Re: Software for G80/G81

I use Octoprint and the link below.
Paste your G80 / G81 data there and you get perfect alignment data.

https://pcboy.github.io/g81_relative/

Raw values:
-0.1 -0.03 0.01
-0.01 0 -0.02
0 0.01 -0.06

Degrees:
-72° -22° 7°
-7° 0 -14°
0° 7° -43°

Fractional Turns:
-1/5 -1/10 0
0 0 0
0 0 -1/10

Re: Software for G80/G81

If you feel really adventurous you can try:


# pip install git+ https://github.com/bozzzzo/pinda-measure#egg=pinda_measure
# pinda_measure --help


I recommend doing this inside a virtualenv. It isn't tested yet beyond my mac 🙂

What software do you use to GET G81 data?

I have used the visualizer.....I like taking the data into spreadsheet.

however, how do YOU get the data out of the Prusa i3 MK3?
I use Repetier Host MAC

Yes, well I tried pasting my data into the top box......and nothing.
The bottom box didn't give me any data, no change in bottom box....
I could not figure out how it works.....I'm not a programmer.

Thanks

I will ask my programming expert about this.....but probably won't do this.
I have no idea how to use a Virtual Environment.

I want to know what software you use to GET the data out of the Prusa i3 MK3.

Re: Software for G80/G81

I have used Mesh Bed Leveling, and G81 on three Prusa i3 printers.
I have adjusted the beds for three Prusa i3 printers to within 50 microns variance across the bed. With more iterations, I can get it down to 20 microns maybe.
We have fourth MK3 that I will be working on after snow days next week keep me from going up to the high school where I volunteer with the 3D printers.

I know what to do with the data.

We are using Astroboxes on all of our Prusa i3 printers.
We are not using Octoprint, although I've read that Octoprint is included within Astroprint.
Is there a way to use Astroprint to GET digital copy of G81 data?

Thanks
Richard

Re: Software for G80/G81

The above software talks directly to a serial port with a connected MK3 to issue the commands and get the data. Then it munges that data and shoves it into matplotlib for graphical display

to issue G80/81 and capture the output you can use any software that allows you do something like that, for example pronterface application that is installedtogether with slic3r. you'll get numbers you can cut&paste into your analysis tool of choice.

You don't need to SHOUT... I use Pronterface to issue the commands via the USB cable the first generates the data the other dumps it back to you where you can copy paste it where you like

If you do not have access to a Raspberry and OctoPi then you can use Prusa's "Pronterface" software.
But the data you paste into https://pcboy.github.io/g81_relative/
must have the format below, so you must add "Recv: " to each line.

Try with this data:
Recv: 0.16500 0.18463 0.19991 0.21083 0.21741 0.21963 0.21750
Recv: 0.16046 0.18181 0.20058 0.21676 0.23036 0.24138 0.24981
Recv: 0.15630 0.18067 0.20295 0.22315 0.24126 0.25727 0.27120
Recv: 0.15250 0.18120 0.20704 0.23000 0.25009 0.26731 0.28167
Recv: 0.14907 0.18342 0.21283 0.23731 0.25687 0.27150 0.28120
Recv: 0.14602 0.18730 0.22033 0.24509 0.26159 0.26984 0.26981

Re: Software for G80/G81

You don't need to SHOUT... I use Pronterface

whispering "Thank You" 😉

Re: Software for G80/G81

I use COPY/PASTE to move data from Pronterface to Excel. Not really rocket science.

Re: Software for G80/G81

I smashed together bits and pieces from all the g81 programs I could find: https://github.com/JPTa/g81-to-heatmap-relative
This is the image with all the stuff enabled in same picture (is it too much? :))

It also outputs simple text list of the same value to stdout when run:


Measured distances (in mm):
0.102 -0.027 -0.219
0.018 0.0 -0.085
-0.091 -0.087 -0.093

Bolt adjustments (in degrees):
73° -19° -158°
13° 0° -61°
-66° -63° -67°

Hi JTa, I tried your python script and love it ... I am using the "Prusa Mesh Leveling" plugin in OctoPrint in parallel but when optimizing my Nylock bed I will switch to your script now - much more intuitive in my humble opinion.
THX for your effort!
Cheers,

RE: Software for G80/G81

@tim-m30

And after pasting the values to excel (or Open Office Calc), what? Seems to me that the right excel sheet would spit out the adjustment values in a grid showing either/both degrees of turns and/or fractional.

I was just thinking that if someone has already made the excel sheet, I could ride his/her coat tails. You got it? Will share?

Output like this (or better; this aint totally accurate).

Raw values:
      -0.07	-0.02	-0.01
      -0.08	0	0.05
      -0.09	0.02	0.02

      Degrees:
      50°CCW	14°CCW	7°CCW
      58°CCW	0	36°CW
      65°CCW	14°CW	14°CW

      Fractional Turns:
      1/10CCW	0CCW	0CCW
      1/5CCW	0	1/10CW
      1/5CCW	0CCW	0CCW
