Ok - I found another issue. I have been playing with the little terco mill. Z kept losing steps. I figured noise or running too fast... well dad said - maybe linuxcnc is erroring.. I thought no way. I have tested the new tp extensively.. :)
well.... I ran the config in sim with the peak readings and it looks like the z axis's velocity constraints are violated. Here is a screenshot of halscope. z axis has a max velocity of 1in/s (60in/min) You can see that it violates the velocity - peaks at 1.6in/sec. (positive and negative) http://imagebin.org/304984 here is a screenshot of the whole run - it peaks at 2in/sec at some point. (way faster than that axis can go) http://imagebin.org/304985 here is the ini http://pastebin.ca/2694160 here is a short snippet of gcode. (it violates velocity -1.6in/sec) http://pastebin.ca/2694169 dad always seems to be right.... sam On 03/28/2014 06:40 PM, Robert Ellenberg wrote: > It turned out that the max feed override defaulted to zero if not set in > the INI, which caused the velocity to be set to zero.
