Here is the way to go!! My next upgrade!! Take a look at the specs: Redirecting...
Mine too. All I need now is money
Its tempting, got the money, but I donāt do much anymore with the xcarve. I think Im gonna wait a while until I see more people buying this kit and see what they think about it, then I might buy it. I wish I had more room to go bigger tho.
First things first: impressive, I really really like that build. Iām amazed by it and this thread has been shared to a lot of my friends with just the comment āI need to do this.ā
Second:
Iām planning on getting rid of the V-Wheels this year, Iām just asking myself āhow?ā. I guess some of my answers have been answered here
You mounted your linear bearing on top and bottom of your rails. Is there a specific reason for that?
I was wondering, if I could take a c-beam and mount two bearings to the side with the 2 extrusions of it, then the plate, then the rod (everything facing the āoutsideā of the machine, I hope I made myself clear).
Since you clearly know that stuff much better than me, Iām curious why you chose this design.
PS:
Happy easter!
Thank you @DominikMai! And happy Easter to you, too!
I guess it depends on if youāre talking specifically about the X or Y axis. I did them the way I did on the X axis so the original X carriage could be reused. And although I did replace the Y axis makerslides with 20 x 40 extrusion, it was designed from a true āupgradeā perspective so that someone would not even have to replace their Y makerslide. The X axis extrusion would need to be replaced either way because the original wide makerslide doesnāt have the necessary slots to work with. Thereās no reason you couldnāt do what youāre talking about, but keep the component āstackā as tight as possible.
Additionally, this particular design was developed to support an incremental upgrade path where a user who purchased a Supergrade screw-drive upgrade from @LukeWilson could later upgrade to linear rail bearings while using the existing side & end plates.
Thanks for your feedback, I didnāt consider that aspect at all to be honest. Thatās because at least here in Germany linear bearings and the direct drive are that costly, that the rails donāt matter to be honest.
Iām currently planning with some c-beam rails and right now am at the point im asking myself whether I should have 2 bearings per rail, or if one would be sufficient enough.
It really depends on the height of your X extrusion since this ties the 2 Y axis rails together and basically sets the squareness. For example, an 80mm tall X rail will hold the side plates more rigidly and squarely than a 40mm tall X rail (hope this makes sense). The 80mm tall X rail affords a 2:1 advantage over the 40mm rail for holding the side plates square (assuming the ends are cut good & square). You could probably get away with a single rail on the Y axis, but I opted to go double to help keep the assembly good & square. A rough ASCII example of your sideplates: | | vs. / / or \ \
Either way, your machine accuracy will be measurably better than compared to V-wheel guides. If youāre only planning on cutting softer materials then 1 per side should serve you well. If you want to cut metal or other hard materials, you may want to consider going with 2 per side.
Thanks, I really appreciate your input. I think I will be doing 2 per side, for all the reasons you stated. I just need to find a good vendor shipping to Germany I guess. If I can match the professionality of your machine to 80% Iām happy
Any more kits in the works?
Right on queue.
