Re: RostockMAX V3 to Duet WiFi conversion instructions

Got lucky, right on my blog post two photos down it shows that orange wire connected to the negative terminal! I've added a note to correct the post. Thanks guys.

Re: RostockMAX V3 to Duet WiFi conversion instructions

Ok, I checked all my photos archive and I have that orange wore on + in every photo. I'm sure the fans worked but the schematics say it shouldn't so maybe I had an elderly moment. Most of the photos were taken on the same day.

I've since completely redone the wiring so I can't compare.

Re: Duet Wifi

Have realistic expectations though, many of the STLs on thingiverse are absolute crap - low polygon counts. You will never get a great print out of an inferior STL file. If you are designing your own models, learn how to tesselate properly-I have a post on my blog about how to get the best results.

Re: Poor 1st Layer Adhesion Between X & Z

This sounds like the "bed tilt" issue that many of us experienced earlier this year/late last year. Using the web based calibration based on David Crocker's implementation either manually (on the SeeMeCNC site) or via the Octoprint plug in significantly improved things. Which version of ca...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

Mike, this is the sort of information I was looking for, thanks! As you know, so many people post comments like "it works" and they are correct - it works for their use case but maybe not others. The range of bed surfaces you list tells me the sensor is not sensitive to the "dampening...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

@leadinglights, what about their ability to handle multiple surfaces and not just plain borosilicate without any changes to probe sensitivity, etc? My experience spans the gamut of bed surfaces AND multiple printers (i.e. different effectors, motion control mechanics, .9 vs 1.8 steppers, bed sizes a...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

Hey Mike, I don't know if you looked at FSRs with the JohnSL interface board. If not, you should. I have been running delta printers using this setup with absolutely perfect results for a couple of years, printing nearly everyday. Other than the initial install, which really was not a problem, I rea...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

Have you looked at FSRs? They are an excellent solution that work under a wide variety of conditions, reliably. There is no reason why an effector/carriage couldn't be designed with an FSR rather than a piezoelectric sensor. But, on to your question, yes F1800 and that is at the low end. The stock S...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

Yes, I've been following closely. Haven't made one yet. I spent sooooo much time trying to get the accelerometer probe to work that I put off dozens of projects. I'll wait a bit and see how this works longer term but I do like the idea and it does seem like it will have the reliability of FSRs with ...

Re: Which upgrades to buy

Bear in mind that we each have differing requirements for reliability and precision. I also have trash80's interface and we collaborated behind the scenes. I also worked directly with the company that manufactures the accelerometer itself. Sure, I can get it to work but any seemingly minor change ca...

Re: Which upgrades to buy

My recommendation, and take it for what it's worth: Ditch the AstroSyns, they are not needed with the Duet WiFi and actually introduce enough wobble to affect part quality (slightly). E3D V6 Universal version WITHOUT the Bowden option - it's not needed. 12 V version Also realize, I gave up on gettin...

I get asked this all the time so here's a little overview on how to go about designing purpose-built supports for your models. You can also use these techniques to add supports to STL models in exactly the same way, all it takes is a CAD program that can open STL files and can generate meshes and sa...

Re: New Slic3r Prusa Edition (rocks)

Are you designing these parts yourself in Fusion 360? If so, THAT's where to design in the supports. That's what I do. Here's an example - the Z shaped part is the support that keeps the inside flat bottom from failing. The part I'm holding is printed with the thin perimeter facing down, like an ups...

Re: New Slic3r Prusa Edition (rocks)

:) No worries. I am just a bit sensitive to some of the crap people throw on TV. It causes immeasurable problems for people, especially those with not a lot of 3D printing experience. It isn't hard to make a good mesh and verify it. TV should pre-verify and not allow crappy STLs.

That's too bad, people really should check their models and fix them before posting. Relying on a slicer to fix a mesh is not something I recommend. But IIWII.

Mine is "green". But, I have to top off with water as it evaporates. I've not had to dispose of the actual coolant since I recirculate it and some gets lost on the swarf when I removed it, requiring me to top off. The residue on the swarf evaporates leaving a greenish powder. My aluminum r...

I agree, if time is money for you, the commercial unit is the way to go. That's why I bought mine originally. I have flood on 2 mills and "shower curtain" enclosures. Works great but I like the fogbuster best
