Hi, thanks. I am currently running another print. Its probably user error on my part, but if it stuffs up I wont know why (last print was perfect) so I'll upload the gcode off the printer directly.

@dc42:

1. How are you sending the M587 command? If you are using Pronterface or a similar USB host program, it is probably converting the characters in the password to uppercase.

2. Check that your router encryption is set to WPA2-PSK.

I switched to YAT.

Its set as its set there was no change. WPA2-personal, it looks like the "operating system" become corrupt? at least that is the signs. Now on 1.19.2 the cooling fan now runs OK and I have movement of the 3 axis.

Reading the docs I could see a comment that the duet "chases" the strongest wifi signal? I know in that part of the house the signal is weak and with 6 SSIDs in my house alone its possible that was the problem as when I moved the printer to 2m from the router I got an IP and a connection pretty quickly.

Anyway I am now testing to see what has changes with this firmware have "broken" what.

See https://duet3d.dozuki.com/Wiki/Choosing_a_Z_probe for a comparison.

The cheapest auto level probe is no probe at all. If the bed is flat (e.g. cast aluminium tool plate) and the gantry doesn't sag, this is a realistic option for a Cartesian or CoreXY printer.

The problem with using a switch is that you either have to fit and remove it manually, or have some sort of deployment mechanism to keep it clear of the nozzle when it is not in use.

My delta printer uses a nozzle contact probe, and my Cartesian and SCARA printers use IR sensors. Nozzle contact probes are probably the most accurate, but the IR sensor works sufficiently well with a glass bed as long as you put a matt black surface beneath it and you don't put coatings on the glass. I print PLA directly on to the glass.

I do love that this is now something that people need more and more. The WiFi can do 12, there is another thread on the forum where someone wants 13/14! A few years ago that would be pretty unthinkable!

@gzcwnk:

Ah cool….exactly what I wanted, so an airstream down the middle? say a 5015 centrifugal fan?

http://www.openbuilds.com/media/duet-wifi-duex5.566/

That should be more than adequate.

Does it work when the desktop Mac is switched off?

to prevent this happening again you can use the router to assign a "fixed" address to the duetwifi

@gzcwnk:

Could I see your config.g please?

Here it is but you need to be aware of a couple of things because the printer configuration is probably a bit different to yours.

Basically I use Diamond hot ends which have have multiple inputs (3 or 5) and so I have 5 E3D Titan extruders. Because I wanted to keep the Bowden tubes tubes, the extruders are mounted on their own XY gantry which sits above the hot end gantry. For normal printing, the upper and lower motors are mapped together so as far as the Duet is concerned, it acts like a singly CoreXY with the U and V axes hidden. However, when the printer is turned off, it is possible to move each gantry independently so it would be easy for one to be offset from the other. For that reason, each gantry needs to be homed individually so that they are both correctly positioned in relation to each other. The way it works is that the upper motors are mapped to U and V for homing, then re-mapped to X and Y for printing and the U and V axes are hidden. I've included my homeall.g as well to illustrate.

Oh, and it's a Duet Ethernet, not WiFi.

Also make sure your hotend can handle those temps!

Wow that is way way faster and it gets to 235C without any 5C+ overshoot and minute or 2 to settle like it did before 😄

thanks for your help anyway!

In your slicer end gcode.

Yes sounds like your pause file raises the Z height by 5mm but the resume one is not lowering it again. have a look here:

https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Pause.2C_resume_and_cancel_files

For the extrusion speeds only the 2 slowest will feed without the stepper missing, so I really just want to remove them to make the web ui more usable for the rest of the family, but its no biggee.

@dc42:

I would be concerned about that too. You could mount the leadscrews on thrust bearings, then it would be convenient to use 1:2 gearing to drive them from the motors. Or revert to using belt drive. Or perhaps it is possible to find a thrust bearing/leadscrew combo that lets the leadscrew shaft protrude below the bearing, then you could use a flexible coupler to connect it to the stepper motor.

Thanks dc42….see my comments above concerning support of the Z screws. I am looking forward to your finished work on the 4 Z motor firmware. Thanks to you and all the DuetWifi team.

Thanks will try this evening, but it will be a 31 hour print before I know!
