I have my STEPS PER at 4000, my microstep at 1/4. The native STEPS (no microstepping) is 1000 = 1 inch. I have the velocity set to 120 and the accel to 24 (20%).....
I'm 100% that it is I that is doing something wrong but I'm not seeing it.
Hmm, now I'm wondering about my Jog. I'm wondering if the speed I see when jogging in MOTOR TUNE is actually a lower velocity than selected (lower than 120, which of course would be wrong) and that the velocity I see when RAPIDS occur in the cut program is actually the correct speed for what I have selected (120)......
Now that I'm calculating what 120 would be in terms of velocity, it would be 2 inches/second. Pretty damn fast......So, now I have something to look at and that would be the jog speed I see in tuning.....
Just went to have a look at my jog speed....Sure enough, it was set to 25% and the velocity I was seeing when tuning was 1/4 the velocity set....What a dope! That explains it all. Like most people I was tuning by eye/ear and selecting a "comfortable velocity" by eye instead of actually working the numbers like I just did above.
I'll have to lower the velocity to around 60 and the accel to 12 and of course change my jog speed to 100%!!....That should do it!
Thanks for the help,
