Another rostock max build

[foshon]

here is the mount for the pg35l extruder.
This version mounts the direct drive extruder underneath the rostock platform. vs the top as shown on this thingiverse link http://www.thingiverse.com/thing:43457

Are you going to post that stl? Please? I used thing:39966 and I am not impressed. Your's looks like the ticket.

[cambo3d]

Will do , once everything is everything is fit up properly.

Edit :Brad from ultibots posted this file Today. You can find it on thingiverse. http://www.thingiverse.com/thing:87028

its the same one i had him modify for me.

[Eaglezsoar]

Cambo3D, how do you find the time for all the things you do?

[cambo3d]

I don't know really, when I start project, I don't stop till I'm satisfied with the results. Usually this means late nights and long days. When I have downtime waiting for parts to arrive, i'm still working on the computer drawing up ideas for other projects, checking designs getting ready for production run... I just fit in whatever I can do, when I can.

Just trying to gauge how many people would be interested in this. I have a proto type made as you can see from recent post. http://forum.seemecnc.com/viewtopic.php ... 340#p11917

Originally made this for my own rostock but I've had a couple people interested in it also.

so I'm wondering many would be interested? What you guys think a reasonable price for this would be? If there's enough people interested, I may be able to swing it.

I'd totally be interested in a machined magnetic joint solution. Would you also have machined parts for the cheapskate side?

Personally, what I'd be willing to pay would depend on what was included, i.e. cheapskate ball mounts, mounting hardware, magnet cups, etc. Basically it would depend on how much work I'd have to do to get it up and running.

That machined effector looks great, btw.

Put me down as interested. Price can only be determined by you because we have no way of knowing the cost of materials, time invested, and profit.

I know what my cost are, just wanting to see what people are willing to pay. I'm trying to work opposite here by starting off with what people are willing to pay then do what I can to get it within you guys price range.


apache, I have an idea for the carriage side, i'm still working on and testing.

[dbarrans]

You milled this, right? Can you laser cut it instead? Would that save some cost?

I'd pay $20 for it. Maybe a bit more. Someone has to throw out a number to get started. If it was part of a kit that included a solution for the carriages, I'd pay more. How much more depends on how much I still need to do myself.

I've started collecting parts for something, but haven't yet worked out how I'll machine what I need. So far I have the magnets, some 1/2" balls, and some delrin rod. Probably going to use carbin fiber tubing from dragonplate.com.

A laser cutter capable of cutting .125" aluminum is veeeery expensive. I'm sure he'd be happy to cut you one if you supplied the laser though!

[cambo3d]

I dont have a laser cutter Dan, but i'll see what I can do about milling these out at a lower cost but $20 wont even cover the cost of the tooling. Unless there are more people interested.

[cambo3d]

some more progress on the all aluminum magnet joints compatible with seemecnc parts.

testing fit up

little more than a pound of weight

[cambo3d]

test fitting all aluminum hot end mount prototype . compatible with xnarons conversion.

[Schneider]

Well, if you plan of selling a complete kit, i'm buying. I'm pretty sure i'll eventually be able to make mine work..i think!

[Eaglezsoar]

Cambo3d, I am confused how your effector works. Xnaron's mount the balls at an approximate 30 degree angle,
yours appears to be flat. How has the testing gone on your aluminum version?

[cambo3d]

Preliminary fit up of the bottom mounted direct drive extruder. the hole for the filament is not in the center but i'll try it anyway till that gets fixed.

compared to the weight of stock stepper of 332grams. this weighs about 226grams, around 240grams with the magnet ball joints installed. not to much lighter but with all the fans/heatsinks installed it should still be under 300 grams.

will need to modify the extruder mount and reprint so the hole is centered. or modify the aluminum affector

dont think i'll be selling kits, just some parts I make.

the angle of the balls helps with clearance when at the extreme ends of travel. but looking at the design i dont think it will interfere. i'm still testing and fitting up at this point

[Polygonhell]

You'll almost certainly need a heat sink on the PG35L, and possibly a fan which will add to the weight a little.
Are you intending the bend the mounting points as seen on the BerryBot, or are you going to have it remain flat?

Planning on keeping it flat for now. Will know better once its all fitted up.

doing some research on these little motors. they seem to be unipolar, instead of bipolar. our controllers are bipolar type, I think.
Is this why this motor runs hot?

[cambo3d]

I've been brainstorming on how to mount these http://forum.seemecnc.com/viewtopic.php ... 320#p11149 hall effect switches.

I have some so so ideas but wanted to see how you guys would do it. Maybe help me come up with a better solution.

[dbarrans]

What have you come up with so far? Maybe we can embellish it.

[ApacheXMD]

Sensors look like they're panel mount, so I'd print a panel for it to mount at the top of the towers. Secure panel to side of tower with t-slot nut and bolt, since cheapskates don't go all the way up the tower it shouldn't hit. Then print a magnet mount that takes a 6-32 screw so it can screw in stock hole where the end stop screw goes.

hmm working out the the fit..but i came with up something that mounts it to the outside of the frame. while keeping the stock switch in place for now.... for testing purposes.

[cambo3d]

some eye candy. continued from here. http://forum.seemecnc.com/viewtopic.php ... 360#p12644
got the heat sink, fans and some 3mm filament in today. Looking good to so far, I should be getting the 3m epoxy dp420 adhesive for the mag joints also and I'll be almost ready for test run
