I’ve just finished the build checked limit switches working ok, homed machine ok, tried moving to extents and x and z ok but a nasty crunching noise from the y drag chain, or more specifically, the now broken Y-Drag-Chain-Moving-End-Mount .I measured the length of my y drag chain and its only around 85 cm long. on the face of it, the chain seems to be around 15 cm too short

I’ve been watching the tutorial video - How to set up a job on a CNC machine

https://youtu.be/qQPUg0IgrrE

When ‘homing’ the machine (by hitting the HOME XYZ button) my Machine position does not read -3 -3 -3 as Ryan suggests (it reads 300.0, 270.0, 94.00). All screen grabs I’ve seen show these as 0,0,0 - Is there an issue? Thanks

I've read the guide and watched the video for adding an emergency stop button.

Am I correct in thinking that “the router AND it's power" have nothing to do will the supplied machine, duet board and power supply?? In other words, the router cable goes “up in the air to a hook" then back down to a 13amp mains plug socket??

Placing an emergency stop button in that scenario is easy - break the live feed, wire in stop button - job done.

Your guides “stop the actual machine and stop the program being sent" - however, the router would still be running ………, which would be dangerous.

How can I wire an emergency stop button that “does ALL three" i.e stops the router, stops the machine, stops the programs??

If this is possible, is it then possible to have, 2, 3 or 4 stop buttons - one on each side, one at the front, one on a breakout “control console" located 3 feet to the right of the machine? (I'm planning of trying to get the Duet/Power Supply/Mini PC remotely located in a large flight case, so that the “brains" can be taken home each night and not left in my workshop).

Thanks - Kev :-)

Will it be possible to engrave a name in the middle of one of these pieces of wood? To clarify there will be:

about to order Workbee. I have good WiFi in my man cave but can’t decide between WiFi or Ethernet.

Any major advantages using either one?

I’m getting non-repeatable z-axis homing. If I set the work z height, then home, then return to work position it is often substantially different. I’ve used a clock gauge to check and it sometimes over 0.5mm difference!

The z switch is tight and making contact, though the lever looks a bit flimsy for the task. I’ve also checked the z couplings.

Any help would be great.

Thanks

Rich.

I’m at the stage I’m trying to attach the router, but I think I’m either missing a part or I have something installed wrong.

In the box with the Router came the dust guard, but the 65mm 3D printed collar doesn’t fix inside the guard and I’m a little confused on how the collar would be clamped to the mount as there isn’t a way to attach it via the four screws. Do need to disregard the collar and just clamp the router via the M8-Cap-Head-25mm Bolt on the mount?

Thanks for the reply

Please can you let me know how can I set the machine in such way that it stops in the exact point where it actually finishes the job? In other words I do not want the machine to go to workzero after completing the job.

Appreciate if you advice.

I checked with the person who manages our network (ethernet) and they confirmed that when connected to a known good ethernet cable and port the board was responding to ping commands. But when scanned it showed a weird response on the web-server port, in their words the scanning software reported the web server as active but it wasn’t sure about it.

Then I took a stupid step. Lacking non-network methods for updating firmware I went to the Duet site and followed their instructions for installing firmware over USB. This involved formatting the SD card, and idiotically I did not make a backup. After the wipe, copying their card image, and configuring the correct IP address over USB, I was still not able to connect over the network.

At this point, I’m requesting a known good SD card image to burn and verify that this is not a software issue before I move on to exploring hardware related failures.

When I first tested the y axis movement the whole gantry went out of square and there were a lot of mechanical ‘complaints’ from things binding and griding.

I did a quick read and discovered that I hadn’t tensioned things with the little hand wheel.

This was done and the gantry now moves straight without the binding and grinding, but I’ve got some nasty sqeaking noises that come and go as the lead screws turn.

The noise seems to be from the Y plates - I’m guessing something to do with the ACME nut blocks. The wheels seemed fine during the initial mechanical build.

I’m presuming that this is a common set up issue and I’d like to avoid disassembling too much in a random attempt to fix it!

Any help appreciated!

Are these compatible with the work bee or are there others recommended?
