Does it Shutdown or enter in low energy consumption/sleep mode? I think I would probably use a ATX power supply with power switch to isolate everything from the power source. Not only to spend less energy(Energy in Brasil is NOT cheap), but to protect it from electrical outages.by MtCS - Next Wave Electronics Working Group
Hi! Why Gen7 does not have a power switch? Do you Think its a good idea?by MtCS - Next Wave Electronics Working Group
Its not compatible, thats why i suggested the TaskForce. The Maple layout is compatible with arduino UNO, but it has some additional headers that complete 39 IO pins, thats why it can be done with the Maple layout. If LeafLabs cooperate with us, MAPLEs next big brother, (MAPLE RET6) that carries the 512MB Flash, will also be compatible in the future...by MtCS - Next Wave Electronics Working Group
LeafLabs released Maple RET6 that comes with a STM32F103RET6. "The RET6 has over 3 times the RAM (64K, 4 times the Flash memory (512K, and many additional peripherals (like DACs!) not present on the RBT6. " And it is only U$10 more expensiveby MtCS - Next Wave Electronics Working Group
Correction. LeafLabs released Maple RET6 that comes with a STM32F103RET6. "The RET6 has over 3 times the RAM (64K, 4 times the Flash memory (512K, and many additional peripherals (like DACs!) not present on the RBT6. " RET6 is more similar to LPC17xx.by MtCS - Next Wave Electronics Working Group
First of all, I just want to do what I did not do before. Congratualations on the design and production, that initiative is very good for the community in general. The All-in-one aproach is very good, I always liked it. Unfortunely I cant afford it right now. If I could I would buy your bord for sure. Though the advantage of a RAMPS like paroach is that you can afterwards upgrade just the shieldby MtCS - Next Wave Electronics Working Group
I surely disagree with some of the claims that Arduino performance compares to the Maple Leaf. The Maple is not much better only because of the Clock, the DMA can make a huge difference to IO like SD cards, the 32 bits can make float point instructions much faster than in a 8bit FPU. If the Maple don't heve enough flash/SDRAM memory for you, thay will launch a Maple Native some time soon. 512Kby MtCS - Next Wave Electronics Working Group
Hi, Dont get me wrong, but you could used the Leaf Maple board and made an shield containing all stepper controllers + extruder control like a RAPMS, it would something like a ReMPS, heheehe. It is Arduino API compatible, so to port the firmwares to Maple would be much easier, you wouldn't have to maintain as much sourceCode/hardware as you do now...by MtCS - Next Wave Electronics Working Group
Hi! It would be ok for me to use a DC-DC step-up converter to increase the pololus input voltage to increase servo speed/torque? Would the higher voltage it even be used? I heve one of those: Its weak but I can get a better one.by MtCS - Stepper Motors, Servo Motors, DC Motors
I think Trajectory smoothing would be essential for greater printing speeds. The stride(the derivate of the acceleration) should be avoided... You probably know that better than me, my field is Computer Science not Mechanic Engineer. Just keeping this important post alive!by MtCS - Firmware - experimental, borrowed, and future
Actually I was just brainstorming a little bit. Using Papilo idea is interesting too since it provides additional SRAM. SRAM would be very important to run more complex algorithms. Of course it would not be trivial, it would be very challenging to use FPGA or CPLDs to implement complex functions but, with some creativity I think it could achieve great results. Any ideas?by MtCS - Firmware - experimental, borrowed, and future
Hi! I am not expert in electronics hardware neither firmware developer, but I think this Amani 64 CPLD Shield can overcome the performance limitation of Arduino to run special math or something like it. Maybe implementing in CPLD something like a graphic display with 3D print visualization could be possible... Or maybe just do some suuuper fast math with it...

Por algum acaso alguém sabe de algum fornecedor de plástico em filamento aqui no Brasil? Importar plástico fica caro no frete... na Esunpla: O filemanto: 3mm,$15/kg, (barato) 1.75mm, $17/kg, (bem barato) Frete: delivery fee $60 for 2.5kg, (50% mais caro que o frete no site ) delivery fee $100 for 5kg.by MtCS - Brazil, São Paulo RUG
though you would have to port the code to the cellphone OS... It also would be very nice... but its not the easiest thing.by MtCS - Firmware - experimental, borrowed, and future
To entrando no negócio tb! Comprei as peças de plástico no ebay e o resto em lojas locais. Pretendo comprar o kit das placas eletrônicas + motores + printbed + correias no site O arduino vai ser no ebay tb, tá a metade do preço. E o hotend vai ser na mendel-parts: e a primeira otimização que pretendo fazer é colocar rolamentos lineares: BH - MGby MtCS - Brazil, São Paulo RUG
Você tem idéia de quantos kits vai querer?by MtCS - Brazil, São Paulo RUG
Another option would be a linux installed in a beagleboard... that board is veery powerful and can run a OS (Windows(?) or linux). in this case you would need the beaglebord + the LCD and the Raprap and would not need to program anything... no PC needed!by MtCS - Firmware - experimental, borrowed, and future
for $ 84 you can get a I2C colored ICD with touchscreen... that would be awesome to control the reprap! but for status display i would use: for $15: or this one: for $20?: or this: for $48: Unless you use a simple serial display like the last tree ones you would need to program a lot... but the results would be better. The serial displays are very simple to program, itsby MtCS - Firmware - experimental, borrowed, and future
