If you decide to go dual consider biting the bullet and making it dual X carriage (vs having both hotends on the same X carriage). Something like the previous poster showed or this: http://www.okob.net/projects/reprap_x2v3/default.htm instead of this: http://www.okob.net/projects/reprap/default.htm The firmware changes are all there.

I've pushed to branch "lcd". If your LCD controller worked before, then likely we have different ones and the settings from your config file is what you'd still have to use. The controller I use currently (and the config files/code on the branch are tweaked for) is "full graphics" smart LCD controller from reprapdiscount. Those compilation errors you saw should be fixed anyway since the menus iby dob71 - General Mendel Topics
I'm using the same LCD (got it working recently), but getting it worked required a bunch of changes. It works ok and supports a lot of the multiple extruder settings of the firmware, but I'm still poking in the code trying to make a few improvements. Will push what I have later today to a branch and post here.by dob71 - General Mendel Topics
Hi Geert, 1. Let me start with the easy one, the duplicate printing: - M322 - Turns the "follow me" mode on or off for an extruder (parameters: T<extruder_number> S<1-on/0-off> ), it's automatically off for the active extruder. If used without S parameter the command prints current settings. If used without T parameter applies to all extruders. Basically, the steps for dual printinby dob71 - General Mendel Topics
Hi Jesper, Checked your Prusa i2 mod. Great extruders. Looks like despite motors and gears they allow hotends to get very close. Detailed build instructions for those would be nice. BTW, my experience with covering the idle extruder nozzle (especially when printing PLA and large objects) is that the plastic liquifies and pours down inside the hotend. That creates an initial splodge followed bby dob71 - General Mendel Topics
Hi all, I'd like to share a design that came out from several years of developing and using dual extruder machines. The main use case has always been printing with soluble support and that's finally (after water soluble PVA failures) seem to work for ABS/HIPS combination. Dual color and simultaneous printing of the straight or mirrored (RepRap X2V3 only) copy of the object is a nice bonus. Thby dob71 - General Mendel Topics

Each extruder has its own motor. That machine was similar to the one pictured on top of the post (you can see the motors there). Note that it was made a year ago. I'm currently using separate X-carriages for each hotend: http://www.youtube.com/watch?v=AEW-DNo0GxIby dob71 - For Sale

Sorry, missed your question (aparently I wasn't getting the post notifications). The way I'm developing RepRap X2 is more like the software development. No rebuilding of everything fom scratch, just trying to reuse as much as possible by gradually upgrading.

It is a known fact that too many options and choices can make people give up and choose nothing. A page simplifying the decision making for someone new might help. I'm not sure it is going to work though as that page will become just yet one more option for someone new to consider. I tried to do something like that in the software area.

Another variation to add: RepRap X2 Dual extruder version of Prusa's Mendel. Links:by dob71 - General
Here are the results of a few experiments with lowering idele nozzle temperature when printing with 2 extruders. The PLA oozing was pretty much eliminated when temperature of the idle nozzle was lowered 40 degrees. The "parking" object solved the problem of oozing during the temperature change. It is quite time consuming though. Here are the pictures comparing results of printing the same test oby dob71 - General
The problem is that retract doesn't remove all the plastic from the nozzle area in the hotend. PLA also stretches a lot inside when retracting. Even though there is no more pressure the remains are still oozing through the nozzle. ABS is better in this regard, but I'm interested in printing PLA w/ PVA support and both of those appear to be prone to leaking regardless of the retract. The experimby dob71 - General
Here is the situation is I'm trying to deal with. When extruder 1 is printing extruder 0 is slowly leaking PLA. Let say it takes a minute for the extruder 1 to print its part of the layer before extruder 0 has to start printing its own. In that case it might be better to lower the extruder 0 temperature about 30 degrees down while the extruder 1 is printing and then reheat it back before it is itby dob71 - General
There are a lot of commits and small improvements in the standard Marlin, but I didn't yet see features that would look valuable enough to do the merge. They are still working on the same version of the code my changes went into. I'll probably do the merge eventually when they release from Marlin_v1 or better they might pull in the changes.
