You could extend the back frame/compartment a bit and throw your electronics/filament etc. in there as well. Very nice clean design!

 

This is a really nice design. You can probably make the Z axis less likely to skip by putting an idler between the threaded rods. See picture below with and without the table.

Ok Keith, let's build this thing. I have been searching for a design for my first build and this one has everything i want. I have a CTC 3d and I'm looking to move up.

 

I'm new here. Is it ok if I grab your initial work and post it as the beginning of my build? Of course, giving you credit.

 

Keith, Good luck on your new venture. Hope it doesn't take you away from us for too long!

 

Neat design. I liked it from the very first day I seen it.

I did implement your design in Fusion 360. Designed some custom plates for connections and steppers etc.

You can have a look from here. Hope you like it and maybe it gives you few ideas (Please note I have never designed nor used a 3D printer till now)

I might build this one when I have enough funds for it.

Glad you like some of the ideas Keith!

Yes front panel needs a few more touches (surely a door) and rear plus bottom covers with a set of neat feet as well maybe.

Has anyone yet had a closer look at these designs or tested them? They look really interesting. I'm going to build a Diode laser and this design looks quite smart for that. I thought about building a CoreXY design but this may be a good alternative although it's quite a bit more complex and costly due to the amount of idlers - but definitely a nice approach.

 

Thanks, Keith. I know Richard of course - quite for a long time even.

Thanks for your explanation. I'm not worried about CoreXY performance or board temperature. I've already done different 3d printers with CoreXY and they always ran smooth and pleasantly. I think i'd prefer CoreXY over this design because it's just a bit simpler mechanically.

I've just loaded the F3D files from @GinoTheCop into Fusion360 today - awesome work man. I wish I'd have the time to plan my laser project as detailled as you did it. Would love to publish it later but I guess du to time constraints I'll have to do it quite more basic in planning.

 

Thanks @Helmi

I guess no matter how detailed the initial plan, at some point something will always not be right when building it. So as long as you are ok with basics you can always go around design problems. Thats the process of product development and it is impossible to get it all right at first run.

Good luck with your project.

 

I like this build and its similar to my TitanXY config. that I have built.
CoreXY seems simpler

 

Like this design. How does moving this much mass in the z axis compare to conventional moving bed?

 

Thanks, Never built yet so not sure myself If you're xy remained at top and z build moved up, what might the weight difference be between a build platform with just z and your original xy frame complete?

 

Hi @Keith,

Nice job, in fact we did a similar design like you do for our commercial printer but instead of using the core-xy gantry, We are using UM like gantry and you're right, this design have a fix weight rather than using moving bed on Z- axis but a little bit expensive when we build it. Good luck for your design and nice design.

 

Guys!! Is this really going to happen? I have ALWAYS wanted (well since 2013 to be precise) a static build plate on a CoreXY moving Z, and this is it!!!

 

Thank you, I like more the aesthetics of your design, so, if you could share your files with me I will greatly appreciate it
