The wifi firmware version is given in the Network section of the M122 report, unless the WiFi is still in the Disabled state.

The G-Code console tab should provide you with a history of messages.

Thanks.. !! I'll look into that. I'm still in the design phase of everything so i'll look and see if there may be a another way of doing multi-material instead of directly form the duet. I know in interviews Prusa mentioned that they are using a arduino for the material handler so maybe I can do the same and use one of the data parts. I wanted to map each material in the changer as a tool and use the Tx command to switch between materials. this may still be possible as i haven't gotten all the way through the documentation. 🙂

increase the H param on your M558 line (Temporarily) to say H30 and try again sounds like you have your Homed hight set a little high in your M665 line and that is what is causing the initial head crash.

@resam, please check that the thermistor connections are well-insulated from the hot end metalwork. Shorts between the leads of that type of thermistor and the heater block are common.

In my machine, the Z axis linear guides are located at the center of the bed. I didn't want to cantilever the adjusters out to the far edges, and as a result, adjusting roll moves one edge up and the opposite edge down as the bed pivots on the reference and pitch adjustment screws. Adjustment would be easier if the reference and pitch adjusters were located opposite the roll adjuster, but the adjustment only has to be done once. Putting the reference and pitch adjusters right next to the Z axis bearing blocks makes for very stable positioning and it doesn't require readjustment unless I take the machine apart. I use springs to hold the bed plate down on the leveling screws. If a really massive print were printed off center, it's possible for the spring at the roll adjuster to stretch and let the bed tilt, but in the real world that's not going to happen.

I guess either type of mount would work fine. As far as I can see, both types have a single stable position for the bed at any temperature. I wouldn't expect to be able to resume a print after a power failure if the bed is heated simply because prints are going to come off the bed if it cools while the power is down.

Thanks for the answer guys. I think i've got a pretty clear idea of how i'm going to pull it off. Also i just received a funding confirmation so i'll be working on this pretty soon

@jaydevdave said in Driver on Board Shorts, how to ignore this error:

Error: Short-to-ground on drivers 0 1 2 3 4
Error: Over temperature shutdown on drivers 0 1 2 3 4

I am using Drivers 5, 6, 7, 8

That message indicates that the SPI bus to the on-board drivers isn't working properly. Did you make any modifications to the Duet?

Recent firmware versions allow you to send M569 Pnnn R-1 to disable monitoring of driver nnn.

The probeless probing code assumes that you are going to drop the nozzle until it touches the bed. What might work is to select tool 0, use G10 to temporarily set a tool Z offset of that height, then run the procedure, then set the offset back to zero.

@longb99 I honestly gave up on it, hooked it up to the end stop I believe but I never got enough accuracy for much repeatability. The bed leveling mesh made with the ezable sensor was near useless. I'm using the $25 IR probe from filastruder.com. Works rather well with this and I can print without playing with baby-stepping at the start of each print.

Well, with all the fiddling I do, I need to repeat my "one time calibrations" a lot 🙂

I suspect/hope the nozzles are made on a swiss lathe, I don't know if it's a sound assumption, but it seems to be the cheapest way to make them.

I am one of the original Filastruder Kickstarter supporters (this was 2013) and I am pleased that the company is so successful.

@gtj0 said in Duet2 with 2.0 RTOS looses Duex5 on reset:

It looks like if you reset (M997, M999, etc) a Duet2 with the 2.0 firmware and a Duex5, the Duet2 doesn't recognize the Duex5 when it comes back up. The hardware string just says "Duet Ethernet 1.02 or later" instead of "Duet Ethernet 1.02 or later + DueX5" and commands to motors on the Duex5 are ignored. The only way to get it back is a power cycle. Even rolling back to 1.21 still needs a power cycle to get the Duex5 back.

But you said that rolling back to 1.21 still requires you per cycle it to get it back is that not the same

Ah, sorry for the confusion. Let me clear. When running 2.0 I have the issue. If I roll back to 1.21 WITHOUT A POWER CYCLE I'll still have the issue until I do a power cycle. Then everything's normal on 1.21. This sounds like a 2.0 firmware issue that puts the hardware in a funky state that can't be recovered without a power cycle even if the firmware is downgraded.

@3mm said in Controller Ills:

Still can't cause the Smart-Effector (E3D-V6) hot-end to attain minumum PLA printing temperatures.

Multiple issues like that can be caused by a power issue, either a bad PSU or a bad connections between the PSU and the VIN terminals of the Duet. In the M122 report, what values are given for the min and max VIN voltage?

Hey guys, just wanted to update here.
I got new parts from E3D and now everything runs smooth again, so it was related to the bearing gate issue.

Thx for the tip with the bearing gate.

It's possible to measure the distance to the endstop indirectly. If you do a normal G1 S1 homing move, then when the endstop is triggered the axis position will be set to the limit that you configured using M208. But if you use G1 S3 instead, then when the endstop is triggered the M208 limit will be set to the current axis position instead. So you could use a G1 S3 move at each layer change, then M208 without parameters to display the new M208 axis limits.

I drafted a documentation for people interested:

Thanks!

@dc42 said in Entry-level/cheap Duet board?:

M3D is manufacturing them and handling the pre-orders. See https://fitforlaunch.com/projects/duet-2-maestro.

Thanks for the link, I'd not followed the other topics on the board that closely. I see why you tested it on your Ormerod. Good fit for that!

Perhaps add a redirect on the Duet3D shop to that page unless there are commercial reasons for not doing so?

@monster-delta said in whats more important/desirable/:

The original question was with regards to desktop deltas whether a 250-300mm bed was preferable to a 350-400mm+ print height

If you mean is a 250-300mm bed with modest print height preferable to a 150mm bed with 350-400mm height, IMO yes.
