I'd wager the layer consistency is due to not using Z screws. 2013 prediction: Z screws will start disappearing from new reprap designs.by billyzelsnack - General

Sort of NOT AT ALL like Ford writing a manual. A guy on the internet invested a shit ton of HIS time, HIS expertise, and HIS dollars into making a machine and then put the files up for everyone and you're complaining about YOUR suffering because he didn't give you enough?

I don't understand how you can work that out by just talking about the pulleys. Don't you also need to talk about the stepper resolution and the sub-stepping to arrive at a value?by billyzelsnack - General
Decent leadscrews are expensive and using Z belts keeps the cost down. Leadscrew coupling is also not as trivial as it might seem.by billyzelsnack - General
The newer design flips around belt so I can use bearings instead pulleys on the carriage. It also makes it easier to tie the ends down. This video shows it off probably better than others.by billyzelsnack - General

My hotends (Printxel) cost about $1.50 in raw materials minus the resistors and thermistor. I don't use PEEK, but I do use drilled PTFE rod for the insert. 20 hours was my initial guesstimate, but it put the printer at a $100 loss which would put them in hole $200K for 2000 printers at this point which seemed unlikely.by billyzelsnack - General

The steps per mm on the Printxel non-double pulley Z axis are 70 with 16 microsteps. So 4.375 steps per mm jives pretty well with the 0.254mm mentioned above. So on paper it might sound borderline, but in practice I have printed down to 50 microns with good layer alignment. If anything some of the other low cost components and design decisions on the Printxel are the weak link when it comes to ulby billyzelsnack - Stepper Motors, Servo Motors, DC Motors

Half of it they're trying to setup willful infringement for triple damages. I guess 3DS needs more money to buy more companies. Why innovate when you can buy or sue others instead? I do find it interesting how the complaint is trying to position that it is just unfathomable that a company might not know about the specifics of all competitor patents. 3DS probably has a lawyer army for such thinby billyzelsnack - General

I regularly experiment with a hair dryer that has a hot and cool setting. Because I am holding it it is pretty easy to modulate where and how much air is hitting the part. I can also compensate for nozzle temps diving by just moving it away for a few seconds when I see the temps going down. Even with quite a bit of control fans still suck as a magic bullet. The thing that seems to work the bestby billyzelsnack - General
I could maybe see that the actual micro stepping offsets from a given full step are not the same as offsets on other full steps. Depending on which full step you land in your offset might be slightly different. However, I don't see how that's going to be worse than the 5% error rating (0.09 degrees) of the full steps.by billyzelsnack - General
I've lately been using sanded polycarb with 50% diluted PVA spread by my finger. The PVA sticks to the sanded polycarb and the PLA sticks to the PVA. No need to apply every time either.by billyzelsnack - General
I think what we want to show are the worst numbers sampled in many spots, but that is open to interpretation due to deformation. Maybe I should try throwing it on a flatbed scanner.by billyzelsnack - Competitions
So I printed this and got within 0.05mm for all dimensions if I want to talk best delusional case and 0.1mm worst realistic case. I think that we're within the error range of measuring with digital calipers due to how easy it is to cherry pick as well as deform plastic such minuscule amounts.by billyzelsnack - Competitions
