Fixing Pulley Innacuracy

[foehnsturm 969]

Hmm, mainly for two reasons:

I was looking for a drop-in replacement as simple as possible. And because I will get best manufacturing quality for the same price tag or less, compared to GT2, 20 teeth, 8 mm bore pulleys (of whichever quality).

Up and running. Belt tension remained quite similar.

Outer dimensions used to be 19.7 to 19.8 mm with the standard setup. Now they are 19.9. Which makes me think that the printhead movement might respond better to the fast +0.1 mm / -0.1 mm stepping at the corners.

Yes, I take a set of 12 as well. Let me know when you had a chance to make up your mind about price&delivery :smile:

If you sent me your paypal email address via PM, you get the money right away

I'd be interested in a set too. Some of my original UM ones have the bore distinctly off-center.

 

[snowygrouch 1]

Me too....consider this a "pre-order".

Count me in, too.

 

[fluxline 0]

yup, me too

I will fix production details and the final pricing next Monday.

Switching back to one M4 thread and re-using the grub screws might be a good idea. I'm using just one screw now and tightening two screws / pulley during adjustment seems to be cumbersome. Other opinions?

Is there interest in 5 mm bore / stepper pulleys as well?

 

[edis 0]

of course, i would be interested in buying full set 8x8mm bore and 2x5mm bore

 

[snowygrouch 1]

If you can I think 2 screws is better, how often do you need to adjust yours ?

Except when I am modifiying something, I have adjusted them about twice in 6 months...

If you can I think 2 screws is better

 

Agreed. I'd probably purchase a set with the two grub screws as well...

[joergen 2]

Thank you so much for the offer.

Anybody in for a combined shipment to the USA, to make it easier for foehnsturm? (ship one large box to the US, and I (or somebody else) breaks the order into smaller USPS flat rate shipments). Illuminarti, up for it? who else is in?

 

[joergen 2]

Ultimaker pulleys:

 

• [*]two m3 threads with grub screws

 

 

 

Quick question: why M3? I thought the original UM has M4 with a 2mm hex driver size? Or did I got that one wrong? (If M3 works fine, than ignore my question/comment please)

 

[foehnsturm 969]

Thanks Joergen.

My fault, it will be M4, same as original UM (i've just edited the original post).

 

[francis 0]

I'd like a full set (10x8, 2x5) also. Will send you details.

Thanks.

Hi,

I am a total Noob here and at the moment I am building my Ultimaker.

Having just assembled the axis and given it a good look over, several of my pulleys are visibly wonky!

Please put me down for a set of 8.

Cheers

Bob

 

[IRobertI 516]

Eh, what the hell, put me down for a set of 8 (8 x 8 mm) too Certainly couldn't hurt.

 

[illuminarti 18]

Hi Joergen - Sorry, totally overlooked this thread for a few days. Yes, I'm in. Sounds like a good plan.

Great.

For all US orders/customers who like to order pulleys, make your payment for your order to foehnsturm, and leave a comment for him to ship it to me (NYC). Once I received the bulk order from foehnsturm, I'll repackage into small, flat rate USPS boxes, and sent the pulley's your way within 1-2 days.

 

[lars86 42]

Not sure why I didn't see this update. I'm in on the US group shipping. How would you like to handle payment foehnsturm?

 

[gadgetfreak 7]

Hi Markus,

I would really like two full sets also if it's not too late?

How would I pay, by paypal?

Is there any chance you will be at the 3D printing FabCon fair in Erfurt, Germany?

I'm not sure where you are at!

I'm going and I'm from Sweden

Thanks a lot in advance,

Daniel

@Lars86

Hi Lars,

8 X 8 mm & 2 x 5mm? I will place you on Joergen's combined shipment. I would like to use Paypal and will send you a message when the pulleys are ready to dispatch.

@gadgetfreak

Hi Daniel,

two full sets is o.k. I'm from Germany (Munich) and I'm afraid I won't make it to Erfurt. My (main job) customers have their big event, the LASER 2013 fair, at the same time.

@Alexander Baloche

Hey, good to hear from the Ultimaker team. I put you on the list. It's my conviction that there are local companies, which can provide high quality for a competitive price.

Markus

 

[gadgetfreak 7]

Thanks Markus, that's great!

Will you PM me with your paypal address?

Do you want me to PM you with shipping address?

Whenabouts do you expect them to be ready?

Please send me a set of 8, too.

Attach me to the US shipment, if possible.

PM me with payment details.

Thanks!
