I know.... but my question is:
Is HIPS compatible with ASA?
I tried to print an object using ASA, with HIPS soluble support structure. The ASA nozzle temperature was set to 255C, and HIPS temperature was set to 240C. Bed temperature was set to 80C. In the print, I used a raft of HIPS.
However, I find the ASA does not stick to the HIPS at all! So is ASA really compatible with HIPS? If not, then what soluble support structure should I use with ASA?
I know I can rule out PVA, as PVA will not be able to withstand a bed temperature of 80-90C.
swclark: I am most interested to see how long can the object remains on the glass before it loses adhesion. Also do you wait for the hairspray to dry before heating up the plate and/or start printing?
erniehatt: Just thought of a problem. I apply the glue stick directly onto the glass just before heating it up. If I put too much glue onto the glass plate (i.e. layer of glue on glass too thick), will it cause the object to lose adhesion after prolonged printing?
prolonged printing is very important for me because I have a 40cm x 40cm heated bed, and when I print large object, it will be easily an overnight, or even multiple-day job.
erniehatt and swclark:
Thanks for your suggestions, and the glue stick is in fact PVA glue. However, what is the longest duration of your prints? I find that the glue stick (PVA?) becomes loosened after more than five hours of printing
Also for the hairspray, what was the longest duration of the print? I need to find a way for it to stick on glass for > 24 hours for some really long prints
I have a 3D printer that has a heated bed with glass surface. I set the bed temperature to approximately 60C and apply glue stick onto the glass surface before heating the plate up and print.
This works well for PLA and PETG prints if the print duration is less than 3 hours. However for overnight prints, I find that the adhesion often loosens off.
So what is the most reliable way if I have to print a PLA or PETG object on a glass surface for more than 12 hours? I need to get this right because some big prints can easily take ore than a day.
Thanks for pointing me out the tutorial, and yes I am calibrating the retraction setting right now as per the tutorial.
However, how can I address the missing letter issue in the print test? The nozzle diameter is 0.4mm, is it too big for the ctrlV test? If so, how small can I go for the nozzle?
Also, are there any other causes for missing letters in 3D prints? Currently the print speed is 50mm/s Is this too fast for PETG?
I am trying to print the test object ctrlV:
using MatterControl 1.5.3 with PETG.
However even when I set the print speed to a low value (50mm/s) and enable retraction (enabled by default anyway), the print is still very stringy with residues around the edges, and small letters either missing or in a mess.
So is PETG a suitable material for printing fine details? If so, do you have a PETG setting file that I can import?
The next version will be 1.6. Dual extrusion improvements will be a priority for that version, but the work still needs to be done. This issue is not yet fixed in git, but a bug report has been filed so you can track the progress.
So are there committs related to fixing this bug in any branches? If so, could you please point it out so we can test?
And when do we expect 1.6 to be released? Are there any chance for this fix to be available in 1.5.4?
Thanks for the feedback. These issues will be fixed in the next build. The wipe tower is significantly improved.
When you say "next build", do you mean 1.5.4?
Wipe shield and wipe tower for ALL nozzles are absolutely essential for the correct functioning of multi-extruder printer. Therefore I need it right now in order for me to print soluble supoort structures.
Is the fixed wipe shield and wipe tower already available at the git master? If not, when will it hit the git master? And which branch is this fix located now?
Oh..... after I installed an updated version of FTDI driver, it works
Could you please tell us the correct /dev file and baud rate? Is it /dev/tty.usbserial-<name> and 256000?
I am using MatterControl 1.5.3 on OS X 10.9.5, and I am using FormBot, which is similar to gCreate gMax.
I have selected the 3D printer using the wizard, and plugged the printer to the computer via USB. However when I click "connect", it says "Unable to communicate with printer" "Status: Unknown Reason"
Then I clicked "edit" to open the edit dialog. For serial port, it lists:
and the third one is chosen
Then the baud rate are shown:
and it is the 250000 that is selected.
and the "Auto Connect" option is checked.
When I switch to 115200, the printer takes forever to respond (never).
So anything wrong here? And what setting should I use?
At the moment, both Windows and Mac have the most updated package 1.5.3, which has many important improvements and bugfixes, yet Linux only has 1.5.0.
Could you please kindly provide updated packages for Linux - 1.5.3, and possibly also beta versions?
It would be great if we have an ubuntu ppa for both released versions, as well as daily builds from the git master.
Thanks! I am using the formbot printer, which does not have offset information. Of course it does not mean to have Y offset, but small inaccuracies will result in Y offset.
So are you suggesting me to use a caliper to measure displacement between the center of the nozzle holes and enter it as X offset? The issue is that the extruder is not a chimera, where both nozzles are fixed onto a piece of metal, the X cartridge of the formbot is 3D printed and holds two independent extruders with screw and friction, so it is easy to have unintended Y offset.
And how tight the tolerance is required for 2-nozzle operation for the purpose of using the second nozzle to print soluble structure?
Currently I am only using one of the two extruders on the print head. When I print, I make at least five skirt loops in order to ensure a smooth run. At the beginning of the skirt loop run, it takes some time for the plastic to come out (even if I use the manual extrusion function to extrude 10mm of plastic beforehand when the extruder is away from the bed), and then takes about 10-15cm of nozzle travel to get a stable line.
However if I have dual extrusion with one of the extruder doing support structure and raft, then how will the skirt loop of both extruders be handled? If both extruders take turn to print skirt loops, then only one of the two extruders will print immediately and the other extruder will wait for a long time. Then when the second extruder resume printing, will it become unreliable again because it has been idle? Considering my above comment where nozzle takes at least 10cm of run at the beginning to get stable plastic line.
I am using MatterControl 1.5 on Ubuntu Linux. However when I tried to switch from MatterSlicer to slic3r slicer, it says the parameters are wrong.
Google results indicates that slic3r is not working on the released MatterControl 1.5.
Currently are there plans to restore support of slic3r and cura slicers on MatterControl? If so, which branch on github should I checkout?
In most 3D printing software, there is an option to set the threshold angle for overhangs, and overhang is printed only if the threshold angle is exceeded.
Where can I find this option in Mattercontrol when I use matterslicer?
<p>I have bought a prusa i3 printer with Bowden dual
extruder, which the 3D-printed X carriage holds two independent hot
ends. Unfortunately 3D-printed part that grips the hot ends come loose
no matter how tight I tighten the screws, and often slips out during a
print. Therefore I am looking for a more reliable replacement.
am considering the cyclops 2-in-1-out hotend, which saves me from
calibrating displacement between two nozzles and things loosening.
Is it better for me to go for the 2-in-1-out hotend, or other 2-in-2-out packages such as Chimera and Kranken?
goal is to use the dual hotend to print ASA / polycarbonate object
material, and soluble PLA/HIPS/PVA support material. If the required
hot end temperature of both materials are different, (say 240C for ASA
and 190C for PVA), then does this preclude me from using cyclops?
Otherwise I will have to wait for an excessively long time for
temperature to drop / raise in each layer when switching materials, am I
I am running mattercontrol 1.4 on Ubuntu 16.04. I am using a prusa mendal i3:
which has a dual extruder, but I set the number of extruder to 1 to disable dual extrusion, and solely use extruder 1. I also turned on the raft feature.
When I print the calibration cube, each layer is arbitrarily offset in both X and Y directions by about 20mm. So are there anything wrong with the settings on mattercontrol, or is it the firmware problem?
I did not load any firmware onto the motherboard of the printer. I am just using the motherboard out of the box from the full kit
