LazyTurn / Strange tool path generation
« on: October 07, 2011, 06:30:28 AM »
Hi all,     The last few days i have been trying to learn Lazyturn. I read through the manual and all appendixes. Im up to the point were i have made a simple drawing in rhino CAD and inported it to lazyturn successfuly,created a tool and tried to create a rough tool path with it. The path it creates is a bit odd,im leaveing a 0.3mm clearance but the path cuts all the way up to the profile and even into the profile in some places,and on the fine finish pass it gos even deeper into the profile. on the finish path i was useing a clearance of 0. Im sure the problem is just something simple that i have overlooked but i cant figure out what.

any suggestions on what im doing wrong will be mutch appresiated

below is a pic of the tool path


General Mach Discussion / Spindle calibration problems (lathe)
« on: October 01, 2011, 11:44:23 AM »
Hi all,       I have been pulling my hair out for a few days ever since i tried the spindle calibration test in mach turn. before i ran the calib test my requested rpm and real rpm were about 150 rpm diffrence at some places in the curve and exactly right in others,but since i did the calib test i cant get full rpm and the requested rpm and real rpm are miles out. Is there a way to reset the calib test so its asif i never did it?   i did read somewere that deleting the liniearity.dat file will work but i tried it and it made no diffrence. also tried completley uninstalling mach and reinstalled it, saveing only the XML file with all my settings on but even that didnt work.

any advice or suggestions on things i could try to get it back to how it was before i did the spindle calib test will be much appresiated


General Mach Discussion / Index Pulse Setup Problems (Lathe)
« on: September 13, 2011, 04:22:57 PM »
Hi all,
I'm having problems setting up the index pulse and i'm looking for a little help.
Its counting more pulses than it should, maybe about twice as many and is not linear.
I've tried Index Debounce and any value above 0 seems to have the same effect, it shows 135 RPM no matter what my spindle speed is.
I'm using an optical sensor (Optek OPB 917 BZ) with a 60mm diameter disc and one 10mm slot.
I read on this forum that its necessary to enable Spindle Relays even if they are not used, I tried this and it didnt seem to make a difference.
Is it necessary to run Spindle Calibration Test to get the Index Pulse to work properly?
I'm using the Demo version R3.043.022 Lockdown also tried the R3.043.045 Development  but same results.
any advice or help would be much appreciated.
