There are a lot of people who would say a direct data connection to ANY computer is not suited for 3D printing. SD card does circumvent a lot of potential issues.by IMBoring25 - General

Most hot ends not made by E3D like more than 2 mm of retraction.by IMBoring25 - Slic3r
I would agree M190 would be a more appropriate bed temperature reset than M140 in extreme situations, but most people who use that function start out hotter for bed adhesion and then cool the bed for subsequent layers and don't change it nearly as radically as you're wanting to do. For most firmwares, in that usage, it wouldn't wait anyway and they wouldn't typically want to wait for it if it diby IMBoring25 - Slic3r
It shouldn't be necessary to go to room temperature for first-layer adhesion. 80C is far too hot for PLA, significantly above glass transition temperature. You're trying to use the heated bed to do the job of an enclosure. Normal PLA bed temperatures are in the 45-55C range. An enclosure makes a world of difference for larger parts and you wouldn't need to mess with temperature cycling. Slicby IMBoring25 - Slic3r

Does this still have the tweaks for the ADC crosstalk that were in the earlier alphas? I got the first Duex4 extruder wired up and it was requiring some very aggressive ADC compensation that was also affecting all the other temperatures.by IMBoring25 - Ormerod

While they're no longer operating, they kept their page up, so all the documentation is still there. The Melzi-based Tricolor is further down the Documentation page, under Discontinued Machines.

When posting questions, please include at least machine type and firmware. This behavior can occur when you have a normally-closed endstop that is not properly connected, so the machine thinks the endstop is always triggered. Some machines are configured to move to the endstop quickly, back off a little, and then hit the endstop again more slowly to get a more precise position. When this symptby IMBoring25 - Printing
What leads you to believe you can't configure 16 tools? I just tried turning number of extruders up to 128 and it didn't seem to be having any difficulty.by IMBoring25 - Slic3r
I'm not familiar with simplify3d, but most host software has provision to associate custom buttons with a sequence of gcode. There are boards with provision for endstops for the extruder drive axes but I'm not sure how much custom work you'd be committing to to make them work in that way and you'd have to design the mount for the endstop on your extruder drive.by IMBoring25 - Reprappers

If it's not centering correctly on small parts it won't center correctly on large parts. You'll just crash the machine. Save the trouble.by IMBoring25 - Printing
G0 is treated the same as G1 in the reprap implementation. G2 and G3 are supported in some firmwares but not any slicers of which I'm aware. It would take some interpolation since the input files are STLs, which inherently segment curves. G10 varies. It only does something like what you're expecting if you're running RepRapFirmware, MachineKit, or the RepRapPro branch of Marlin. Otherwise itby IMBoring25 - Slic3r
This one is easy. You just need to figure out how far the drive needs to turn to get filament from the extruder drive and write start gcode that extrudes that much filament, waits for heat-up, then extrudes a little more and either waits for you to pull the extrudate off and launch the continuation of the print or goes to a purge canister that you'd have to design. Then you'd need end gcode toby IMBoring25 - Reprappers
You need far more than 5 seconds to be able to lay another layer on ABS (probably more like 20-30 seconds depending on other settings). I have printed that generally successfully with very aggressive automatic-cooling settings and a very low minimum speed, but it would be easier just to print two of them, separated by far enough for travel time to be significant, to kill time. You can also makeby IMBoring25 - Printing
I'd suggest slowing your retraction to between 10-20 mm/s and knocking 10-20 degrees off your hot end temperature. With PLA in particular the v6 does not like long or fast retractions, and it's worse with temperatures at the high end of the range. If that doesn't fix it, they've changed their instructions since I got mine to add thermal compound during assembly to mitigate the heat creep. Sincby IMBoring25 - Printing
The firmware and the slicer have to be configured the same way. It's probably conceptually easiest to set your endstops as zero and set nozzle offsets in the firmware to make the forward-left corner of the bed (0,0), but you can also figure out how far away from the bed the endstops are and set them to accommodate the offset. With either of those approaches Slic3r just needs to be set to a 250by IMBoring25 - Printing
You don't have the whole picture of the workflow, which is understandable if all your exposure has been to the pre-packaged all-in-one solutions. Gcode is the sequence of instructions for the printer to execute to do a print (or anything else, for that matter). Move the nozzle to this point, then move it to this other point while extruding this much filament, then retract this far, lift the nozby IMBoring25 - General
I'm not specifically familiar with the Pegasus, but it's a Mendel derivative and the Mendel traditionally uses an origin at (0,0) (bed center at (100,100) or thereabouts). Slic3r used to use bed center, but when they now say origin, they mean the coordinates of the bed corner at minimum x and minimum y. Set that to (0,0) and the bed to 200 x 200 and Slic3r will center your parts at the point whby IMBoring25 - Slic3r
That fits. I'm not familiar with the older ones, but the E3D v6 definitely doesn't like that much retract, especially with PLA (and 220 is pretty hot for PLA, too, which would exacerbate the issue). At the bottom of the gcode file Slic3r adds a long string of comments defining the values of all the configuration variables that were used in the slicing. Could you post that section?by IMBoring25 - Slic3r
If you're trying to turn this process basically into taking a Polaroid I can see the simplicity argument, but you're talking about handing off the slicing and g-code generation either to the printer or to a heavily-integrated host software with slicing capability. Personally, the printer should print and the host software should host. I like that I can fully prepare the gcode for the next job wby IMBoring25 - General
Those are not the same settings. The Slic3r code is a roughly 5mm retract at 30mm/s. That could be a big problem if your hot end doesn't like long or fast retracts (v6?). You also have Slic3r configured to use absolute distances for extrusion, so each distance it commands is relative to the extruder position the last time it commanded a G92 E0 reset to zero, not relative to zero for that partiby IMBoring25 - Slic3r
Some firmwares will restrict motion if the machine hasn't homed to prevent crashes. You will either need endstops to print or you'll need a repeatable way to put the nozzle in roughly the same place in X and Y and exactly the same place in Z.by IMBoring25 - Printing
RepRapPro offered "hardware kits" of everything but the printed parts. They're not offering anything now and I don't know if anyone is still offering anything similar. You can self-source the BOM but that is likely to be more expensive than even a complete kit due to shipping and minimum order quantities.by IMBoring25 - General
That's one theory, but the explanation he gave for using the designers' photos was that he hasn't made all the items yet and that he would replace the photos after the first order.

The Rostock Max uses melamine as its primary structural material. The bulk of the wood is blocked from moisture intrusion by the laminate coatings and many builders choose to paint the edges for cosmetic purposes as well as to attempt to block that remaining point of entry.

Is your home behavior configured to home quickly, back off the endstop, and home again more slowly? If, as is typical, you are using normally-closed endstops, I would expect one of the connections between your board and your Z endstop is becoming intermittent and, when you have no continuity, the board sees that endstop as always being triggered, so it stops immediately, backs off, and stops immby IMBoring25 - Printing
One of the neat things about these systems is that they're completely configurable. You can use whatever settings you want for whatever reason you want. I've been known to modify my standard profiles with a lower bed temperature if a given printer has a heated bed that struggles and the printed part is small enough not to need the usual temperature.
