if you use the buck convert do you lose the PWM? this is why I use 24v fans.by longbeardpolymer - General
last time I ordered dual gears from china it was $3.50 with the bearings and one axle. got a second axle with some more bearings for cheap. I really want see improved designs that can reduce the weight reduce the size.by longbeardpolymer - Mechanics
I found this I am wondering if I want to get the cheapest or most expensive smooth rods 8mm. I think the teflon film applied to the smooth rods would give me an added benefit vs simply using the smooth rods with drylin bearings. the product rep for the bearings says that these are not dry systems like graphite. drylin actually is a film that migrates out. it is dry compared to oils but still noby longbeardpolymer - Mechanics
you could try klipper firmware with a pi if you don't want to troubleshoot marlin. there is also smoothieware. there must be something in the marlin firmware that needs to be configured but I guess you will need to read the docs a little more. could take a while unless someone with more experience comes to the rescue.by longbeardpolymer - Reprappers
woops I didn't even answer the question. for some reason I rambled on about hotends. its been a long day. if you look at the BMG-M or the hermera, or to a lesser extent the titan. they are so highly integrated at this point, that I think maybe the better question is what combo is popular. the BMG clone + V6 clone are probably the most popular.by longbeardpolymer - General
v6, mosquito, dragon is a V6 up top, the micro swiss is still popular. the mosquito I think is less popular because it is super expensive and also newer. the V6 mount is probably the industry standard mount at the top so if you want standard just do that. the mosquito is pretty new on the market compared to the older and cheaper V6. bondtech is making extruders that mount to the mosquito directlby longbeardpolymer - General

you didn't say what material, what thickness and what die size, die shape, die angle etc.. you need to decide early in the project so that all your mechanical loads are right there for reference. you may want to test a punch with a load measuring device to get that data before you start.by longbeardpolymer - Reprappers
also, the nimble was changed from 30:1 to 20:1 on new models. the G5 was changed from 30:1 to 40:1. the nimble has %100 more flex compared to the G5. this is considering that the flex is a function of flex cable length divided by gear ratio. this is what actually happens at the nozzle. whatever is left can be tuned out by adjusting linear advance. there are videos on that. you also need to changeby longbeardpolymer - Reprappers

maybe the big advantage to 3d printing is that you can't go out to the store to buy supplies so you can print the things you need if it is printable. you can fix your car at home. fix your chair when it breaks. without chairs there can be no computers. think about it.by longbeardpolymer - General
I think I may have some useful information. if that main board was setup to work with a pi then that 40 pin connector would go to the pi. then that would be for octoprint and klipper. so maybe it is running klipper? and if so you can find the UART by looking at the pi 40 pin header. you can get the serial speed, stop bit, parity, flow control from reading the klipper source or at least one of theby longbeardpolymer - General
what is your level of skill with this stuff? I'm not sure if you need all the details or if you already have what you need. this is how you get a UART if all you have is the UART pins.by longbeardpolymer - General
how did you determine that it does not run marlin? it is a 32bit board. there is a short list of firmwares that will run on it. you can change the default marlin startup screen on the LCD. you can change the icons. but you can tell sometimes because the menu is like marlin. that expansion header looks like from a duet 2 but the STM32F103 makes me think SKR. did you already try the tutorial on howby longbeardpolymer - General
use the $200 kit to print parts for the $1000 dream build. the $200 kit is just barely good enough to print PLA/PHA. not as good as PETG but much better than PLA. throw a garbage bag over the whole thing if you have a cold basement. the hermera is an amazing value for the money. the SKR mini for the ender 3 is a cheap drop in replacement on an ender 3. now that you have a 32bit hotend extruder anby longbeardpolymer - General
%99 sure that is an SKR or a low cost clone of an SKR running marlin either way. they can delete features that are not needed on your 3d printer to lower the cost of the board. you will need to use JTAG if there is no working marlin bootloader over USB. there may be a jumper to enable the bootloader. compare to the SKR to see what is different and what is the same. also, before you waste too muchby longbeardpolymer - General
