It took me a year or so to do the research and collect the parts for my conversion. I had some problems such as false triggering of my limit inputs, which I solved with a debounce software hal component. In all cases, the forum members here helped me understand and solve the problem, usually within hours. Peter W. from Mesa was very, very helpful. No one can hand you an ini or hal file that will work perfectly the first time you turn on your machine, since all machines are different. I encourage you to stick with your 5i23 and work with the community by supplying them with error messages and good descriptions of the problem. I will be happy to post my hal and ini files as soon as I can document the configuration that I am using it for. Have you visited Anders Wallins site http://www.anderswallin.net/tag/cnc/ yet? If you explore his site, you will find his hal and ini files some of which I copied in my spindle speed setup. I had to do my Emc2 conversion under a lot of time pressure do to the fact that my old controller broke down in the middle of a job I was doing for a paying customer. The fact that I was able to resume making the same parts very accurately (more accurate actually) after the conversion was remarkable. I will be finished with it in a week, and I will put up a web page or blog with info related to my conversion at that time and alert the community accordingly. good luck, Tom -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

(Ahem) Thanks for the insight into the causes of chatter. Thanks to John too. I have been curious re: the proper way to use tapered ball end mills, so now is the time to find out. Upgrading to Emc2 has opened a virtual wonderland of machining capabilities that I could only dream of when I was working/fighting with the Bandit controller. I only have a week of machine time under my belt with Emc2, but it feels longer. I tried enlarging the corner radii in the pockets, which only let me go faster and make nastier noises in the corners. I think Mastercam has high speed machining strategies that will reduce cutter embedding/burial in the corners. With the old Bandit controller high speed machining was a joke, so now with EMC2 I have more toys to try out than time to try them. When I finish with the current work, I will tweak the G64 P-X settings and try out some of the high speed bells and whistles under the hood of Mastercam. If I get any noteworthy results, I will post them.

Of course, the taper makes the shank end stiffer, which is good, but the buildup of resonances is a major factor in chatter, too. I think the differing diameters seems to prevent these resonances.

Tom, bravo ! Are the parallel marks inside the part made on purpose or due to the multi layer milling ?

Emc2 community, I finally produced my first part on my new Kasuga/Emc2 (Mesa 5i20/7i33) knee mill conversion. I am very happy with the results! The mill will do 500 ipm rapids, and feeds so far can hit 30 ipm with very accurate results. Lots of tiny moves tend to slow the feedrates down a bit, but I have no complaints. See the following video sample of the toolpath being cut for a lightening pocket: http://www.youtube.com/watch?v=jWd29Vv1gcA Here is how I am handling manual tool changes: http://www.youtube.com/watch?v=Y2whmSV74vw Some more photos of the conversion and the first part to come from it (the part is a heavy duty triple tree for a V8 powered trike - to give you an idea of the scale, the polished fork tube in the following photos is 2" dia.): http://www.foxpointdesign.com/cnc_stuff/conversion_sm.jpg http://www.foxpointdesign.com/cnc_stuff/firstpart2sm.jpg http://www.foxpointdesign.com/cnc_stuff/tripleT-sm.jpg http://www.foxpointdesign.com/cnc_stuff/tripleT-sm.jpg http://www.foxpointdesign.com/cnc_stuff/ttclamp2-sm.jpg The parts are coming out s fine. No dwell marks, no backlash comp marks, just nice smooth surfaces. Accuracy is dead-on. I'm really happy right now :-) A hearty thank you to all of you who have taken the time and dedication to post your conversion information (Anders W.), as well as those who wrote the software, made the interface boards, and graciously answered all my questions and put up with my stupidities (Chris R., Peter W., Sebastian, John K., Alex, Kirk, Stephen W.P., et al.)
