Seems weird that a homing switch would suddenly fail like that, I've only had the machine for a couple of weeks, but it's the only explanation I can think of. Traduit et adapté de l’original chez PreciseBits. I naively thought that the "GRBL compatible" mode would make smoothieware behave like GRBL, but it does not. Could not find limit switch within search distance. /** * Use stallGuard2 to sense an obstacle and trigger an endstop. 000 $131=850. 000 $121=400. // - If stepper drivers time out, it will need X and Y homing again before Z homing. also, “homing only” is for the carbide homing switches, which are not full +/- axis limit switches… but +axis only… so of course i want hard limits enabled. 在系统进行初始化时,我们需要初始化GRBL的配置参数,函数的本体如下: void settings_init() { read_global_settings, 如果返回有错,进行处理:DEBUG输出,设置为默认初始化值,再一次DEBUG输出。. 4 board, there’s no dedicated power-control pin, so I connected the Coolant output to the same DC-DC SSR I tried out with the RAMPS board:. 8) could that have any effect on control? i looked at the synthetos board and will most likely get one shortly. The 10 k limits the current into the arduino input pin to (9-5)/10k = 0. $26 Homing switch debounce delay 250 milliseconds Sets a short delay between phases of homing cycle to let a switch debounce. X and Y jog functions are working correctly. I think that the sender is overflowing grbl's buffer causing grbl to misinterpret commands. The only setting I've changed is the invert limit pins as the NC switches are now behind the opto isolator board.
