Linuxcnc 2.7.15 released - query regarding TP bugfixes was created by curtisa
Hi guys,
Noticed that 2.7.15 has just been made public - nice!
Have a quick query regarding a couple of the changes listed for the trajectory planner. I notice that there are a couple of bug fixes listed for arc blending:
Are any of the above related to an older issue with momentary 'hiccups' when performing some arc moves, like this one for example?

Have a quick query regarding a couple of the changes listed for the trajectory planner. I notice that there are a couple of bug fixes listed for arc blending:
TP: fix fallback to parabolic blending when tangent blend fails (fixes #477)
TP: fix accel violation with G96 and arc blending
TP: fix exact-stop when falling back to alternative blend methods
TP: fix accel violations with near-tangent segments (fixes #546)
TP: apply minimum displacement checks consistently (fixes #550)Are any of the above related to an older issue with momentary 'hiccups' when performing some arc moves, like this one for example?

Never mind - just updated to 2.7.15 and tried a couple of gcodes that used to give me occasional stop-starts during helical moves, and the problem seems to have gone away!
Nice work, Devs!
