I'm having the same problem, where each time the extruder starts for infill it extrudes too much before starting motion. I think the problem may be in the reversing algorithm that Reprap Host uses. There are three tunables involved, Reverse, DelayForLayer, and DelayForPolygon. Even with all but Reverse zeroed, I still get too much ABS laid down. The algorithm Reprap Host uses is to run the exby srwalter - General Mendel Topics

I ended up building a direct-drive pinch wheel extruder for my Repstrap. Now that I've printed a set of mendel parts and built that, I attached your exutruder to it. Works great!by srwalter - For Sale
Update: I switched from an MDF bed to an acrylic bed. Using the acrylic bed + "aprons" at the corners helped significantly.by srwalter - Reprappers
I'm printing with ABS onto blue painter's tape. I don't have a heated bed, so I'm getting a fair bit of warp. However, the problem I have is not that the plastic lifts from the tape. Instead, the tape peels up from the MDF bed. I expect some warp using ABS without a heated bed, but I was under the impression that other people were using a similar set up with moderate success. Can anyone eithby srwalter - Reprappers
It would probably be easier to create a new branch for the release code, since it will be older than what's already on master. Otherwise you'd have to rewind the master branch, and rewinding in a public repo is frowned upon. I think you want something like: git branch release a0543d33 git push github release:refs/heads/releaseby srwalter - Firmware - experimental, borrowed, and future
Excellent find! I've had to switch to Sun Java as well, but it was before this particular project so it didn't occur to me...by srwalter - Reprappers

One other crazy thing I had to do was to change boards.txt so that the "upload.protocol" was "arduino" instead of "stk500." I'm not sure if that was the exact error I was seeing or not, but it's worth a shot.by srwalter - Reprappers
If you look at the lines around Extruder.cpp:19, you'll see something like "#ifndef ATMEGA168." You should be able to add the 'P' there to get around the check (or just comment out the #error, you know what you're doing now :-))by srwalter - Reprappers
Excellent, you've definitely got the bootloader on there now. Sorry about the :m, I should have had that correct. Strange that changing boards.txt made no difference. I'm not an arduino expert so I'm not sure where else you might have to touch. If you remember the files you had to modify to get the 168P working initially, it is surely one of those files. Good luck with the Gen6 electronics!by srwalter - Reprappers
It looks like it may not have burned your fuses correctly, which is extremely important as I found out the hard way. Not sure what to recommend there, you may have to google for that. I suspect boards.txt is what needs to be modified to fix the capital 'P' Hope that helps!by srwalter - Reprappers
Yes, since you ordered the CPU as a component it will have been blank. I find the arduino IDE essentially undebugable, so let me give you some instructions for directly running avrdude. Are you using arduino from apt-get or did you download it directly? If apt, go to /usr/share/arduino, otherwise go to the extracted arduino directory. You should see the file hardware/arduino/bootloaders/atmegby srwalter - Reprappers
1) That module should work fine. As long as it outputs 5v and has all the standard RS232 lines (and it appears to) then you should have no problem. Do compare the pinouts to what's on the wiki, in case they are numbered differently 2) Step 1: plug in USB module. Step 2: there is no step 2. You Windows people always over-complicate things 3) So you bought a pre-built extruder board? If soby srwalter - Reprappers
