When the new model will be ready.Your information.I am curious about the new model.

The new model has been put to the side for the moment, busy at the moment.

Comments deleted.

Any updates to this yet? Nice job. Looking to develop something similar.

Ye quite a lot of parts are getting updated or removed to simplify the machine. Waiting to rebuild it and test new parts before uploading changes. Won't be for awhile with college and all.

In the BOM, you're still using the 6-belt 360, it is probably a mistake? 2 pcs 360 (to motor) and 4 pcs 860 (X&Y), perhaps?

Your absolutely right, I'll make the readjustments to the bom.

Your absolutely right, I'll make the readjustments to the bom.

I see that you developed all this construction in Solidworks. If is it possible to put the source files of some details? I like the design and I would like to make, but I will change some things to make it easier and easier to manufacture, and want to leave a minimum of 3D printed parts, because I think they are not very reliable.

Hey alec220. Your right it is developed in Solidworks. I will make a link to the source files in a few days. It makes sense, like you said about the 3D Printer parts that they are not very reliable in comparison to metal parts. I think the next printer i will have will no printed parts at all. Thanks.

Pretty nice looking. One question however. If you are going through the trouble to redesign something to improve on it, why would you bother using standard acme lead screws and nuts for the Z? Why wouldnt you go ahead and use ball screws? They arent that expensive anymore for decent ones.

Ballscrew doesn't really offer any advantage when it comes to the task of moving the z in the case of this printer since backlash isn't a problem since the mass of gantry keeps the leadscrew nut down and it moves relatively slowly. The leadscrews used are relatively high quality. I have been getting 50 micron layer height no problem. High quality ballscrew can cost significantly more then high quality leadscrews. Google the: the engineers guide leadscrews vs ballscrews .The first link will have a PDF explaining the pros and cons.

Your answer is sport on. That's how an engineer should be.

Thanks vertexEnd!
