Re: Printing With Dual Extruders - My Early Lessons Learned

cjdavis618, I must "retract" my endorsement of Cura 14.02_RC5. It still has many bugs in it that have yet to be worked out. Cura 14.01 is a stable performer (once you remove the last line from the g-code). But the bugs in RC5 make it too scary! Don't use it...yet. I have just completed a n...

Re: Printing With Dual Extruders - My Early Lessons Learned

Daid has posted Cura 14.02_RC5. This appears to solve a number of Mac build problems. It appears to be working well on my Windows 7 machine.

Re: Printing With Dual Extruders - My Early Lessons Learned

Daid has published Cura 14.02_RC4. The erroneous moves noted in my above post have been corrected. There are many features in this beta version that have great promise. You can find Cura 14.02_RC4 in a post on the Ultimaker User Forum ( http://umforum.ultimaker.com/index.php?/page/index.html ). Join...

Re: Printing With Dual Extruders - My Early Lessons Learned

Oops! I misinterpreted what happened to my Rostock MAX in my post immediately above. I was trying the beta version of Cura 14.02 and the slicer is generating travel moves that want to take the hotend well off of the build plate. Look at the 4th line in this code snippet: G1 F420 X-96.56 Y7.33 E15.61...

Re: Printing With Dual Extruders - My Early Lessons Learned

Here's an interesting and important tidbit of information. When you install dual hotends on a Rostock MAX you effectively reduce the printable area of your build plate. We are used to typing in a radius of 190mm, or a build plate that is 280 X 280 (depending on the slicer). And then we go on and gen...

Re: Printing With Dual Extruders - My Early Lessons Learned

Hi, Gene. Yes, I'm running RH 0.95F (e-i-e-i-o :D ). Version numbers make me a little crazy. It's not a missing G28. It's that long profile comment stored as the last line of the gcode. Daid just released a beta of Cura 14.02 (e-i-e-i-o) yesterday(?). And there is some mention of "fixes" t...

Re: Thinking about buying KISSlicer? Don't.

As is said above, no one knows what has happened to Jonathan. Prior to September his slicer and support forum were developing well. Then all of a sudden... The slicer is lagging behind others now (IMHO). And we will see others continue to evolve ad offer very nice alternatives. I hope Jonathan retur...

Re: Printing With Dual Extruders - My Early Lessons Learned

Now that I have slept I remembered there is a big problem using Cura 14.01 with a Rostock MAX (well, really with Repetier Firmware). MSURunner covers the issue in this thread: http://forum.seemecnc.com/viewtopic.php?f=54&t=4119&p=27290&hilit=Cura+Rostock#p27290 . The Cura Engine is writt...

Re: Printing With Dual Extruders - My Early Lessons Learned

Here's a big issue that has to be managed with dual extruder printing, "drool." Yep, drool. If you have ever printed with ABS and left a heated extruder "idling" you have seen how the ABS slowly "oozes" out the end of the nozzle. When you are printing with two extruders...

Re: Printing With Dual Extruders - My Early Lessons Learned

Thanks for your thoughts, guys. This Rostock MAX thing continues to be an adventure. Moving on with what I have posted so far, it is important to note I call the left hotend "Extruder 1" and the right hotend "Extruder 2." Take a look at the image that shows my "Machine Setti...

Printing With Dual Extruders - My Early Lessons Learned

Hello to all, I have been working to align/calibrate my dual extruder Rostock MAX for several days. I have been using Cura 14.01 as my slicer for the test parts, and have been printing with black ABS and natural HIPS (used as a "dissolvable" support material). The part I have been using fo...

Re: Dual extrusion how-to

Following are photos of my first dual extruder print. The two parts of this design are a hollow box (printed in white) measuring 20mm X 20mm X 20mm; it has 1mm thick walls. The other part (printed in blue) is a square tube measuring 20 X 20 X 20mm with 1mm thick walls. I sliced the .stls with Cura 1...

Re: Dual extrusion how-to

I have a print running using both extruders! What a Rube Goldberg-sounding machine this is! Incredible. The print is a two level, 20mm square hollow "tube." The walls of this design were developed 1mm thick so I could get a real good sense of alignment errors; I can already see that my X o...

Re: Auto-Tune and Dual Hotends (?)

Thanks for the reply, Eaglezsoar. But, alas and alack ( :roll: ) the E1 entry has no effect in the M303 command (at least with my present firmware it doesn't). All of the g-code references I found (eg, http://reprap.org/wiki/G-code ) do not provide a method for selecting a specific extruder. What am...

Auto-Tune and Dual Hotends (?)

Hello to all, I have my dual Steve's Extruders mounted on my Rostock MAX and, after correcting a pair of really strange pin #defines in calibration.h (Repetier .83) I now have all of the hardware working and responding to manual control. After getting everything working, I ran Auto-Tune in Repetier ...

Re: Dual extrusion how-to

I have my dual head configuration installed and am beginning tests. My new Z height appears to be 319.95mm. So, I gave up roughly 40mm of Z height by installing my hotends this way. There is no appreciable difference in the Z positions of the two nozzles (i.e., they are at the same height). By the w...
