I have an OpenBuild 1510 belt-driven that I just assembled and tested after some initial electrical problems. My issue with the Z-axis is that there seems to be an inordinately small amount of travel between the bottom of the Z-axis and the work piece. For example, there is about 1/2" of the lead screw protruding from the bottom of the z-axis carriage that limits the movement of the router assembly. More importantly, at the z-axis highest point it trips the limit switch and there is barely enough room to put a bit into the router. That means that the router bit will not even clear the work when you proceed to the setup phase because the bottom of the z-axis carriage trips the limit switch again. Will switching the direction of movement solve that problem?
Just double check against the assembly videos/instructions. Shouldnt normally be the case, maybe just loosen stop collars and move it up a bit, or something is assembled wrong. Seconding Alex, some close up pics will help us tell you better Is the router mount and router's position inside the router mount at a suitable height: If it hangs too low in the mount it will not work great. Just moving the router up a bit may be needed, but yeah, Pics will help check that too
I used the latest build video to set and reset the height. The router collet is set even with the bottom plate of the z-axis. I will post some pictures of the issue.
The lead screw, if built correctly, doesnt extend past the bottom plate at all. At the 34 min mark of the build video, they tell you to make sure the lead screw is flush with the plate. Here's pics of my workbee Z Also, if you flip your spoilboard 80x20s 90 degrees to lay on the 80mm side, you'll gain more Z clearance.
Here are some photos of the z-axis gantry as requested. These photos are all taken when the z-axis is at its highest height and tripping the limit switch. The ones showing the router bit indicate how little room there is to insert the bit and when inserted you cannot raise the bit to clear the work-piece. The last one shows the protrusion of the lead screw through the base. It seems to me that all of this could be solved by replacing the outer attachment plates with something a bit higher to achieve the full travel potential of the z-axis C-channel.
Thanks for the pics. So, as mentioned before, you need to fix your Z axis lead screw. It should be flush with the bottom plate. I provided pictures of the top of my Z axis so you can see how far it sticks out the top. For your limit switch, you have two options. You can flip it around on the mounting plate, then re-mount it to the c-beam with the screw on the top (instead of the bottom like you have). Or you can move it to the other side, again with the mounting screw at the top. This will give you more clearance before the switch is triggered. I only have a blurry pic, but it should explain what I mean. And as mentioned before, flip the 80x20s under your spoilboard for even more clearance.
OK, thanks. I did not see the extra spacers at first view. I have flip my support rails as suggested and the limit switch. Did my first job - the eagle has landed!
Ah. I see you edited it 4 mins after I responded. We dont get notifications on edits so no way of knowing unless you tell us. Glad you are sorted.
