Category: EMC2 Task Controller Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Chris Radek (cradek) Assigned to: Alex Joni (alex_joni) Summary: using "run from line", first move's parameters can be wrong Initial Comment: Using EMC2.1.4: Velocity and acceleration are calculated incorrectly for the initial move when using "run from line". They are calculated as if the current position is the position at the end of the previous line. But since we didn't execute that line, the tool can actually be anywhere. Consider the program 1. G20 2. G0 X0 Y0 Z0 3. G0 X1 Y1 Z1 4. M2 Run a config that has TRAJ maxvel and maxaccel higher than any axis. Clear all offsets, load this program, place the tool at X1 Y1 Z0. Now "run from" line 3. You should get an acceleration and velocity appropriate for a Z-only move (since that's what we're getting), but instead you get a/v too high: it's appropriate for the diagonal as if the tool was at 0,0,0 (which is where it would normally be at the beginning of line 3.) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=106744&aid=1703238&group_id=6744 ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
