First homing attempts failing.



  • Machine uses 1 S0 style switch for x high end 1 So y low end and 1 z S0 low end. they are the reprap pursa I3 type. I have them according to my understanding configed proper, but I will let U be the judge of that. I am up loading my config file. Machine moves z up like it should, then move the x or y it's doing first about 3 mm and stops. the the DRO window show -300 mm when it was just 0. than the error message, homing x or y failed. Not sure if its a homing.g or config.g issue. no leds lit on board in non-strucck state either. however the web interface reports home switch hit, no. hit one and it say yes. Tried swapping S0 for S1 and it just reverses. never an led lit un struck like duet info state should exist.; Configuration file for Duet Ethernet (firmware version 1.19.2)

    Go to Settings->Machine Properties in the web interface and you will find the endstops status displayed. Test that they show as at high stop or low stop as appropriate when triggered, and not otherwise.



  • I don't see anything that designates locaction. just end sot hit yes/no



  • I see dtive number 0,1,2,3,and so on that don't match what I have.

    Drive 0 endstop is X, 1 is Y, and 2 is Z.



  • m119 reports x at max y at min z at min, just like I have them. machine won't home for another reason, then the switches and there config. most be a homing config issue



  • yes but those drives are remapped x10 y11 z5

    @sjason1377:

    m119 reports x at max y at min z at min, just like I have them. machine won't home for another reason, then the switches and there config. most be a homing config issue

    Is that the report only when the carriages are at their endstops, or all the time, or only when they are not at the endstops?



  • Ok I got x to travel for homing, but didn't stop. y won't even try nor will z.



  • M119 while holding any one of the switches tells me that that switch is hit and show max for x which is correct. min for y and z also correct. The machine tried to home x once and slammed without stopped despite the m119 showing the switch works and config properly. Now trying to run a print, its homes x y together, but stop both falsely reporting the axis it shorted. the homes z not stopping for that one. might I ad no usb connected and pc, duet, drives, everything powered off 1 power supply made for servers. I scoped it for noise. nothing. Just can't figure it out. x travel exceed the y, but your never going be in the same starting place every time you home. I even g92 the thing to set a far race. last time it homed this way it gave y -595. machine size in config is 0 295y

    Please post the contents of your homing files.



  • The information you requested. Switches were just replaced to these, from the makerbot v1.2 to eliminate all possible failure modes. these are normally closed with no resistor. com and nc connected to outside pins of endstop connectors. individually tested. x drive 10 max endstop. m119 reports x at max when i hold switch triggered. x not stopped when I release. y at min triggered. y not stop when not triggered. Z at min triggered and z not stopped when not triggered. Machine properties console concurs with these results.

    Suggestions:

    1. You are using external drivers for X and Y, but you have M350 X128 Y128. You should set X and Y to 16 in that M350 command, even if you are actually using higher microstepping on your external drivers. I'm not sure that using X128 Y128 in M350 will cause a problem, but it might. Leave your M92 steps/mm at 800 if that is correct for the microstep setting on your drivers.

    2. What types of external drivers are you using for X and Y? You may need to extend the pulse width to more than 2us. Try T4 in your M569 P10 and M569 P11 commands until everything is working.

    3. I suggest you test basic motion first. Send G91 to put the printer into relative coordinate mode. Then send these commands and check that the movement is as expected:

    G1 S2 X50 F3000 ; should move the head 50mm in the +X direction
    G1 S2 X-50 F3000 ; should move the head 50mm in the -X direction
    G1 S2 Y50 F3000 ; should move the head 50mm in the +Y direction
    G1 S2 Y-50 F3000 ; should move the head 50mm in the -Y direction

  • As I stated before, I am requesting answers in the most efficient manner to correct my issues. This benefits both of us. I have 2 years backround in cnc millturn 5 axis setup and control. I already calibrated the machine, once movement happened, by placing it on my mill and following the mills with a feed sensitive probe in spindle. The board produces exact move as advertised. The issue with 128 micro in M350 command much be that way. Otherwise I get 1/8 the travel distance. I know my setup well. this is the 3rd printer board I've tried. Smoothieboard lacked the drive flexibility. Arduino, well you no there limits. I like the Gcode on the fly. Printer worked with 3 other boards. The drivers are kl 5056d they come with software and serial port comm to pc for tuning and calibration. Nothing on my side is causing any of this action. My question is this. Regardless if i am right or wrong, asking someone to look at the files and confirm or direct me is actually a separate request than Diagnosing the total build. I just want to know that my config.g and homing files are in correct. I can play tag for weeks over hardware and calibration, but if it's in the files causing the issue, how many times am I going to check what I know already works. Please understand I total get the switches electrically, mechanically and the moves are spot on. It stops sometimes. Homes 1 axis correct, than doesn't other times. but never all 3 completely as a homeall.g or 1 after the next. I'm not even going to test probing until it's reliable first. To answer the request, I get 6.24903 reading from uccnc off the mill, and 6.25 on duet. again sensor to sensor spindle to nozzle test.

    If I could just receive conformation that I have properly configured those homing files and that config.g is in order as it relates to homing of axis plains I would be very grateful. If I need to correct them I will receive any advice with much thanks!

    No, you haven't. There is an inconsistency between the homing of Y in homeall.g and the homey.g file (clue - the homeall.g looks wrong). Also, if it were me, I'd home Z at the centre of the bed rather than 50mm from a corner but you seem to have far more experience than me so I'll not argue.



  • Ok I tested machine with on board drivers and it homed. This board doesn't work with x y z on external drivers like advertised

    The Duet does work with external drivers for XYZ. However, the drive voltage available on the CONN_LCD connector is 3.3V, and your external drivers may require 5V.



  • what does that have to do with machine not stopping for the endstop switches? this post is about homing not drivers. It want home and you still haven't commented on the files I up loaded. I hit the home x button and slam. Hit home y and slam. S1 is is write in the file. I see the led go out everytime for the axes homing, but slam and stripping the belt. Please just tell me why that is?

    ; Course home X and Y
    G1 X290 Y-290 F750 S1

    ; Move away from the endstops
    G1 X-10 Y-10 F1000

    ; Fine home X and Y
    G1 X290 Y-290 F250 S1

    This is wrong if your Y endstop is a minimum one then you are moving negative 290, then trying to move negative 10 it should be +10. As deckingman pointed out this is different in homeall.g from homey.g so you will get a different result depending on how you call homing.

    Also you have a very different homeZ from homeall.g I would get the individual axes working homing by them selves, then copy those elements into the homeall.g

    I have already commented on your files: i pointed out that using M350 to set microstepping on external drivers might be problematic. Ian and Tony have pointed out issues with your homing files.

    Another issue I can see with your config.g file is that the maximum speed you have configured in the M203 command is much too high to be achievable, especially in view of your high steps/mm. But that shouldn't affect homing because the commanded speeds are much lower.

    Please provide a link to the datasheet for the external drivers you are using, and tell us how you have connected them to the Duet.
