New Workbee Z Axis

New Workbee Z Axis

Hopefully an upgrade of the Z axis of the Workbee.

    The bottom plate is the workbee plate. The top plate is an extended workbee plate. This *might* end up attached to rails in which case the bottom plate will likely be replaced with a machined angle bracket. The top plate would be the same. Not seeing any reason to get rid of the wheels on the x axis at this point, tho. Would rather not add that much weight to the X axis. 175 wheels are lighter than HGR20.

    Some mistakes have been made. A divot on the bottom side of the top plate where the broken tap extraction went south. I'm not using that lead screw block. Since I cut the top at 6.35 instead of the 10 I designed it as I didn't countersink the screws so I had to print the mount with some domes to allow space for the screws.

    The mgn12 blocks need to be lubed but I'm not entirely certain how to do that.

    Might flip the stepper and hang it behind just to consolidate the mass towards a point.

    If I can figure out how to get the zaxis off the workbee without removing the x axis I might give this a test run. This version mounts to the existing plate via the openbuilds cbeam plate attached to the back.

    I just bought a syringe and thick gauge (not too thick) needles, just press some superlube in there

    To remove the Z axis (unless it's a very recent workbee from Ooznest) you will have to dismantle the X axis gantry plates - remove all the wheels from the X axis. You shouldn't have to remove the X axis C-beam as far as I recall (got linear rails now so can't go and have a look).

    This seems a plan. Looking at the document Ehask71 linked I have to assume I want grease in the bearings but I think an 18ga needles should still be able to push this.

    Oh, yeah, I can just remove the lower wheels to get access. Might try machining an special hex key that can slip behind the plate.

    Still working on how I want to go linear rail for this. I have a bunch of HGR 20 which should be great for the y-axis but seems awfully heavy for the x-axis.

    Also, MGN12 isn't great with v-slot. A little too narrow. 15 (mgn and hgr) would be better all around.

    Yeah 15 or 20 for sure! I am planning on doing a linear bearing upgrade on my Lead1515 whenever I finally get home to build it ... I planned on 20 for x & y and 15 for the Z

    @DarkPenguin, lower wheels, yes, but you'll also have to detach the nut blocks from the X gantry plates or remove the leadscrew. If I recall correctly the Z plate is attached to the X plate from the inside - Ooznest have changed that design recently so you can unscrew the Z plate from the outside.

    I have to remove everything to use some new plates so I think I'm just going to suck it up.

    Current plan is to use some of my hgr 20 because, well, I bought it. Still trying to sort out how I'm filling the back of this. I'm thinking a handfull of spacers on the back side and 3d print the rest. Cable track will mount to the 3d printed filler piece.

    No way in hell am I buying that many black corner brackets. They are more expensive than gold.

    I think this is the extent of what I can do without buying more aluminum.

    I have a workbee 1010 and I bought High Z Mod for Lead 1010 CNC , not realizing that they were different machines. Where can I find out what parts I need to connect the upper selection like the lower section from the attached pic I have not been able to do anything on this machine. I contacted customer support and they treated me like the idiot I was for not realizing that the two 1010 builds were different. and that I should contact the forums. Any help would be awesome. I know what I want to do I just don't know what I need to buy.
