Hi I've been trying to configure my lathe for threading and I think I'm missing something. I have the 5i20+7i33 mesa card + servos + 100 lines encoder attached to the spindle
The threading are incorrect, so I've been looking to what can be wrong, and I find that the "motion.spindle-revs" not correspond with the reality. When there is only 1 to 5 revolution the value is almost correct, but when the spindle rotated more than 50 revolution the gaps between the read value and real is increased. So I would think that making rigid tapping it would work, but not for multi-pass threading because the increasing error. I think that my .hal file in not properly done, I miss something. So I ask for help please! Thanks a lot Arnoldo Riter Here is the block I added in order to make threading, but I doesn't work properly!! #### 100-line encoder gives 400 pulses per rev### setp m5i20.0.enc-03-scale 400 net spindle-pos m5i20.0.enc-03-position net spindle-pos motion.spindle-revs net spindle-index-en motion.spindle-index-enable net spindle-index-en m5i20.0.enc-03-index-enable ------------------------------------------------------------------------------ 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
