Re: linear rail mounting questions - 8 years ago

Please don't let the rod rotate! It's much, much more precise to anchor your rod as strongly as possible, and just use another rod as a driveshaft.

dc42: Why not just test them and find the temperature at which they don't get too hot?

Re: Strange Heatbed temp fluctuation - 8 years ago

Try a different firmware, e.g. Repetier. If it doesn't work, get a new thermistor (and switch back to Marlin if you want). If it does, it's in software.

Re: Spltting Thermistor Signal? - 8 years ago

I think it would depend on how the pins are read. I wouldn't do it if I were you.

Also: If you really need reliability, try booting Linux off a flash drive. You don't even need to install it, and you'll avoid all the nastiness that comes with Windows.

Re: Z axis - screw opposite linear support? - 8 years ago

If you're gonna use two screws and two rails, I suspect this is the ideal arrangement: R------S |---------| |---------| S------R This allows for the maximum distance between elements, giving better leverage. Also, the bed's weight is evenly distributed. Any disadvantages you can see?

Re: New Z-Probe uses Load Cell - 8 years ago

MKSA: The advantage of load cells, FSRs, etc. is that they trigger with basically zero movement. This allows precise, rigid positioning, while still detecting force.

Re: headbed with glass plate lag ? - 8 years ago

I think that's real, i.e. the top of your bed is actually a different temperature from what the sensor is picking up. So, just wait, if you want the temperature to be equal.

I second Delta, and I'd also bring up Hbot / CoreXY machines.

MechaBits: Yes, it fits on top like a shield, like ordinary RAMPS.

Re: Why no affordable 32bit electronics - 8 years ago

The "MKS SBASE" is a Smoothie x5 clone you can get for $59 shipped one eBay. Also, the "AZSMZ" is basically a cross between an Azteeg X5 and a RAMPS, with removable stepper drivers and Smoothie-like electronics. It's $61 shipped on eBay, plus the cost of the drivers. The_digital_dentist: Clone electronics usually work. For people who don't spend as much time using their printers as you do,

Re: RepRapish Design Poll - 8 years ago

Positives/Negatives to a H-Bot / CoreXY drive mechanism? Low moving mass allows higher speed / acceleration while maintaining precision. Long, complicated belt paths add complexity. Build size recommendations, the plan is larger than 8x8x8" My ~6.5" square bed is usually enough. I would like larger, though. If you're designing your own, 12"x12"x16" seems reasonable. # of extruders and wade or

Re: 12 x 12 x 12 square frame? - 8 years ago

Build your own! Make a frame out of aluminum extrusion, like scrap 80/20 or something, and stick on a few rails and a leadscrew.

Not much info... Is it PEI-based?

Re: Are there kits that just sell the parts that aren't printed? - 8 years ago

SmartRap does that.

Re: Best filament for printer parts - 8 years ago

It depends on the part. If it's gonna take heat or high force, that rules out PLA. If it's big and can't be allowed to warp, that rules out ABS. If you can run PC, do it, but I've heard it's a pain.

Re: ridges - 8 years ago

Examine the vertical leadscrew. It could be introducing wobble. Is it a real leadscrew or a threaded rod?

Re: Delta Printer aprubtly starts moving "weird" (Duet 0.6) - 8 years ago

Check all the wires, and examine the control board for shorts or other damage.

Re: Lead Screws? - 8 years ago

Leadscrews are awesome, especially compared to threaded rod. Threaded rod is imprecise, not very straight, and literally designed to bind under force. These are not design flaws, they are design: threaded rod is supposed to be used to fix things together, not as a linear actuator. Leadscrews are the opposite. Like a good toaster, they simply take themselves out of the equation, because they

Re: heat isolation glue that works with plastic? - 8 years ago

Silicone caulk is kinda rubbery, not very strong, but also is a decent insulator and can take tons of heat. Epoxy is ridiculously strong, including to plastic, but might not be the best insulator. Gorilla glue is foamy -> nice insulator, but I dunno if it can take the heat. It does bond to plastic.

Re: Your Kit Suggestions - 8 years ago

Have you considered a custom machine? It's not for everyone, and it relies on having access to another printer, but you can make a really nice machine for $800.

Re: POROLAY Materials uses and ideas - 8 years ago

I suspect the elasticity could be taken advantage of. RC car shock absorbers? Soundproofing feet or stepper mounts for a printer? Elastic anti-backlash nut? Also, quite a few models use live hinges, which might work better with elastic filament. The Delta-Pi's carriages come to mind.
