I didn't realise that others were contributing to this thread! Well, anyway, I've just completed the build and now have a dual head (dual X motor). I'm using the current version of Marlin from GitHub and have configured it for Dual X in the Configuration_Adv.h file. I have some other issues at the moment but I see that there is no native support for the second Extruder and X motor in the LCD menuby MotoBarsteward - RAMPS Electronics
I understand what you are saying. Only problem comes when you have a gap between the top of the support layer and the underside of the thing you are supporting due to rounding error. Say, for example, your layer height is 0.15mm and your supported layer is at 0.45mm. You only have room to fit one layer of support in, 0.3mm, so you have a gap of 0.15mm between top of support and underside of suppoby MotoBarsteward - Slic3r
Do you have a spring beteen the the X-end and the top nut? the idea is to have tention between the top nut and the bottom nut to remove backlash and to ensure the bottom nut always stays in the x-end.by MotoBarsteward - General Mendel Topics
Yes, I know about this feature and use it regularly as me usual layer heigh is 0.15mm. I set up the infil to infil every othe rlayer. In the case I have now, I have not done this and I was expecting the support material layer heigh to be the same as that of the object. It is not. There is no way of controlling support layer heigh independantly of actual object layer heigh so either slic3r is chosby MotoBarsteward - Slic3r
Just playing with the latest version of slic3r built from the stable branch particularly support material generation as my dual head printer is almost complete. Is it correct that the support material appears to be with a double layer height of the object tht it is supporting? I did delete all ini files before slicing?by MotoBarsteward - Slic3r
Did you raise an issue in GitHub? The main chap who writes Slic3r doesn't read this forum that often so he may not know about the issue.by MotoBarsteward - Slic3r
Yes, I realised this and removed my perl installation, replacing it with 5.14. At the time, that made no difference. I have managed to get it build subsequently by manually applying someone else's fix. That fix is now pulled into Master and Stable branches so things should work 'out of the box' but ive not tried recently. But your quite correct, slic3r is only supported using perl 5.14.by MotoBarsteward - Slic3r
With what material are you printing? PLA? Try using a fan. Bridging is a point of weaknes with this printing technology so you will always have gaps between threads on the first layer of a bridge but the layers get better when printed on top of the bridging layer.by MotoBarsteward - Slic3r
I think I can shed some light on this. I've suffered from the same thing where I change settings but they don't get saved. I normally work in windows but was forced to use Linux the other day to try a build on the stable branch. Under Linux, with some control boxes, Slic3r crashes if you select and delete the content, i.e. end up with an empty text box at some point. At the command line, one seeby MotoBarsteward - Slic3r
I moved over to RC1 and then RC2 to fix other issues I was having only to find that they have introduced problems that make Slic3r useless to me. I find that If I print big things the slic3r gets confused and thinks that holes are things and turns the object inside out. From the commits, I can see that these issues have been observed and fixed but I can't build slic3r from github to try this out.by MotoBarsteward - Slic3r
I'll raise an issue in GitHub as the build instructions are not correct. -> Issue #1681 raised.by MotoBarsteward - Slic3r
My build is failing. This is a brand new clone and build on this machine. It is failing during ExUtils-typemap. I've attached the log file. I could delve in to fix this but I suspect it's an environment issue rather than the code being broken. I'm using CitrusPerl 5.16.3.18 and windows 8.1 32bit and think I've followed the instructions in the wikiby MotoBarsteward - Slic3r
Only one head is used at the same time, the other being parked. I'm not so much interested in multiple colours but in printing support material that can be remove my soaking in water or Limonene. The latest stable Marlin already supports this, I believe. If not, I'll branch it and make the mods required.by MotoBarsteward - General Mendel Topics
Has anyone else done this? I've been working on this for a year now, off and on. I now have some PVA and, more recently, so HIPS. Hoping to use these as soluble support material, I needed to modify my ABSPrusa to have two print heads. All I've done is to lengthen the X-axis and modify the X-end to have both an idler and a motor mount. In the past, I've always used PLA but experiments have shownby MotoBarsteward - General Mendel Topics

Maybe Bre Pettis was 'advised' that MakerBot were infringing Stratasys' patents and was 'asked' if he would like to settle their claim without resort to the courts?

Also, check that you've selected thermistor type 1 in the Marlin configuration.h file.

Solved... By chances, found out what it was. I want to use the firmware controlled cooling fan. As I intend to use the E1 extruder at a later date, I thought I could control the fan using the first servo output on the Mega2560 shield. It turns out that when the fan is at any other value than off or 255, it screws up all the stepper motors. I have built the mostfet driver circuit for the fan so Iby MotoBarsteward - Firmware - mainstream and related support
The video seems to show that it can keep up. Anyway, the maximum print speed I have configured in slic3r is 60mm/s. When I ran with the sanguinololu, it was OK. Thanks for the suggestion, though.by MotoBarsteward - Firmware - mainstream and related support
OK, realised that I was using the latest github code on the Version 1.0.0 branch so swapped it for the tagged version referenced in the Marlin RepRap wiki page. Made no difference. I also have a video of the stutter. Here it is shown in the extruder but the same thing happens in the other axis.by MotoBarsteward - Firmware - mainstream and related support
I've taken some videos to help explain what I am seeing... I ran some tests to check that it was not the case that I was just trying to go too fast. I ran a test script gcode file, attached, to get the printer to slew around. The rate for all moves are F28800 or 480 mm/s. This video shows that we have no trouble keeping up. I then printed the attached gcode file, shown in this video which showsby MotoBarsteward - Firmware - mainstream and related support
Nope. Made no difference. However have noticed that when I stop the print, the manual movements are very jerky. They were smooth before I started the print. I suspect that when the Marlin starts to print the traces with the higher feed rates after the first layer there is some software overflow which is screwing things up. Can someone please take a look at my configuration files?by MotoBarsteward - Firmware - mainstream and related support

I have just completed upgrading my control electronics from Sanguinololu/Sprinter to Ramps1.4/Marlin and am having problems printing. The problem occurs with gcode sliced with old and new versions of slicer. The first solids layers print perfectly as they did with my old hardware/firmware.
