@dc42 thank you, I understand.

I built a core xy matchine and had an accident this evening. Mid print someone mistakenly activated auto bed leveling and bad things happened. Is there a way to lock this option out on my panel due or in the config.g so it cannot be activated while printing?

@t3p3tony maybe I am just not understanding something correctly. In my mind if I could home z_max on each screw, it would give the machine a known place to go to after a power loss when there is a print on the bed already. I still want to use the auto leveling and that map could be reloaded at that point. Is there a better way to do this? Or how is this achievable with the Z_probe as Z_min end stop.

Is it possible to use 3 z_max endstops to z home when using the 3 motor bed leveling setup on a core xy system? Has anyone done this?

I had an issue like this on my old Prusa, I changed settings, calibrated, tuned current, tweaked everything. In the end it was a mechanical problem. One of the horizontal rods that my x carriage rides on had come loose in the mount. I guess what I am trying to say is always look for the obvious first, sometimes we overlook the easy stuff because it looks to easy.

@Splic3dBread I used mine for 2 months before adding panel due, it makes it more convenient but it is not needed as the web interface you can do using just the duet is superior to anything else I have used. I spent money on a smoothie board before my first duet and it is sitting unused in a box now with no plans to be resurrected.

One other point I did not realize when I first bought the duet, you do not just get a board you become part of a community, if I got stuck on something I would comb the forums and duet help pages for answers, if I did not find what I was looking for I posted a question and someone in that community has always shot back a suggestion, link or answer to get me moving in the right direction.

I agree with @Danal ,I have a Bondtech QR pushing plastic through a Bowden fed volcano and it has no issues with running a 1.2mm tip at 50mm/s. My biggest worry is my extruder motor overheating so I put a heat sink on it.

AWESOME!!!!

Looking at you prints I can tell you from experience, If you do not give up you will get this, Your stuff looks exactly like mine used to. It gets easier over time and eventually you just look at something and know what to change. When you make changes have some patience and only change one setting at a time in the beginning, then evaluate whether or not your change did what you thought it would.

I am using a Bondtech QR, and it is amazing. I have never jammed or chewed up the filament like I used to on my titan. This was supposed to be a temp solution while I am waiting for a zesty. Now I am not sure if I will go back. If you are gonna Bowden, use a Bondtech QR.

I do petg at 245 hotbed and 85 to 95 bed temp, is on blue tape I use gluestick or on glass I use hairspray

@dc42 said in Microstepping in relation to deviation?:

Deviation visit the root mean square average of the height error at the probe points.

Thank You DC42, Something clicked in my head and I went back and looked at the the repeatably of my trigger height and started messing with the smart effector sensitivity. Correcting this fixed everything. I am around 20um deviation now, Also thank you to everyone else who lent me their guidance.

@dc42 I am using 20 tooth pulleys and have set my steps accordingly, is there possible benefit to me using 16?

@dc42 awesome explanation, similar to the relationship of power factor caused by inductance, you just need to make a cool analogy to describe it like.......

@kraegar I ordered them from rose works ty for the info, I did find a Misumi rail that will work I think. I will share the p/n at a later date if I am successful.

My build is a 1m delta and I am stuck at .045 being the lowest deviation I can achieve. I am currently running 1/32 microstepping with interpolation on .9 NEMA 23 motors. Would there be any benefit to dropping to 1/16 with interpolation.
(On another thread I read about adjusting belt tightness, and plan to do that tonigt)

One other question, can anyone explain deviation and how it is calculated?

When my PETG quality made a major leap it was when I realized that my first layer being to close to the bed was causing the blobs I was seeing in my 50th layer. Once I gave it a little more room I notices my nozzle was not rolling boogers in the wide open spaces at higher altitudes.

Curious what brand PETG you are using. I have used both hatchbox and ESUN, PETG wise, the Hatchbox (gold, white and orange) prints much cleaner for me. I have also switches from a brass nozzle to the copper tinned nozzle and had noticeable improvments.

@mysta thank you, gonna try the mouse one, I think that will help tidy things up.
