General Mach Discussion / Re: Multipass for threadmilling wizard?
« on: December 24, 2007, 12:16:26 AM »
Thanks, I'm a newbie and the wizards are a big help, I like the spoonfeeding :)  I cut the threads before reading your post. Single pass and real slow. Threads look great but a lot of the rod was unsuported and I would have preferred lighter cuts. I'll try your suggestion next time.
Thanks, Shepard

General Mach Discussion / Multipass for threadmilling wizard?
« on: December 23, 2007, 06:14:13 PM »
Could someone tell me if there is a way to multipass on the threadmilling wizard and I'm missing it? If its not already there do you have any suggestions how I could do it? I'm hesitant to go full depth on a piece of drill rod.
Thanks, Shepard

I'm asking Mach's Keyway Wizard to cut .26 width with a 1/8 endmill but only get  1/8 slot. The gcode shows no change in y.  I can't figure out what I'm doing wrong. Could you get me back on track? Thank you,  Shepard

General Mach Discussion / Re: units/min drop with backlash comp on
« on: November 07, 2007, 11:01:06 AM »
When I set the accel to those speeds the speed of the reversing axis caused a jerk I can't get rid of. I lowered the amount of backlash the axis needed to compensate and solved the problem. But the amount of backlash now compensated is less than the measured backlash. Im still trying to find the sweet spot but i'm getting close.

Just contouring a simple clover leaf shaped bracket.  Once I discovered the problem I switched to a 3" pocket so I would have more feedback as I tried tweaking.

You are correct and it only happens with backlash enabled and the machine grinds to a halt. CV doesn't seem to have an impact. I've tried 5%-200% backlash speed. Though I have tried tweaking the motor accel I was refering to the shuttle accel.  I have a max speed of 100ipm but speed seems not to matter. I've been using a pocket wizard at different speeds trying to figure out the problem.
Thanks for any help, Shepard

General Mach Discussion / units/min drop with backlash comp on
« on: November 04, 2007, 10:32:02 AM »
Hello,
I have cv and backlash comp enabled. My units/min show a steady decline until I come to a dead stop over 15-20 minutes. The slow down includes jogging as well. The shuttle accel is set very high (don't know why, it was that way when I first set up) but it cuts smoothly. I set the accel down to the recommended speeds and it stops moving smoothly and picks up a jerk I can't tweak out. If someone could tell me how to keep from bogging down I would greatly appreciate it.
