  • no no ... I expect that the axis whose endstop is pressed stops ... that the others go ahead too! the problem is that nothing stops! Can you tell me the interrupt called from the end stop? I have external drivers for the motor and then step,enable …
  • I checked the functioning and the disturbances on the endstop signal with my oscilloscope: the signal is perfect and with all the motors running there is no noise! help ... help ... why does my firmware ignore end stops when multiple axes move? I re…
  • can you tell me where to find the interupt function that is called from the endstop?
  • Is possible to have a debug mode for endstop? in other words, display the status of the endsto in the message list during printing?
  • Yes, homing work . when printing, if only one axis moves then, everything works on that axis. but if there are two axes to move, no. in fact: if I launch a print and hold xmax endstop, in the first movement that will make the x axis alone then it …
  • I have made a new test cable ... outside of the printer ... nothing ... it don't work at all!! is impossible! i am wrong ... but where? this is my configuration  // ################ Endstop configuration ##################### #define MULTI_ZENDST…
  • done the test with 2k resistors! absolutely nothing has changed ... sometimes they work sometimes not! I also redid all the connectors ... the last thing I have to do is change cables using screens and change the path of the same. My printer is buil…
  • tonight I made a card that includes 2k resistors. tomorrow I try and report the result, hoping that it can also serve others!
  • My manual of radds says: ‘connect the mechanical endstop to the gnd and signal pins so they are normally closed ( push = open)’ ! but it's right??? should not I connect to 3.3 volts? With gnd connected i have only the tension from the internal resis…
  • I am working araund the schematics of radds. There are a capacitor (10nF) from signal and gnd. I have a pullup ( into the processor #define actived) that should keep the tension high. Ok ; my endstop is normaly closed and if i measure the tension on…
  • I am making test. If i send G01 X150 F300 and i push the end stop all work fine but if i send G01 X150 Y150 F300 isn’t ! It is random ... one time work and one time not! I have noise ... sure! how to fix it?
  • Ok, but i have #define endstop_pullup_(all)_min ( and Max) set to true, i have #define endstop_(all)_(min and max)_inverting false and #define (min and max)_hardware_endstop_(all) true. Then #define always_check_endstop 1! The hardware is a A…
  • sorry ... I'm still used to the old card! yes, it's 3.3 volts! I currently have the mechanical switch connected between the signal and gnd! everything works, manually , but not during printing! I understood that you suggested me to add a resistor ..…
  • Ok, so ... i try 50k resistor! I always have 5 volts on the line ... so I guess I need to connect the pin signal on the gnd, when the endstop is crushed the line will go faster to gnd ... right?
  • even if I'm working with a normally closed circuit, should I put a pulldown resistor on the signal? what value is the resistance? I'm working with Arduino Due and radds.
  • I checked now but it was already 1!
  • thank you!!! but because it is not set by default !!!
  • Yes, I know ... but I already had this display. I welded a connection cable only for lcd and encoder (no sd card). The display also accepts 3.3 volt values ​​...
  • Yes ... 2 in italian is ‘due’ ! fantastic, you have been clear! I get it
  • Perfect! I have the same controller for all stepper!
  • I use DM542T
  • i suppose Invert direction (INVERT_Z_DIR) Invert enable signal (Z_ENABLE_ON) ... but for STEP ??
