The images were clicked by our phone and computer I don't know why it shows this message

No, I still can't see the images. This is a common problem with photobucket, I think you need to have a paid-for account for other people to see them.

PS - if you want to use Dropbox to host your images, replace ?dl=0 at the end of the Dropbox URL by ?raw=1.

JGR

Is it possible to send you the image through email

dc42

Please host them on imgur or dropbox. See https://www.csoonline.com/article/3205765/internet/photobucket-replaced-millions-of-images-with-ransom-demand.html for more about the photobucket issue.

JGR

Thanks for the advice will do it.

Also please post your homedelta.g file here as text, as you did with your config.g file.

Thanks, I can see those images.

1. Homing failed: I still need to see the contents of your homedelta.g file.

2. Heating fault (temperature rising too slowly): see my reply yesterday, https://www.duet3d.com/forum/thread.php?pid=44742#p44742.

homing problem is solved the homing file had everything commented
Thanks

The z probe always shows at min stop. The threshold value is shows 1000 and when triggered it shows 165 how to reverse this one ?

@JGR:

Add parameter I1 in your M558 command. That's letter-i followed by digit-1. Better still, use the NC conrtacts of your switch instead of the NO contacts, which is safer if the switch becomes disconnected.

JGR

yes it solved the problem. Is it ok if we use 31865 board for PT 100 sensor with a reference resistance of 430ohms. I have read the instructions where it says use 400ohms Ref resister. we also have a Resister 391 ohms but have to replace that one on the board. we have also order the daughter board but it will take 2-3 week to reach our office. Is it possible to use 31865 board as we currently have in stock.

dc42

To use a PT100 board with a 430 ohm reference resistor, use parameter R430 in the M305 command that configures the heater to use that PT100 channel.

All the heaters are fluctuating more or less 5C even after auto tuning. The Chamber behaves a little wired sometime it gives the temperature rise error and some time it doesn't. please guide us through right procedure.

Also during bed levelling, While clicking at the UI Autobedlevel button it will take all the points correctly , but if we give the g32 command the head will move outside the bed size to take the points.

bed.gcode

; Auto calibration routine for an example delta printers
; Before running this, you should have set up your zprobe Z offset to suit your build, in the G31 command in config.g.
;you should use https://configurator.reprapfirmware.org/ to setup a correct bed.g file for your printer, what is below is just an example (and its commented out)

M117 Use https://configurator.reprapfirmware.org/ to set up your printer config

M561 ; clear any bed transform, otherwise homing may be at the wrong height
G31 X0 Y0 ; don't want any probe offset for this

;*** Remove the following line if your Z probe does not need to be deployed
;M98 Pdeployprobe.g ; deploy the mechanical Z probe

; The first time the mechanical probe is used after deployment, it gives slightly different results.
; So do an extra dummy probe here. The value stored gets overwritten later. You can remove this if you use an IR probe.

Please use the configurator to generate a new bed.g file. Also if there are deployprobe.g and retractprobe.g files in /sys on the SD card that you didn't create yourself, delete them.

The heaters shouldn't normally oscillate if you tuned them correctly and saved the M307 parameters to configure.g, however if the do then increasing the D parameter in the M307 command should cure that.
