General Mach Discussion / Re: velocity

I appreciate the help.  That's why I couldn't change my steps per.  My accuracy is fine.  I just needed to gain speed. 

thanks

THANK YOU!!!

Taking it to 45 got me to 175 ipm, which is close enough.  Runs great thanks again

In motor tuning when I change the steps per  then it changes my max velocity that I can set.  I set my steps per by distance traveled and compared that to what the 'axis calibration" came up with.   The problem I'm having is that the max setting for velocity in motor tuning is 98 with steps per at 15245.  It is a cantilever gantry used for waterjet work.  It is very smooth at 130 ipm.  The only way I can seem to get it to that speed is to boost my feed rate to 200%

Thanks

I need to speed up my machine.  The only way I can seem to up my max speed is to change my steps per.  Any suggestions?  My steps per is set at 15245 and I can only go up to about 98imp.  I need to move at about twice that.

Thanks

Thanks for the feed back.  Thats a shame.  I wish it worked.  At least it's not just ME being stupid!!
Wish it was though because I need that feature.

General Mach Discussion / reverse run

« on: April 14, 2008, 06:23:51 PM »

When I hit "Feed Hold" and then hit "Reverse run", my head goes in a totally different direction (sometimes off the beaten path!)

Any help?

Thanks

General Mach Discussion / losing steps?

« on: April 14, 2008, 06:06:52 PM »

Newb questions  I'll have lots of them!
1)  How do I know if I'm "losing steps"?
2)  If run I my router out 6' on x and y sometimes I'll gain an extra .125" on x.  When I cut a simple 2"x2" square my x axis has extra .125" on x.  Stepper motors
           
3)  What is Step pulse and Dir pulse in motor tuning?  They are set at 5.

Thanks
