Thanks! I stand corrected, I misread the ATMEL website. Based on reading other user experiences they do still have a lot of headroom to allow for overclocking up to 24Mhz, I don't mind risking damage to some cheap hardware. Just because I have a bad habit of 'what if?' and of course, it was cheap.

Resurrection time! DjDemonD, Did you ever successfully complete this mod? I've got a spare mega board and was already planning on swapping out the crystal. Just need them to show up in the mail. I've opted for a 22.1184Mhz crystal though.by obelisk79 - Controllers
I've found it interesting to follow the development. Like I said, once the design is relatively stable I'll be interesting in trying one out. My latest project has me swapping crystals on my MEGA2560 to get a little um oomph compared to the arduino reference design since the chips run 20% slower than what they are rated at.by obelisk79 - RAMPS Electronics
I had a CubeX it took a lot of work to get printing well, and recently sold it in favor of building something from scratch. It was a phenominal learning experience though.by obelisk79 - Reprappers

dc42, I don't know of any decent $37 32bit boards. do you? I'd love to see one.by obelisk79 - Controllers
Oh lord, that laptop board looks like a nightmare lol. I've done similar BGA's with a hand iron as well. Drag the pins and pray..by obelisk79 - RAMPS Electronics
Looks like fun times ahead, simple as I am, I rather enjoy a good soldering project. Ever do much SMT by hand? That's where it really gets interesting.by obelisk79 - RAMPS Electronics
Thanks for sharing. I'm designing my own printer. Much less organized at this point, but I hope to come up with something I can give back to the reprap community myself at some point.by obelisk79 - Look what I made!
derew, Any 3d Printer is fairly 'hackable'. If it uses an open source design, and no custom designed parts you shouldn't have an issue. Cartesian designs are probably the easiest for a pure beginner. CoreXY offers an alternative means of motion and is a little bit more complicated to understand. Delta printers can be the most fickle to tinker with. My personal recommendation?

Any updates on your initial prototypes?by obelisk79 - RAMPS Electronics
TMC2100 boards may work as well.by obelisk79 - General
bwahaha!by obelisk79 - RAMPS Electronics
Be cautious using 8825. They work well but require the use of diodes for smooth and quiet operation. Premade boards here:by obelisk79 - General
I have TMC2208's I think SPI would be a nice feature. But standard jumpers would still be functional. Performance information regarding the 2208 is a bit sparse but what I've seen so far looks rather positive. Ikcl, your jumper configuration sounds slightly confusing.by obelisk79 - RAMPS Electronics
Enjoying watching your progress! Unfortunately as a technician for military electronic systems, PCB design is well outside of my comfort zone but clean and effective design is something I can certainly appreciate.by obelisk79 - RAMPS Electronics

You're an animal... once you've stabilized the design some, and you meet your cost goals, let me know how to buy one I like low cost experimental ideas.by obelisk79 - RAMPS Electronics
Quality Nema17's are exactly what I'd be interested in. Preferrably high torque and low coil impedance.. The printer I'm currently working on isn't using linear bearings so I'm not sure that would be up my alley but if you did put together and order for the reprap community I'd probably thrown down for some for possible future projects. Regarding the previous discussion regarding controllers, Iby obelisk79 - Reprappers
Anyone else looking at these guys? The low weight and high temp performance have piqued my interest for a new CoreXY build I'm planning. I think they plan on releasing at the end of July.by obelisk79 - General
8825s work great for me on my ramps. I did place the simple diode circuit in the path though.by obelisk79 - General

QuoteDaGameFace I think I need to mess with Jerk and acceleration settings. What do you guys use? Acceleration: 1200 Jerk X/Y: 8 What speed are you trying to print? PLA or ABS? Temp? Do you have an active fan duct to cool while you print? Can you post another pic with something to reference for size like a quarter?by obelisk79 - General
I'm going to be the one defending ramps 1.4. It's the cheapest solution, and while the CubeX has solid mechanics it isn't going to be printing at any speed/capacity that board and it's compatible firmwares couldn't support. Others will argue with me regarding quality of cheap chinese boards, I bought mine from a reputable amazon seller and have not had any issues. My print quality went up 300% wiby obelisk79 - General

Latest print, relatively easy object but I was testing printing at 0.06mm later height. I have some slight ringing in the print but it came out fantastic. It looks better in person.by obelisk79 - General
Kevin, I have to say, reading the thread and understanding at least some of the planning, consideration and work that has gone into this I'm both impressed and gracious. I intend try this out on my RAMPS/MEGA setup some time in the next couple of weeks. Seeing this inexpensive hardware being pushed to higher levels of performance is both impressive and good for the community at large.

There are many ways of learning, social sharing, learning by trial and error and/or studying the science behind it all. Don't degrade someone for wanting to explore and experiment on a tight budget. I believe there historically have been plenty of incredible discoveries that have happened on accident? or with extremely tight budgets? All parties here have valid perspectives, I just disagree withby obelisk79 - Developers
I'm not an engineer, but the other question you need to ask is what kind of dynamic force is being applied to your belts while printing? This is something which is going to be uniquely different to each printer due to moving masses, print speeds, acceleration rates etc. I'd be more interested in proving if both belts qualify as 'good enough' I'd postulate that the answer would be yes.
