Machine pauses re-assigns a need axis concordant value than travel which ever way it wants and ignores the switch.
I'm using a scope between the end stop and switch and clear see 0.002 volts when switch is closed and 3.312 when open! My switch are fully holding the connector voltage to zero!I can't make the correction that was suggested early about micro setting, because I did that 3 days ago. Just plain old 16 time no interpolate. Same setting on drive. Next I whole step the thing, but that will fail too.

Thanks for posting your current config.g file.
You are using M584 to select drivers 5 and 6 as the X and Y drivers. M584 does not remap the endstop switch connections that are used, only the drivers. Therefore you still need to connect your X and Y endstop switches to the X and Y endstop connectors on the Duet. Is that where you have them connected? Or have you connected them to endstop connectors on the DueX5 instead?
-
The j33 and j32 connectors are the standard end stop connector that are normally used, center area of main duet board. I only have the simple expansion header board. Instruction state that that end stops are handled the same regardless of external drive config.
-
M569 command line has to be written with actual drive numbers used. So x is drive 5 and y is drive 6 z drive 7 same as M584. Other wise there is no motion. I think there may be an issue with end stop and drives not matching as they should in firmware. Something just isn't right. Do you know of anyone who has actually succeeded at configuring all external drives, or at least x and y? If so, seeing the config and homing files would probably help. I'm pretty sure Mine are according to documentation. There really need to be more info produced about what firmware is actually doing. If it can't perform an operation there needs to be a report as to what element is wrong, missing or at least point us in the right direction. repetier host provide much more internal data. I emailed an entire report from a failed homing attempt. It provided alot of motion data I'm not able to understand, but someone should. There was a reason provided for the failure as well, which I can't understand either. Have you seen that?
This example from Duet site below doesn't help much when it displays the original assignment for all on board motion drives.
We need an example of an actual external drive assignment using a drive number that you can actually use.
X can't remain 0, and Y can't be 1 Z can't be 2 or 3 these are not available for connection as external unless they come off lcd or 50 pin header.
This makes them only available as 5,6,7,8,9,10,11"Example
M584 X0 Y1 Z2:3 E4:5:6 ; Driver 0 controls the X motor, 1 controls Y, 2 and 3 control Z motors, 4 and 5 control E motorsAssigning a drive using M584 does not remove its old assignment. Therefore, if you assign a drive that defaults to being an extruder drive, you should also assign the extruder drives explicitly as in the above example. Failure to do so may result in unexpected behaviour."
Than how do I remove the old assignment? This might be the end stop S1 hang up. Firmware probably can't find the connection between these 2 events. I think firmware needs to see x drive 0 and x end stop for 0. This is contrary to the ability to externally drive a printer with this board. Support needs to be built into firmware to enable end stops that are externally driven for x y z based on M584 reassigned drive numbers. I understand M584 only reassigns the drive portion, but it leave a disconnect as to the usage of an end stop that normally configures to an axis that was originally assigned to 0 or 1. The end stop portion also needs to be reassigned to new drive number. M569 should work, but it doesn't pan out that way because M584 doesn't remove old assignment. This explains why I don't produce motion with S1. Firmware is either trying to drive S1 related motion command from drive number that no long exists or I can't clear axis motion because it can't related x end stop to a non 0 drive number.
-
The endstops are independent of the drive mapping.
I'll put your config.g and homex.g on my bench test system and test it.
-
I've replicated your system as best I can, but I am using a DueX5 to drive three Nema 23 motors because I don't have any external drivers. Here is a video showing X homing behaviour. I have connected a NC push button to the X endstop input, and I press it to simulate the endstop switch being triggered. When I press it, the X endstop LED goes out and the homing move stops as it should.
https://www.dropbox.com/s/otl3gkwt8pkx249/2017-12-11%2011.44.25.mp4?dl=0
I tested with both 1.19.2 and 1.20RC1 firmware versions.
Are you quite certain that you have the X and Y endstop switches plugged into the correct connectors, and not swapped? The order of the endstop connectors is Z Y X E0 E1. In the Machine properties page of DWC, the first row (which starts "Drive 0") shows the X endstop state. Under "Endstop hit" is shows "No" when the endstop switch is connected but not pressed, and "Yes" when I hold the button down.
-
OK now my turn. I'm going to make my own video and show exactly to the best of my ability a visual inspection and demonstration of the behavior. Hope I can figure out how to upload video here in proper resolution.
-
https://www.dropbox.com/s/0e4zo5gx2p2cdnz/00009.MTS?dl=0
Here's my video
-
As you can see I demonstrated switches working. Than I showed a failed S1 attempt. Next you see the x carriage moves under S2. Last you see the x homing behavior. Notice that there is a tiny move in the beginning. Less than a mm. The digital distance readout changes twice. From 70 to -220, than to zero all without moving, or using a homing switch. This clearly displays a board with an ability to run a file in an inappropriate manner. This board is assigning a coordinate without activating a switch. The failure to produce motion is 1 issue, how about confirming a homing run without feed back from it's switch. And what's with the busy sign that takes 30 plus seconds to clear. Something has to be wrong more than user error. If need be I will hook up a meter to show full voltage rise and fall for my switches. Anything else you wanna see let me know, otherwise I got mail this board back. I really would like to sort this out first, because I don't want to get stuck with a refusal to except the return in the long run if it's config related. But firmware bugs are not my fault.
-
Thanks for the video. I will study it in more detail tomorrow. Meanwhile, I think the issue must be to do with the different timings that happen during homing moves because of the extra homing switch checks. Please can you try a fee more things:
1. Does the Y axis behave the same way, i.e. after G91 you can do G1 S2 Y moves, but G1 S1 Y moves don't work, even though the endstop is showing as not triggered?
2. In your M569 commands for the external drivers, change T2 to T5 to lengthen the minimum step pulse width and interval.
3. Try firmware 1.20RC1.
Also please provide a link to the data for the stepper drivers you are using.
The problems you are having are really bugging me too, and I hope we can get them sorted soon.
-
PS - if those tests don't resolve the issue, I thought of another useful test. Let's eliminate the endstop switches from the equation, by disconnecting them from the Duet and changing S1 to S0 in the M574 command, to make the endstops read as not triggered all the time. Then see whether G1 S1 movement commands move the head the distance commanded, just as G1 S2 commands do.
-
The new firmware 1.20RC1 allows x and y to complete homing with nothing changed in any of my files.! Now
i am on left with the bl touch smart 3.3v logic sensor to work and I'll be printing. I wanted to thank Dave, Tony, and the other members for there help with this issue. They say cleanliness is next to Godliness, I now say patients is. Forgive me for some of the comments i made in response to so answers. More patients is in the works.Now I could probably get probing done quit if I could receive a review of all the files pertaining to z homing and whatever feature allows for leveling. My bed is machine cast aluminum plate further flattened using lapping plate diamond slurry. You'd think at 50/1000000's of the inch over the longest distance, That I wouldn't need it. I didn't realize the bed heat and glass cover would ruin my perfectly flat level running bed, but they are terrible in comparison.
Ok so I got M280 P7 S10 to deploy the probe. M280 P7 S90 retracts well also. Solid red light changes blue on deploy. Probe indicator on web interface reads 1000 . This value doesn't change. Sensor doesn't report contact with bed surface.
Probe is wired to the z probe in and gnd pins not the special probe pin. no z homing swith either. I must has missed something in instruction on this thing. Documentation doesn't support rep rap firmware from bl touch's end. What I find from Duet side of things is a case of catch up due to the release of many version of this probe and firmware. This things config setup has changed so many times I'm clueless.
An help will be great, Thank all!

I'm puzzled - I can't think what I changed in 1.20 series firmware that could be making the difference! But I'm glad it's working. I'm sorry it has taken so long to resolve what was evidently a firmware issue.
Regarding your bltouch, there are at least 2 issues here:
1. Your Z probe is not working with the firmware. The Z probe reading should be 0 when the probe is deployed but not triggered. it should go to 1000 (possibly too briefly to see) when the probe is triggered.
To test a Z probe, with the head well above the bed, deploy the probe and send G30. The head should move towards the bed (or vice versa). Trigger the probe by holding something under it. That should stop the movement. If it doesn't, cut the power to prevent the head crashing into the bed.
However if you are getting a Z probe reading of 1000 all the time, that isn't going to work because the G30 command will provoke the message "Error: Z probe already triggered at start of probing move".
Please post a photo showing how you have connected the bltouch to the Z probe connector. Also post the lines you have added to config.g to support the Z probe - you should have at least a M558 command and a G31 command.
2. Your Z homing file is set up to use a microswitch, not a Z probe. To home Z using a Z probe you need to use a G30 command, not a G1 S1 command. See https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Homing_Z_using_a_Z_probe. Your homeall.g file is already set up to home Z using a G30 command.

Questions,
(1) For homez.g I'm no use M280 P7 S10 to deploy G30 to trigger height M280 P7 S90 to retract G92 Z0 to set height. That's working well. Thanks!
(2) Second I see option for M98, G32 G31 for probing multi location. I want a bed.g file that will measure and compensate for rolling variation of flatness with a total of .7 mm of adjustment over 87,000 Sq mm's.
I think the 16 point version might work. However after using the Escher3d cal. I see M or Gcode telling firmware what probing feature it's running. G28 to home x,y M98,M98 will be changed to M280's M98 doesn't work. Than G30 for every measured point line by line or isn't G32 0r G31?
And how do I tell firmware to store and run height values every time only running bed.g every so often to check stored values are still correct?(3) My bed is mounted on thk 15mm rails attached solid cold drawn steel bars 65mm high 20mm wide. Bed is constructed with 12.7 mm thing aluminum plate bolts direct to linear guide way carriage blocks, 3 on each side 50mm long each. machine frame is just as stiff. My bed leveled state will never change outside of thermal variation. So I need a good 1 shot probing run and a repeated use file of the recorded deviation in flat/level.
This is what calulator produced for bed.g

For general bed compensation, you should use G29 mesh probing. See https://duet3d.com/wiki/Using_mesh_bed_compensation. If you are using multiple independently-driven Z leadscrews, you can use G32 and bed.g to adjust them if you wish, see https://duet3d.com/wiki/Bed_levelling_using_multiple_independent_Z_motors. Or you can use G31 and bed.g to tell you the corrections you need to make to your bed levelling screws, see https://duet3d.com/wiki/Using_the_manual_bed_levelling_assistant.
The calculator is for generating probe points for calibrating delta printers.
Normal practice for deploying and retracting the Z probe is to use M401 and M402, not to invoke the deployprobe.g and retractprobe.g files directly with M98. The probe will automatically be deployed before probing and retracted after probing if necessary; however in a bed.g file you may want to use M401 and M402 explicitly so that it only deploys and retracts the probe once, instead of once per probe point.
-
M401 isn't working M280 P7 S10 is what bl touch instructions say to use on deploy and M280 P7 s90 retract. I've seen this written in many examples, but also some users need to ad a T0 in the deploy.g and retract.g but it doesn't work for many of us either. Seem like plain M280 Your P# and S10/90 is what working with this thing. It's providing trigger now. I start at 0 and triggered 1000. So if I run G29 will these result be used to alter the performance of print begining to actual simulate a level surface? Or do these options just for measuring purposes, still requiring manual leveling?
-
1 final question. I use a 5v psu so that I have pwr to m80 the 24 supply. When not using printer, is the correct turn on, off option for the board itself simply to switch off the 5v? Or is there some form of boot it off? Or is it better to just leave the 5v side on forever? Board life span is my main concern not energy. I of coarse disconnect from the interface first.

M401 calls sys/deployprobe.g and M402 calls /sys/retractprobe.g so you need to put the correct M280 commands in those files. But in addition, M401 and M402 remember whether the probe is deployed or retracted, so that the firmware doesn't run those files automatically if the probe is already deployed.
Successful completion of probing after sending G29 S0 or just G29 will cause the height map to be used for subsequent prints until you power off or reset the printer, or cancel compensation by sending M562 or G29 S2. It also saves the height map to a file on the SD card so that you can load it subsequently with G29 S1.
-
It's up to you whether you supply 5V to the board continuously when you are not using it; but I would turn it off. The board uses about 1W of power when it is idle.
