Are you sure? Cause I followed the instruction video showing him inserting one mini-v precision shim on one of the sides of the wheel.



Look at 1:24 in the video. Looks wierd I agree, but I suppose that one bearing is offset 1 mm because of the shim.

Took additional pictures of the mounted wheel. I also tried flipping the wheel to see if it helped, but it didnt.

 

No, I'm not sure - I don't have a belt drive machine, but looking at your pic it looks as though there is more space below the wheel than I would expect - probably just a trick of perspective, but I can't see anything else that could be wrong.

If you look at 5:12 on the video the bearings do seem to be flush with the outside of the wheel.
Alex.

 

Ooookay. Solved.

A little bit embarrased I'll admit. I had accidentally put the bigger shim in between the bearings, not the precision one. So now it's flush and spins even when the nut is tightened. New thickness of the wheel 9mm, old 10 mm .

The kit is from your official store. Order #102129.

Thank you guys for "bearing" with me.

 

Thanks for letting us know what the problem was - useful for anyone else making the same mistake!

Hi Guys !

Recevied my Workbee 1510 kit this week and started the assembly and guess what ? I have a question !!!

When assembling the mini V wheels it is asked to insert a mini V precision shim in it. So far so good !!

When assembling the Y right plate it is asked to add 2 mini V precision shims on each screws. So far so good !! wait for it ... it's coming right up

When Assembling the Y Left plate it is asked to add 2 mini V precision shims on each screw. So far so .... wait what ?

If my count is correct that would make 12 mini V precision shims and only 8 are listed (and delivered) !

What did I do wrong ? or read wrong ? or understand wrong ? I french so it can only be one of these three !!

Many thanks to anyone willing to help a noob

take care and stay safe.

 

Hi Guys,

I'm a bit lost cause in the Sketchup model the miniwheels have no shim inserted :


But in the video at 1:28 it is said put in the precision shim ...

If I don't put the precision shim in the mini V wheels I have enough shims if I put them I don't have enough shims ...

I know truth is out there (SF fans will recognize ) but where is it exactly ?

Thanks guys for your help

 

Does anyone have any experience with tensioning of the y-axis belts (the long ones) on the 1510?

After I achive tension on both sides of the carriage, I move the gantry back and forth by hand, and after one or two runs, the belt is completely slack again...

Im starting to regret I went with the belt version, instead of the ones with leadscrew. .

 

I can't help much with the belt tension problem, but please be aware that if you move the axis around by hand with the motors connected to your stepper drivers you are turning the motors into generators and could damage your electronics.
On the belt tension problem - is the belt stretching or coming loose? Where did you get the machine from?
Alex.

 

Right now the motors aren't connected to the steppermotors.

I have adjusted the belt so that it almost vibrate when I push it down. Then I move the gantry back and fourth a couple of times to simultate how the machine would operate, the belts come loose. Or atleast the become really slack. It might be that the tensioner isn't able to hold the belt inplace. Maybe I need to modify the L-blacket.

Oh, and the machine is bought from OpenBuilds website.

 

I think I found what I did wrong. In the youtube-video it doesn't show that you should use a "zip-tie small" to secure the end of the belt to itself. But in the documentation it does.


Imgur

Also the official workbee video never mentions the ziptie, but I think I can spot it on one of the ends of the belt.

Sweet! I'll give this a try tomorrow. Will let you guys know how it went. Thanks!

 

Alright. I've ziptied the belts at both ends. Done on the x-belt, aswell on both y-belts. From my first tests, it seems to be working.

Images attached.

 

Hi guys !

thanks for your help earlier got it sorted, the reseller sent additional shims with the second package .

now I’m facing a very weird problem : the C-Beams for the Y-Axis do not fit in the gantry assemblies !! The pulley blocks the C-Beam.

like this :

Any hints what could be wrong ?

take care and stay safe.
Marco.

 

Hi It is a french reseller called PCCNC shop.

I finally found out that the axis of the NEMA engine is not centered and the assembly matters. Not sure if it is a caracteristic of the engine or the plate but anyways. It work now !!

Many htanks.

 

Hello,

I've been looking into using this WorkBee 1510 machine in a system I'm building and was hoping someone here might have some long term usage experience with the machine to answer some questions. I wouldn't be using this as an actual mill, but just as an X-Y gantry to hold tooling to follow along a process that's being run. This would be run at a fairly low speed along the Y axis mostly, but it would be in a production machine so expected 8+ hours a day running.

How often do the belts that drive the gantry need the tension adjusted to remain in tolerance or keep from going slack? How often do the belts need replacing due to wear and tear?

If anyone has enough hours on one of these machines to answer this it would be appreciated. I feel the 1010 model is better suited for my needs being driven by lead screws, but the extra travel on the 1510 could be useful.

 

My machine has lead screws on all axie. X has 1400mm long screws and Y has two 1500mm long. I got them off AliExpress.

That said, on my PhlatPrinter I had 6mm belts and I never had to tighten them in 8 years but to be honest I never really checked to slack since it ran fine all these years and never skipped a tooth.
