Summary0004222: Path doesn't put Z values in g-code || Не формирует коды по Z-координате
DescriptionMade a box with barrel-like surface on x-y plane. I apply "3d pocket" the tool from Path workbench. All paths are rendered. In emulation mode, the trajectory is correct: the mill moves horizontally and vertically. Then, I export G-code as FileName.tap, and get a file with all Z coordinates at the same value, or missing Z vlues, ??or changes??. Z is moved only at the beggining, in the initial positioning. As a result, a flat surface is milled out, instead of the wanted barrel-like surface. If I mill pockets with planar floor, the pockets are milled correctly.

Is it me doing something wrong, or is it a bug?
Project and g-code files are attached.

Создал деталь, представляющую параллелепипед, с бочковидной формой на поверхности Х-У.
В верстке Path использую "3D pocked". Все пути прорисовываются, в режиме эмуляции "G-code" маршрут давижения фрезы происходит корректно: фреза перемещается и по горизонтали и по вертикали. Далее, экспортирую в G-code FileName.tap и получаю файл, в котором параметр Z содержит одинаковые значения, либо Z отсутствует с какой-то строки, либо именения. Z перемещается лишь в начале, для позиционирования на начальную точку. Как следствие, станок не позиционирует ось Z, и вместо бочковидной поверхности получается ровная плоскость.
Если задаю фрезеровать углубления с ровным дном, отверстия, Z ртрабатывает нормально.
Что я делаю не так, или это баг ?
Прилагаю файл проекта и файл с G-кодами.

Hi,Kunda1 !
Please delete subjets: " Does not generate codes by Z-coordinate ".
The problem was resolved by increasing steps of Z-coordinate.

@Kunda1 I have translated the text to the best of my understanding. I'm not familiar with Path, so I can't really comment on the validity of the issue.

@rainbowhope created a duplicate, apparently by translating this one with machine translation. I've linked it as duplicate. I hope my translation is better.

"The problem was resolved by increasing steps of Z-coordinate." - apparently, @rainbowhope found out how to resolve the problem, and asks to close both tickets. I'm not sure though.
