Hi rodvaN First, you contacted RepRapPro support to see if we could do remote support through 'Team Viewer'. We just don't do support that way. Also, the way you say it, it sounds like I refused to support you, but that is not true! We have sent you some parts, but I also didn't know that you didn't receive everything you needed. You asked about updating the firmware, and I sent you a link to thby droftarts - Ormerod
Hi Cua193 I was just answering your email, when I saw you had posted here again. Unfortunately, we've been very busy, and coupled with staff absence and holidays, we're a little behind. I'm working to get back on top of the situation. Building, running, maintaining and getting the best out of a reprap can be a frustrating experience; it takes a range of skills, and it's a rare person that has aby droftarts - Ormerod
It should be a pretty scalable design, within limits, though obviously the bigger you make it, the greater the chance of flexing components. All the black parts of the printer are lasercut acrylic (it's flatter than plywood), and very effectively hold the frame square, and it's quite surprisingly solid. The Duet is mounted underneath, between the motors. There may be a problem adding the heatedby droftarts - Fisher
Some details here: The new printer is called the 'Fisher', and named, I think, after Ronald Fisher ( ), continuing the theme of names related to evolutionary biologists (Darwin, Mendel, Huxley, Ormerod). It's designed as a small, cheap, 'starter' 3D printer, though it will still be pretty capable. It is single nozzle (not much space for more), and at present has no heated bed.

Quotedc42Nice of you to credit me with some of the code in 1.09, even if only in a negative context! I put a lot of work into RepRapFirnware, much of which made its way into 1.09 via zpl's fork (i.e. most of the changes listed at that I don't attribute to zpl or RRP), but the 1.09 announcement at doesn't mention my contribution at all.

I've had a couple of customers report heater timeout issues, since firmware 1.09. I think Christian rolled in dc42's PID changes with that firmware. The feedback I've had usually points to a heater cartridge that has a bit higher resistance than normal; one customer that was experiencing heater timeouts had a heater cartridge resistance of around 5 ohms.

Search Amazon for '12V 30A LED power supply'; I generally prefer the PSUs like this: They are made from much thicker metal, and are much more robust, have a fan, as well as being 30A. It's what I use at home. The old Mendel 12V PSUs were cheap. I've constantly asked for a better PSU, but it was RS Component's compliance department that finally caused the change - our old PSU used leaded solder,by droftarts - Ormerod
The easiest thing to do is to use the old version of Arduino IDE v1.6.1 (from ). Since 1.6.2 Arduino changed how they supplied the extra 'boards' for the other architectures they now produce. See If you want to use Arduino 1.6.2 or later, install it, then install support for the 'Arduino SAM-based boards' (like the Due and Duet) by going to Tools > Board > Boards Manager.

A further improvement would be to flatten the point, and bridge across at the top of the circle, like dmould suggests, but a bit more elegant - sorry, Dave! overhang_angle = 45; circle_dia = 10; difference () { cube (); translate () rotate ([90,0,180]) teardrop (circle_dia, circle_dia+2, overhang_angle); } module teardrop (dia, length, angle) { linear_extrude(height = lengthby droftarts - Ormerod
On the subject of horizontal holes, and dealing with an overhang, the other option is to go up at an angle to a point. It's what the original reprap logo is supposed to show, rather than a 'drop' of melted filament, as is often assumed! Here's a quick OpenSCAD script, which lets you play with the overhang value. overhang_angle = 45; circle_dia = 10; difference () { cube (); translate (by droftarts - Ormerod
Hi Fpex Is this the LED power supplies that we supply? We now supply a much better quality 12V PSU (see the two different PSUs we have supplied with Ormerod 2 here ). The older one was usually okay (though it didn't like input voltage spikes much), but if the case got bent, the contacts on the back of the board could potentially short out. The new PSU is much more robust. The problem with usinby droftarts - Ormerod
Hi Ralph There's a Mac-specific firmware update problem thread (with more explanation, and tests) here: Please post your Mac connections problems there. At the moment, it generally seems Macs can see the Duet when it has firmware, but some can't when the firmware is erased. I really don't know why this is! If you can post your experience on the above thread, it may help resolve this problem. Iby droftarts - Ormerod
Hi all Thanks for spotting this. I've updated the Duet Shield wiring diagram so the extruders are correctly marked, made the wiring connections and board legends a little clearer (though they are not what is on the actual board, so I'll update it again at some point). Also turned it up the right way for Ormerod 2, Huxley Duo and Mendel 3 owners, at least! Hopefully it's a bit clearer... Link:by droftarts - Ormerod
Quotedc42 Please note that the pneumatic connectors lose their grip after you have removed and replaced the Bowden tube several times. So get plenty of spare connectors, and only remove the Bowden tube from the connector when you have to. That's pretty much the reason we don't use them. We did have them on the original Huxley printer (over 4 years ago...) but found they eventually pop out, too! Wby droftarts - Ormerod
Quoterjmusto Hi Guys, I am using a 32 bit Mac with OSX 10.6.8 and have Arduino 1.0.6 installed. I have drilled down the folder structure but can see no sign of bossac. In the /hardware/tools directory there is only another folder called avr. I have read further up about using Board Manager to add bossac, but can not see this in any of the menus on my set-up. Any advice much appreciated. Ralpby droftarts - Ormerod
It's still going to be backlash, just a small amount. Check the pulleys on the motors! Ian RepRapPro tech supportby droftarts - Ormerod
Hi krolco Thanks for replying, I was trying to remember who it was! I was talking to zombiepantslol about this at the end of last week, but we can't seem to replicate the problem. I've just done a fresh install of OS X 10.10.3 on a Macbook Pro 6,2 (Mid 2010). With the 1.09 firmware on the Duet, OS X sees it in the System information as: Composite Device: Product ID: 0x003e Vendor ID: 0x234by droftarts - Ormerod
Hi Sven As dmould already said: check the pulley (I think the Y axis belt pulley) is tight on the motor shaft. The grub screw may not be tight, and it's allowing a small amount of 'backlash'. Alternatively, look at this troubleshooting guide: The section before, and section after, can also be useful.

Dave - neat! Thanks for the ideas! Ian RepRapPro tech supportby droftarts - Ormerod
Quotedc42That's how firmware updating is normally done on the Smoothieboard. I think Smoothieboard uses mBed, and that's quite a standard way of updating? It helps to have the in-house ARM devs behind you! Ian RepRapPro tech supportby droftarts - Ormerod
Hi Dave Yes, we've considered this. The main problem is that you effectively need two firmwares. The initial one (or extended bootloader) that runs at startup, that can access the SD card (or network) and compare the installed firmware to the firmware on the SD card (or online), and which can overwrite the flash memory (without overwriting itself), tell you what it's doing (by the serial consoleby droftarts - Ormerod
Hi dc42 They've only changed the location of bossac once... It's just taken a while to find it in the new version! Though they have made it more obscure in the new Arduino IDE version. The commissioning instructions currently say to use the older v1.6.1 of Arduino IDE, so all the firmware updating instructions are still the same. We are looking at other ways to update the firmware.

Hi all Mac users I've had a couple of users report that, while they are able to connect to the Duet with their Mac when it has firmware installed, via Arduino IDE and/or Pronterface, as soon as they press the 'erase' and 'reset' buttons on the Duet, they can no longer connect to it. It disappears off the list of USB devices (System Information > USB ), can't be found by bossac, and will not rby droftarts - Ormerod
Hi Will The update to the original Huxley, the Huxley Duo has only recently been released, and we plan to produce and support it for a long time. We're working to integrate the commissioning for all Duet-based printers into one section, so it's easier to update - I have been updating 4 sections (Ormerod 1, Ormerod 2, Huxley Duo and Mendel 3), and they are getting out of step with each other.

Hi KennethY89 From those results, I'd say the Melzi is okay, and it's still a wiring issue. If the resistors connected to the Melzi are reporting the correct temperature for their resistance values (and I would say they are), either you've got the wrong value thermistor, or you've still got a break in you wiring. Remove the thermistor wires from the Melzi, and measure the resistance across the wby droftarts - Huxley
As dc42 points out, it's a bug in the firmware. I, too, thought it had been fixed (another bug had been), but evidently not. My workaround should also work. We've fixed it in the firmware version, v1.09, that's currently in the test branch, and being tested! Should be released early next week. Ian RepRapPro tech supportby droftarts - Reprappers
Hi Bart Sorry you're having problems with the G32 bed compensation. First off, it's probably best to report problems in the Ormerod forum; most Ormerod owners (and other people running Duet boards) tend to use that forum, and you're more like to get a reply here: Do you have any bed or orthogonal compensation already applied? ie, is this after running G32 for the first time after a reset (rathby droftarts - Reprappers
No, I think it's just a wiring issue. You can test the Melzi's temperature response by putting a known-value resistor (values between 1k and 100k ohm should give sensible readings) in the thermistor screw terminals. This is explained better, and a list of temperatures you should see, in the troubleshooting guide I linked in my first reply. Ian RepRapPro tech supportby droftarts - Huxley
