You need to connect your external driver to the expansion connector, not to those test pads. See https://duet3d.com/wiki/Using_external_drivers.

You're Welcome.

Thank you, FlowerBob and DC42. This thread helped me get my printer zeroing and bed probing after digging through the wiki I don't know how many times, only to end up off in the weeds trying to figure out what I was doing wrong.

Now, if I can only figure out how to prevent my bed sagging so far due to the overly thin material provided by the kit maker…

Just found that an old bead-type Thermocoupler works fine.

Unfortunately ALL the thermocouplers in m3 cartridges (fitting for newest E3D and UM2+) is doing the 2000c act. Yes, also if the thermocoupler board and thermocoupler is the only thing attached.

Thank you, sir!

Either one of the above recommendations should work but as an add on, if you truly want to get rid of the crappy ISP router there is a way to do it

Plug that spare routers internet port to one of the available ports on the ISP router and configure it to be a firewall/router.

Next configure the ISP modem/router for passthrough bridging… On Frontier routers its under advanced and connection inside one of the dropdown menus... this will disable the router features of the modem and allow your personal router to be the primary router without creating double nat network issues.

Then on your personal router you can assign an IP from the DHCP lease configuration page.

You will bo longer plug devices into the isp router but instead plug them into your personal router, as well as only connect to the personal routers wifi

They are optical endstops and they are lit when on, but not triggered as well. They weren't lighting and I repaired the solder joints and that got them working, one of them has gone back out, I have a spare and a few spares on order as back up.

Really should start adding questions from the forum to the troubleshooting section, there isn't much there.

@gzcwnk:

Ah cool….exactly what I wanted, so an airstream down the middle? say a 5015 centrifugal fan?

That should be more than adequate.

my motor wiring was incorrect; the pairs go in order (AABB). The LED verification of coil pairs was helpful to remedy this. hope this helps someone later on.

I am having the same problem, Could you please tell me how to correct it.
Thank you

Yeah i read that on the wikipedia, it just had me scratching my head because as you can see in the photo the psu states it has 5vsb

I cracked the PSU open last night and 5vsb doesnt exist on the PCB everything is clearly labeled even the non used like -12v

That fixed it, thank you very much for the suggestion of where to look dc42!

You probably have a bad crimp connection at one end of the transmit or receive data conductor in the cable. The 4-way power and signal cable can be very long but the resistance per conductor should be kept to 0.1 ohms or less. The one on my delta is nearly 2m long.

The ribbon cable used to connect the SD card socket is limited to about 0.4m.

Great Support thankyou

Actually I take some of that back! It still seems like it is taking extremely course steps, so much so that the table and build plate are vibrating. If you look close the build plate you can see it. The belts and fasteners are tight yet it is cogging badly at slow speeds. Is there a way to access the stepper drivers directly to tune them? I will try to post a video in a bit.

You can see when it starts to resonate.

Her are a couple videos;

I'm not sure if I'm replying to an old post, but there are some great resources on the FSR sensor and the Duet, here are some links that should help:

Thanks for your fast reply kelchm!

Yes there are another 4 CS lines on the expansion bus, allowing a total of 4 daughter boards to be used.

Thanks for your reply
i got it from https://www.duet3d.com/

I liked these so much I got 12. If you have to have them all in one, the shafts just press out and then you can turn down your leadscrew to size and press back together. http://www.ebay.com/itm/111122742913?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

And they are not made out of CHINESIUM
