[Emc-users] AXIS display and 'g-code driving me loopy...'
Hi, After playing with Ed's scripts which work fine for my purpose, my frustration with AXIS has grown. I wish I was able to modify it but I'm not clever enough :-( . I appreciate that the cause of my frustration is not to do strictly with the way AXIS works - it does so very well - but with the way it is limited in displaying some scripts relating to rotary axes. In the case of Ed's scripts, you set the Y-axis zero to coincide with the edge of the disk or cylinder you wish to cut teeth into and the script then cuts a groove along the X-axis, returns and rotates the A-axis, then repeating until all teeth are cut. The AXIS display, however, shows only a single toolpath which it repeats while the tool angle changes around the X-axis. Whilst giving a fair interpretation of what the script is asking for, this doesn't really relate to what one sees when looking at the machine where the work, not the tool, is rotating around the A-axis and each toolpath generates a new cut which remains permanent. I guess what I am suggesting is that it would be nice if there could be a feature in AXIS which would allow you to offset the X, Y and/or Z axes from the tool position (to put the tool on the edge of the rotating work) and for the repeating cuts (toolpaths) already made to be shown arrayed around the relevant axis. Is this possible? While on this subject, would it also be possible to make the axes interchangeable? I'm sure there are a number of people who have 4-axis machines who, like me, tend to use the rotary axis in different positions. In the real world, or on a multi-axis machine, each of these different positions - parallel to the each of the three linear axes - would normally have its own axis designation A, B or C. However, in our world, the rotary axis always seems to be A whichever way it is mounted and so, again, the AXIS display doesn't reflect what is really happening on the machine. It is, of course, possible to give the axis parallel to the Y-axis, the designation of B in our scripts but, to do so would require a new .ini file to handle that axis and, as far as I can tell, AXIS is not capable at the moment of displaying a B-axis. While actually cutting the work, these limitations are probably not too significant but they do take on some significance when you are trying to develop a script and verify that it is going to work correctly before you commit to hacking at metal.. I realise that I am probably asking for the moon but it would be nice if these points could be considered in any future development of AXIS or any other display system. Thank you, Ian Ian W.

Re: [Emc-users] AXIS display and 'g-code driving me loopy...'
I agree that what you describe would be great, and really lift AXIS up to a whole new level when it comes to previewing gcode for 3 axis machines. One stumbling block is that there are a lot of different possible machines (maybe as many as 120 for machines up to 5 axes; I haven't completely thought this through). Another is that things that are currently straight lines in the preview (e.g., G0 X0 A0) may or may not become curved in this kind of preview. With that complaint about the difficulty of the feature out of the way, I hope I'll be able to work on this feature sometime in the next month or so. I think it would be a pity for emc2.3 to not have this implemented, at least for a few specific machine configurations. My first target will hopefully hit all the hard parts: the 5-axis machines that can be commanded in XYZ AB UVW coordinates. Jeff - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] servo with brake issue
Thank you all, Thomas, Noel, Ray for the help and suggestions, After trying almost everything, we even build a filter circuit for the 24V line up to the brake we discovered a faulty pin connection on the motor connector. This wasn't all, the ground in the building was not that good either and a UPS was used to power the PC and the IO boards, this took care of the false limit switch trigger that we where seeing. So ironically it was something very simple. I was suspecting that it was something like this. It's been a while since I've had to debug something.

I have been BLITZED a number of times by defective grounds, and systems where multiple pieces of equipment were plugged into different outlets. I had a ground in a house I used to own where a romex staple had pierced the safety ground and tied it to hot. The staple was driven with the power off, and it cut the safety ground back to the breaker panel, so the hot and ground were connected together with no short, and just left that way. It took me WAY too long to find that one! Jon - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Mini-itx Control
Kirk, I have had trouble getting Linux to run on my C3 ITX board, but that was quite a while ago. I would be interested in knowing if anyone has gotten EMC2 or Linux to run on one of these. It would make a nice low power router/gateway or EMC2 remote. I have had good success using the Via C7 mini-itx boards (see: http://www.mini-box.com/Hybrid-C7-1-5G?sc=8category=99). The main problem I had was between some power supplies and the IDE Flash module (4 GB) I was using. Changing either the power supply or the flash module has remedied the problem. I talked to the PS manufacturer, and the problem seems to be with the rise time of the 5V (IDE bus) relative to the 12V which powers the flash module. The result was that the system did not boot reliably. The PS manufacturer suggested putting a cap on the 5V (I tried once without success), but changing to a different flash module fixed the problem for me, so I have not re-investigated. I use a riser card for the Mesa 5i20 board. The first enclosure I used was from mini-box, but the Mesa board did not mount very well, so I went to a Travla enclosure which does a better job of accommodating the Mesa board and comes with panel mount brackets. I was also able to get EMC to run under the smaller footprint Xubuntu on this board. Real simple actually, all that was really required was to run the install script manually.

Both true. I get around the single PCI slot by adding a dual riser card but if I populate that slot with a Mesa I can build up a pretty impressive system in a pretty small space. As for cheap, I'm as much into it as the next person but I also like some stability over time and Jetway assured me that there were four more years of the board I've got. Try that with a consumer board. I've got two identical boxes built the same week with different versions of mobo. m2cw Ray - This SF.net email is sponsored by: Microsoft Defy all challenges.
