@Nophead I'm not surprised it is you giving them a go first, thank you for all the testing you have done in the past and in the future. @Cefiar Good questions.

I have tried 57600 with just as many errors if not more. I am using an official Arduino 1280 mega with the onboard ftdi chip. I bought the Arduino just for this purpose and it has only ever had Teacup on it and a Ramps board plugged into it.

I'm having a lot of corrupt data being returned to the host software, which then makes the host lock up. I've been using Ben's RepG and thought it was the problem but after a few emails and one patch for RepG that did fix initial connection problems I still get dropped o's from ok ALL the time.

Did you increase the speed and flow for the bridging or lower it? I would think increasing the speed to say 1.4 and the rate by maybe 1.3 should stretch the filament while the higher flow will lower the temperature.

Is that abs? I'm using PLA Is the cube hollow or solid? How many surface layers are you using? Are your bridge rate multiples in the speed panel of skeinforge set to 1.0 each as a starting point and both activate speed and add flow rate active?

@brnd Thank you for straightening that out for me (and likely others). It really make me wonder why the default settings in teacups ramps config is set as follows: /// used for G0 rapid moves and as a cap for all other feedrates #define MAXIMUM_FEEDRATE_X 200 #define MAXIMUM_FEEDRATE_Y 200 #define MAXIMUM_FEEDRATE_Z 100 #define MAXIMUM_FEEDRATE_E 600 /// used when searching endstops and asby Sublime - RAMPS Electronics
Your math looks to be correct and that does seem impossible but like I said it has acceleration, so it starts at 0 and ramps to 150mm/s but for only .4mm per z stage move so its just a burst of movement. I would imagine it does not reach the full speed in that short of distance. Any movement over 10mm will overheat the pololu driver running at 75%. I know how hard this is on the driver but I slowby Sublime - RAMPS Electronics
I know you say this is solved but I just thought I would add that your Z must be some what tight. Mine was tight and I had to limit the speed to 75mm/s until it was loose and now it moves at 150mm/s. The transition between layers is so fast that I get almost no ooze. It may only be possible because I am using teacup and it has acceleration. brnd pointed out these are actually mm/m (mm per minuteby Sublime - RAMPS Electronics

@aka47 If you copied your skeinforge profile using repg the new profile you created uses the old profiles prefs. I started with the sf39 thingomatic profile and copied it in repG but it was still using the thingomatic preferences found @ /replicatorg-00245/skein_engines/skeinforge-39/skeinforge_application/prefs/SF39-Thingomatic-baseline/alterations/ You will see a start.gcode andby Sublime - Firmware - experimental, borrowed, and future

One thing you have not mentioned is which skeinforge are you using in RepG: standard, 31, 35, 39. they are all included in repg245 by Ben and all do things a little different from the looks of it. Second thing is which skeinforge profile are you using, I am using 39 with a copy of the thingomatic profile which I have changed all the setting back to white/grey, turned off features in craft: chambby Sublime - Firmware - experimental, borrowed, and future

Micro-stepping isn't being used to get finer detail but rather to get smoother movement without vibrations. But this means to get high speeds without vibration you end up with really high pulse rate.by Sublime - Firmware - experimental, borrowed, and future

@jgilmore Having it at the side of the X axis makes a lot of sense and definitely makes it easy to implement. The only problem I see is my build plate does not cover my entire bed (sheet of glass clamped to the bed), the glass is the same size as the print area. So having it on a servo or manual cam near the head may still be better in some cases. @Architect If you are willing to take up spaceby Sublime - Firmware - experimental, borrowed, and future

I meant Z probe but it basically an endstop attached to a stick. Check out this one on thingiverse for makerbots, it uses a servo to get the probe out of the way when not being used but you could easily do that manually with a leaver as you only use it at the very beginning of each build.by Sublime - Firmware - experimental, borrowed, and future
I am not suggesting to use GRBL for reprap as it has been redesigned for milling in mind and has dropped all the extruder/heater code while adding lots of milling options, but rather that it could be used an example of how to implement the adjustable settings via serial command line. And as Markus pointed out it does implement a 20code read ahead which could be useful as well. I am playing with iby Sublime - Firmware - experimental, borrowed, and future
Why not use a Z prob attached to the print head so that when it is .2mm from the bed regardless of where it is on the lead screws it will stop. You will never need to adjust the end stops again, you can use a 25mm thick bed or a 6mm thick bed and it does not matter. Plus no need to ever change any settings in the config.by Sublime - Firmware - experimental, borrowed, and future
Call ultimachine, they just received a complete set on Tuesday that had been lost in the mail to me for the last two months, they may still have it in stock. Also they do have both opto and mechanical endtops even if the web site does not say it. JUST CALLby Sublime - RAMPS Electronics
@AK47 have a look GRBL it allows you to change your steps per mm/inch, max speed, acceleration, arc segment size and more from the serial terminal and it is based on the original reprap G code interpreter. So it should not be to hard to take their example and implement it in Teacup. It currently supports all standard Gcodes for milling, It supports arcs and has acceleration while still fitting onby Sublime - Firmware - experimental, borrowed, and future
You could also just put some jam nuts on the threaded rods and make a physical stop for the z stage. Once the z stage hits the nuts it will simply stall the motor.by Sublime - RAMPS Electronics
