Hi again.

I have measured everything again in more detail(for all motors, all dimensions).

Space is definitely an issue. I will have to elongate the z cart about 4-5mm both on the top and the bottom, but that should be quite easy.

There is another question though. I’m trying to match the dwg pieces to the 3d model ones.

The piece called “Z cart front” on the DIYLILCNCv2 Panel Inventory(and which is in the DIYLILCNCv2_2D_4.dwg file), doesn’t look a lot like what’s on the 3d model. Sepcifically, is this the same piece: http://postimage.org/image/nrims9nuv/ ?

There are no holes for the mounting of the motor or the bore on the dwg and the red line indicating the motor position is missing too.

Is it an error on the dwg or am I missing something..?

Hi Taylor and thanks for your time.

I plan to use the cnc of a local university to do the cutting.

One thing I just noticed is that the length(or “depth” if you wish) of the motors you have used in the 3d model is 55.5mm, while my motors will be 100mm(almost double). (specs: http://cnc4you.co.uk/resources/60BYGH401-03.pdf ). Sorry to be a pain, but could I have your opinion on whether they would fit and wouldn’t get in the way of anything, if you have the time to check it out?

Regarding the Z-axis motor:

On the vertical dimension the motor in your design is in contact with the top piece, so no space there, but there appears to be about 7mm clearance(before we hit the aluminium angle on the bottom of it, while my motor will only be 4mm bigger. So should be ok, by only moving the 4 mounting holes a bit down.

On the horizontal dimension, the clearance between the screws that mount the top piece to the front one(the one where the motor screws on -as shown in this image http://postimage.org/image/3v44jp5t1/) is 65mm(again, the faceplate of my motors is 60mm). Do you see anything else that might be in the way..?

Sorry to be a pain and I hope my description makes sense, but I will probably only have one go with this cnc and I hope to get everything right the first time.

Thanks.

Hi again,

after a couple of months of distractions I finally have the time to finish it.

On the 5th post of this thread, Taylor pointed out that one of my stepper motors might not fit.

Do you mean this one: http://postimage.org/image/5t7cgcuol/

?

I can see that the height may be a problem as the distance indicated with a red line on this image( http://postimage.org/image/trcfvdt91/ ) is 58.59mm. That is 1.5mm short of what I need to fit my motor(60mm).

There appears to be a few millimeters leeway though, before the aluminium angle bar, so I was wondering if maybe the size of the piece does not need to be altered afterall.

The distance between the screw holes looks ok.

What do you think? Am I right?

Thanks in advance.

Thank you Taylor.

There is no reason to thank me for my patience. You do this in your spare time and you provide a free good. You don’t have to meet any deadlines. Just a line to say you’re working on it though would be great, as this forum has been rather quiet and I was worried the project could have been abandoned.

I’ll check out the files and post again if I have any more questions.

Thank you once again.

Sorry to bother you again, but when you get the chance, do upload the Rhino v4 3d model file please.

I even tried buying iRhino for iPhone(that stated it can read v5 files) and that didn’t work.

I tried Okino’s Nugraf that is supposed to be able to handle v5 files too, with no luck.

[keraynopoylosParticipant]

Thanks a lot!

If you could just say so here when you do so, so than I know.

(btw I don’t have a Mac)

[keraynopoylosParticipant]

Sorry to be a pain.

Could you possibly save the .3dm as an older version, as I get a “The file was created by a newer version” error message and can’t view it even when I tried a 3dm viewer.

Thanks.

If you’re using the HobbyCNC Pro board, then you’ll be running the motors in Unipolar connection, so your current will be 2.8A.

And without being sure, I believe that’s peak current.

[keraynopoylosParticipant]

Please excuse the offtopic nature of the question, but it has to do with my project.

(tried google searching and wikipedia researching to no avail)

I have this PSU:

http://cnc4you.co.uk/resources/PSU.pdf

So I know the Output(DC) Volts, Amps(max) and Watts(max).

What I’m trying to calculate, is the max current(amps) of the INPUT (AC).

I want to know that so I can properly fuse my mains power cord and also buy a power switch and Estop switch of the appropriate specs.

I would be grateful if the method is briefly explained too, as I’ll have to recalculate(after adding router and possibly vacuum current ).

[keraynopoylosParticipant]

Thanks for the reply..!

Regarding your point 2, the hobbycnc pro can handle it fine, as they are rated to 2.8A current while the board handles up to 3.

[keraynopoylosParticipant]

Hello and thanks for the reply. I have already ordered the HobbyCNC pro board.

Regarding the beta, while I would be more than happy to assist in this way, I’m not sure I’m the right candidate.

I will probably take my time sourcing the parts/materials needed(I hope to find everything else in europe) and building it, as I will be doing it on my spare time(which is not a lot). I guess you would like to have the beta phase move as fast as possible.

[keraynopoylosParticipant]

Hello and congratulations for your work on the project.

I have been following your website for a while and have been waiting for Ver.2 in order to get the parts and start building.

If I have understood correctly, the HobbyCNC PRO Chopper Driver Board Kit is what we’ll be needing for the electronics, right?

Does anyone have any idea if this can be bought anywhere else other than http://www.hobbycnc.com?

I am particularly interested in any vendors based in Europe, in order to save on shipping costs and not have to deal with customs and importing fees.

(also, any updates on when we should be expecting the design files?)

Thank you in advance and well done once again!
