Hello I present myself : Pascal Lelievre, new to this list, living in france. I've got a german CNC Router AL640 from Team-Haase, with stepper-motors. I'm using EMC2 since a few weeks and I'm satisfied about it.
I'm more a lurker here, as most of the messages you all post are for me a little bit like dark magic to me (I'm 'learning' CNC and CNC use , that's not my main job, and I have to learn everything) I noticed this problem trying to mill some circles and the 'joint 0' error occured when trying to mill , after having milled successfully 1/4th of the circle, on the G1 command where only 'pure Y-axis' move was required. I wondered about this and played with the G61 , G61.1 options, to no avail, the problem was still there. As I wasn't really happy from some 'corners' which came out rather circular somewhere else on the job, I digged in the G-Code explanations and found the G64 Px.xx instruction very usefull. Something remains to me a mistery : the value given as parameter for the G64 P command was/is smaller than the FERROR and MIN_FERROR given in the ini file , so I don't understand why a smaller error gives a better result . I had imagined that a smaller errors induce more constraints than a relaxed parameter ? So it works , but I'm not sure I really understand why ? (well I made the assumption FERROR, MIN_FERROR and the G64 Px.XX parameter where somehow linked, this might be wrong.) Sorry if this sounds a stupid question, I'm just a beginner here.
