Да вроде уже разобрался, то что указанно в первом посте действительно параметр прямолинейности. А вот погрешность шага у выбранного мной винта составляет 300 микрон на 300 мм. (0.3мм на 300мм) что вроде тоже не особо мало? А стоит ли вообще гонятся за этими десятками/сотнями миллиметра на такой длине? Станочек был сделан не под какие-то конкретные задачи, так…разобраться в своих возможностях.
Если винт точёный, а не катаный, то 3 десятки на 300-х мм это нормально. Производители перестраховываются и указывают такой размер. В реальности думаю в полторы десятки уложаться.
вдруг кому пригодится книжка (с terrificshare.com , когда-то там пароли на пдфки давали)
