Quotelkcl how exactly did you publish them? 'git push' of the design files, no Gerbers.by Traumflug - RAMPS Electronics
Quotelkcl not publishing what you're doing also makes your life incredibly difficult. Yes and No. With Gen7 I initially published work in progress, too. The result was, people etched and soldered PCBs from this half-finished work and found it not working (as expected). Asking to read instructions is asking too much from average users :-)by Traumflug - RAMPS Electronics
Quoteobelisk79 NXP had apparently tried to discontinue the LPC1114FN28 earlier this year, but someone else had contacted them and they decided to renew production. That's good news! Another advantage of these genuine DIL chips over an adapter is that they're 5V-tolerant out of the box.

QuoteShank man I’m kicking myself for not buying a extra MCU when they were available Quoteobelisk79 That is an interesting adapter. So you two prefer to buy a $6 adapter plus a $4 chip over a $5 genuine chip? One reason against designing a new(er) board is the observation that quite a number of people try very hard and often at additional expenses to avoid buying from the original designer.

QuoteVDXpopulating and soldering SMD is doable in DIY-scale too, if using a stereo-microscope Microscope. Ha ha. Over time I got a number of comments expressing fear about this MCP2200 chip on the copper side of the Gen7, which is SMT. 1,27 mm pin pitch and fairly easily handleable with bare fingers, still people don't trust it. And these SOIC chips are rare, too.by Traumflug - Next Wave Electronics Working Group
Quoteobelisk79Will there be any updates to the design due to this? Good question. Swapping the DIL chip for a SMT (0.65 mm pin pitch) one is easily doable, but what's the point of a Gen7, then? Wherever I look I see requests for more and more complex controllers (Bluetooth, WiFi, 6, 8, 10 steppers, web server, ...), next to never wishes for simple, rock-solid, DIY-able ones.

NXP lists this part as active , so I'm not sure why they're out at stock on the major suppliers. MCUs in a DIL package going away would pretty much mean the end of DIY-able controllers :-/ That said, I have plenty of them, € 5.- a piece. Or € 22.- together with all other electronic components used on this board: .by Traumflug - Next Wave Electronics Working Group
Quote691175002 it just doesn't make sense to recommend 3d printer electronics for milling when there are alternatives which are more suitable for the task.

Quote691175002 Its the kind of stuff you might not notice if you've never seen it before Believe me, I've done this hundreds of times and never needed a tool changer or "responsive" jogging or cutter compensation or length offset or whatever reasons you try to find here for keeping people away from milling.by Traumflug - General

Quote691175002 I'm thinking more about work offsets, probing (not the z-bed kind), tool tables, etc... CNC without support for toolchange is extremely painful. I thought we were talking about milling here. Machines coming with a tool changer (what a luxury) most likely have a firmware already, no need to replace that one.

Quoteprot0typ1cal Machining away material [...] will need dedicated firmware. Not really. For basic CNC machining one needs (synchronized) G1, F and some spindle on/off means. Bonus scores for G0 and G92. All 3D printing firmwares I'm aware of support this. In fact, all of them are pretty overfeatured for something as simple as CNC milling.

QuoteVDX ... could be, the discussion in this thread is related too: You mean the topic "Why collaboration does not work"? Well, looking at the RepRap universe it looks much like it doesn't. The survey makers have a list of projects, too: I looked into some of them and found about the same: hardware is published ("Open Source"), but company-owned. Contributions happen on the software side.by Traumflug - General
Quotedc42 There are still companies and groups such as Duet3D, Prusa, Lulzbot and the Smoothie folks who are committed to open source. Not sure wether they're committed to Open Source ... or more to the success of their companies, taking the Open Source badge as a marketing item. Prusa and Lulzbot pretty much removed them selfs from the RepRap community and Duet3D, Smoothie are, sorry, well knoby Traumflug - RAMPS Electronics

Quotedc42 Do you have in mind a free-for-all in which anyone can commit anything? That sounds like a recipe for chaos to me. Picking up patches by 'git am', 'git cherry-pick' and/or merging all preserve the original author, so they stay visible. Regarding the free-for-all: Teacup does this and it works remarkably well.

Quotedeckingman The Duet is fully open source and based on the original RepRap firmware. That's certainly nice, but no help for collaboration at all. Yes, people do fork their own thing.

Quotefrankvdh What people are talking about is the *quality* of the board, not popularity. They *may* be correlated, but I suspect that price and popularity are probably more closely linked. Most likely true. Also, as others outlined already, most of the boards are no competition to each other. RAMPS is for the cheap, Smoothie/Duet for feature richness and Gen7 for DIYers.

I tried this already and v2.0 indeed got smaller (110x90, from 130x100), but further size reduction is hard because of all the components. These have to fit on top, even on a 2-sided board.

Quotegrimlok2000 open or closed source,what is different Interesting lack of knowledge. RepRap exists because it's open source. Before RepRap we had several decades of closed source, accordingly 3D-printing was pricey and without innovation.
