Quote3D-ES @dc42 Have you seen this message, and does it contain the information that you need? I've seen that, but that example doesn't freeze when using 0.57a firmware.by dc42 - Ormerod
QuoteKimBrown Thank you 3D, yes I had set 'wipe on retract' for that print... I've turned it off now, so that will be the reason for the freeze. If you or anyone else can come up with a small wipe-on-retract example that always freezes using 0.57a firmware, then I'll take a look at the firmware. I've already seen some possible candidates for where the problem may be.by dc42 - Ormerod
I often get a blobby first layer on the first print attempt of the day. It gets better after a few attempts. Next time I will try extruding 100mm or more of filament first.by dc42 - Ormerod
Which operating system are you using, and which firmware version? Does the bed continue to heat up, or has the Duet reset itself?by dc42 - Ormerod
I find it very difficult to apply the Kapton tape (partly because my eyesight is not as good as when I was younger). I always get gaps, or overlaps, or bubbles. On occasion I've started a print with the head to low, and this always catches and lifts the edges of the tape. So even when I have managed to apply the Kapton well, it hasn't lasted long. Currently I'm using Marley KS10 pipe solvent adhby dc42 - Ormerod
This works for me: C:\Arduino-1.5.4\hardware\tools\bossac.exe --port=COM12 -U true -e -w -v -b C:\Users\David\Eclipse\RepRapFirmware\Release\RepRapFirmware.bin -R So I believe the command line given in the instructions is correct. Some suggestions: 1. Are there any other files in C:\Arduino-1.5.4\hardware\tools\ or related directories that bossac might be using, and that you have not copied toby dc42 - Ormerod
QuoteGregL I do have a problem with the Z gears: the rod movement is eccentric at the Z gear, and there is cyclic noise clearly associated with the rotation of the gear. I have also had quite a few inconsistencies when trying the bed levelling - ie go back to the first point to find its Z level has changed. How do I tackle those Z gears? Greg My z-rod was eccentric at the z-driven-gear too, buby dc42 - Ormerod
Kim, I'm sorry to hear you are having problems. The Pronterface patch can only be applied if you use the non-precompiled version. The web interface works quite well if you use the latest firmware and Matt's web interface files, see . As supplied, the z-probe only works well when there little or no direct sunlight or incandescent artificial light. If this is no good for you, use longer screws to lby dc42 - Ormerod

It printed just fine for me, using my standard settings.by dc42 - Ormerod
My settings files were made for slic3r 1.0 RC2. If you load the standard Ormerod settings files in any slic3r 1.0, it warns you that the settings files are old and should be re-made from scratch. So there is some incompatibility between settings files for 1.0 and pre-1.0 slic3r, and I guess the settings files I provided may not work well with slic3r 0.9.9.by dc42 - Ormerod
Paul, which version of slic3r are you using?by dc42 - Ormerod
I think it is better to leave a single bearing at the front and support the bed at just 3 points. The real problem is that the back bearings are some distance from the back corner bed support points, and the MDF isn't stiff and stable enough, so it tends to sag in the back corners. So you can manually level the bed, or use the automatic mechanism to compensate for it not being level, but either wby dc42 - Ormerod

Have you soldered in all 4 of the USB connector mounting tabs, if they weren't already? Easiest done from the back of the board.by dc42 - Ormerod
Sounds like in slic3r you have extruder lengths set to absolute instead of relative.by dc42 - Ormerod
I looked into this before and decided that 3 pieces of 55/0.1 wire in parallel would work well. Total 8 wires in the chain including the thermistor wires.by dc42 - Ormerod
QuoteMickyblueeyes Hi dc42 that was along the lines I was thinking as it was your modified deflector I chose, unfortunately having spent hours modifying it I now realise the new fan has 9 blades, I modified it to take the screws at the bottom but as with anything I do on Sketchup I spent more time repairing the file because of its poor stl import routine. Maybe I need to go back and modify the orby dc42 - Ormerod
Quotedmould Quotedc42 If the Duet is receiving power from USB only, then the stepper motors are not running, and saving the position is not of interest. That depends what order you switched off the machine - 12V first, or unplug USB first ... Dave It doesn't matter, either way the position will be written to flash when the 12V supply is removed. If you want to discuss this further, perhaps yoby dc42 - Ormerod
QuoteGregL Still have the same problem on trying to print the Ormaxis - extruder stutters. Although set at 205, the hot end was mostly around the 201.5 region. Should I: 1. Set the hot end higher still 2. Increase the amps on the extruder motor (if so how?) 3. take the hot end apart and re-assemble Greg PS firmware was and still is 057a If you lift the nozzle well above the bed and heat it to 20by dc42 - Ormerod
QuoteKimBrown I wouldn't be at all surprised if the problem is the fact there is to much 'current' whizzing through the duet board. Actually, only about 50mV is lost in the Duet board, and most of that is in the mosfet. There are much bigger voltage drops in the cables. See and for a breakdown of where the voltage is lost.by dc42 - Ormerod
QuoteMickyblueeyes I tried to add a deflector at the input end but this makes the fan a lot noisier so I need to try a few different designs to cure this, the backwash doesn't seem as bad as the original fan but I cant measure it. The original louvred deflector I tried made the fan noisier, but the one I eventually printed - see - makes the fan quieter I think. I deliberately chose a number ofby dc42 - Ormerod
Quotedmould That's if there is circuitry present to monitor the 12V rail, and the decay is slow enough to reliably complete a write to flash. Also remember that the Duet can be powered from the USB or separate 5V supply instead of the 12V, and those could be removed before the 12V. Yes, it would be necessary to add a voltage divider across C3 and feed the output to a spare analog input, or oneby dc42 - Ormerod
There are a number of threads about ABS printing such as . The most important aspects appear to be: 1. The supplied ATX PSUs provide somewhat less than 12V under the load of the bed heater. The Alpine PSU I received would get the bed up to 120C as reported by pre-0.53 firmware in about half an hour. I have the impression that the Ace PSU is worse.

There is already some support in the firmware for X and Z low-stop microswitches. In particular, the pin numbers for them are already defined: #define LOW_STOP_PINS {11, -1, 60, 31} #define HIGH_STOP_PINS {-1, 28, -1, -1} These are Arduino Due pin numbers, not mcu pin numbers. The internal pullup resistors for these pins are enabled, so you don't need an external one unless noise pickup is a prby dc42 - Ormerod
The delay in responding to a pause command when printing from USB is unfortunate, and is caused by the buffering in the USB subsystem, coupled with the Pronterface patch to get USB printing working properly and SD uploading working at a reasonable speed. I'm thinking of adding a Pause button on top of the Duet enclosure. This would immediately stop the print, raise the head 10mm, and turn off thby dc42 - Ormerod
Can I point out that the slic3r settings I posted are for slic3r 1.0 RC2, and that these settings are probably not compatible with pre-1.0 versions of slic3r, judging by the warning messages you get if you use the standard Ormerod files with this version of slic3r.by dc42 - Ormerod
The problem I see with that approach is that the voltage at the non-ground end of the thermistor is very close to the +3.3V supply voltage at low temperatures. So you really need to have that voltage available to compare it with - and you definitely need it if you want to detect an open-circuit thermistor, which I think is a necessary safety precaution.by dc42 - Ormerod
Quotedmould Besides which, the board does not know when power is about to be removed, and after it is switched off it is too late to store anything! So the duet would have to store all changes continuously just in case it's about to be switched off - and erasing and re-flashing takes too long to do that between every move, besides wearing out the flash. Actually, it would be quite easy to tellby dc42 - Ormerod
