My first CoreXY!

Great models, looks like it will be great machine. Ian's advice seems very sensible.
One question, since I have several enclosed machines, and your's seems to be enclosed, how do you intend to enclose the top?
According the OP it's built and running - shame we don't have any real pictures. I'd like to know about the thing that has an LCD which looks like it might be a PanelDue but with some other switches and a knob. It looks like it's inside the enclosure?

Hello handicraft friends!
First of all, thank you for your praise of my work.
I designed the printer with Autodesk Inventor because I also work with it professionally.
As the name of this thread already says, it is my first 3D printer that I developed and built. Thanks to all of you who post their impressions and suggestions for improvement and thus help me with the further development.
With regard to the building platform and the Z-axis, I would like to say that the threaded spindle is not clamped at the top, but only guided. Below at the engine is the fixed bearing, at the top is the floating bearing.
The four guide shafts are adjustable by the brackets, which have a little play before tightening the screws. During assembly, the building platform is at the bottom first, then tighten the bolts of the shaft mount, then move the building platform upwards (without threaded spindle) and then tighten the upper screws. Only then are the threaded spindles and nuts assembled and screwed on in the same way.
This really works very well. The mounting of the heating platform with only three screws is possible and a good choice. But I thought that four screws are a bit more stable and not statically overdetermined by the springs.The panelling with plexiglass has been ordered but not yet delivered. The upper end of the printer is not yet clear, but I have some good ideas.
I didn't build the display in the 3D views. The DuetWifi can be used without a display.
If you have any further questions or suggestions, please do not hesitate to contact me.BerTiNax
(Sorry for this English, it was translated with DeepL)PS:
Actually, I'm looking for someone who can view and check my configuration files (. g).
-
Super nice, really good job on both design and fabrication.
-
Yes, that looks really good and I'd say from that print that there can't be much wrong with your configuration files. Post them anyway and we'll take a look.

Ian, what would be an optimal design? I'm making a similar machine and the z-axis is the same as this one.
Haven't cutted the aluminum parts yet, so there is time for me to change it.Delta guy here… a moving bed is unknown territory
The OP has a great design. I use the same concept with mine, so does Stratasys with the Fortus series. This printer looks well designed and quite tidy.
-
Your printer looks really professional! Great job.

Fair comment but I've been helping a couple of guys from a company that I met while at the TCT show. They had problems with the Z axis binding because they couldn't get all 4 vertical rods perfectly aligned. So IMO it's not the best design concept.
-
I see that you have your belts in the same plane; I use the same config. Could you make a closer picture of the part where they cross?
Thanks.

Hello handicraft friends!
This is a small bridge that prevents the two belts from touching and rubbing against each other. It is a very simple and effective solution. (If you want, I can send you the. stl file.)
-
I have as similar system, with a PTFE sheet between belts. I just wanted to compare, as yours is smaller.
Thanks for the picture!

Sounds like a problem with design rather than concept. If alignment difficulty is the problem I think we could agree getting two actuators parallel should be easier than three.
