What about adding a G64 P... or similar? Even with a very small P of a few hundredth of a millimeter it improves the situation significantly. I have some experience on the 840D and I do not think that it behaves differently. If you run the 840D in G60 mode (default), it will also stop after each G1/0 move and re-accelerate. So I do not think there's a difference between 840D and EMC here. The machine does what you program. So if you program a stop every 5 microns, it will completely halt every 5 microns. -- Greetings Michael. -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

> The basic question I guess is would EMC be able to provice the same tool > path quality as the (lower end) Siemens or Heidenhain controllers? You should run EMC in simulator mode, and use halscope or halstreamer to record all the joint positions to disk. Then you can analyze this data later for correctness/smoothness. It is fairly easy to "choke" the EMC interpreter/traj-planner with G-code which consists of many many short G01-segments. It could be argued that these should be filtered to longer lines, arcs, biarcs or NURBS G-code, but if you have a CAM-program that only outputs these short G01-segments this could become a problem. Even with a hobby mill this is an issue. We have 5m/min rapids on our machine and when programming a contouring operation at say for example 2m/min feedrate, if the CAM-program outputs lots and lots of short G01-segments the EMC interpreter/traj-planner will not handle it well and the actual feedrate may be 1m/min or even lower. You should be able to test for this in simulator mode (see above). Improving the trajectory-planner is not an easy task. I think the consensus reached last time we were discussing this is that it is a very hard task indeed _unless_ some restrictions are added. For example restricting traj-planner to only 3-axis trivkins and/or restricting feed-override to 0-100% (not >100%). Also I think there is a restriction of one G-code block (or canon-command) per servo thread cycle. If you run a normal servo-thread at 1ms that means 1000-lines of G-code per second (in theory). If your CAM-program outputs more than this you will get the slowed down feedrate I mentioned above. As mentioned by other posters this is a problem you rarely encounter with hobby-grade machines because it only occurs with "bad" CAM-code which consists of the many many small G01 segments and with high-speed machinery where you want to cut at 5m/min or 10m/min (or more!). When you have this kind of cash invested in the machine, the tooling, and are under time-pressure to have to run your machine at 10m/min then suddenly I think investing another 10k or 20k in a pro controller is not a problem... (contrast to sitting down, learning all the innards of emc2, learning trajectory-planning math/geometry, and attempting to write a high-speed traj-planner for EMC2) Anders -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

Re: [Emc-users] EMC as an alternative to Heidenhain iTNC 530, Siemens 840D, etc.
Would they sell this bare bones? Since it wouldn't make much sense to pay for the control and then not use it. If they want a sell, ask if they can sell it with a Simodrive 611U instead of 611D, the 611U would take analog inputs and then emc2 would have no issues making this work with mesa cards. And you would get to keep quality drives/servos. Tell them what you try to do and see how far you can talk them out of a complete machine. I would think they make more money on their machine than the control and if they are a competent builder, they should be able to sell a control-less machine with the digital drives replaced by Siemens' analog drives. Obviously i am applying an highly idealistic "Kunde ist Koenig" thinking, but if i had the budget to get a well build new machine w/o control and add emc2 to it as means of ultimate budget extension, to go from 3+2 to full 5 axis control, i would go for it. EMC2 may have made this thinking even worse, i want my cake and eat it too now. I sure hope our lathe emc2 conversion works out well, because taking emc2 to the mills would be even more interestingI like mills more than lathes :) On Wed, Sep 8, 2010 at 1:00 PM, Florian Rist wrote: > Hi, > I need a new machine for (rather light, no heavy machining of cast iron > or stainless stsel) 5axes simultainus milling in research and > development and education.

And the current status of emc is that it is not even able to run can or something like ethercat(TM) ethernet/ip. (I will give etherlab a try when I get the hardware next week) b) one has to switch the digital drives built in to accepting pulse signals as stepper simulation or even worse accept analog input. and for plc one has to either rewire the sps inputs or use an external s7 sps to drive the simatic i/o's. Either way one will need a simens technican. And the costs of doing this will outweight buying a 840. bye Ulf -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

Hi, I need a new machine for (rather light, no heavy machining of cast iron or stainless stsel) 5axes simultainus milling in research and development and education. Since I'm on a short budged I start thinking about getting a cheep 5axes machine, not capable of 5aces milling by default, but equipped with strong enough servos and good encodes on the aces rotary axes and then replace the 3+2 axes controller by EMC (capable of 5 axes interpolation). One of the machines that might be used for that conversion the the DMU DMG eco 50 (haven't verified it the rotary aces hardware is strong enough, yet) : http://www.dmgecoline.com/de-DE/30-dmu-50-eco So, what do you think, would EMC be able to keep up with the Siemens 810D controller?

All the programming, simulation, collision checking etc, is done off-line using CATIA, HyperMill, SprutCAM or self made CAD-to-CAM scripts (no collision checking her, hu...).
