Hey guys, First-time poster here! I'm toying with a new concept-- what would you guys think of a service that allows users to customize FDM printers based on their needs-- that way, they get their mostly-ideal machine without paying for anything they don't want to pay for. I've been looking for something of the sort but haven't managed to find anything. Any thoughts?by kman1863 - Let's design something! (I've got an idea ...)
Actually, if it's the psu you're referring to (and it appears to be that way) and not the bed, 400w is pretty normal. I agree with Dust, though-- 150c is pretty high, I've never done anything over 90 (but, as said above, it can go a bit higher). Is there any reason you need it to get that high? Because if there is, I would suggest looking into a higher temp bed altogether. Also, you said that aftby kman1863 - RAMPS Electronics
Hey guys, This is probably a better question for an electronics forum, but I thought I'd ask the people who know the RAMPS best first. On the RAMPS 1.4, a 100µF capacitor corresponds to each of the stepper drivers, but I can't figure out why they're there or how they fit into the circuit itself. Could anyone tell me anything more about these capacitors? I've said all I know about them. On the dby kman1863 - RAMPS Electronics
Thanks everybody! Great place to start.by kman1863 - Controllers
Hey guys, I've worked with RAMPS for a while now, and I've decided I want to try deigning my own board for a custom printer. I'm an electrical engineering student, and I know a fair amount about circuits and electronics. However, I've never designed something this complex, so I was wondering if anyone had any info on how to get started with designing your own print board? I'm sure there's a resoby kman1863 - Controllers
Hey guys, I'm looking to buy a ReprapDiscount smart controller for my printer, but I'm worried about maxing out the 30 amps on my psu. Could anyone tell me what the current is on one of those (or even the voltage, I'll take anything)? I can't find it for the life of me and I want to know that my setup can handle it before I buy it. Any help would be appreciated. Thanks!by kman1863 - RAMPS Electronics
Hey guys, I seem to be in a bit of a fix here. I have an Arduino Mega, RAMPS 1.4, and a 12v (30A 360w) power supply. I tried to send commands to my motors (bipolar steppers) via pronterface, but they have been extremely unreliable. Sometimes they twitch, sometimes they jump, other times they don't move at all. Recently, they simply rotate haphazardly in one direction, then another. Nothing muchby kman1863 - RAMPS Electronics
I'm getting pretty much the same issue, except I installed the jumpers and not much has changed. When I send a command, the steppers jump a little, then vibrate and make a lot of noise, but don't rotate any further. They don't rotate backwards, either, but I've been told that's just because I don't have end stops hooked up yet. When they are hooked up to the extruder pins they work fine.

No particular reason, I'm totally open to that. Would that be paired with ramps, then?by kman1863 - General
I'm looking to build a 3D Printer driven by one of the standard Arduino boards. I know Adafruit has their V2 shield that can work with steppers (I've also noticed the grbl boards and the Arduino CNC board) and I've found multiple gcode interpreters and senders for Arduino boards. I've even seen code that makes an Arduino compatible with Repetier host. Can anyone tell me which compilation of boardby kman1863 - General
