Re: [Emc-users] Hardinge HCNC Retrofit/Rebuild
I have somewhat unreliable tool changes as well. Sometimes it'll miss the change entirely and spin two or three revolutions before the ladder times out. Sometimes it seems like it pops the stop too early, and catches the turret in the wrong position. Often I'll hear what sounds like the stop popping early and it'll make the correct change, but I'll hear it whack past the previous station. I'm going to try adjusting the magnet and see if that helps.

If the turret works once or twice correctly then your problem is more than likely mechanical rather than computer related. A combination of the magnetic sensor and the stop cushion is more than likely the issue. What I do if I had to remove the sensor for some reason is try to get the turret to work as best as you can without the stop cushion(just to make sure the sensor is very close to working) then fine tune with the stop cushion. It takes a little while but once you get the stop working correctly the turret will be 100 percent reliable Terry On mine, I loosen the screw for the magnet then note the actual tool position. I rotate the magnet forward (I forget which way) until the tool number matches the actual position and continue until the number changes to 0 or the next tool number. I back off a little to get the proper tool number back again. This way the logic can make a match early enough to activate the stop pawl in time. If the match isn't done in time, the table continues to rotate. See here for the lock screw location: http://www.wallacecompany.com/cnc_lathe/HNC/maint_man/ In case you haven't heard me say it before, if your seals are over three years old they should be replaced (or at least checked that they are still soft and without cracks). It made a big difference on my lathe. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- For Developers, A Lot Can Happen In A Second.

Re: [Emc-users] Nonplanar arcs
What about a new plane selection block which allowed you to define an arbitrary plane using 3 points?

It would require 3 coordinates for each of start, end and center point. The guts of linuxcnc already support this kind of motion and have for some time. The problem is representing them in gcode. I do not agree that 3 coordinates is enough to identify a 3d arc uniquely. Consider the points start:-1,0,0 center:0,0,0 end:1,0,0. You can draw many arcs with that specification. Also it is not true that you can't get nonplanar arcs in linuxcnc. If you rotate around the Z axis (G10 R) and do a G18 or G19 arc, you'll see that it's not in any plane. Of course you can only specify some arcs this way (but enough to let any gcode program keep working when rotated.) Chris -- For Developers, A Lot Can Happen In A Second.

Re: [Emc-users] Hardinge HNC
Yes, I'm ssi on IRC, and the conversion was quite straightforward. I have $400 in Mesa gear, under $200 for two vfds, and miscellaneous wiring supplies. The stock resolvers work great with mesa's 7i49, there's no problems with the Hiak amps. The only issue I ran into was dirty tachs, and they cleaned up easy enough. Conversion took about 2 weeks of evenings.

My CHNC uses encoders so that part was easy... as I understand the HNC has resolvers so you need an additional card for that. IIRC ssi on the IRC just finished converting a HNC as well as many others. I'm in the process of converting my BP Anilam CNC mill with a 5i25 + 7i77 card and a D525 motherboard which will eliminate 2 of the 3 giant electrical panels hanging off of the BP knee mill...

Re: [Emc-users] CAM / G-code Generation
Just to throw my two cents in, in addition to there being very few cam solutions, there are even fewer that do lathe profiling. The ones that do, it's listed as experimental or seems thrown in.

In the Windoze world there is CamBam (about $150 for the latest version, free for the old but still usable version) I could not get it to run under Wine. I just recently bought Vectric V-carve Pro which runs well on Wine. It will do any 2.5 D work and is excellent for artistic type stuff. I am VERY pleased with it. Price is $599. They also have Aspire which does full 3d but is out of my price range at $2000. It is a very nice piece of software however.

I think Dan is off using HeeksCAD as the easiest free solution. On the $$ side I use synergy from weber systems. The drafting is free, cam for 2.5 D is $250. IIRC, wireframe is $750 and full solids (parasolids) is $1250. The learning curve is interesting but possible even for a dummy like me. Google 'synergy cad' to get a web site. They have a 30 day trial of the full meal deal. On the non-$$ side I'm trying to learn APT; both for mental exercise and as a practical tool. Thanks for the suggestions Dave. I could live with $250 but I ultimately need some solids. So PyCAM, HeeksCAD and opencamlib that is pretty much all the open source CAM? Seems surprising.
