I've kind of gone the opposite way. I got an Ormerod 1 back in March 2014, and used it quite a lot for a few years, constantly modifying / upgrading it, with new printed parts and bought bits. Still, it was always a rather temperamental machine and hard to get it to print well even after all those fixes and upgrades (especially regarding bed levelling and adhesion, largely due to the frame rarelyby jstck - Ormerod
On many other 3D printers (like Mendel and Huxley) there are two steppers for the two separate Z screws. It seems to work alright, and unless you have your machine "crash" (by going too far in either Z direction) you shouldn't have the steppers skip. And in such a situation, you may also have a belt skip. One problem I've experienced with a Huxley was that if you were doing something with the maby jstck - Ormerod
I'm on duet/panel firmware 1.04b / 1.09. I've changed everything "new"and I have gcode files using both tool 0 and 1, and I was able to print both kinds by defining both T0 and T1 (being the same tool, on my single-extruder machine): M563 P0 D0 H1 M563 P1 D0 H1 It seems to work, only downside I can see is that the user interface thinks there are two separate tools.

$ grep -i version src/Configuration.hpp #define VERSION_TEXT "1.09" I got a bit confused by the version being shown as 1.09, but I expect it's easily fixed for next release by just leaving it as it is.by jstck - Ormerod
For one thing, Java has almost nothing to do with JavaScript, except some common root in basic syntax, and the misleading naming similarities. Even so, in a modern environment, neither is anywhere near as slow as 1/10th "native speed" (comparing to compiled C/C++ code), on tasks mainly relying on "raw numbercrunching" you would probably get somewhere around 50-95% the performance (and based on myby jstck - Ormerod
There's also this thing (a remix I made of bobtidey and dc42's enclosures) that mounts on the rear of the printer, similar to the Ormerod 2. Also designed for the Ormerod 1 ATX PSU adapter, but it should be relatively easy to adapt the design.by jstck - Ormerod
QuotedmouldThe calculations are extremely complex, and also need to be fed with & process every line of the G-code. Not really feasible to do in web-based javascript. The complexity would mostly be in duplication of code, as all the code used by the firmware when printing would need to essentially be ported to Javascript and updated whenever the firmware changes (since the actual print timeby jstck - Ormerod
Pretty cool! Does it ever pick up the ball by accident when printing nearby?by jstck - Ormerod
Quotedenshine i say dont buy it! as a starter printer thers to much to do to get it working. i would go for a ulltimaker or something simular. That's not really a fair comparision, as they are very different products. An Ultimaker is a brilliant printer, and it is dead simple to get up and running (if you get a preassembled one), and generally very easy to use. The downside is it is 2-3 timesby jstck - Ormerod
If you can't even ping it, something is probably wrong with your network configuration (the IP settings on the Duet not matching the rest of your network, it is connected on the wrong port of the router, or you did what I did and neglected to put the SD card back in...). The Duet obviously has to connect using a wired ethernet connection (as that's the interface it has), but I don't think I haveby jstck - Ormerod
It would probably work having a printed piece (or 2-3 parts attached together) instead of the Y-axis aluminium extrusion, which is under a lot less force. It wouldn't need to look exactly the same either, as long as it has the appropriate mounts for the things that need to attach to it, and could probably be integrated with the Z axis/motor mount. I don't think it really would make sense though,by jstck - Ormerod
Quotedmould It also means doing a "dry run" by reading the entire g-code file before starting the print, which could potentially take several minutes (though such "priming" could be done under user control). The Duet CPU is pretty snappy, I would guess it could churn through a typical 2MB/100k-line file in just a few seconds (and possibly be limited by the SD card speed). It has to run through tby jstck - Ormerod
In theory it should be possible to give a very accurate estimate of the print time, if you have the gcode, any in-printer settings (such as firmware limits on speed and acceleration), and estimates of any "wait for warm-up" commands (which generally only happen once at the very start). If you go through each move and calculate how long it will take and sum that up, how far does that really differby jstck - Ormerod
The setup should only have to be done once, after that it might be some tweaking when rebuilding things or some firmware updates. The config.g file resides on the memory card (in the sys directory). Initially you will have to edit that by inserting the sd card into a computer, but if you have network connectivity (which is one of the things configured in config.g), you can upload new versions stby jstck - Ormerod
Quoteappjaws1We should pick the most accurate one and try and improve the calculation so that it can be relied on regardless of size or complexity of print. The thing is, there are situations where each method will be "the worst", so just saying one in particular the most accurate one is far from straightforward. Best option to give a single value would probably be a weighted average (where theby jstck - Ormerod
It's also a generally good idea to use loc-tite (or any generic non-permanent thread-locking fluid) to secure all screws that are threaded into metal and subject to movement. On the Ormerod that would be things such as the pulley grub screws and the M3 screws that hold the motors in place.by jstck - Ormerod
There are tons of bolts on ebay. Just search for "m3 hex bolt" or something like that. Here's one of them.by jstck - Ormerod
If you upload via web interface it's one file at a time. If you copy to the SD card or via ftp, you should be able to do lots of files at a time (how depends on your os/file manager or ftp client of course).by jstck - Ormerod
Even on some "simpler" board/firmware (such as RAMPS or Melzi with Marlin), it should be possible to run the dc42 sensor with it. If the sensor-board firmware could be changed to send out a "pure digital" on/off signal that could be used to trigger the z endstop input (where you normally connect the microswitch). Would require z homing to be done at specific XY coordinates (and possibly slower spby jstck - Ormerod
Since it still has to contain the same information (to be convertable back and forth), I don't really see how any other representation of it could be "better" than just a nicely commented section of G-code.by jstck - Ormerod
Add a "T1" to the start g-code section in Slic3r (or at the end of config.g), that should do it. Edit: You may need to have something like "M563 P1 D0 H1" in config.g as well. What firmware version are you on?by jstck - Ormerod

There are about as many ideas on how to get things to stick, as there are people with 3D printers, and most people (me included) have ideas based on very subjective personal experience. For both PLA and ABS, I've had pretty good results with glue stick on glass. For PLA though (which is what I print 90% of the time), I mostly use blue painters tape, as it is for me the most reliable method and hby jstck - Ormerod
If it adds significant cost or complexity, don't bother for my sake. But I'd be perfectly happy to have the brightness set to full or controlled via a trim-pot or something (even if I have to resolder stuff on the PCB to do so).

Would it be possible to have a few extra pin headers or pads on the pcb for "leftover" inputs/output pins on the processor, for future expansions? Just for the possibility of later adding stuff like buttons, swiches, LED:s or buzzers.

Quotedc42My inclination is to go with the ATSAM3S1A or ATSAM3S2A. But I'd welcome input from potential users. I would prefer something arduino-compatible, but as long as it can be built and uploaded with command-line tools (outside any fancy IDE's) I could live with it.by jstck - Ormerod
Quotedmould The Z nut trap is another part with significant overhangs that is difficult to print, and could almost certainly be re-designed to be easier to print with no loss of functionality. It could probably be made into a large square block and printed upside-down. The only overhangs would then be in the screw holes.by jstck - Ormerod
Printing things with those kinds of overhangs requires the right temperature and cooling, lower temperature and more cooling usually makes my prints curl up less. The skipping along the X axis is probably the print head getting stuck in the curled-up bits and the motor skipping steps. In this particular case, that curved top surface obviously serves no functional purpose, and a straight one doesby jstck - Ormerod
QuoteKimBrown ... made me wonder if it might not be easier and more versatile to go the R Pi route ... It would be easier in the respect that it would "only" require software, as it uses available standard hardware. But as already mentioned, that would be more expensive, and of course larger space-wise. However, given the work dc puts into this project software-wise, the same firmware solutionsby jstck - Ormerod
