Hi all, The computer I use to control my Ormerod 2 has suddenly lost the capability to connect to the web interface! What did I break and how can I unbreak it? More detail below. Very occasionally during a print, the web interface would lose its connection to the printer and the only way to restore it was to wait until the print completed or power cycle the printer, which would obviously interrby bartdietrich - Ormerod
Shameless plug but here goes anyway. So I've designed a heat sink enclosure and nozzle cooling duct for Ormerod 2 with quick-set dual nozzles and dc42's sensor board. It's here. It's got a little shutter which can divert airflow to either the nozzle ducts (for PLA) or upwards (for ABS). I am aware that there's a multitude of various designs for hot end bits out there. I thought I'd add to the nuby bartdietrich - Ormerod
As achaz said, you might be able to resurrect the bed by attaching wire links from the underside to the top pads. If you have a Dremel-like rotary tool and one of those wirebrush attachments, maybe you could remove the charred residues from the metal pads (taking care not to obliterate the LED, resistors, or any copper tracks!) to allow soldering the wire links to them?

Hi David, Quotedc42 1. Poor connection at one end of the wire feeding +3.3V to the 4 pin connector; Nope, I get 3.3 V both at the wires where they enter the header socket and at the soldered connections on the back of the board.

Hi all/dc42 (mostly), I have one of dc42's sensor boards installed and today the hot end fan decided to be always on, even with the nozzles cold. It starts up as soon as the printer is switched on. The nozzle temperatures are reported correctly in the web interface, they heat up OK, and the z probe works fine too. The printer prints fine too, in fact so far as I can see, the only thing that's chby bartdietrich - Ormerod

Actually, just had another think about this and you could do it the following way: sections=4; // number of cylindrical sections heights=[3,5,3,2]; // heights of consecutive sections diameters=[5,2,8,7]; // diameters of consecutive sections module draw_section (iter=sections) { cylinder (h=heights,d=diameters); if (iter>1) translate ([0,0,heights]) draw_section (iter-1); }by bartdietrich - Ormerod

QuoteTMD_RS436 Well I still haven been told how much current that the Head Bed or Hot End takes.

I was going to suggest soaking it in DCM or chloroform. The PTFE should be fine, not many things touch it at all, especially not common organic solvents (see here). The problem might be if you have carbonized residue in the nozzle (if you *really* overcooked it). That won't come off with anything that won't also attack the nozzle itself. In that case, sonication in DCM/chloroform might help disloby bartdietrich - Ormerod

You shouldn't need to. G30 will probe at the coordinates specified in its command line. If you don't specify coordinates (but include a P value), it probes at the current position. Bartby bartdietrich - Ormerod
Hi Darathy, The G30 bit sounds about right. From what I can see in reprap.org, the M557 command does not take the H parameter so it looks like you have to use G30. Why do you not want to use bed.g? Bartby bartdietrich - Ormerod
Hi Darathy, If the IR probe triggers at different heights depending on where on the bed it probes, it can be compensated by using the H parameter in the G30 command. See reprap.org Cheers, Bartby bartdietrich - Ormerod
Quotedmould I'd also suggest getting a triangular aluminium bed support, which allows you to set a level bed that rarely needs readjusting. It is not necessary to use borosilicate glass - normal float glass is perfectly adequate. Or do as I did and use a thick aluminium plate.

Hi Fpex, I had a similar problem, not a total loss, but one of the contacts was getting extremely hot, to the point of singeing the Kapton tape covering it and some of the board.

Hi all, Apologies for the delay in responding but work got in the way. Also, the following took a bit of time to do. Following all the replies here, I was a bit concerned about ruining my Duet, or at least hastening its demise if I use it with the ramped-up power supply voltage. In particular, dc42's message about the 7805 overheating, dropping its output voltage and leading to other bits failinby bartdietrich - Ormerod
I know how 78xx voltage regulators work, thank you. My point (perhaps not expressed too well in my last post) was that a sensible design would not call for the regulator to operate right at the limit of what it can handle and would include a safety margin. So by increasing the voltage by a mere 10% I would hopefully still be within what the regulator can safely dissipate as heat. And as you say,by bartdietrich - Ormerod
Hi all, So as promised (or threatened), here's an update. I increased the power supply voltage to 13.5V and I can now get to 125 deg C (although it still takes 20 or so minutes without covering the bed). The ABS temperature (I use 105 deg C, only recently diversified into ABS from PLA, if anyone thinks I should be using 110 instead then please tell me) is reached in 10-15 minutes.
