registry and found multiple references to files within the KMotion432 directory. As a result, I uninstalled KMotion432 entirely, rebooted and reran the...

Thanks Ben, although after fighting this for near two years, it doesn't feel significant enough to call this a solution... ;) Tom, what gives here, anything make sense to you?

Guys, had an odd evening while trying to get the step response screens for Ben. I did two things:

1. Fixed the c program file.
2. Removed the old KMotion432 from the root drive into a new sub...

I will try and answer in order:


I was running the trajectory at 1 IPM acceleration up until I retuned on Sunday, with exactly the same results, so I think we can table this one?



Ok, I...

Hi Tom, it does wait u till the fault apparently. I watched the one I posted and the thread stayed green until the fault triggered it, about 5 minutes of run time. I am running the same CNC Program...

Ok, here is the test. With Tom Kerekes kind help I built a test program last year and modified it a bit yesterday. Here is what it is supposed to do:


Wait for a trigger, then record data for...

Since I expect this to be a bit of a process, and have received some replies from Tom K via email, I will start from the beginning and add his replies in as able.

My system:

Hi Tom,

Since this is all related to the issue I emailed you, I am going to start a new thread with the right title and I will use the thread instead of email.

Machine: 3 Axis DIY CNC using Kflop, Kanalog, Snapamp and kmotionCNC.

I use the Step/Response screen to tune the motors, and the supply voltage trend is very helpful. I believe I am having an...

Understood, I will get a converter. I just reread your explanation above and had a lightbulb moment:


So I am definitely going to connect the encoder simulation back to the flop and try and have...

I will do that.

Tom, would you mind taking a look at the attached page - it's the stepper/quadrature input pinout to the DB9 on the Moog T200. I would be curious which axis and which pins you...

Awesome, thanks Tom, long time no speak. I will assume the T200 can maintain the position accurately for now. The part that's scrambling my thoughts is the timing question in an open loop, but I...

Question - hopefully Tom is still around... :)

I'm finally taking the step of converting the spindle from VFD to Servo based Spindle. The primary reason is to do synchronous tapping (some folks...

Ben, I've read through your post and greatly appreciated your help file. I've been fighting a converted mill for almost a year now, and I haven't had any luck with stopping random following errors. ...

Fired up Sprutcam 9 yesterday and went to post process and all my post processing options are gone. I looked in the directory, and they are all there with *.sppx extensions. The post processor...

OMG. After all that, when I restarted my computer, kmotioncnc changed to MM. I have been in and out of kmotionccnc for over 1 week and it never changed, and this cost me 3 hours of head banging. ...

Further data for you to digest:

1. I have calculated 20,000 cpr or ppr based on ball screw and encoder.
2. In kmotion, jogging an axis 20000 results in exactly one inch.
3. I finally found the...

Tom, I have kmotioncnc working gcode, but am running into an issue. In Mach3, I can identify where to specify the counts per rev and revs per inch, but I haven't seen an obvious place to specify...

I will give it a shot! Thanks Tom.

Hi Tom, Figured out the initialization program by looking at some of your other posts.

I just put a photologik OPB940 slotted photoeye that is tripped every time around by the spindle. I'd like...

Thanks Tom, I do see the discontinuity and will do some checking. Two questions on using the C function:

1. Is that included in a setup or initialization program you would recommend creating and...

Hi Tom, ok, I have the spindle working, in fact have added some modifiers to the spindledefs to "curve" match the non-linear nature of the VFD to output. Not happy with the tolerance, will...

Ok Tom, I believe I have connected the dots. I modified one of your user programs, but I am not understanding what variable kmotioncnc uses to pass the requested speed to my C program, nor if there...

Good morning Tom, one test completed and three questions remain.

I swapped the C11T board back in place of the C6 and it works on the wider pulse length as well. I haven't had time to test the...

Ok, I thought I would try something and it appears to have worked. I put this in the program screen and then hit the button that says, compile, download and run:

Then using the console...

Just edited post, wrong image again.

I looked back and the PNG file I uploaded was missing the ground circuit. Here is the updated diagram that reflects current wiring (and has the ground - it's been there all along, my apologies). I...
