Re: Upgrading motors
Ah I see! That's definitely something I'll look into. Thanks for that! As for the motors, I'm currently using 15s for direct drive because it is running 1.75 filament. See, I'm trying to make...

Why not back parts supported by libopencm3? It makes for a decent HAL for Cortex M3/M4/M0 parts from ST, TI, NXP, and Atmel. It's rough around the edges, especially in support for non-STM32 parts, but...

Just make sure the geared stepper has METAL gears! If it has plastic gears inside, those wear quicker and when the motor gets stopped for some reason, by a blockage in for example the extruder, the...

QuoteThe DRV8825's can do a bit more current, and they support 1/32nd steps. The A4988's only support 1/16th steps. Actually, i've thought about changing my pololus from 1/16 back to 1/8 steps. I...

Well, I don't know how it works for steps exactly, but my guess would be: 1.8º per step on your motor. 1/16th microstepping would mean 100 / 16 = 6.25% (1.8º / 100) * 6.25 = 0.1125º per microstep...

I smell evolution! :) Sad enough, not enough in my pocket to start a new project at the moment, but I really, really like this design. One question about the 'high-power mosfets', where are they...
View ArticleRe: Replicape, a BeagleBone 3D-printer cape, is ready for pre-order
Ohmarinus, good question about the mosfets. Most electronics boards that I have seen drive the mosfets directly from the microcontroller which gives a slow transition between the Off and On state of...

Thanks for your reply. This new board seems 'ideal' for most conventional Reprap's. After a long search I found out that the board uses the DRV8825 stepper drivers, it might be worth mentioning in the...

Nice, oh, just one small thing: " 5 stepper motors (DRV8825)" Shouldn't it say drivers instead of motors then?

I saw your design on G+ and commented there (Re: good choice on connectors), but just thought of something else to ask. Do you have any thermistor input protection (over-voltage)? I don't know how...
