shaiss. Disable with -1#define NUM_SERVOS 3 #define Z_ENDSTOP_SERVO_NR 0 #define SERVO_ENDSTOP_ANGLES {{0,0}, {0,0}, {10,90}} 3. This gets the fan spinning reliably before setting a PWM value. Pull-ups resistances It is a good practice to use a pull-up or pull-down circuit for a basic switch. I am in the process of moving the electronics off my … I'm trying to have the Z-axis Min input pin not supply 5v. Successfully merging a pull request may close this issue. Everyone who contributed a "solution" in the form of a working firmware.bin or configuration.h used the z-endstop (therefore "solution"). There are two main types of endstops. The other important aspect of an endstop is protecting the hardware from damage. However, I believe the pull-ups might cause problems with PNP sensors - luckily most common sensors are meant to replace a switch and are thus NPN which work fine with the pull-ups. A further improvement would be to configure the endstop pull-up/pull-down settings automatically if one of these is set, unless specifically overridden. November 2016 edited November 2016 in Questions & Answers. Hi, The ENDSTOPS_ALWAYS_ON_DEFAULT seems to have no effect The Z axis homes in the centre of the plate but I cannot get it to move below the homed position which always is a couple of mm above the bed. to your account. privacy statement. I have motors moving and it is seeing my opto endstops. Boards could have had a BOARD_HARDWARE_ENDSTOP_PULLUP or BOARD_HARDWARE_ENDSTOP_PULLDOWN configuration definition. By clicking “Sign up for GitHub”, you agree to our terms of service and Defines the minimal speed for the main fan, run in PWM mode. Use `clean_up_after_endstop_move()` when G28 is ready instead of the same literal code. #define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS. For example, if the board has BOARD_HARDWARE_ENDSTOP_PULLUP defined and ENDSTOPPULLUPS is not enabled in Configuration.h, this would generate an error and halt compilation. Endstops are reported as either “open” or “TRIGGERED”. Board configuration to include end-stop pull-up/pull-down status flag. Sync planner before the actual moves in `run_z_probe()` are done, to guarantee the move is only in z direction. Enable AUTO_BED_LEVELING_FEATURE and Z_SAFE_HOMING: #define … Note that endstop switches themselves tend to trigger at slightly different positions, so a difference of a couple of microsteps is likely the result of endstop inaccuracies. hobergenix. The pull-down resistor R1 which is connected with the ground or 0V. Have a question about this project? The big difficulty is gathering data on enough boards to start with for it to make sense. Forum List Message List New Topic. Already on GitHub? What would you like to do? If I disable the pull-up resistor for my Z-axis endstop, should I read any voltage at the connector on the board? Perhaps someone in the audience? The same thing is true for the Pull-down resistor. With homing the firmware moves all axis until it hits the endstop. Have a question about this project? That means the z endstop pin doesnt work. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. This would then check for incompatibilities with the ENDSTOPPULLUPS setting in Configuration.h.. For example, if the board has BOARD_HARDWARE_ENDSTOP_PULLUP defined and … Once you compile Marlin, that’s it. Both NC and NO switches should have a pull-up so the onboard pull-ups should not cause any issues using a mix of NC and NO switches as long as you set _ENDSTOP_INVERTING appropriately. Use this command to get the current state of all endstops, useful for setup and troubleshooting. But I think there are no external pull-ups. We’ll occasionally send you account related emails. It is an 8 mm one and functions correctly with aluminium foil under the glass bed. Duet Maestro endstop inputs. Des lignes a commenter ou decommenter ?
