running a 12v heater at 24 volts actually quadruples the heating power so be very careful the general advise is to spend a small amount and get a 24V Heater cartridge there not that expensive and will be a damned site safer

@Sindarius Just loaded it up and what I see looks sort of OK think you also need to check the Config.g to decide on the type of printer it automatically seems to default to a Rectangular bed with the origin at 0 0.

I the case of a delta the origin is still 0,0 but is in the centre of a circular bed.

I you check the config.g for a M665/M666 lines and set it to circular centre origin it would be pretty damned good?

As far as I can tell your M140 (line 75) should come after the corresponding M950 (line 85)

"Order dependency

In RRF3 a M140 command with H parameter (other than H-1) must come after the M950 command that creates that heater, and before any M143 command that sets a temperature limit for that heater."

@moowcowsia don't use solid core cable with all the movement the cores will work harden and fracture and that is probably what is causing your issue. You can get stranded cat5/6 cables usually as a patch cable rather than on a drum but should be easy to find and then to crimp as normal.

Any computer store should have them and if it is soft and flexible then it will be stranded but if stiffer then its will be solid.

@autsch Chris Hamm has released a new version of DWC which may have fixed this error see

@diy-o-sphere said in Tool Board Heater Tuning Leading To Faults:

@fcwilt
Not required for PT1000 on Duet3 and Maestro

nor on a wifi/ethernet duet 2 board either just not quite as accurate due to the 4k7 sense resistor rather than the 2k2 one

the G30 P8 line in your Bed.g is missing a decimal point on the H parameter causing it to think the offset at that point is huge (192mm)also I notice in your M563 line you have the dive hight set to 1mm maybe increase this as well.

Maybe that is what is causing it too fail?

@snowcrash here you go I do need to locate a slightly smaller bearing and make a spacer up for between the bearing and the coupling the one shown is a 10mm bore one and I am looking for a 6 or 8 mm one the reason for the over size is I dont want the bottom race to be in contact with the shaft at all.

@tlas IIRC the Wifi version has a separate antenna so a metal box shouldn't be an issue https://shop.pimoroni.com/products/raspberry-pi-compute-module-4-antenna-kit

Very Shouty Post please edit it no-one is going to read it has it is very hard to read something in all caps

or you could use a FanShim works extremely well and doesn't interfere with the expansion header

@as-3d-druck said in My custom D-Bot:

You're D-Bot looks way cleaner than my.
Is the 3 Leadscrew System woth it?
I got 2 with a BLTouch as a probe and i'am not shure if the 2 Leadscrews are not good enough or the Z Probe is crap.

the advantage with 3 is that then defines a plane so when setup correctly the bed must always be level when you have just 2 then that is a pivot point.

@dc42 Thats sounds interesting If you see this Chris can you elaborate a little more?

Doug

I also run them on my Delta and they are fine.

Doug

(I think DC uses them as well or possibly the 1684 ones which are just a slightly lower current version depends what OMC's uk warehouse have in stock at the time which reminds me I need to order a pair of them.)

Pimoroni Have stock and if you do get from them checkout there Fan-Shim for it.

Think he wants to Download his files as a backup Ian

@giostark can you post the code file you are trying to print

@dave-poltorak I actually wonder if the IAP file is for later FW I can't remember when that was changed but you could copy the FW File (Correctly named) to the sys folder and then issue a M997 S1 I think it is. Yes just checked it is S1

The file needs to be named DuetWiFiServer.bin

HTH this goes back so far i may be slightly off but I don't think so

@djdemond said in Might have finally killed a DuetWifi:

I am going to try as an alternative to network cable 13 core towing-electrics cable. It has the following wire sizes within it

7 x 0.65mm2 1 x 1.5mm2 and 4 x 2.5mm2

Which should provide 7x 2 amps, 1x 10amps and 4x 20 amps of current handling, with I am sure much tougher insulation. £5/meter.

The only drawback is I suspect it will be rather heavy compared to 2x cat 5 network cables.

Simon

Why not look to using silicon covered wire and make your own bundle and then just encase it all in braid 13 core trailer wire is heavy Thick and very Stiff.

Got all mine from Hobbyking

Silicon Wire

I would suggest 20awg for hot end power (at 24 Volts or 18 at 12) and 26 for all signal cables
