Here is a render of "RAMPS-FD3" from OSHPark which I tracked down on github. It seems that people copy projects on github instead of forking, which makes it harder to follow the evolution. I'm sure people aren't being malicious, just a bit careless and maybe ignorant of the GPL, but if we don't follow our own rules, it's a bit hypocritical to point a finger Eastwards and say "you guys aren't follby bobc - Controllers
I found some variants of FDv2 being sold on OSHPark. This is a surprise for a couple of reasons, 1) v2 is a beta and was not released either, 2) they appear to have violated the Open Source license, as they haven't published their modified source. I also recently found some of my source code has been literally stolen - they removed my copyright notice and put their name on. And these people are dby bobc - Controllers
1) That is tempting.I did some work on Decapede, having a larger board certainly helped to get a tidy layout for 10 steppers, 10 mosfets, a 60A fuse, and also segregating logic and ADC inputs. It is a big board though, and the Due is a bit lost underneath. I had some boards made in 2oz copper, but never got round to populate one. I would like to revisit that project sometime. Anyway, the layoutby bobc - Controllers
QuoteDust If you can make sure it works on a mega2560, why not just call it ramps2.0, its long over due That's a good idea! The latest RAMPS version on the wiki is numbered 1.4.2, it has a few improvements over 1.4. It might be hard to displace 1.4 - just looking at the prices on ebay, lowest price is about $5 including shipping. But it's worth trying!

Quotedintid I think I solved it everyone, I just need to figure out the firmware part You solved it? Well done When you write the instructable, make sure to put your name on it so you get the credit. BTW, it's engineers that are normal and sane. Non-engineers are the idiots.by bobc - Controllers
Board arrived today, v1.2 as expected. ETA, first impression is a well made board, with good quality components. Sensible PCB layout, the labels could be a little bigger, some are partly obscured by components, but otherwise looks good.by bobc - Controllers
I think a fresh name would be a good idea, since a new revision number is easy to overlook. The only idea I had so far is "RAMPS 2016". It's probably not widely known, but RAMPS-FD should also work with a Mega2560. I'm not sure if the situation with Geeetech could be avoided again - if it is OSH then we can't dictate who can make it. I think nearly all the actual problems I have seen reported wiby bobc - Controllers
On the github, there is V11 and V12... I am assuming that is v1.2. On the Makerbase website, they seem to have a photo of a v1.0 board. Either they gave you duff info, or they posted an incorrect schematic. They also post wrong photos... you still trusting these guys? Quite possibly there are counterfeit MKS products as well, the person from "MKS" is quite right, the clone each other's productby bobc - Controllers
Going from 0 RPM to 310 RPM in 1us, is a LOT of acceleration! I very much doubt you could get that performance from a reasonably sized stepper, you would need some huge torque. I would seek the alternative solution.by bobc - Stepper Motors, Servo Motors, DC Motors
Chris has it, there is an external module which plugs in. Schematic is here Page 14 shows connector J7, labelled THC. There are 3 signal pins, they go straight to the CPU. There is no amplifier anywhere on the schematic. The pins on the external module are labelled the same as J7. Now, you can believe the Chinese guy, but the evidence is enough for me... you will need to buy the module, unlesby bobc - Controllers
Quotedintid @arthurwolf Is the Smoothieboard 2going to have naitive support for Thermocouplers and/or PT100? Can the current Smoothieboard handle Thermocouplers without an external amplifier? Am a bit confused about this, as your documenation states we need an amplifier, but the chinese says I do not need one for their Sbase 1.2 board (and since they are copying yours I'm getting confused) Notby bobc - Controllers
The Due has some quirks with I2C. Have you tried adding delays? But you need to post more details, to the level at which someone else could reproduce your problem. i.e. what is the sensor what is the circuit (schematic) what is the version of Arduino IDE what make of Due What is the smallest sketch to show the problemby bobc - Developers

Hello everyone I'm gearing up for another round of development. It's time to bury RAMPS-FD v1, and find a way to get FD v2 out there. The No 1 complaint about v1 is the safety aspects, and I believe v2 fixes those problems. v2 introduces a few other things like onboard EEPROM, but is otherwise much the same.

I think that multiline proposal is complicated and anyway doesn't work because it still degenerates to the case where the buffer is full and the firmware can't accept a new command, so the host has to poll. The buffer size reporting adds complexity but doesn't add any value. I have a much simpler proposal, which is that the firmware simply returns "BUSY" for any command it can't handle immediateby bobc - Firmware - experimental, borrowed, and future

That's kinda what I heard. There have been a few attempts before to port Smoothieware to other platforms but they seem to fizzle out. Smoothieware is getting pretty big and rapidly changing, making porting a large task. The LPC4330 is a great chip, quite a complex beast though, it might take a while for that to appear with Smoothieware running. I have a LPC4330 dev board to play with, so I mightby bobc - Controllers
I'm not up to speed with the latest Smoothie developments, the best place to get advice for anything Smoothie related is their IRC channel : I believe that the Smoothie on a breadboard should still work, but may be a little out of date. Smoothieware continues to evolve, and support for the breadboard option may need updating. I think in principle Smoothieware should be able to support 6 driversby bobc - Controllers

I think there are several options for multiple extruders, either with or without expansion boards. The Duet is at the more expensive end of the range, although I am not sure it is good value for money. Another way to look at it is which firmware is best for Deltas, and then see what hardware that will run on.
