The Ethernet files on github are for the Ethernet module, I have updated the wiki page to make that clearer.

If you have a look here:

You will see that the Wifi/Ethernet modules are mounted on the Duet main board.

The Duet 0.8.5 is an older design.

Got it, thanks.

Then I will use 2 on the Y/U axis, 1 on the X axis, and I'll use the IR probe on the Z axis.

For the Z axis, I'll home in the center, use the M584 trick to split the Z axis into 4 channels.

Then move the Z probe over 4 corners, and re-home each corner.

M584 to join the 4 steppers into Z axis again, and home in center to set Z height.

Yes to all! Thanks. And after tuning it is not an issue. Thanks

I found the problem 🙂
I've used "M570 S999" command in config.sys, but this command is only valid for ver 1.14 or earlier.
The first attempts the printer was stopped because the heater temperature drops more than 10 C.
Later attempts failed, with increased M570 P and T parameters, because the printer time out after 999 seconds (with unspecified heater…:-O ).
The strange thing now is the heater temperature are stable close to 250 C when I'm printer ABS.... but I don't care to found the main reason or faults behind the earlier temperate drops, because the printer works perfect now 🙂
Thanks DC42 !

It looks like it could be an overextrusion issue. I would calibrate the extruder and maybe up your motor currents if you hear or see the xy motors skipping. Zwobble is also another likely problem. I would look up your printer and z wobble fixes and check them out.

Hope this helps

Looks like there is an issue with the bed temp channel. Please contact your supplier.

@NoSkillzEngineer:

Hmm sooo would I destroy something if it was….hypothetically....on 5V for a couple seconds....or minutes?

Possibly, the touch driver chip on the panel is rated at 3.6V absolute maximum. Although I've heard of a user getting away with running a 3.3V display with the jumper set to 5V before. In any event, it sounds to me that the touch panel or touch driver chip on the TFT panel is faulty.

I've no idea if that would work. We did make a few Duet WiFi prototypes using ESP-07 WiFi modules which have an antenna socket.

Must be gremlins…..seems to suddenly be working!

Ok, thank you for all the assistance, both in my case here, and for all the great assistance you all have provided for others. It is greatly appreciated

@DjDemonD:

I am still getting what appear to be uncommanded tool changes happening despite removing any T commands from my gcode, which is making printing with one material (using my second extruder) difficult to say the least.

For compatibility with slicers that don't handle tool switching properly, an M109 command with a T parameter will cause a switch to that tool in recent versions of RRF. So check your gcode for M109 commands.

Many thanks David, all working,
Mike

@r0n_dL:

Also making the assumption the more important mesh leveling using the stock probe and heatbed with the embedded 9 detection points are supported.

Yes you can define a probing mesh that lines up with the existing probe points if you need to probe at only those points. I guess the i3 has a bed with varying inductance so it might make sense to probe at only those points I suppose.

@Texzin:

The Folger Tech FT-5 has 2z , 2y, 1x. So if I just use the Duetwifi with out the Duex2/5 I will have to connect the Y steppers in series. Can I series the Y steppers without causing problems or should I add the Duex2/5?
Can the E1 be mapped to run second y steppers?

My config above is for a FT5 Z is on the Z port (both connectors).

Thanks

Yes, that works in recent firmware versions.

think i got a bat43 diode but might have been a 1N4148 cant remember right now what one radio shack had in stock at the time and its heat shrinked at the time

A flat piezo element used in the same manner as a foil strain gauge element certainly sounds lie it is worth trying. I would think that most places that you could put a single element on a PCB effector would have differing sensitivities in the X and Y planes but that would not be likely to have any effect on a straightforward Z probing operation. Thermal effects may be more of a problem but they can probably be worked around as they are with piezo diaphragms.

Another one that may be worth looking at are thickness mode piezo rings such as this one from Steiner and Martins https://www.steminc.com/en/piezo-ring-18x12x12mm-18-mhz-2-wl At $5 per ring they are a lot more than diaphragms but still not very pricey.

Mike.

p.s., I am the Mike that DjDemonD mentioned a few postings ago. I haven't yet got to 1 gram having hit the wall at 5 grams but will try again over the next few days.

The stepper motors used are always well below the VIN voltage 1.4V is fine. The stepper drivers limit the the current flowing through the motors.
