G'Day Keith,
Finally got to you . I just viewed your new design. Could you answer 2 questions please.
1. Ship to Australia lknow it's expensive. However to purchase parts here is very difficult as suppliers do not have to variety of parts you are fortunate to have. I do not have the time or patience to chase pasts.
Shipping I will leave it up to you to pick shipping.
2. Will sainsmart handle 5 nema 17 's. To incorporate a dual extruder.
Cheers

Nice sleek build @Keith Davis . I look forward to seeing the source filers for it.

Wow,very thorough. Quick question, do you live in the GTA? Myself, I am in Niagara Falls, Ontario.

 

Looking forward to it!

Now back to waiting for parts <sigh>. I ordered some bearings last winter for the OneZ and when I went to plonk them in the other day, it turns out the outside diameter was larger than what I had ordered.... Next time I'm checking stuff when it arrives instead of just tossing it in the project box!

 

It's a gift....

Hi, I see you are selling this. I would buy one but you don't ship to Canada. Bummer

 

I have a U.S. drop ship address in Niagara Falls, NY, for my business. I then broker the goods across the border myself. If anyone in Canada needs to, I can receive the package for them and then re-mail it once it is in Niagara Falls, Canada. It costs me $6.00 USD to receive the package, so I would charge $10.00 USD to forward the package for someone, plus the cost of the Canadian postage.

 

Keith, perhaps it's just *me* (and why wouldn't it be, considering how long it's taking me to get the OneZ together...<sigh>) but the pdf bom is not displaying for me like the one on the OneZ.

The parts are on one page, links on the next page and there are 4 pages in total. I'll upload a screenshot for you. It may as I said be me, as I use Linux and non-adobe pdf readers, but I wonder, seeing the OneZ bom displays normally.

If' it's just me, no worries... I'll figure it out what goes where.


And Anthony, that is a very kind offer for fellow Canadians. I'm lucky that I only live an hour from the border and there are 2 commercial outfits that can take care of bringing it up to Winnipeg for a fee. A lot of small packages gets expensive though...

 

Looks good now, tnx.

 

Keith,

It depends on where the package is going, and who the shipping company is. Some companies like to pad their profits with ludicrous "brokerage" charges. It's the reason why Canadians don't want to order from the US unless it's shipped via USPS which does not have a brokerage fee, but rather just the taxes (and only if Canada Customs decides to collect, and often they do not) and there's a fixed charge to cover the expenses that Canada Post incurs when collecting and managing the money on behalf of the CBSA (Canada Border and Services Agency).

Back when I was an avid photographer, I would order camera lenses from New York as the price was 1/3 of what was being charged in Canada at the time. The company I dealt with in NY would only ship via one company who offered econo shipping and overnight shipping to Canada. While the econo ground shipping was much much cheaper, the brokerage charge equaled exactly the same as the companies Next Day Air service (where the brokerage is covered in the Next Day Shipping price). It cost *me* the same to have it shipped next day air as it did with econo ground service, so I always specified Next Day Air... at least I got something for my money!

However, more often, a business in the US does not ship USPS (many use companies like FedEx, UPS or DHL instead) and will ship to any lower 48 at no charge... So, sometimes it pays to have a drop point on the US side of the border and then either pick it up there, or have some service pick it up and bring it across the border. I have had several quotes over the past few years of $0 shipping to ND (about a 1 hr drive from here), but $80+ to my address in Canada. It's cheaper for me to drive to the US, pick up the item and bring it across the border myself.

The problem is the shipping companies, not the buyer/seller..... It may very well be cheaper for you to ship to a US address at $40 and the customer dealing with the rest, than having you ship directly to a Canadian address.

I used to see these problems all the time when I worked as a letter carrier. People would buy something from Amazon in the US with cheap shipping to Canada, but the brokerage costs would make a $15 item cost $35 or more + our taxes on top.....

 

Just to answer your question:

My printer is going to have an auto-level system because I am going to print on different (swappable) build surfaces that might differ in height. So it's less of an "auto-level", but more of a "height detection" system.

 

Do you use no microstepping on Z? I currently use 32x on duet WiFi electronics. I did for a time use no microstepping on ramps 1.4 and the noise was horrible. My concern though is that I use the Z offset feature of S3D for first layer, and that needs microstepping. Might have to do some tests.

I have a very similar set up to you actually, and have arrived at all the same conclusions. I use two acme screws, driven by a closed loop belt and high torque nema 17. I have not centrally mounted my X axis motor, but I did switch to anti backlash nuts to sort out the unbalanced axis. When I used brass nuts (the common ebay type) the backlash was horrible. Most people assume that the weight of the axis will stop the backlash, but actually it makes it into a see-saw, with the pivot point on the heaviest side of the axis.

I also use 6mm tooling plate. The typical pcb board heaters (mk3, also common ebay crap) warp so much under heat, and I'm almost certain this moved the bed on every heating cycle.

I have to say though, your build beats me on compactness and minimalism. Mine is a tank.

 

I have to agree with Keith, micro stepping is not a solution, but rather a poor solution looking for a problem to solve. Auto level is also not a proper solution to non level build plates. It is far better to get the level straight and keep it there... If a different Z hight is needed for a print, add it to the g code.

 

On the DIY guide, the first picture is broken. I'm sure I could figure it out anyway, but just wanted to give a heads up.

 

To help narrow it down, this specific image does not display:

I think this is supposed to get the correct link to the image. http://3dwrx.com/TrueUp/DIY/1.png

 

Also, the BOM for Frame Assembly shows 2 M5x8mm screws but the PDF BOM does not show any at all.

 

It's called math. You can simulate a crooked Y axis by just moving X and Y accordingly?
