The quick releases sold by Prometheus have been working fine for me. The failure of your connector could be blamed on poor quality, but it could also be caused by too much back pressure from the hot end.by etfrench - Reprappers
This is what I'm using now: You'll probably need a lathe to fabricate it.by etfrench - General

I've used pieces of PTFE cut to the correct height as supports for flat areas. From Paul's post, it looks like this could replace most of the internal support in the helmet print. ABS doesn't stick to PTFE, so it might be better to use a material that ABS will stick to but still release.by etfrench - General
Here's a section view of my effector: The upper magnet is more than enough to hold the arms in place. The lower disk magnet just provides a nice socket for the ball plus a little insurance magnetism.by etfrench - Delta Machines
Adding a string and spring tensioner for each leg would be a simple solution. It looks like there is enough room on the effector and carriages to add these.by etfrench - Delta Machines
You can use the 'Load Modifier' feature in Slic3r to change extrusion settings in the problem areas. It's located in the object's settings dialog. p.s. I hate workarounds, but sometimes there is no choice.by etfrench - General
Filament was dryer at the center of the spool? Or temperature that far from the bed is lower??by etfrench - Reprappers
You need to calibrate the printer before setting layer heights in the slicer. Did you change the mm/rev setting in the firmware when you changed lead screws? Can you share the link to the banggood screw?by etfrench - General
Thanks for the replies. There won't be a lot of force on the hinge, so the vapor smoothing shouldn't affect the operation. Painting would require a lot more skill to make the parts look good. There are way too many nooks and crannies in the design for my skill level at paintingby etfrench - General
I have a hinge printed in ABS and want to smooth the surface for looks. The hinge uses a steel rod for the pin. The holes have been drilled and reamed for a tight fit on the steel rod. Would it be better to leave a rod in each side of the hinge (using different rods for each side) during the vapor smoothing or just do the vapor smoothing without the rods?by etfrench - General
PTFE machines nicely, so you shouldn't have any trouble machining a bushing. It will cold flow over time, so constraining it in a metal tube would be best. In a 3d printer, there may not be enough force on the PTFE to cause it to flow very much. In another non-3d printer project I used cast polyurethane resin to constrain the PTFE tubing. It's been working well for several years. McMaster-Carby etfrench - Delta Machines
What's with everyone using the term 'leadscrew' as though it described a particular thread form? Acme threads in imperial and trapezoidal threads in metric are the most common forms, however triangular and square threads can also be used. Acme and metric trapezoidal are similar but have slightly different thread angles, 29* vs 30*. Triangular threads (aka threaded rod) can be just as accuraby etfrench - General

So far, I haven't seen a single model on Thingiverse or Youmagine that didn't need to be edited for my needs. If they were provided as gcode only, then they would be virtually useless. Why do you spend so much time slicing? For me, a model that takes an hour to print takes less than a minute to slice. Now, if someone would make a slicer that could consume more sophisticated 3d models like IGEby etfrench - General
I suspect this would be a less expensive and more efficient method.by etfrench - General
Technique is important as well when striving for accuracy. Hint: Using the thumbwheel is not the best way. p.s. Most micrometer sets come with accurate test blocks.by etfrench - General
I think four rails on the Z axis is over-constrained and that isn't a good thing.by etfrench - General
QuotePhytone After going through PLA, ABS and PETG with great results - I'm trying Nylon (3DPrima Nylon) Have cooked the Nylon for 10 hours in the oven to make sure it is dry, but every time the print gets more than 0.8mm thick, the darn thing lifts off the bed. Have cleaned with Acetone - nope Have put down a coat of hairspray - nope Have put down a coat of PVA/water - nope Have played arounby etfrench - General
345mm length for 300mm print area sounds about right. You can make the bed as large as you like as long as it doesn't hit the belts. Enclosing the printer is harder when the build plate extends past the horizontals. I'd turn your printer upside down as it makes wiring and maintenance a lot simpler. A non-fake Fotec SSR makes using mains electricity safe. I'm using a Keenova 300mm 120v 500wby etfrench - Delta Machines
Look at the Load Modifiers in Object settings dialog.by etfrench - General
If you add another step in your process using PLA, the cleaning will be even more effective. See nophead's method here:by etfrench - General
Full length tnuts are fairly easy to make if you have a drill press, a mill, or lots of patience for hand layout. I used .125"x.5" aluminum bar. I think the full length tnut may be more precise as the holes don't deviate from the centerline. They are much cheaper as well.by etfrench - General
It's odd none of the marlin experts have responded. I use smoothieware, so can't help with the settings.by etfrench - General
Try setting the manual move rate to the same rate as homing uses. If there is no vibration, then increase or decrease the manual rate until it does.by etfrench - General
Perhaps their standards are so low, that any filament would pass their inspection. The least they should have done was to return the OPs spool without charging shipping. I for one won't buy anything from them based on this thread.by etfrench - General
GT2-2mm belt height is slightly smaller than 1.5mm, tooth height is about .7mm (dimensions are available online). I used a 2mm slot in my carriages for the belt to pass through.by etfrench - Delta Machines
I'd use aluminum, but I have a lathe that I can use to bore the sleeves accurately. You could use one of the tubes as a mold for a carbon fiber layup. Internal sleeve/plug would also work as well as an external sleeve.by etfrench - Delta Machines
