It sounds like you're thinking of something like having one extruder do the perimeters and then having each one do half the infill...Otherwise I don't know why you wouldn't just build two printers. That's an exotic concept for which you're probably going to have to do most of the footwork yourself. With seven independent axes I'd think you'd need to repurpose a Duet and Duex4 or do a master andby IMBoring25 - General
Most RepRap delta support assumes a linear delta mechanism. I've seen some discussion of SmoothieBoard/SmoothieWare having experimental support for a rotational delta geometry like that one but I have not independently verified it.by IMBoring25 - General
What resistance does your meter show with the leads shorted to each other? You have to subtract that to get the actual resistance of the circuit. This performance doesn't sound odd for a ~1.2 ohm bed on ~12V, especially with a heat spreader and an un-insulated back surface. There's a reason 24V mods are popular.by IMBoring25 - Printing
M570 S is the command you seek to change the heater timeout. It can be added in your config.g. Another option is to do a staged heat-up, setting intermediate temperatures along the way. Some PID tuning might be useful too.by IMBoring25 - Firmware - mainstream and related support
I would suspect it's non-manifold but can't tell from my phone. Load it into Slic3r and look in the lower right corner of the window. If it says NO after Manifold:, you'll need to load it into some software package with STL repair capability first. There is a version of netfabb available that is free for personal use that has this capability.by IMBoring25 - Slic3r
I had not found that functionality. I'll have to look into it. Estimates after the print starts don't tell me if I can start and finish the print without leaving it unattended.by IMBoring25 - Slic3r
Repetier-Host and pronterface both provide estimates. That's the main thing I miss with the Duet web interface.by IMBoring25 - Slic3r
Unfortunately, I've seen very little in the way of reports of ABS and PVA adhering to each other. I've not found anything that works on my machine. PVA and PLA are compatible but then you're modeling in PLA and missing out on ABS's mechanical properties. ABS and PLA are compatible but it takes some pretty nasty chemicals to selectively dissolve the PLA. I have had some success with PETG overby IMBoring25 - Slic3r
I've had a couple of prints with similar features that I've designed with a single-nozzle-thickness wall supporting the edge of the feature. Then the feature can be built as a bridge instead of an overhang, and with a pair of diagonal cutters and a file, the wall comes off pretty easily and fairly cleanly. I've had good success with this approach. YMMV.by IMBoring25 - General
There's a separate section for the extruder parts, if those are what you're missing.by IMBoring25 - General Mendel Topics
It's probably not making a huge difference, but why are you resetting Z zero .01 above what autolevel determined? 10mm of feed stock, with 1.75mm filament and a .4mm nozzle, is going to leave a 191-mm string hanging out of the nozzle (and that g-code will actually extrude three times that). It doesn't surprise me that won't stick. If you want to do a purge like that, your machine needs to haveby IMBoring25 - Reprappers

You can use a text editor to insert pauses or to manually cut a single gcode into several files to be run in sequence. I've used that strategy to embed captive nuts inside the x carriage for my Mendel. You'll either need to devise gcode to do the unload and the load or disengage motors and re-home after the change. Another option, if the cut-over point isn't critical and your extruder loads smby IMBoring25 - General
Are you sure the motor is skipping steps or might the hobbed gear be digging itself a hole in the filament? Either way, first guess would be the resistance to extrusion is increasing, which is often because the heatsink and fan are not functioning correctly and are allowing molten plastic to creep up the hot end. You can kill the print and immediately pass the printer M84, then try pushing theby IMBoring25 - Reprappers
1) I have gotten that behavior when I was messing with it. I believe it occurred with a minimum skirt length set and ooze control may have needed to be active. 2) Make a tall cylinder and cut it to match the last height where there's an extruder change? That's the way I've done it. 3) That may be Slic3r or it may be your firmware. What are the custom g-codes you have configured in Slic3r thaby IMBoring25 - Slic3r
Is Slic3r forgetting the changes even if you save them, or can you close and reopen Slic3r and have the setting retained? I believe the fix for an overwritten setting was wiping out the temp files. Is it the RepRapPro version of Marlin or the standard version? The standard version uses G10 for a firmware retraction but the RepRapPro version uses it for tool offsets, including active and standbby IMBoring25 - Slic3r
What electronics and what firmware? By default, Slic3r passes selection of Extruder 1 as T0, Extruder 2 as T1, and so forth. If your firmware is expecting something different, that's your problem. Some older versions of RepRapFirmware reserved T0 to disable all tools and started the extruders with T1. If that's your problem you can either change to a newer or different firmware or write a posby IMBoring25 - Slic3r
In the lower-right corner, does it say your model is manifold?by IMBoring25 - Slic3r
Repetier-Host has start and end g-code that it will prepend and append if configured to do so. When I use the load to SD card option, it has checkboxes for whether I want to include the start and end G-code. I uncheck them. It sounds like your workflow is resulting in RH adding that extra g-code. There should be a setting somewhere to prevent that but I'm not familiar with it.by IMBoring25 - Reprappers
This is very sad all the way around. I have been very impressed with the engineering of their products and the level of service and support provided. I inquired about the temperature limitations of the QuickSet hot end shortly after it was introduced and was told the primary limitation is the thermistor being used, which is good to 300C. With alternate temperature-measurement provisions, theyby IMBoring25 - Ormerod
Now you have two PTFE tubes. Either cut the bottom fitting off the old one and use it in the push connector, or cut the top fitting off the new one, unscrew the top fitting off the old one, and adapt the top end configuration of the new one to match what you need for your extruder. The justification I've seen most frequently for the heater change is for safety, as the 40W cartridge is capable oby IMBoring25 - Ormerod
I sourced a Duet from Think3DPrint3D after smoking the heated bed terminal on the Melzi for the second time. Their current production comes with headers for 2.54mm Dupont connectors. If you're sourcing one elsewhere, I'm not sure what they'll use, so I'll assume you're going through T3P3. Unless you can find pre-made looms, you'll need to get 2.54mm Dupont crimps and housings and make your ownby IMBoring25 - General Mendel Topics
It's strange that your firmware wouldn't already be set up to be compatible with normal coordinate system conventions. You can build a post-processing script that would change the Z coordinates as Slic3r generates them to generate the Z coordinates you need to make the machine behave as you'd like. It would really be more correct to change the machine so it works in a traditional way. Unless yby IMBoring25 - Slic3r
Quotejbernardis There are 3 different axes to rotate around and infinite number of degrees around each one. How in the world could slic3r know how to "automatically" rotate?? Well, either it could be configured in an ini script with the axis to use the way netfabb does it in their GUI or, as the Slic3r command line version does, it could assume rotation about Z.by IMBoring25 - Slic3r
The command line version has a --rotate switch that rotates the model about the Z axis by the number of degrees you specify. You will have to pass it the switches for your INI files as well, along with any other changes you want to make.by IMBoring25 - Slic3r
It looks like G54 and G55 are used on CNC machines for changing coordinate systems. Interesting that it would show up on a 3D printer. There are several options. You can code a post-processor to insert those commands after T0 and T1 commands. You can set the Printer Settings, Extruder *, Extruder Offset settings. This won't actually change the coordinate system, but it will make Slic3r passby IMBoring25 - Slic3r
You actually don't have to trick it quite that much. If you hover over the Start G-code block it says that if it sees M104 or M190 commands in the start g-code it will not prepend those commands so you can alter the order of things. I use: M140S ; set bed temperature M190 ; wait for bed to reach temperature in mine, and that can be placed anywhere in the start G-code sequence you want it.by IMBoring25 - Slic3r
I second that. Either you're not saving the changes or there's something wrong with your installation, possibly a permissions issue with the folder where the slic3r.ini file is stored.by IMBoring25 - Slic3r
A few other things... Unless you want to not just level the bed but also set Z=0 using manual adjustment screws, you need a far finer adjustment than your layer height to optimally set the height for your first layer. Fine resolution in Z would be needed if you are using autolevel or printing spiral vases. What are you hoping to gain with coarser resolution? Since Z only moves a layer heightby IMBoring25 - General
I'm not a Slic3r dev. They marked that function as deprecated in 1.2.5 for the reasons they discuss at including, apparently, that it was put in to deal with the old gap-filling algorithm that instead of manipulating extrusion widths made fine zigzags, which would tend to set up harmonic oscillations for an extended period of time on machines that wouldn't otherwise have a problem with it.
