I discovered that i have a problem with small carvings and very fine details. I tried 2 times to carve a stamp from aluminum ~30mm diameter, X and Y started slowly to loose position. Lowered the acceleration from 3000 to 1000, did a dry run also.

Same problem persists. .


Now the question is: the controller??? or the servos need further tuning??? or i have to slow further things down, which i dont believe is the case. I remember i bumped up servos quite much to be responsive via software and even 3000 accelerations and more than 10000 mm/m speeds on objects like 200x200cm there was no problem at all. Checked initially the machine, does not seem to have sth loose.


Any ideas??? Could that be the small lines? Exported v carving file as arcs also, same again. Thinking about it it looses both X and Y and moves slowly in diagonal on every step down of the Z is visible. At the end of tool path controller shows same machine coordinates as on start 0.

Should i try to find the look ahead in the controller and make it bigger, i was thinking of disabling drawing the tool paths?


i don know what exactly to do now except bump more the servo response and see what happens
