Modicum Extruder - New belt drive extruder design. V1

[jaguarking11]

I designed a new extruder.

The goals for this extruder were/are

1 - size (must be small)
2 - Lash (must have as little as possible)
3 - Cost
4 - Easy to manufacture
5 - Torque
6 - Must be able to push flexible filament through


I went through many iterations and tested out allot of my designs by printing and installing them on my machine.

This is the end result. I think I did rather well on this one.

The design looks nice. I'm in the middle of figuring our a new dual extruder setup for machine and was looking into a few of the belt drive designs around the interwebs. Do you have a link to the BOM and STL files so that I can take a look?

[dunginhawk]

if you are looking for someone to test it in the field id be willing.. im always struggling a bit with flexible filaments, so ill always look to improve pushing them through.
thanks

[jaguarking11]

I have not tested this with flexible filament just yet. However it was designed with flexible filament in mind. As of now I am not yet comfortable with sharing the STL's. I will do so when I feel this thing has been put through its paces. I plan on selling these in small batches soon, I would like to fund my next project (Micro delta printer) with these.

As for running dual filament, I could make a design that would integrate two of these together. However I feel having them as single units is much more adapt and lower cost to the user.

I would be willing to buy one of these for a reasonable price, knowing its first off the line and offer my feedback.. but yeah, keep us posted, im very interested.
thanks

I will keep you guys posted. I will be ordering parts to make 10 of these this week. Having a bit of a supply problem with the 5mm hardened shafts I am using. The manufacturer is out of stock.

I completely forgot I had this thread here. In either case I open sourced my extruder and was featured on youmagine.

I am also selling a few of these. I built 3 green ones as of now. I sold 1 already. Here is another link. -> http://www.ebay.com/itm/151610555692?ss ... 1555.l2649

This is the last link to my blog concerning this thing. -> http://engineerd3d.ddns.net/modicum-v1-open-source/

What do you guys think?

Hi
I want to order the extruder.
do you have it on stock? Will it fit to the max V2?

Please advise

[jaguarking11]

I do have one in stock. Its also green. I will be printing some black extruders soon. They are made in ABS. Send me an e-mail to [email protected] for further details. One thing to keep in mind is that at the time I am only shipping to US.

I am also interested in the extruder and would like to see more pictures at different angles so that I may understand where the stepper is, etc.
If you are maintaining a list of people who would like one please add my name to the list. You can use our PM system to contact people privately.
Thank you for sharing this and hopefully this can grow to be more than just a hobby.

The only pics I have are on youmagine. https://www.youmagine.com/designs/modicum-extruder-v1

I believe the user above will purchase the last of my pre built units. I will manufacture more of them in the coming days. Out of curiosity, do you guys have a color preference? In either case. Feel free to e-mail me and I will work out the details. I am selling these for 60USD shipped in the US fully assembled with a pigtail on the motor. You just solder the wires and add two screws and mount it.

Thank you for the support guys.

I would buy one if it was in black rather than green

[jaguarking11]

I am printing black ones in the coming days. Stand by and I will update you guys.

Just let me know when it's available - consider one of the black ones, sold.

Hi.
I really want to order it even the green one. Is if possible to ship it to Israel?

[jaguarking11]

I will see what I can do about shipping to israel. However I do not have much experience in shipping outside the US, and some parts of europe. I will see what the calculated costs are.

[mvansomeren]

When do you anticipate the black versions will be ready?

[jaguarking11]

I expect to have them ready by the end of this week. I wont list them on e-bay this time. I will contact you when they are ready.

Perfect!

By the way, what is the drive ratio?

[jaguarking11]

Drive ratio is 2:1 on this batch.

[mvansomeren]

Thanks.

[mvansomeren]

Any updates?

[jaguarking11]

I just finished this batch last night. I have been going through a printer upgrade the last week or so. Everything from the hot end to the arms to the bearings to the carriages and end effector have been upgraded. I even added a DC-DC power converter to my bed to overdrive it and make it heat up much much faster. In either case. Send a PM if you wish to purchase one of these.

[mvansomeren]

Payment sent. Looking forward to trying it out.

[jaguarking11]

Thank you for the patronage.
