E3D on Da Vinci (Page 6 of 9)

I didn't replace the screw,  but I did remove and straighten a few bends out of it when I first started playing with this machine.

My machine was a demo unit so it's early life wasn't all that easy.

I shipped my hot end to my folks place so I wouldn't be distracted for finals. They lost it....

Pretty much my exact reaction lol

I haven't had any experience with that particular gear. 
But I have had some experience ruining steppers trying to remove gears.
Since the gear on the DaVinci extruder doesn't have any set screws one would assume it's epoxied on or something.
Trying to rip it off may cause the central shaft to be extracted from the armature.

Be warned.

I'm running this mod and use the little 623z skate bearing recommended with the mk7 idler.
Go to page 3 and you'll see the details.

To make changes unless they can be done through the EEPROM configuration you have to open the firmware in Adruino make the changes, then compile/verify and upload it to your board.  The only change I see that needs to be made form my observation and future update is the bed home setting which will be much lower due to the increased length of the E3D. I was simply planning to use a piece of electrical tape stuck on the mack or the bed support where it goes in to the home end stop. The tape would extend the height of that back piece to compensate for the added length of the head.

Ok, I know it's a bit stupid question but where does it exactly go (z-axis extension)? All the pictures I have seen in this thread are without it.

I would use sigmaz method if I were you. The Z-home extender is great until your bed tries to drop all the way to -210 that the firmware says it can go to when you actually only have ~180mm of travel. Just a thought. I would really consider changing the values in the EEPROM or using sigmaz method.

I will keep all that in mind once I will get around installing the e3d. This week has been all about switching from stock firmware to Repeater and getting to know it. So far I'am amazed, with Reperter the printer is much quieter and the quality is much better as well.

Just posting to say that I've finally gotten everything except for the random screws and such I'll need (probably hit up Lowes or something to get them).

At this point, I have most of the parts modified to fit together properly. Everything looks good, so since I have off from work for the next week, it's time to work on this a bit.

Judging by the down sides of the current mounting method, I think once I get this working I'll probably work on making a setup that doesn't have the loss of z height in printing.

Do we know who designed the original found here? http://www.thingiverse.com/thing:473038

It would certainly be easier to start with this base and modify it, but I'm not sure what was used to generate the files. Anyone have any ideas?

My da Vinci 2.0 is still completely stock and I'm just about to start upgrading it. I received the E3D v6 (Bowden) and hopefully I'll have time to do the upgrade in the next week or two. I just ordered the 623 and LM8UU bearings.

Has this been done on a da Vinci 2.0? Sorry if I missed it, but if it exists can someone point me to the files I need to print to keep the two nozzles at the same elevation? Last I saw the 2.0 mentioned was in October.

When you guys refer to the MK7 idler, do you mean the 623 bearing? Are you using the original extruder gear that's glued onto the stepper motor? Is the MK7 or MK8 a recommended extruder gear upgrade? I don't want to be limited in material selection. Outside of this thread, I haven't seen much about the MK7 on da Vinci. Any threads I should read?

Thanks!
