Hi all, I am in the process of building my Ooznest Z1+ machine. I'm on the step where I am attaching switch 2 to x plate front. It says to use m2.5 ×10mm screws into the threaded holes in the plate. However, the holes are too big for the bolt? They just drop in rather than screw in. An m3 size bolt would fit into this better I think this is a production error. Can someone clarify? Thanks in advance.
Are you following the right set of instructions (for the Z1+)? 2. Limit Switches They say to use 3 mm plastite screws. Alex.
Thanks for the reply. I am following these instructions... Original WorkBee Z1+ Assembly Manual - V1.0 My model version number is Z1+ V1.0. Am I following the right instructions? Thank you.
You are correct, those instructions are wrong (although I had to carefully enlarge the holes in the limit switch housing to get a 3 mm screw through), but the location of that switch is also a poor design. It results in the wire to the switch being threaded through a hole in the X plate and then being too close to the X drag chain. Chafing, catching on the drag chain and wire breaking is one of the commonest failures on the Ooznest workbee. Because the switches are wired as normally closed (and are only used as homing switches) any break in the wiring is read as the switch is triggered when you try to home the machine. I would recommend siting that switch somewhere else - it's incredibly difficult to get at in that location anyway. If you are on Facebook join the Workbee CNC Users Group and search for "Z limit switch" for suggestions on how to mount it on the side of the X gantry plate and use a simple bracket to trigger it when the Z axis is at the top of it's travel. I include a link to earlier instructions that should work if you really want to leave it in the location at the bottom of the X plate. 4. Limit Switch Assembly & Mounting Alex.
Yes I have. It being the weekend I thought I'd ask on here whilst waiting for them to respond. Thank you.
I have had a reply from the team at Ooznest who assure me that the plate is fabricated incorrectly. There are sending out a new x plate front.
