Davinci calibration app

Davinci calibration app DEFAULT

This is going to be a small introduction/explanation of how to calibrate the XYZ Da Vinci A heated print bed&#;

Basics:

Calibration is a pain and takes time, mainly due to the different triangulation of the screws and triangulation of the measuring points.

It helps to write down all the values given by the screen after pressing &#;auto calibration&#;. These are the distances from the measuring sensor to the measuring points.

Also always ensure the measuring points/metal plates and sensor are completely free of dirt/glue/plastic residue. First time calibrators should have pen and paper handy and note the values and the action taken each time.

There are several methods to calibrate the Da Vinci printers, look up thingiverse for a calibrator using an analog dial, then there is an app in the amazon store, and also the &#;paper sheet method&#;, which lots of people prefer. Search engines help here! This page describes, as best I can, how to calibrate using the built in default method. Patience is a virtue.

 

The Ideal value you aiming for should be around ! The printer will read &#;success&#; if all given values are within 20 of eachother and above /below Higher average value than might make the bottom layer uneven and result in non-sticking prints or other irregularity in my experience. I usually aim for about +- (also depends on targeted output layer height a little).

davinci_measuringpoints Above indicates the output order of readings on the screen.

1 complete turn of the adjustment screw changes the measured value by This means a half turn equates to 25, quarter to etc&#;

The best way to go about this in my experience is to get value (2) to an ideal value of approximately to begin with . (Don&#;t even try to get it spot on, it won&#;t work. anywhere between and is a great starting point)

davinci_screws

davinciscrew_plusminus

Short estimation description of triangulation: The back right screw (A) affects measuring points 1 & 3 mainly.  Increase (A), 1 goes up by about 50/turn, and 3 will go down a bit. The back left screw (B) affects measuring point 2 mainly, but inversely, ie. increase or add to B and the value for 2 will go down by about half the amount of turn.  The front screw, (C) affects pretty much only measuring points 2 & 3, by 50/turn. When I say &#;goes down by half&#; or &#;a bit&#;, usually means around a third+- but I don&#;t have any reference values as I am lazy on detail once I set my eyes on my goal.

#TL;DR


I bought it used from my friend. Before I paid he wanted to make sure I could calibrate it and do some test prints so I could see that it worked.

At first, it always returned:

I observed that the extruder wasn't touching the bed when it was trying to calibrate point 1 -- at this point I can't tell if that is what was actually happening. It also never left the first calibration point and threw the before moving on to the other two calibration points. So we loosened the screws as much as possible, though not so much that the springs lost tension.

I also cleaned the crap out of the metal calibration points (using an eyeglass cleaner cloth and applying a lot of pressure with my thumbnail but also keeping my other fingers underneath the heat bed so I didn't apply too much downward force) on the corners of the heat bed, and scrubbed the shit out of the extruder with the copper-bristled brush.

That still returned all s but at least the printer was finally moving on to the other 2 callibration points and not stuck on the first one, so we tightened each screw by the same amount because the bed seemed like it was generally too high as it was callibrating (it was hitting the pulleys during the callibration process).

That gave us our first reading that wasn't fully error-ridden:

I don't remember what we actually did because we were in full experimentation mode, but here is the sequence of values we got:

We were so stoked to finally get all 3 non'ERR' values that I didn't realize we weren't nearly done. This is what the full screen said:

From that point on, we never saw again. But we did calibrate it about 13 more times with various ideas and hand-wavy concepts that we weren't familiar with.

We called it a night, and slept on it.

Turns out we both slept on it hard. These were our results:

My friend is a wizard, so he whipped up some formulas:

Given that (50 calibration points equals one rotation), assigning the screws to , and and calibration point readings to , and respectively; I believe we may be able to calculate the correct rotations for the screws with these three equations: , and

I came up with these steps:

The Road to Success

The final three values from the previous night were:

I wanted to try out my new steps so I tightened screw A a bit, guestimating how much it would take to get #1 to

I tightened screw A some more (maybe 1/3 turn), tightened screw B too but not as much, tightened screw C too even less.

I tightened screw A 1/3 turn, and screw B 2/3 turn.

I tightened screw A 1/3 turn.

Nice! Now untighten A 1/6 turn.

Cool! Now tighten B 2/3 turn to try to get & to closer values as each other.

Closer! Now tighten B another 2/3 turn.

Even Closer. Now tighten B 1/3 turn.

A mere difference of 4. So it was time to tighten C! By a smidge more than 2/3 turn.

Hmm, my theory is starting to waver I will loosen C by 1/3 turn because I don't know what else to do other than backtrack. Perhaps C doesn't need to be turned as much to get as far because of its positioning.

SUCCESS!!!!!

Topic: Da Vinci calibration calculator

I have a Da Vinci that often needs to be calibrated.

I was tired of trying again and again with the adjustments, so I decided to create a little calculator. You can find it here http://ddd.stefanomenci.com.

It uses data from my , but it should help also with the

Please try it and let me know if it helps.

Re: Da Vinci calibration calculator

Just giving feedback - do not help at all.  I&#;m way off now.  Going to find a paper to wedge and bring it back to reasonable numbers.

Re: Da Vinci calibration calculator

Can I know what printer you have and what numbers you used?

I used it about once a week with my DaVinci and so far I had % success rate.

Re: Da Vinci calibration calculator

I had success with this calculator after entering 7 data calibrations and it seems to work pretty well. I am using it on a Da Vinci I would like to make 2 comments. First, the adjustment screw diagram seems backwards for my printer. I have 2 screws at the back and 1 in the front center. My measurement points are 1 rear right and 2 in the front. I just assumed the diagram for the screws was rotated and adjusted accordingly. The second point is that the program seems to want to calibrate to an offset of I thought that the recommended setting was Overall the program is helpful and I suspect any errors I have were due to approximating how much I rotated the screws.

Re: Da Vinci calibration calculator

prpickett, thanks for the feedback.

I assumed that the Da Vinci was just a smaller version of the , instead I just checked the documentation (http://support.xyzprinting.com/us_en/Support/document) and I found out that the positions of the adjustment screws are inverted, and that the suggested target for the 1 is between and

I modified the calculator. Now there are different images for the 1 and the 2, and the default targets results are for the 1 and for the 2.

Re: Da Vinci calibration calculator

I removed the bed adjustment thumbwheels and marked them with red paint at the 0 and degree positions and with blue paint at the 90 and degree positions. My thumbwheels have 50 ridges on them so this corresponds to degrees per ridge. After putting the wheels back on and running about a dozen standard calibrations (individual adjustments of degrees per wheel) I was able to get a successful calibration of (aiming for at all 3 points) from a starting position of ,, in only 1 adjustment. I consider that very successful considering I used to take at least several tries to get into calibration from much closer starting values. I have since been able to calibrate successfully in 1 adjustment 4 times over the last week. One point to note is that sometimes the DaVinci doesn&#;t seem to get the correct values when probing so if your result doesn&#;t make sense such as a large value change for a small adjustment or increase when you expected a decrease, just run calibrate again without making any changes to verify the result. Also, minor variations are minimized by just doing your setup calibrations with degree adjustments rather than smaller values. I recommend +/- for each wheel individually and then a couple of combinations of 2 or more wheels.

Re: Da Vinci calibration calculator

You should make an iPhone App for this since there&#;s one for android only big_smile (maybe an app with html code) so it could run without internet access. The android app goes for a buck or so (go make some bling bling)

Re: Da Vinci calibration calculator

I would buy a Ios app or even a Windows app. I have a Winbook so either one would work.

You can run Bluestacks in Windows.  It is a free Android emulator and lets any PC or laptop behave like an Android device and run Android apps. I doubt the Winbook can do it as being an emulator it takes some serious resouces. I have a Winbook myself and know its limitations.

Re: Da Vinci calibration calculator

hang on you mean i wasted 6 hrs getting my BRAND NEW A calibrated and their is an Android Ap :S


sorry your calc kept putting my further and further away , kept telling me to add turns

in the end got my spirit leveler then kept winding them back evenly until i was near again on the calibrations  .. 1 hr later started getting pass&#;s

apparently 1 turn is worth 50 numbers ?



Run the calibration and enter the
3 values here:   
Reading 1       
Reading 2    80   
Reading 3       
Adjust the 3 screws and enter
the 3 values here:   
Adjustment B       
Adjustment C       
Adjustment A        56


when infact i had to go back a couple of turns and not ADD degree worth

Re: Da Vinci calibration calculator

Why are you guys using autocalibration? Its terrible. You don&#;t have to do autocal to do manual adjustments. All you have to do is print a sample demo and turn the printer off when it starts printing and manual calibrate.

Re: Da Vinci calibration calculator

Barry that sounds like a good idea, so why not give us specifically what to do (I&#;m totally new to this stuff) rather than just telling us we&#;re doing it the hard way? I for one would REALLY appreciate it.

He is referring to the sticky at the top of the XYZ Printing Da Vinci Section. Provided by yours truly..

Those numbers represent in decimal the distance between the nozzle and build plate. For example would be mm.. Just save yourself a ton of heartache and do this.. It is the correct and tried and proven method of bed leveling.
