Hi, your design seem awesome, and under-liked !
I'll try to make one this year, probably before summer. But I have a question: How to you 'fold' it, or disasemble, for storage ? Does belts are easy to remove / install ?

Nice design,
I am making something similar, and considering using a similar Z axis.

One question tho, how does it fare with forces along the y-axis?

The way the z-axis is designed it looks like it cannot handle too much force before the plastic plate holding the drill would flex around the bottom part holding the plate/dremmel to the pipes.

I really like this design tho, very sleek looking. :)

Hi thank you for sharing this,
I have extra m8 screws and 608zz bearings. For this project i want to use them.
Can you redesign only bearings and bearings screw socket ? If you can ?

Thank you :)

I also ask for 608zz bearings design

Hi, did you made the design for 608zz?

Hi. Please feel free to download project from my google drive and redesign what you want :)

Hi thank you for sharing this
Thank you I have started your health care press ABs ( Printing will last approximately 1 week )

Can I add 4 nuts and pipe holder clamp to secure the (support.stl) part ? To fix the table

I am using freecad

I did not do it because there are no measures

Can you help thanks

( You are clamped with pliers while testing) :)
The weakest point of CNC machine (support.stl)

Thank you

I have sent you private message :)

Hi.

I am in the process of printing your design. Many thanks!

I would also like to see this modification. If you have designed a new pipe holder, can you upload it?

cheers

Andrew

Hi, thx for sharing this.
Can you tell me what infill you used printing the objects?

Hi,
You should setup as much as you can, because it should be very stiff.
I have used 50% line type infill.

Yeah, figured 50% should be the best deal.
But it requires a lot of patience ;-)

What setup for the electronics did you use?
Arduino? And would you have any links for what you used as source?

Interesting design. What type of plastic did you use: ABS or PLA?

I have used PLA.

Классно сделано! А можно "300мм с резьбой М6 стержень" заменить на "THSL-300-8D"?

This is a great design! Was wondering if you would be willing to share source files so this could be edited to accommodate 23.5mm conduit?

Hi,
I have checked my pipes and they are fi25.3mm :D
I have bought them described as fi25mm.

Since there is backlash cancellation on each axis you can easly use both 25mm or 25.3mm pipes

I'm confused with the measurements on the pipe. I get the radius and thickness, but the random 0's and the amount in the list being more than 5m of pipe is confusing. For clarification, can the comas that are intended to separate the ones and tinths positions be changed to decimals (points, periods, full stops, etc) so that people don't end up with 3x5m sections and actually end up with 3x0.5 sections?

The comma as a decimal separator is standard throughout much of Europe. Those aren't random 0's, and the total of the pipe lengths is just short of 5m.

From the plans:
5m pipe 25mmx1mm (4x1m, 2x0,3m and 2x0,19m)

0,3m is 30cm. 0,19m is 19cm.

4x1m + 2x30cm + 2x19cm = 4m 98cm.

Quite cool.

FWIW it would be stiffer if the side rail structure were the full width of the bearing. That's actually true with both the X & Y bearing mounts. Moving the material will give a stiffer structure.

Do you know how to modify the print to form matchplate patterns for sand casting in aluminum alloy? Using steel cores you don't have to machine them true. Given the difference in properties between metal and plastic, using 3D printing to make patterns seems very attractive.

Not having a 3D printer, I am planning to build something similar using a stone surface plate as the base and standard hardware. The opposite of portable, but different objective.

Does sizing work with 1inch tube?

There is no problem with trolleys. Maybe some with parts where pipes are mounted directly.
I have measured my very cheep pipes and they have about 25,3mm so it should be ok.

Would be awesome to see some pictures of the assembly/disassembly process

I think that those pictures I have added are enough :) Everything fits without any special thinking about it :)

looks very interesting. but shouldn't there be 2 rails on every axis? just to stabilize it...

Hi, There are 2 rails on every axis:) You think probably about 2 rails both sides of Y axis. Most issues with stability comes from bending 3d printed parts not from rails exactly and 2 rails per axis on this lenght is quite stable.

Very Cool Idea. Like your design
