только что сделал микро ЧПУ и изучаю LinuxCNC и G -code
Имхо проще перезапустить, т.к. некоторые параметры можно задать тольк при загрущке компонентов - например количество stepgen.Geshka писал(а):И вдогонку - как перечитать INI фаил после правки не рестартуя LinuxCNC
Можешь дать пример Gкода. Что значит не точность scale - не точное задание SCALE в ini. Проще всего взять КМД по длиннее, в шпиндель воткнуть индикатор, проехать и замерить относительно этой КМД на сколько переехал шпиндель.Geshka писал(а):Можно ли с помощью G-code как либо повысить исполняемую осью ошибку так , чтобы она стала легко заметна. Например если ошибка на длинне 10 мм равна 0.1 мм, то как либо умножить проход по оси в десять раз и получить различимую и измеряемую ошибку в 1 мм. Ошибка не в люфте а именно в неточности Scale.

совсем старый стал. 2.10.1. Homing
These parameters are Homing related, for a better explanation read the Homing Configuration Chapter.
HOME = 0.0 - The position that the joint will go to upon completion of the homing sequence.
HOME_OFFSET = 0.0 - The axis position of the home switch or index pulse, in machine units. When the home point is found during the homing process, this is the position that is assigned to that point. When sharing home and limit switches and using a home sequence that will leave the home/limit switch in the toggled state the home offset can be used define the home switch position to be other than 0 if your HOME position is desired to be 0.
HOME_SEARCH_VEL = 0.0 - Initial homing velocity in machine units per second. Sign denotes direction of travel. A value of zero means assume that the current location is the home position for the machine. If your machine has no home switches you will want to leave this value at zero.
HOME_LATCH_VEL = 0.0 - Homing velocity in machine units per second to the home switch latch position. Sign denotes direction of travel.
HOME_FINAL_VEL = 0.0 - Velocity in machine units per second from home latch position to home position. If left at 0 or not included in the axis rapid velocity is used. Must be a positive number.
HOME_USE_INDEX = NO - If the encoder used for this axis has an index pulse, and the motion card has provision for this signal you may set it to yes. When it is yes, it will affect the kind of home pattern used. Currently, you can’t home to index with steppers unless you’re using stepgen in velocity mode and PID.
HOME_IGNORE_LIMITS = NO - When you use the limit switch as a home switch and the limit switch this should be set to YES. When set to YES the limit switch for this axis is ignored when homing. You must configure your homing so that at the end of your home move the home/limit switch is not in the toggled state you will get a limit switch error after the home move.
HOME_IS_SHARED = <n> - If the home input is shared by more than one axis set <n> to 1 to prevent homing from starting if the one of the shared switches is already closed. Set <n> to 0 to permit homing if a switch is closed.
HOME_SEQUENCE = <n> - Used to define the "Home All" sequence. <n> starts at 0 and no numbers may be skipped. If left out or set to -1 the joint will not be homed by the "Home All" function. More than one axis can be homed at the same time.
VOLATILE_HOME = 0 - When enabled (set to 1) this joint will be unhomed if the Machine Power is off or if E-Stop is on. This is useful if your machine has home switches and does not have position feedback such as a step and direction driven machine.
