I had a similar issue when the heater slipped halfway out of its place: the hotend was unable to reach the 200 C while half of the heater cartridge ran horribly hot. I don't feel safe leaving the printer working unattended, leaving alone construction mistakes, a single driver failure can become a fire hazard. I would welcome an hot end design including (physical) thermal cutoff for both the hotby ellipse - Ormerod
@zpl: I didn't even noticed that the extruder channel provides an endstop input, I can't wait for the next firmware releases! @dc42: The PanelDue is great, the cheap and dirty buzzer hack connected to fan otuput also works. In my case, the machine is making 100 replicas of the same piece. No screens or pcs on the production line, config.g starts automatically at power on. Operator trainig is liby ellipse - Ormerod
I would like to insert G-codes in a print file in order to have the printer stop, reclaim human attention sounding a buzzer, and wait until a phisical button is pressed. Right now, I've connected a buzzer to FAN0 output and used M106/M107 for playing it. Is there a simple way to connect a pushbutton to a free Duet input and have the printer wait for a keypress before continuing? BTW, I thinkby ellipse - Ormerod
Just upgraded to 1.09a-dc42 from 0.78y, everything works fine except I'm unable to get a mechanical z-endstop working. The led on the Duet confirms the switch is connected and operating normally (the led goes off triggering the switch).

Today my Ormerod.1 (official kit of january 2014) stopped printing because one of the Y-carriage linear bearing locked. It was almost impossible to move, I had to pull it very firmly to unlock it. After inspection, both bearing seals were broken into small pieces, and some of them ended up inside the inner ball guides. Since both seals are broken, I wonder if the defect can be caused by the lubby ellipse - Ormerod
It works! Kudos to @appjaws1 for spotting it first: the M561 was key. I didn't spot it earlier because I was doing M561 the wrong way, that is right before the G32 command (bed compensation). But later I discovered that M561 needs to be executed before G30, otherwise the compensation transform will accumulate the Z-offset set by G30, This is what happens clearing the bed transform after G30by ellipse - Ormerod
Thank you @dc42, 30000 writes is good, I grossly underestimated it. Actually ballprobing.g calls G31 three times (zeroing on ball stand, zeroing on glass, restoring zeroing with optical sensor), so the calculation gives 9 years which is still plenty for me (unless I start printing cheese and zeroing on crackers, I mean!)

Thank you, I have just tried M561 but it didn't solve the isuue. After studying Dc42 sources, I think a change to the value of Z_DIVE is in order. Currently I'm trying to setup the Eclipse environment to recompile from the sources. If nothing else, I would be able to disable Flash writes, as I'm concerned about wearing out the memory, as each bed compensation repeatedly changes the Z-stop offsetby ellipse - Ormerod
Thank you all, community appreciation is what keeps open source running! @dc42: My switch requires a good 100 grams pressure to flip, therefore I'm using three-point compensation probing right on bed supports to minimize flex (video) @jstck: Good point! Luckily x-axis has enough extra travel space on its right side to prevent the ball hitting the x-carriage or being picked up by accident. I thiby ellipse - Ormerod
I have built a mechanical z-probe based on a magnetically-retained steel ball and a limit switch. In my setup, the probe coexists with the original z-probe, and it is put into action when required running the attached G-code. In short, the G-code changes probe type from optical to switch, temporarly adjusts z-probing offsets for the ARball probe, does the compensation, and finally restores settiby ellipse - Ormerod
Dario, I like your clothespin tensioner! Looks like an easy way to ensure proper belt tension, how is it actually performing?by ellipse - Ormerod
Apparently, PLA is more rigid than acrylic: Young's modulus for PLA or ABS is 3.5 GPa, Perspex is 3.2. I'm no expert in construction physics, but from what I understand from Wikipedia, the higher the modulus, the better the rigidity (by comparison, rubber Young's module is less than 0.1 and Graphene is more than 1000). Even better, a printed part can optimize the shape, which determines in largby ellipse - Ormerod
Did you consider printing the whole X-axis? I understand it's a lot of plastic and printing time to get rid of some lasercut acrylic, but it's also a lot of new possibilities: fancy axis structure designs to experiment with, integrated air duct to convey air from a static fan, integrated tubing guides for the extruder or even the gears...

I'm asking here instead of Reprappro directly because I think the answer may be useful to others: I would like to buid a second hot end with .3 mm nozzle. Are the parts available as a kit? Alternatively, is it advisable to start from the Mendel hot kit? (available here: reprappro's Mendel hotend kit) As far as I know, all parts are the same, except the fan is bigger on the Ormerod and the insuby ellipse - Ormerod
Quotedmould "It's the nature of the beast that you cannot rely on every layer being completely filled" Good point, perfect filling is a bit ahead of its times, I can't wait to see the next generation of printers! My mind comes back to the dot-matrix printers times, before the laser+inkjet era (and hey guys, if advances will keep a similar pace, the years to come will be truly amazing!)by ellipse - Ormerod
What is aesthetics for some is function for others; if I were to print a device meant to be watertight, it would make sense to have a warning that some surface is not completely filled.by ellipse - Ormerod
I'm pretty sure that there is plenty of industrial goods whose dimensions are intrinsically precise because of the way they are manufactured (injection plastics, metalworking...) Finding a good-enough cube, a trusted straight edge, and something that can be used as a set square with a flat surface would be incredibly useful for makers.
